i installed SUN OS , while installing i had given IP and netmask and all required information . now installation is finished . but i cant telnet to the system .
Can you ping the box? I wonder if you're trying to telnet as root, but can't because you only have access as root from the console. If you edit the file /etc/default/login and comment (#) out the line beginning CONSOLE, you should find you can telnet as root, assuming all other variables are OK. Sorry I can't test this as I'm not at work at the moment.
Do you have a /etc/defaultrouter listing?
Can you ping another machine from your new sun box?
If you get an error message something like: "Network Unreachable" add your router/gateway IP address to /etc/defaultrouter.
Yes i have etc/default router configuration. currently i am not on site thats why i cant send more details ( Ken Sorry to be late )
i can ping default GW . but no one can ping the system .
It's probably a routing/netmask issue. Check your /etc/defaultrouter file to ensure you have the correct router (which it sounds like you already have) and check your /etc/netmasks file to see if you have the appropriate NETWORK and NETMASK defined. Check out the new settings by rebooting- it's the easiest way to reset everything IMO.
