I have this HP-UX machine in another subnetwork. I added a route in this machine as route add 11.255.23.0 11.255.23.1 1 and to make it permanent, I have updated netconf file. After I do 'route -f' and '/sbin/init.d/net start' , I can telnet to this machine from the remote network for first 5 minutes.. after that I'm not able to reach this machine from a remote network.
What could be the problem..
Can these two route entries co-exist in the table ..? results of 'netstat -rn'
11.255.23.0 Boston U 2 lan0 1500 11.255.23.0 11.255.23.1 UG 0 lan0 1500
Apart from the fact that it looks like you're using HP-UX and not linux from the commands and ouptuts given, here's a few words.
The destination host appears to be '11.255.23.xx' (you don't specify), and your own host 'Boston' appears to be on the same subnet.
You shouldn't need to add a gateway for local network traffic.
However, using '255' as part of your network address is just wrong, and I'm amazed it works *at all!*.
The usable range of byte values in an ip address range from 1-254 (in a standard network environment). Usually the values 0 and 255 are reserved for network/broadcast addresses and subnet mask's only.
If using smaller than 24 bit netmasks however, there can be other un-usable values.
The fact this works for a short period of time at all is the miracle.
What are : 1) IP address/Subnet Mask and default gateway for Boston? 2) IP address/Subnet Mask and default gateway for other machine? 3) routing tables for both machines?
