Good day!

I'm using QNX 6.4.0, and I have a problem.

Is QNET over IP with loadbalancing supported in QNX 6.4.0? 

I have 2 computers, each of them has 2 network ethernet adapters. IP protocol is esteblished, IP addresses are set 
manually, netmasks 255.255.255.0. Cross-cables are used: 

hostname = host31                            hostname = host32 

| en0 10.0.3.1 | << ========== >> | 10.0.3.2 en0 | 

| en1 10.0.4.1 | << ========== >> | 10.0.4.2 en1 | 


The aim is to set up QNET connection over IP with loadbalance. So if one cabel is disconnected (for example, 10.0.3.1(2)

 ), QNET has to use another connection (10.0.4.1(2) ). 
I start QNET like this: 
Code:
mount -Tio-pkt -o bind=ip,resolve=dns,qos_verbose=20 /lib/dll/lsm-qnet.so 


io-pkt-v4-hc starts automaticly when system starts up, using devn-el900.so with shim. 

ping 10.0.3.1(2), ping 10.0.4.1(2) work OK. 

_CS_RESOLVE is set to lookup_file_bind 

/etc/hosts (the same on both nodes): 

# 
# Host Database 
# 
127.1 localhost.localdomain localhost 
#::1 localhost.localdomain localhost 

10.0.3.1 host31.lic.ru host31 
10.0.3.2 host32.lic.ru host32 

10.0.4.1 host31.lic.ru host31 
10.0.4.2 host32.lic.ru host32 

Question 1. Is it possible to set two IP addresses for the same host in /etc/hosts in QNX 6.4.0? Are there other ways to

 do it? 

Then. Here is the /proc/qnetstats output :

Question 2. WHY «slot 1 is unused» and «saved our IP address of 103000A to L4 struct»? What about another interface/

IP address? How to point to QNET to use all the interfaces avaliable? Is it possible (over IP)? 

Then, if we execute on host31: 
ls /net/host32 

That's all right. There are two node names in /net folders on both nodes and they are ready for work with them. 
BUT !!! 
Now and forward QNET uses ONLY ONE interface, with IP address 10.0.4.1(2), NOT that one witch has been saved in L4 
struct! 
If anoher cable ( 10.0.3.1(2) ) is connected or not - it has no diffirence. But when another cable ( 10.0.4.1(2) ) is 
disconnected, QNET fails and restores back to normal only when cabel is connected.
