Strange situation with my network link for my Linux server.
I've just installed RHAS 4.0 on my Itanium server. The installation went well. After reboot, I was not able to ping on of the servers on my network or vice versa from my workstation. These servers that I am trying to ping are the ones that I added to the hosts file.
When I ran the ethtool eth0 - The status showed to link. I checked the cable and check the NIC card from back of the server, I can see green light lit up. I even tried a different cable. Being that the NIC does have the 2nd port, so I configured that with DHCP and nothing.
ifconfig eth0 does displayed the correct IP address, Net Mask, etc.
I've installed numerous RHAS 3.0 before and never had this much trouble before.
Any ideas what else I should be looking at.
Thank you in advance.
Jorge

Re: Network Link question
The hosts you pinged are in the same subnet?
Can you ping your configured gateway?
Check on the Server for correct routing.
Do speed/autoneg settings match your switchport settings?
Ask your network guy to double check speed/autoneg and also vlan/trunks etc.
Check if you aktivated some kind of firewall on your new box by mistake.

Re: Network Link question
i got your wrong, thought you have link but can not ping.
To what speed is your switch configured?
Does it match your nic?
What nic / driver do you use?
Can you give the output of "ethtool"?

Re: Network Link question
Confirm with n/w team what is the speed/autoneg setting.
With new model of switches and GIGbit ethernet cards autoneg can be made ON.
But if you have 100MB card , i would suggest to hard code speed/duplex and disable the autoneg. Do the same setting on swtich side
