Cannot ping Linux Red Had 9.1 machine on my LAN

[Donboy]

I am having trouble pinging a my Red Hat machine that is on my LAN. I have 4 machines on my LAN. 1 of them is running Windows XP (192.168.0.100) 2 of them are running Win2k (192.168.0.101 and 102). These machines are being assigned an IP by the router. The last machine is a Linux box that I have assigned the IP number manually (192.168.0.50).

I can get on the internet with all machines (including the Linux machine) but I cannot ping the Linux machine from any of the others. I have gone into Webmin and went into "Linux Firewall" and told it not to enable the firewall when it boots up, but I am still unable to ping the machine.

I am able to ping any of the Windows machines from Linux.

Any ideas how I can reach the Linux box from the other PCs?

Sounds like icmp requests are being denied. If you can access the internet, then you should be able to do everthing else.

Try refreshing the xinetd service:

# service xinetd restart

Nope. I just did that and it still times out on a ping from Windows.

What do you think about the firewall problem?? Are there any logs I should be checking to see if this is working or not?? Are there ethernet card properties I should be checking to see if they are set properly?? Are there things I should have enabled for this to work?

Sorry if it seems like I'm getting ansy, but I've been fiddling with this for almost a week now and I'm just not getting anywhere. I'm a new user to Linux and I'm starting to think I should have loaded another OS instead. For all the great things I hear about Linux's networking capabilities, you'd think this would be simpler.

When you say that the router assigns the ips for the win boxes and you gave the linux box one manually, are you saying that you have dhcp only for the win boxes? If this is the case, is 192.168.0.50 outside of the range for the dhcp server?

Ok, I think I have it now. The Default Gateway was missing. It needed to be 192.168.0.1 and I didn't have anything. I just decided to start over from the beginning and that's when I stumbled across my mistake. I didn't enter one on installation and never thought to check it again. Hard to believe I was stumped for almost a full week on this problem and it was all my fault. Geez, I need a vacation.

I think the router assigns IPs from .100 to .255 or something like that. So the Linux being .50 means there will never be a conflict with what the router is trying to assign.
