Re: DNS Lookup. How can we disable Reverse DNS lookup in QNX
Thanks Nick for your prompt response.
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?
