I've already set Linux to use DHCP.

The hostname in Windows is the same; "John".

It is possible to ping 127.0.0.1 and my static IP if I set one.

Yes, there is an interface I am allowed to access for my network at 192.168.1.1(the router's IP).

I'll try running the script later.

For Patrick, here's the ouput of ifconfig:
Code:
ifconfig -a

Just another shot in the dark, I took a quick look at drakconnect - I take it the when you use it in the what connection do you want to configure bit you are choosing LAN Connection and not anything else, probably are but you never know.

I see a couple of things that are strange in your message file. Can you grab more information from it?

In another console type

tail -100f /var/log/messages

And then try

ifdown eth0; sleep 3; ifup eth0

The information you got via tcpdump is interesting because it looks like it's trying to find the gateway (ARP requests for the mac for gateway) but isn't getting a response. Can you ping 192.168.1.156?

Try running tcpdump with the -n option (tcpdump -n -i eth0) so that it doesn't try to resolve names.

The fact that you have eth0:9 (a virtual interface) means that you weren't able to get a dhcp address from your network. Very interesting...

It looks to me like maybe your router is really at 192.168.1.212. If that is true then you need to change the GATEWAY=192.168.1.1 to GATEWAY=192.168.1.212.

<edit> Or I think maybe your IP was 192.168.1.212 and not 192.168.1.150?

The thing is you don't need alot of complicated routing tables to ping that router. If you assign an IP to the NIC that is on the same network you should be able to ping the router.

I stop my network and with no routing table at all, I can assign an IP to my NIC and I can ping my router. Maybe this will help you understand better.

Code:
# service network stop
Shutting down interface eth0:                                   [  OK  ]
Shutting down interface eth1:                                   [  OK  ]
Shutting down loopback interface:                               [  OK  ]

I think you need to look at the router configuration carefully. What about the HW address did it somehow get changed. If your router is set to filter based on HW address this could be the problem.

Yep, I'm choosing LAN Connection.

That was my IP a week or two ago; my DHCP lease changes every three days or so.

I'm setting up my network via the method you use; it doesn't work. I'll try removing an entry I made some time back for my NIC to see if it helps, although I doubt it since that entry was made after the problems started.

What does that mean? Exactly what method are you using and what are the results including any error messages.

Try a ping scan of the network:
ifconfig eth0 down
ifconfig eth0 192.168.1.2 netmask 255.255.255.0
nmap -sP 192.168.1.0/24
Does it show any IP's as being up? If so thats probably your router. If not then check your iptables or any other firewall and check the routers configuration.

Would you mind posting your configs for the network interface? The files in question would be under /etc/sysconfig/network-scripts/

I'd like to see a listing (ls -la) of that directory and if you can list the file (cat ifcfg-eth0) that would be enough for this round... =)

I'm sorry it's taking so long, but hopefully we'll figure it out.

I hope we can figure this out. So frustrating!!!

The only thing that currently stands out is that DHCP_HOSTNAME should in your case be "john" since that's the name of the machine. Did you set this up via the mandrake control panel?

Try making the change to the file by hand - you could just make it blank.

Type the following:

vi /etc/sysconfig/networking-scripts/ifcfg-eth0
5 j 2 w D A john <esc> : w q

ifdown eth0 ; sleep 3 ; ifup eth0

The 5 j will move you down 5 lines, 2 (w)ords, (D)elete until end, (A)ppend at end of line - john - escape key, colon (w)rite (q)uit.

I doubt that's the problem... but lets try that first and we'll test other items afterwords.

When you use dhcp you don't get an IP so I would agree you need to change the DHCP_HOSTNAME=
Anytime you make changes and want to see if it helped do this:
service network restart

If the above does't fix the problem could you post both these one more time:
/etc/sysconfig/network
/etc/sysconfig/network-scripts/ifcfg-eth0
