From man ifcfg
NEEDHOSTNAME
Controls whether or not the hostname is changed to what is sup-
plied by the DHCP server. Valid settings are yes or no, default
is no.
If you have a router between your computer and the dsl-modem you probably don't need this set to yes. Some ISP's want to give your computer a hostname when you connect, but if you are using a router it will get the new hostname.

Also you can remove the IPADDR="192.168.1.101" since you are using dhcp.

Thanks /bin/bash

I made the changes you recommended, but haven't had the time to check 'em out yet. I'll let you know. Been a little preoccupied lately, due to the passing of a close friend. I'll get to it as soon as I can.

Thanks for your help.

BTW, it is a cable modem, not DSL, but you're right. Router is taking care of the DHCP.

I changed the file and restarted the network; no effect.

Nope, nothing comes up. I've disabled both shorewall and iptables from the Mandrake Control Center.
You can't disable shorewall from mcc. You can disable smoothwall from mcc. If you have shorewall running you need to turn it off, or remove it till you get this problem fixed.

That doesn't tell me anything, what file? What was it? What changes did you make? What does ifconfig show? What does route show?

Could you post the two files I've asked you to post?
/etc/sysconfig/network
/etc/sysconfig/network-scripts/ifcfg-eth0

What does iptables -L show?

You should check iptables if you are not sure if you have shorewall running or not. If you have any rules and you don't know for sure what they are doing then run the iptables flush script I posted earlier.

Even if shorewall is running you should be able to clear all rules this way:
service iptables stop
That should set all your default policies to ACCEPT.
The restart the network:
service network restart
If you still don't have an ip then set it manually like this:

# ifconfig eth0 192.168.1.4 netmask 255.255.255.0

If you can't ping the router then do a ping sweep:
nmap -sP 192.168.1.0/24

If you still can't reach the router then use ethereal or tcpdump to verify the pings are actually leaving the port:

tcpdump -i eth0
ping -c1 -w4 192.168.1.1

If you still can't reach the router then you need to go into windows and login to the router and verify the IP. Also check if the router is set to ignore all pings. Check if it is set to filter any IP's of any HardWare address.

What do you mean?

1. No; I've always been able to ping the router from any Windows computer on the network.
2. No, AFAIK, there's no way to do this from the router configuration settings.

You should (from windows) point your browser at http://192.168.1.1 and you should be able to login to the router and verify the settings. You did say you could do that in post #16
Quote:
Yes, there is an interface I am allowed to access for my network at 192.168.1.1(the router's IP).
One option you need to look for is if the router has a group of ip's set aside for static ip assignment. Most routers will have the ability to assign dhcp ip or static ones.

Ah, yes...no configuration on the router's end is required to use a static IP for any computer.

iptables is set to accept all packets.

This is what I got when pinging the router a few times:
Code:

tcpdump -i eth0
tcpdump: WARNING: eth0: no IPv4 address assigned

You need to do ifconfig first:
Code:
# ifconfig eth0 192.168.1.4 netmask 255.255.255.0
# ifconfig
eth0      Link encap:Ethernet  HWaddr 00:4F:F3:C1:0C:0C
          inet addr:192.168.1.4  Bcast:192.168.0.255  Mask:255.255.255.0

Yes, I realised that, so immediately after launching tcpdump, that's what I did. Actually I'd already done it, but it hadn't taken effect, so I had to do it again. As you can see, tcpdump mentions 192.168.1.4.
