The application constructs the Ethernet frame and send it using the write() function, it is working fine. Since the number of frames that we need to send are really large, by using the write() function it takes long time and the throughput is very low. Therefore I consider using the sendmsg (mainly sendmmsg) to send large chunks of frames in one shot. However these functions are not working with BPF interface and throws the error "Socket operation on non-socket". Here is the used code snippet: std::vector<uint8_t> m_buffer = ...; struct msghdr snd_msg; unsigned char dst_addr[6] = {0x11, 0x11, 0x11, 0x11, 0x11, 0x11}; struct iovec snd_iov[1]; snd_iov[0].iov_base = m_buffer.data(); snd_iov[0].iov_len = m_buffer.size(); snd_msg.msg_name = dst_addr; snd_msg.msg_namelen = 6; snd_msg.msg_iov = snd_iov; snd_msg.msg_iovlen = 1; snd_msg.msg_control = 0; snd_msg.msg_controllen = 0; ssize_t bytes_sent = sendmsg(m_socketFd, &snd_msg, 0); if (bytes_sent == -1) { std::cerr << "sendmsg failed: " << strerror(errno) << "\n"; } else if (bytes_sent != m_buffer.size()) { std::cerr << "could not send all data: " << bytes_sent << "\n"; } else { std::cout << "sent all data\n"; } The error msg: # /tmp/send sendmsg failed: Socket operation on non-socket What is the standard solution to send multiple raw Ethernet frames in QNX?

The old included one was Net-SNMP, you may be able to use an updated version of that. Regards, Nick. Mon, 28 Nov 2022 14:01:46 GMT http://community.qnx.com/sf/go/post122010 Nick Reilly 2022-11-28T14:01:46Z http://community.qnx.com/sf/go/post122009 Hi all, in QNX 6.5 there was an SNMP agent available, which seems to be gone in QNX7.0 (or at least am I unable to find anything regarding SNMP in QNX Software Center and in the documentation). Are there plans to provide an SNMP agent in future versions of QNX or does one need to use external products? If the latter is true: are there any recommendations? Thanks in advance, Michael.

Once that is full then sendmmsg() will return ENOBUFS. The driver will be reading from the other end of the interface send queue and setting up the DMA descriptors. You have no indication of when the packet is actually transmitted. This makes it very tricky to saturate an interface with UDP traffic - if you write too fast you get ENOBUFS and you are just wasting CPU that's probably needed to deal with transmitting, write too slowly and you aren't keeping the interface busy enough. TCP is a lot easier to saturate an interface in that there will be a TCP socket buffer that a blocking write() will not return from until there is space in that buffer. Drivers can set their interface queue lengths, but most will default to 256 packets. I suspect you are also suffering from fragmentation increasing the number of packets, unless you have adjusted the interface MTU.

So I know what to send and when. I can create according to the manual up to 1024 messages with sendmmsg. But I am out of buffers already when I send 20 messages (7003 bytes). Sending 10 messages at once works. How can I debug this and where can I increase the memory/buffers available for this operation? So that I can actually send the promised 1024 UDP messages at once? Is my expectation correct that sendmmsg only returns once the DMA for this bunch of messages is done?

I am trying the BPF way. I have a problem that how to set a BLOCK mode(like socket) when receiving packets. I have find a ioctl command BIOCIMMEDIATE but it says that BPF will return value when the buffer becomes full or timeout occurs which is different from BLOCK mode in socket. Do you have any advice about this?

With this code running in io-pkt then it can cause issues with any packet flow or interface if care isn't taken. If you don't need the full facilities and performance of an lsm-xxx.so then I strongly recommend to stick with the BPF API. It's far better documented and you are running as a normal process rather than as part of io-pkt.

The lowest latency will be archived implementing your complete network protocol as your own lsm-XXX.so. Here the flexibility is very high. For example, if the message passing latency to the resmgr interface of the lsm-nraw.so is to high for your problem, store the frames with your lsm-XXX.so to a shared memory region and use the resmgr interface only for triggering...

I can use both module to send/receive ethernet packets. Which one has better interfaces support?

I tried using libcares provided by QNX. But still facing the same issue. For ping you asked, gRPC is configured for tcp6. And we are using the default address=0.0.0.0 and port=50051. I am able to run the server. I am facing the problem with client. I can see the server if I do netstat command. Please help me to understand the problem, because I am new to Networking. I have attached the logs.

Does the rest of networking work correctly i.e. can you ping things by name? If not you have a fundamental networking configuration problem in your BSP. If that does work but gRPC doesn't work, then I note that gRPC is using C-ares for name resolution which can add complexity. We ship libcares with the curl packages, I don't know if you are using this copy or whether you are building your own. I strongly recommend contacting your QNX technical support person. QNX offers assistance in porting code.

Or is it on something else? 2) What permissions is io-pkt running with - are you dropping root or using some other security setup? io-pkt will create the socket in /var/run when rpcbind does the bind() call.

Try logging with the -C flag on the command line to see what is going on. If you post the start of the logs then we may be able to see what the issue is. Regards, Nick Thu, 26 Sep 2019 13:08:40 GMT http://community.qnx.com/sf/go/post119998 Nick Reilly 2019-09-26T13:08:40Z http://community.qnx.com/sf/go/post119997 Hi Nick, Thanks, I updated software package, now pdpd-avb is working. But I have still problem with synchronization between two processors with QNX7 one act as grand master -G flag and second as slave -g flag. I can see ptp packets on both machines using tcpdump, so it does not seems to be a network issue. Could you share with source code with me or at least version with additional debug messages for aarch64?

Please reach out to your QNX support contact to obtain the latest version which will contain the fixes for this and other issues. Regards, Nick Wed, 18 Sep 2019 13:23:05 GMT http://community.qnx.com/sf/go/post119955 Nick Reilly 2019-09-18T13:23:05Z http://community.qnx.com/sf/go/post119954 ptpd-avb has been updated in recent patches to removed dependency on lsm-avb.so -- you should also update your install to pick up the latest set of patches since there have been many fixes released recently in 7.0 for ptpd & ptpd-avb. There is no need to specify the -e option for s/w ptp -- ptpd-avb (and ptpd) will detect that h/w ptp support is not available in the driver and run in s/w mode. If you have logging enabled, there should be a "hardware time support = 0," log shortly after starting ptpd-avb. example of s/w support startup (no ptp master connected to this target board), s/w mode log is the 1st (init) log on line 7: # ptpd-avb -gCKb rt0 (ptpd info) 13:06:30.341176 (___) (ptpd info) 13:06:30.342176 (___) Starting ptpd2 daemon with parameters: ptpd-avb -gCKb rt0 (ptpd info) 13:06:30.343176 (___) Info: Going to check lock /dev/shmem/ptpd_lock (ptpd info) 13:06:30.344176 (___) Info: Startup finished sucessfully # Timestamp, State, Clock ID, One Way Delay, Offset From Master, Slave to Master, Master to Slave, Drift, Last packet Received 2019-09-18 13:06:30.345176, init (ptpd notice) 13:06:30.346176 (init) hardware time support = 0, (ptpd info) 13:06:30.347176 (init) now in state PTP_LISTENING 2019-09-18 13:06:30.347176, lstn_init 1 (ptpd info) 13:06:33.348137 (lstn_init) now in state PTP_LISTENING 2019-09-18 13:06:33.348137, lstn_init 1 Wed, 18 Sep 2019 13:22:09 GMT http://community.qnx.com/sf/go/post119954 Dean Denter 2019-09-18T13:22:09Z http://community.qnx.com/sf/go/post119953 Hello, Could you help with running ptpd-avb in "software mode" for ?

Has anyone used such server? I found some difficult to understand how to configure the server: it is also not clear the usage of library and its api: can be used to write some agents that can be interfaced to snmpd ?

I'll take a look into that script. We have significant vendor-lock-in with QNX so we will not be migrating anytime soon, probably. Our systems run fairly stable now so I am not that unhappy with it at the moment.

For graphics I can recommend Crank Storyboard. It's solid cross-platform software with various renderers (hardware OpenGL based, software, etc). It's pretty cheap too. It is supported both on photon and screen based QNX versions. Ironically in this context, QNX has generally been pretty good about arranging that binaries compiled for the previous release just work on the new one. I just boxed up Photon from 6.5 (including the io-graphics framework and drivers) into a package we could deploy on our 6.6 platform. It seems to works as well as it ever did in 6.5 (which is to say, there are still bugs that have to be worked around, but it gets the job done). Truthfully we're looking at migrating away from QNX for our future human interfaces; currently we're looking at commodity tablets running commodity operating systems. The goal being that we can focus on writing the UI using FOSS tools without getting bogged down in graphics driver woes or display signal timing issues anymore. > Anyway, we cannot go up to QNX7.0 because of old ethernet, wlan and graphics drivers for the old hardware that do not exist on QNX7.0 and cost a fortune to port (they're mostly closed source to us, otherwise I'd do it myself). The entire thing is unfortunate because I ported everything else to QNX7.0 and it's generally running well. The biggest change is that they completely reworked the PCI server - that cost me the most time. Yeah, I looked over some of the beta release of the new PCI server. I can certainly understand the need for it -- I had to patch in additional IRQ routing capabilities for our hardware to the old server and I can appreciate the desire to reorganize. I'm not looking forward to making the jump; right now our current system is a single platform image using enum-devices to self-configure for whatever hardware it lands on, so we'll either have to build out a new device detection framework or completely rethink how we deploy. -Will Wed, 23 Jan 2019 19:24:57 GMT http://community.qnx.com/sf/go/post119445 Will Miles 2019-01-23T19:24:57Z http://community.qnx.com/sf/go/post119438 Hey Will, > For me, it was a long and sordid tale of woe about trying to track down why a hardware driver we wrote for QNX 6.3 failed to meet its targets on a new multicore SBC using QNX 6.6. I spent a lot of time with tracelogger trying to pin down what was causing the mysterious delays. We have the exact same problem with our EtherCAT driver. We updated from QNX6.5 to QNX6.6.

What a nightmare. > I don't know if it affects other architectures, so far we're still an x86-only shop here. We are also x86-only but from what I've heard so far, it seems like it happens on all SMP versions of QNX6.6. They said they fixed a race condition that was present in the QNX6.5 kernel, and the fix is causing those TLB flushes. So basically they had to sacrifice responsiveness for correctness. I do not know how QNX7.0 performs in those regards. > To be fair, I still have an old copy of the QNX 6.4 kernel sources from way back before BB screwed up all the policies I wish I did too. I don't have any kernel source. Sometimes I look into openqnx on github, but it's old and doesn't map that well onto the newer kernels anymore. >To mitigate the floods we (a) set the runmask on all of our real-time components to lock them to the first core; and then (b) use 'slay -i -C 0' to also lock procnto's non-idle threads to that core as well.

I spent a lot of time with tracelogger trying to pin down what was causing the mysterious delays. (In the end, I never did mange to solve it -- it seemed like there's some kind of intermittent PCIe root complex stall with that board. When it gets stuck, the other core can still access RAM, but any attempt to perform memory-mapped IO through any PCIe port would also stall.) Anyhow, we run Samba on our target boards to provide easy file transfers for Windows clients; and Samba loves to create and destroy processes with a zillion shared objects, so I saw a lot of these TLB flush floods in my traces. I can't speak for other customers, but I imagine that pretty much anyone with a multicore x86 system who catches a process destruction in tracelogger would've seen it. I don't know if it affects other architectures, so far we're still an x86-only shop here. To be fair, I still have an old copy of the QNX 6.4 kernel sources from way back before BB screwed up all the policies, and that was somewhat helpful for understanding what the IPI was meant to be doing. To mitigate the floods we (a) set the runmask on all of our real-time components to lock them to the first core; and then (b) use 'slay -i -C 0' to also lock procnto's non-idle threads to that core as well. By locking procnto's threads, we ensure that CPU 0 can never be flooded out as it's always the *source* of the TLB flush interrupts; those procnto threads will just be preempted by a real-time thread when needed. It's hardly ideal -- essentially only the one core can be treated as real-time, and there's a performance penalty introduced with every procnto call on other cores -- but at least we get one core that we can still rely on. For posterity's sake, I'd also like to note here that I recall reading that QNX 7.0 had a major rewrite of the memory manager, so it's quite possible this issue has been fixed in the current release. I haven't tried it myself -- unfortunately we've still got too much Photon code to migrate to something else before we can look at making that jump. -Will Tue, 22 Jan 2019 18:01:09 GMT http://community.qnx.com/sf/go/post119437 Will Miles 2019-01-22T18:01:09Z http://community.qnx.com/sf/go/post119432 Just as a small followup: I got it to work.

Either open a routing socket and send an RTM_GET message or issue a sysctl for: mib[0] = CTL_NET; mib[1] = PF_ROUTE; mib[2] = 0; mib[3] = 0; mib[4] = NET_RT_DUMP; mib[5] = 0; Probably best to do the RTM_GET because then you can just get the default gateway rather than dumping the entire table and then having to parse out the default gateway.

With "netstat -rn" I can easily get the default gateway, but I need to do it programmatically in C. A simple approach would be to just do a string search on the stdout of "netstat -rn" and find the default gateway. However, our realtime system is really sensitive and easily disturbed by activities like starting and killing processes (this is a whole different story, bottom line, a QNX kernel engineer told us we cannot start or kill threads at runtime if we ever want stable timings). So, is there a way to get the current default gateway, e.g. with ioctl, without launching route or netstat? I found some solutions online but they are Linux only.

At this point lsm-avb.so is deprecated and so will be removed in future versions. I would advise you to investigate these other AVB stacks for any future projects. QNX does support an 802.1AS implementation in "ptpd-avb". While initial versions of ptpd-avb required lsm-avb.so, ptpd-avb has now been decoupled from lsm-avb.so and supports 802.1AS without any need for lsm-avb.so. N.B. For true 802.1AS support you will require both hardware that supports the PTP timestamping and a driver implementing this timestamping for ptpd-avb to function properly. In the absence of these, ptpd-avb will function in a very limited "software" mode, running off the main system timer with the limited precision of the system tick (1ms by default). With a true hardware PTP clock and timestamping network driver, far better precision is available better than 1us - typically a few hundred ns, may be better depending on actual hardware. You are also free to use any 3rd party 802.1AS implementation that comes with a 3rd party AVB stack. For further information I would advise you to contact your official QNX support contact directly. AVB is a very demanding set of protocols and while we have customers shipping successful deployments of AVB, if you are new to QNX it can be challenging.

I am new to qnx OS. We have a requirement to support ethernet AVB on QNX platform. Currently we have gPTP module for linux platform, which uses packet concept for communicating directly to layer 2 but this mechanism is not available in QNX OS. Please let me know if there is any reference manual available for understanding usage of lsm_avb.so. Thanks.

If the link was down, the nicinfo output should show 0 Mb/s. You can prove this by unplugging the link and then running nicinfo again. As far as getting this information in your program, you would have to send the driver certain devctls, so I will have to see if there is some documentation on this. Hugh.

Even then the device is sending the solicitation messages to the other device. According to my understanding if the targeted device MAC and IPV6 address is getting added in the ndp entry the source device should not send the solicitation message either. Is that correct. Please correct me if I am wrong. Please suggest if there is any option to disable the neighbour solicitation message in QNX.

None of the documentation gives you information on how to interrupt the timestamp in the qnet_error log or any of the information that is outputted. I figured out that the first two numbers in the timestamp is related to the days that the server has been up, but I can't figure out the remaining numbers. For example, 47213832: server_lookup(): invalid scoid 121, 120 47 in the first number means the 47th day the server was up. I haven't figured out what the remaining numbers are and I can't find any documentation to help me troubleshoot the issues I am seeing. Thanks for any help or information!

Here's the steps followed during a full run: 1) process procA is launched on node nodeA 2) procA spawns: on -f nodeB scriptB 3) scriptB ends into: exec procB 4) our test/simulation goes on until a good reason for terminating 5) procA sends a SIGTERM to its on child (spawned at point 2), expecting procB to get terminated 6) procA expects SIGCHLD from on, or after a timeout it exits anyway What sometimes happens is: on remains alive with a pending SIGTERM, and procB does not terminate. I noticed this strange message into nodeB sloginfo, in correspondence with the termination attempt: Jan 05 17:09:42 7 15 0 qnet(stats): kif_server@899 kif_server_msgs Overflow(0) Can this explain why something gone wrong in the signal delivery procA->on->nodeB->procB ? Is it a non recoverable qnet error? Is there a way to avoid this kind of error / critical situation? I'm running a x86 system with qnx 6.5.0. If other infos are needed feel free to ask :) thanks in advance!

I would like to be able to run PPS, remote messaging and other features all using QNet (multiple targets) and want to know if Ethercat is incompatible with QNet. - Can QNet sevices (ex.

I've had QNX pppd communicating to Linux pppd over a serial link, so there shouldn't be a problem as long as all the options are setup properly.

PPP does not work the same as it does on Linux. We have decided to port the same PPP from Linux to QNX. Then, we should be able to figure out what the problem is. It would be nice if somebody could point us to the PPP for QNX source code.

Then check QNX have native driver for that chipset. If it is, QNX will automatically give response. What is aim behind this all stuff? I was trying to send data wirelessly. In it, I can help you.

They need wireless communication between QNX Neutrino and Windows PCs. We are doing simulation of Electric vehicle on QNX and Simulation data is stored in .csv file. Requirments of Project, 1. Transmit Real time simulation data to Windows pc over Wireless communication with transfer rate minimum 5MBps. 2. Read simulation data on Windows pc. 3. Develop Real time graph using simulated data on Windows pc. That's why I thinking in this way. If you have better idea , it will help me & I appreciate it.

We support most of the USB/Ethernet dongles that use ASIX and SMSC95xx chips internally, the USB2.0 with 100Mb/s max are better supported than any that are USB 3.0 and Gigabit. We do support some of the later, but more of the former. Alternatively if you have USB OTG then you can run one of the Ethernet over USB protocols like NCM/ECM/RNDIS if you can get Windows to cooperate.

From that link: "The ported drivers that have source publicly available are not currently considered to be supported". Does your board by any chance have a full size SD card slot? Some companies for example TI and Silex have WiFi modules that can use an SDIO slot. We also support some mini PCIE based WiFi modules.

I'm not enabling QNX's IPSec (and actually changed the startup io-pkt-v4-hc command to io-pkt-v4 to try to eliminate any additional behavior). I've attached a screenshot of the output I'm seeing, which shows the AH packets, but in the input hook, ip_p is IPPROTO_UDP (17). I think one thing I'm not unclear on is whether or not something else in the filter chain is modifying the packet before my filter is called. Is there a way to view the actual chain?

Whether you need pfil_ipsec is going to depend on if you have set the "ipsec" option on the command line or not. If the ipsec option is enabled then the fact that it is an IPSec protocol (inner protocol is IPv4, IPv6, ESP, AH or IPComp) flags it as an IPSec packet and the pfil hooks will not see the packet until it is decrypted unless pfil_ipsec is set. If the ipsec option is not set then all packets will be sent to the pfil hooks straight away.

Is this command still relevant in this case? I can't find any reference to pfil_ipsec in the QNX docs or on the forums Wed, 03 Feb 2016 13:43:53 GMT http://community.qnx.com/sf/go/post115662 peter graham(deleted) 2016-02-03T13:43:53Z http://community.qnx.com/sf/go/post115660 You need to add the "pfil_ipsec" option to the command line. From the io-pkt documentation pfil_ipsec (io-pkt-v4-hc and io-pkt-v6-hc only) Run packet filters on packets before encryption. The default is to do it after encryption.

The source and destination are correct, but the ip_p field in the iphdr is only ever IPPROTO_UDP). I thought maybe something above my hook in the stack was de-encapsulating the packet, but I haven't been able to find a way to test this. Any thoughts on where I should look, or other possible causes?

I have already built the boost 1.57.0 binaries. To test the library working, I ran two http server example codes using synchronized and asynchronized writing respectively (as attached). The Sync version runs fine; while the Async one failed at writing. It returned error "Operation canceled". Can anyone point out where I should look for? Thanks.

I found lots of guides on programming with libpcap, but none of them mean anything if I can't access the functions declared in the header. I found the header file and Momentics sees it fine, but when I tell it to include the libpcap.a file I've found (in target/qnx6/.../usr/lib) it does not give a file not found error (meaning it SEES the library), but doesn't load the function definitions (meaning it is the WRONG library), resulting in an 'undefined reference' error.

You could try using the file resolver instead of the ndp (Node Discovery Protocol) resolver. The drawback of the file resolver is that you will need to know your remote MAC addresses ahead of time and have it populated in the file. This resolver will not attempt check for a duplicate name. There does not appear to be an option to disable the unique name check directly. Options that could affect behavior are generic and will affect other behavior as well. res_retries will affect all resolver queries, not just the unique name query for example.

We tried the -n option. However it seems that we have an old ftpd binary (Our HW has QNX v6.3.0 installed). Is it possible to get the latest ftpd binary which supports this option? I also discovered another workaround to prevent reverse lookup. Which is by defining the IP address to host name mapping in "/etc/hosts". This also then works for Telnet and FTP. However the problem with this approach is that we also have to define the mapping of IP address of PC/Laptop which is connecting to our Host and from where we are doing the FTP. Now considering that my Host IP is fixed to 192.168.255.131, i need to create all entries in 192.168.255.0/24 subnet, because i am not sure what IP would be assigned to PC which is connecting to my host machine. Is there any way to define 1 entry for a complete subnet in /etc/hosts file?

Looking at Wireshark Logs i see that the host generates Reverse DNS Lookup packets towards DNS Servers configured in resolv.conf. (e.g. Queries of type 130.255.168.192.in-addr.arpa). I do need DNS Server for Domain Name Resolution however there is no need for Reverse lookups. Is there any way to disable these Reverse Lookups?

I have access to the code and root access to the board but no reasons why things are done the way they are. There is pf.conf on the board it appears the board is behaving like it is using it. However pf or bfp is not a running process. If I try this ... pfctl -d -f /etc/pf.conf pfctl: /dev/pf: No such file or directory So what else on the system could be doing filtering? What other commands can I run to see where the packet get eaten at?

It seems in QNX we can configure multiple logical IP Addresses in Same Subnet on a particular ethernet interface. Now since this is not blocked by OS, we want to somehow control which IP Address the OS uses as Source IP while generating DNS Traffic. Is this possible somehow? Further needed help on another related topic: While we configured the DNS Server IP in resolv.conf: - We were observing that on calling "gethostbyname()" API, OS was generating DNS Request and on not getting any reply it was making re-attempts (6 times or so) before returning failure. - If 2 DNS Server IPs are configured in resolv.conf then we observe that the delay between subsequent attempts further increases with period of each attempt also increasing incremently. - Also we observed that when resolv.conf is in use, then on executing "arp -a" or doing FTP, we see that OS Starts generating DNS Traffic for each IP in ARP Table and there is a delay in output. Queries: - In Linux we know it is possible to control the number of attempts and interval between each attempt by configuring parameters in resolv.conf. Is the same also possible in QNX? - How can we stop generation of DNS Traffic on execution of commands like "arp -a" or ftp? Would really appreciate if you can provide some pointers for these queries.

As there cannot be multiple addresses in the same subnet, one address will always be chosen to access a particular DNS server. Can you explain in a bit more detail the issue that you are facing?

Now i understand that this can be done by using APIs gethostbyname or getaddrinfo. However we have an additional problem to handle. The DNS request sent to the DNS server should use a fixed known Source IP address in the packets sent towards DNS Server. Is it possible to force/specify DNS Service to use a fixed Source IP? We have multiple logical IP addresses configured on an interface. We just want that DNS resolution should somehow be carried out using 1 specific Source IP address in the pkts sent towards DNS Server.

This is the current state. The API isn't through sockets, instead lsm-avb.so runs its own resource manager under <SOCK prefix>/dev/socket/avb as this enables us to meet the low latency requirements in some AVB scenarios even when the main io-pkt resource manager is dealing with another message. Note that an AVB enabled Ethernet driver is also required, this consists of supporting a few new ioctls along with supporting the multiple queues, shapers and time stamping that is required for AVB. Under the avb directory there is a directory of all the interfaces that may be AVB capable. Under each interface is a "time" entry used for 802.1AS packets (driven by ptpd-avb) and then individual streams are opened and closed with the stream name containing the parameters specifying the stream. Stream name is formed as: "DestMac:VLAN:Priority:Subtype:StreamId:BitDepth:SampleRate:NumSamples:NumVoices" 1722 and 1722a Draft6 streams are currently supported and a clock reference stream can also be specified on the command line. Whole packets worth of data are meant to be written and read rather than reading and writing a partial packets. The lsm-avb.so adds the header to the data and transmits on a talker stream with the correct timestamp. For listener streams the data is buffered until the presentation timestamp is reached. We do also have an io-audio driver that makes use of the lsm-avb.so.

Is this "leak" shortly after startup or is it once io-pkt has been running for a while? Also check with "netstat -m" to see if the memory leak is perhaps an mbuf leak. Do you have any ppp interfaces?

I was using NTP to synchronize to a local GPS NTP server (http://www.timetoolsglobal.com/information/gps-ntp-server/) and had similar results to above - specifically synchronizing to a stratum 16 server. It turns out that 16 is an invalid stratum indicating that the NTP server is not synchronized. Try specifying a local clock stratum of less than 16 - say 10. It should then be OK.

I tried to implement Packet Filtering before this posting this problem in Forum, but as it is a Target Board, with very limited permission, and that needs other configuration to be setup like pf.conf etc to use which I am not able to configure, thus that possibility is ruled out.

Using BPF it's possible to send a particular packet and also receive packets. It would be quite simple to build a ping-like application.

To work around this you would either need make sure the interfaces are on different layer 3 networks and setup static routes for each OR you will need to run two instances of io-pkt, one for each interface then you can have both interfaces on the same layer 3 - you will also need to give set io-pkt option "-ptcpip prefix=/altX" (where X is the instance number) for each instance so that applications can target a specific instance: SOCK=/alt1 ping <destination address2> SOCK=/alt2 ping <destination address1> See the online documentation for io-pkt for details.

Using some other approach, such as BPF (seems that may be old) or lsm-nraw, can anyone confirm that they are able to receive Ethernet messages at the application level with timing granularity in the 200uS or better range?

Mon, 26 May 2014 12:15:56 GMT http://community.qnx.com/sf/go/post110486 Gervais Mulongoy 2014-05-26T12:15:56Z http://community.qnx.com/sf/go/post110480 Hi, I have an application that must send and receive various UDP packets (including unicast, broadcast, multicast - it's for a test simulator) within fairly small time windows (500uS or less). I am currently desktop test hardware QNX localhost 6.5.0 2010/07/09-14:44:03EDT x86pc x86. The specific Ethernet adapter info is below. By setting the tick resolution to a small value (around 10uS), and setting the NIC driver in enum to promiscuous mode, and hand-tuning the delay in a timer calls, I can send UDP packets as I need using libpcap, which is what I've done on other non-QNX platforms. However, when I use libpcap to receive packets, it appears that packets are clumped together, and only delivered on specific time intervals (about every 8.39mS on this system). I've tried using both pcap_loop and pcap_dispatch, changing the priority of the receiving thread all the way to 63 (priority seems to make no difference, high or low), and verifying using Wireshark from another platform that the incoming packets are at the expected times and are properly separated in time. The load on the machine during testing is typically very low - hogs reports idle in very high 90s, and the problem persists even when sending very few packets (e.g. one every 5mS). All time measurement in the application code are using CLOCK_MONOTONIC. nanosleep is used on the sending side between outgoing messages, and the receiver is message driven from pcap_loop or pcap_dispatch from a high-priority thread with nothing else (no GUI) running on the box. When I tried to investigate further on the machine with tcpdump, I discovered that the messages shown there seem to be subject to the same clumping: Groups of messages all have the same timestamp, and groups of messages all have time gaps of about 8.4mS. Knowing little about QNX, it looks like there is timing granularity (<>10mS) that affects both libpcap and tcpdump, even when the granularity at the user application level is successfully much less (<>10uS). libpcap normally works wonderfully for what I need once the OS tick is OK (Linux and Windows), but I just need to deliver the application and I'm not tied to it if this is a difficult-to-surmount libpcap issue. Two questions: 1. Where could this timing granularity be coming from, and is there any way to configure or code around it? 2. Using some other approach, such as BPF (seems that may be old) or lsm-nraw, can anyone confirm that they are able to receive Ethernet messages at the application level with timing granularity in the 200uS or better range? What general hardware/OS/software approach did you use to achieve it? Many thanks for any suggestions for solutions or further investigation. I'm stuck!

Blackberry OS probably has one because it needs to be shared/managed across applications, don`t confuse the two OSes ;-) That being said even if there was, Audi might have decided not to use it. Car systems are NOT opened , they are totally proprietary, any expectations you have could turn out to be wrong. -----Message d'origine----- De : marco spinetti [mailto:community-noreply@qnx.com] Envoyé : Friday, March 28, 2014 7:01 AM À : general-networking Objet : Re: RE: gps coordinates Are you telling me that they are not using an api of qnx to get them?

See the attached sample.

It is very strange situation that the Ethernet driver did not prefix MAC and pass it out directly. Does the pfil of QNX is 100% equal to FreeBSD?

We have a lot of those DLink dongles here that we use all the time, so I know that the driver works. I cannot help you with USB problems, so maybe you should post this question on another conference.

This board wasn't recognized and wasn't handled by the QNX 6.4. The test utility "testpmd" sets in general the link up. Did you disable your board by the network configuration of QNX ? Are you using QNX6.4 or QNX6.5 ? There seems to be a conflict in handling of the link status Thanks a lot for your valuable response!

The "pci -v" command lists the Intel Pro/Wireless 2915ABG network card. However, I am not sure how to make it work in the QNX OS. First, is this card supported by QNX 6.5 OS. Next, if yes, could somebody help me with steps on bringing up the wireless interface? Thanks. Mon, 09 Dec 2013 16:43:22 GMT http://community.qnx.com/sf/go/post107312 H. S. 2013-12-09T16:43:22Z http://community.qnx.com/sf/go/post107299 Hi, My embedded PC is running QNX Neutrino OS 6.5 and it has 2 network card with name "wm0" and "wm1". How do i configure them so that they can act as NIC Teaming ? One of the articles that i found from internet (http://www.tecmint.com/ethernet-channel-bonding-aka-nic-teaming-on-linux-systems/) teaches us how to create a NIC teaming in linux. I tried to follow the steps and applied them on the embedded PC but it does not have the path "/etc/sysconfig/network-scripts". I was unable to proceed after that. Can you advise me on how to create OR is it possible to create a NIC Teaming in QNX ?

Supported are all 1GB adapters from Intel. "testpmd" is completely independend from the network infrastructure of QNX Neutrino. Required is at least a dual core CPU and an 1GB Intel Ethernet adapter. Application start for a dual core system and a single channel *I210* adapter e.g.: "testpmd -c 3 -n 1" For a different Intel adapter must be specified its PCI sub device ID by the -D switch: "testpmd -c 3 -n1 -D nnn" ("nnn" hex number w/o "0x" prefix) The application terminates with an abort() call if the requested PCI adapter couldn't be found ... Start and stop of the "sniff function": *testpmd>*set fwd rxonly *testpmd>*start *testpmd>*stop Start and stop of the "UDP packet generator ": *testpmd>*set fwd txonly *testpmd>*start *testpmd>*stop The maximal number of packets/sec is limitted to 40.000 packets/sec by a nanospin() delay of 20us. (Slower networks creates dropped packets .. "testpmd" must be used carefully on your own risk) There are a lot of additional test cases included ... some are not supported because of architectural differences between QNX6 and Linux Only the "Link status change" interrupt is currently supported. Please let me know if there are issues with your 1GB Intel adapter.

An individual has a different entity with different thoughts and perceptions. If you ask one person to search a picture from internet, he will search it with a keyword which he thinks better to suite the subject. Similarly if you assign this job to 10 people, all 10 will search in different ways. Captioning is done to satisfy the needs of people with different taste and viewpoints. With the help of captioning, all tem people will get their search even if their way of searching is different. You can now find various facilities provided by closed captioning US with regards to financial presentation captioning. <a href="http://www.closed-captioning-us.com/Closed-Captioning-Services.php">closed captioning Company</a> Wed, 13 Nov 2013 12:34:39 GMT http://community.qnx.com/sf/go/post106738 Jackson Ben 2013-11-13T12:34:39Z http://community.qnx.com/sf/go/post106564 Hi, according to http://www.advantech.de/products/QNX-Evaluation-Kit/mod_d208b14e-93e2-40b5-afc1-9482b563716d/News/A1EACAA1-4FF8-46AE-963A-42A3739F9B21/ Advantech offers support for the Q87 chipset with the AIMB-584. Does the latest version of the "x86 BIOS Board Support Package QNX 6.5.0 SP1" already support the Q87? At least in the latest BSP source code I found the HW support for "Q87 Express LPC Controller" .
