RH 8.0 & networking problems

(1/6) > >>

Ice-9:
Lo all,
I've been away for a while, real life kinda caught up with me, but I'm back now   :D  

Now, I finally managed to get RH 8.0 on my main machine and there's a glitch   :confused:  
Everything works like a charm, except for my NIC's
When the OS boots it hangs for a few minutes on Eth0 and returns a red "FAILED", when I try to configure Eth0 after booting into KDE I can edit fine, it's recognized (Intel Pila 8460c3), I enter all the paramters like obtain IP address by DHCP, the DNS address, proxy server in Mozilla, etc ....
And then when I click "activate" it hangs for a while and says "cannot activate network device Eth0"??????

Now I looked into every option I could find and found nothing wrong (this is the first distro that doesn't le me go online)    :(  

What I did see is that the firewall is on High by default and no matter hwo many times I set it to medium or even disable it, when I go back to check it's back on High security!!
Could that be my problem?
Do I have to re-install and pay special attention not to configure my Nic's during setup?
Is there any config I could edit to set my firewall rules to medium?

Thanks for the help.

voidmain:
Yes it could. It could be blocking DHCP. You can turn if off (temporarily) to see if that is the problem:

# service stop iptables

or permanantly:

# chkconfig iptables off
# service stop iptables

You can check your firewall rules in /etc/sysconfig/iptables configuration file.

You might also want to watch the end of your system log while trying to bring up the interface:

# tail -f /var/log/messages

Thanks for helping void main, but Jezus f*cking Christ, what is this shit?
I sure didn't run into these problems on my PII 400 otherwise I never would've installed it!

# service stop iptables
command not found (user & root)

I can edit my iptables configuration file but I can't post it because I have no access, I can't print it out because my epson C70 (which was apparently configured fine) is only listed as generic printer and refuses to print.
My Windows partitions are nowhere to be found and  I can't seem to add them.

I mean, SuSE had it's imperfections, but I was able to connect to the Internet immediately and browse my lan, Windows partitions had icons on the desktop and my printer worked flawlessly .....

I must be doing something wrong but my newbie ass surely doesn't know what ....
The iptables config file had al lot of REJECT at the end of almost every line.
Think I'm gonna try a re-install.

Did you "su -" or just "su"? If you don't "su -" it will not load root's profile, which means the /sbin and /usr/sbin directories will not be in your path. This is true on all Linux and UNIX systems I have used. But you could still use the full path /sbin/service and /sbin/chkconfig regardless (you still have to be root). By the way, there's a graphical utility for starting, stopping, disabling, enabling services. I just thought you were a little more familiar with this stuff so I skipped the GUI crap which I hate. The graphical menu is "Server Settings">>"Services". This will prompt you for root's password if you are not already root.

I don't know what to tell you on the rest other than I must be the luckiest son of a bitch on the face of the earth because I don't have any problems like this.                I never install the firewall at install time on any distro because I like to go through the firewall configuration and set it up *exactly* like I want. Nah, I'm lying, I have a hardware firewall (Netscreen) so I usually don't even turn on the firewall on my home machines, other than for testing, and I have a RedHat 6.2 box acting as a secondary firewall/gateway, behind the Netscreen, using ipchains. I have multiple layers of security  for VPN into other companies.

BTW, there's a graphical tool to look at your system logs as well. It's "System Tools">>"System Logs". Filter on "eth0" or "dhcp" in the "System Log".

I didn't su- so that's probably why it returned "command not found"    
So I might try it again, but I went through the GUI to configure the firewall, it didn't change a thing.
And btw I checked with a friend of mine, his firewall is on High security too, and he too is on cable so I guess that's not where the problem resides.
Anyway, I'm off trying a little more and then maybe reinstall.
Thanks heaps for your patience void main  ;)
