Solutionnslookup
nslookup
also can you ping the remote servername ?
sounds like the error *could* be a dns issue if this is configured.
Also what's the contents of /etc/nsswitch.conf ?
lastly the entry from /etc/hosts.

Re: Telnet error
Check also permissions of the /etc/hosts, /etc/resolv.conf, /etc/nsswitch.conf files.

Re: Telnet error
First thing you should check is /etc/nsswitch.conf. Look for the entry hosts. It will be like this..
hosts: files [NOTFOUND=continue] dns
if files is first, then add the entry in your local /etc/hosts file.
if dns is first the entry should be added in DNS server.
Change the /etc/nsswitch.conf as per your requirement.

OK, so you've two servers, HP2087 and FILES?
You did and nslookups above on HP2087?
I take it that "telnet FILES" is the one that doesn't work?
Telnet 10.3.90.98 does work?
In any event, get into the other server and do the nslookups there as well...post the results...
If you are supposed to be running DNS, then you will need to set up the nsswitch.conf file. You can use one of the existing ones as a model....
Then check the post above about the host file / dns issue from Ganesan.

Re: Telnet error
from server1 to server1
or
server1 to server2 ???
on server1 -> does nslookup server2 work?
(same for the other server?)
If not, check if server2 is in /etc/hosts of server1 and vice versa.
Hope this helps!

Torsten.

Re: Telnet error
HP2087 at ip 12.5.98.17 -and-
HP11 at ip 10.3.90.98 ?
and you can telnet from HP2087 to HP2087?
and you can telnet from HP2087 to 10.3.90.98?
and you *can't* telnet from HP2087 to HP11?
while logged in to HP2087:
nslookup HP11
nslookup 10.30.90.98
while logged in to HP11:
nslookup HP2087
nslookup 12.5.98.17

Re: Telnet error
You should really better explain the situation!
A windows PC will probably ask DNS to resolve the hostname.
Check with - guess what - nslookup from your PC!
If this gives no result -> DNS doesn't know your server -> use IP or make the server known to DNS!!!
Hope this helps!
Regards
Torsten.

Re: Telnet error
The POINT is that your are telnet'ing between two boxes...not back to the client itself.... now if you would get on with answering the questions posed instead of arguing semantics, this might get fixed......
so.....on the windows box, when you do
telnet hostname
WHAT EXACTLY DOES IT SAY!!!
same for
nslookup hostname
and
ping hostname
