[SOLVED] RHEL 5.8 doesn't see all network adapters

This is ifconfig results from Ubuntu:

Code:

eth0      Link encap:Ethernet  HWaddr 00:23:ae:99:9b:b7 
          inet addr:192.168.100.10  Bcast:192.168.100.255  Mask:255.255.255.0

          Memory:fe260000-fe280000

In RHEL 5.8:

Code:

eth0      Link encap:Ethernet  HWaddr 00:23:AE:99:9B:B7  
          inet addr:10.90.185.67  Bcast:10.90.185.255  Mask:255.255.255.0
          inet6 addr: fe80::223:aeff:fe99:9bb7/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:2760 errors:0 dropped:0 overruns:0 frame:0
          TX packets:2434 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:1109942 (1.0 MiB)  TX bytes:480153 (468.8 KiB)
          Interrupt:50 Memory:fe6e0000-fe700000

Both also include loopback adapter. So, RHEL doesn't see eth1. How can I fix this?

1. Check "ONBOOT= " status in eth1 configuration file. It should be "ONBOOT=yes"
2. Run command "dmesg | grep eth". It should show eth1 interface.

Sorry for stupid question, but what is eth1 configuration file?

Code:

[alex@localhost ~]$ dmesg | grep eth
e1000e 0000:00:19.0: eth0: (PCI Express:2.5GT/s:Width x1) 00:23:ae:99:9b:b7
