Really newb question for networking

Hello, I currently have RedHat 9. 0 Installed on my 2 servers. Both are acting really bizarre at system restarts. I can only setup my network manually, anything else fails AND when I reboot, all the configuration I have went through is ignored and my eth0 isn't brought up.

Hello,
 
I currently have RedHat 9.0 Installed on my 2 servers.
Both are acting really bizarre at system restarts.
I can only setup my network manually, anything else fails AND when I reboot, all the configuration I have went through is ignored and my eth0 isn't brought up.
 
I am a newb with RedHat so, I don't know what logs are okay or not...
I will post all logs needed when asked.
 
I do now that I have these messages in /var/log/messages
Dec 4 09:40:37 ns1 kernel: Intel:registered: PRO/1000 Network Driver - version 5.0.43-k1
Dec 4 09:40:37 ns1 kernel: Copyright :copyright: 1999-2003 Intel Corporation.
Dec 4 09:40:37 ns1 kernel: eth0: Intel:registered: PRO/1000 Network Connection

Dec 4 09:40:37 ns1 kernel: e1000: eth0 NIC Link is Up 100 Mbps Full Duplex
...
Dec 4 09:40:37 ns1 ifup: failed.
Dec 4 09:40:37 ns1 network: Bringing up interface eth0: failed
 
And if I try a services iptables save i get:
Dec 4 10:31:31 ns1 vsftpd: warning: can't get client address: Bad file descriptor
 
Thank you very much.

Try typing dmesg at the command prompt and sift through the "wreckage" of you system startup to find any errors that occured that the system did not tell you about.

OP
dmesg done... not much to show except for maybe:
ip_tables: :copyright: 2000-2002 Netfilter core team
TCP: Treason uncloaked! Peer 24.64.223.205:9600/80 shrinks window 4102834862:4102839134. Repaired.
 
And the ip_tables: :copyright: 2000-2002 Netfilter core team line is shown about three times in the whole text.

Maybe that will be your answer, I don't know. Too bad I'm not an network administrator or else I could help out more.
 
tried

try setting tcp_wrappers=YES in your vsftpd.conf file.
