Also, do you have access to the gateway?

The server is at a remote site therefore I cant connect my laptop.
But i think that once i used the same ip as the server and later a different ip.

I have the arp from the server and something is going on...

network-scripts]# arp -v
Address HWtype HWaddress Flags Mask Iface
10.18.110.1 (incomplete) eth2
172.21.65.23 ether 00:1B:78:58:ED:51 C eth1
Entries: 2 Skipped: 0 Found: 2


I belive that the incomplete part could be a problem but dont know how to
trouble shoot it.

This server had bonding setup at first and later I removed it by simply deleting the ifcfg-bondx files.
But It seems like the MAC in the eth1 inteface still has to do with bonding?
In the output of ifconfig I cant see 00:1B:78:58:ED:51 but in the arp it is there.

I looked in another similar server that uses bonding and it had the same MAC 00:1B:78:58:ED:51 as this one. Strange ?

Thanks in advance.

Hi again.

I loked a bit closer to the ifconfig
eth2 Link encap:Ethernet HWaddr 00:1F:29:5D:B9:89
inet addr:10.18.110.23 Bcast:10.18.110.255 Mask:255.255.255.0
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
Base address:0x5000 Memory:fdde0000-fde00000

And now I see that the interface is up but there is no RUNNING.
I belive that has something to do with my problem.

With mii-tool I can see that the interface nogotiaces a speed and half duplex and so on. But it seems that something could be bad anyway.

Think that I will have to go onsite and check hardware.

Well we replaced the network card but nothing changed.
HP confirmed that the driver used is the correct and latest version.

Any ideas ?

Solved.

This was solved some time ago but I failed to post until now.

We replaced the NIC another time, this time for a 2 port model using the
same chipset and driver as the 4 port model.

Now it worked fine.
I belive there was a problem with microcode on the 4 port model or something liket that. But HP failed to send me 4 port model with different microcode.

So the resulution was replacing the NIC 3 times.
