Hi Doug,

Since you will be at you ISP, I'll bet they are experts at linux networking. If the linux box is going to be the DNS, when you log into the DNS, make sure and setup all computers that are members of the domain in the DNS. Both Redhat's Gnome and KDE menus allow you to select [System] --> [Network configuration] to get a GUI for network administration. After setting up the member of the network, fire up vi and look at /etc/hosts to see that everything appear correct. I would have someone at the office avaiable to try to login as a test whenever you feel like its all going. If the login still fails, consult with your ISP about how he setup the DNS and what might be required for you to login remotely to the network. Also, clear up the issue about SSH and find out if your ISP can recommend any particular telnet client to access your linux box. I don't know if there will be any windows boxes within the domain, but if so, make sure they are also setup. Most of this could probably be done from the office once you are able to make a connection to the DNS from the office, so the top priority for the trip is to be sure someone from the office can login into the DNS before you return from the trip.

A linux computer can mount another linux's or window's file system using NFS and use the remote file system as a share and it would appear and behave just like a native file system, but I don't know if this is needed, and if so, it could be handled once you can access the DNS from the office. This is the way linux networks its computers using NFS. In this way telnet is not needed because the remote file system would be available to the office computer just like anything within the window's network neighborhood can be accessed. When and if your ready to do this, there is a NFS HOWTO that explains NFS in detail.

Good Luck on your trip and let us know how it goes.
