Network connection issue

I have 2 machines..one has Linux and the other Solaris 10..in both I am not able to get a network.
Both are connected to a LAN. When I try to ping, for the linux machine it sends packets but no response...server is not responding.
For the Solaris machine it gives an servername not known msg.
Kindly help me with this one.
Thanks!

Do you have actual connectivity on the machines? try typing ifconfig and looking at the configuration for your network. Is it configured propery?

Also, do you use DHCP for IP allocation, or manual? Do you have a DNS server setup on the network? Are your hosts files correct?

ifconfig -a just gives me the loopback address..127.0.0.1
I feel its an issue with the network card...mebbe it doesnt have the drivers for Solaris

may be you havenot configure your network card,
so just allocate a ip to your machine, and then it will be ok

In Solaris you need to plumb the interface;
ifconfig <interface name> plumb

Try prtconv -D

You can also look in /etc/driver_aliases for the alis to the nic -- provided you know what it is.

Cheers.

canyou show me what i have to do in steps if it isn't to much to ask??
