Server Red Hat and error message Destination Host Unreachable

zillah · 27 Apr 2007 at 21:14

The Linux server Red Hat that I have got is giving me this error :

((Destination Host Unreachable.....))

Its NIC is up, and IP, Subnet Mask, Default Gateway is fine, the Cisco switch where it connected is configured correctly, but neither any one can ping this Red Hat Server nor it can ping any one on the same network.

Switch shows green light , that means physical connection (NIC, cable) should be ok.

I even added the default router under the properties of NIC on Red
Hat Server....it didn't make any difference.

1- Beside the firewall (enabling and disabling) that I have to check[/font]

[font=&quot]2- Can I uninstall TCP/IP and reinstall it again (If that feasible like windows)?[/font]

If I unplugged the server and plugged my laptop instead, they can ping each other (switch and other PCs and laptop)

Any VLANs configured?

Yes, but I am trying to ping a PC within same VLAN.

do you have DHCP running anywhere, if so does it get a dhcp address?

I have assigned static ip address,,,,,,I am going this on the lab (testing envirnoment)

can you post your dmesg ( at prompt dmesg>dmest.txt )
anything in /var/log/messages

I will post these.

Daft question

Which question ?

Read what I asked? Thats what I meant.

I thought when you have said : "Daft question " , to the question or reply that I have raised previously , therefore I have asked you : "Which question ?"

he was saying his own question was daft.

Yes, I got it

Have you checked what he said?

I will do that.
