connectivity issue!!

Amit Manna_6 — Fri, 19 May 2006 09:53:21 GMT

HI,
I am trying to login from a Sun server to HP server. I am able to telnet from the HP machine to the Sun server.

The IP of the Sun server is 10.221.51.147 and the IP of the HP server is 10.221.51.168.

Cany anybody suggest a workaround for this issue.

Hi

Are you able to ping from both servers?

What about login from HP to Sun?

Can you try ftp between them?

If ping is not working the suspect the LAN or routing issue.

Hi Amit,

Are you able to ping from Sun server to HP Server? Does it have stable connectivity ?

I suspect, it could be an issue with Network connectivity or DNS issue ?

Also, check with syslog

Amit,

You u sure that telnet is working from HP to sun but ping and ftp not working.

Ok try doing the same using IP address instaed of hostname.

can you post netstat -nr of both systems.

It may be due to your /etc/resolv.conf. Check the domain name in that file.

Are you able to telnet the HP server from any other workstation?

IF not, please kill the initd on the hp server, and then restart it:

inetd -k
inetd -c

then rebuild the device files with insf -e

Regards,

Jaime

For the Sun server there is not entry for the ethernet interfaces for the self ip address.
Try a
route add host 10.221.51.147 10.221.51.147

I am not sure of the netmask - if this doesnt work add netmask of 255.255.255.255
