What is the actual error message? "Doesn't
work" is not a useful problem description.

> A and B are in same subnet.

Just show the IP addresses and netmasks, and
let us decide.

"netstat -rn" on both systems?

Hi Biju,

Check the lan cards configeration on both server. Also check the firewall.

Please check the lan card configuration

If the server multiple lan cards

when you are issuing the telnet command on server B it may be tring to connect through lan card which is not connect.

Also check default gate way configured on server B

Hi Biju,

ok. Server A and B are in same subnet. how about the destination server 172.17.4.27?

is it also on the same subnet of A & B? If this is different subnet then A&B then there is a possiblity of server A has the routing to this server whereas B doesnot have route configured.

Check it..
