Tow linux boxes can't ping each other


System 1 is called mepis, it has a modem and a nic, running mepis
System 2 is called mepisdell it has a nic, running mepis
Both systems are connected via a dumb hub.
I have successfully setup networking to the point that I can connect to the internet via kppp on mepis and acces the internet on mepisdell, using mepis as a gateway. The problem is that I am having trouble getting NFS to work. I think I have tracked the problem down to the fact that mepis cannot ping mepisdell by name or ip. mepisdell can ping mepis via ip and name.

Here is all the info I can dig up on mepis:

If anyone could figure this out I'd be gratefull.

Sounds like mepisdell may have a firewall running which is unnecessary and may block your pings. You'll see this same problem if you enable the firewall on a Windows XP machine that gets it's internet connection from another XP machine.

Guarddog was enabled on mepisdell, thanks for that suggestion. I can now ping mepisdell with mepis However I still can't get a share mounted with NFS:

?

I hate to be negative but someone has to know what is wrong here.

If NFS works at all, it shoudl be working here, or I"m missing something simple.

It seems the majority of the time I ask a question about Linux I get a quick responce that does not help, like "Go look at the manual" then when I come back with everything that is requested and then some, I get complete silence.

So noone on linuxquestions.org has any clue how NFS works?

Ok, just a simple question. When you did 'mount /mepis' it says taht mount point doesn't exist. This would imply that there is no directory /mepis on your mepisdell comp. Make sure this directory exists first and try again.
