PING 192.168.1.23 (192.168.1.23) 56(84) bytes of data.
From 192.168.1.1 icmp_seq=1 Destination Host Unreachable
From 192.168.1.1 icmp_seq=2 Destination Host Unreachable


tcpdump: listening on eth0
14:51:12.902529 arp who-has 192.168.1.23 tell 192.168.1.1
14:51:13.892560 arp who-has 192.168.1.23 tell 192.168.1.1

This is certainly more encouraging. Where is that 192.168.1.23 address coming from ? You must have entered the number wrong somewhere. Once that mistake is corrected there's a good chance thing's will be working.

I rechecked my configs in gui and found what I think was an errant entry, and removed it.
Now pinging seems to indicate good communications between boxes, returning times in (I think ) milliseconds.

Please suggest a logical next step.

If I am at that point, can you suggest a easy to use and configure app for file sharing? For any thing like remote desktop sharing?

I will go and research any suggestions you may have and get out of your hair for a while. (I hope )

Thanks for your help, it is greatly appreciated

I'd suggest you have a look through the HOWTO's on http://www.tldp.org. There are many on various aspects of networking.

For file sharing the usual Unix/Linux solution is NFS.

The X window system is intrinsically network transparent. Once you know how you will be able to run a graphical program on one machine with the display appearing on another machine. You can also set things up so that one machine can act as a graphical terminal (called an X-terminal) displaying a complete desktop running on another machine.

If you haven't yet done so, I would suggest you start with the most basic network application which is running a login shell on a remote machine. Today the standard applcation to use for this is ssh. Though you won't be needing its security features on your private isolated network, I'd suggest you learn to use this rather than the older insecure solutions like telnet and rsh because virtually any Internet connected host is going to be using it today. A companion program included with ssh, called scp, can be used to easily and securely copy files across machines.

In any case you'll need to get remote shell access working before being able to use remote X window apps.

You should also be aware that neither NFS nor remote X is particularily secure. They're generally used natively only on private secured LAN's. X can be used securely across the Internet by running it through ssh, which provides specific features for this.
