How do I configure Telnet to......

How do I configure Telnet to only enter a users home directory? On FTP I just used the chuser file and edited the vsftpd.conf file, but I can't find a conf file for Telnet. Is a conf file used for configuring Telnet? I have been reading for days and have yet to find the answer. I am doing this at my college for a web programming class. I have most of everything configured other than some things on Apache for security. Any advise on the Apache configuration would be great too.

We plan on mirroring different versions of Linux that we get approved for and I will need to have the Apache configured in a way that is secure yet stable and reliable for when that happens.
My main concern now though is Telnet and making sure that the students can only access their home directories.

If your only wanting the users to be able to access their home directories, you'll need to chroot them.

man chroot for more details.

Though as I tell anyone this using telnet, you might want to consider using ssh instead, as its more secure than telnet. Telnet is not encrypted and anyone can easily obtain any information passed to and from on the network.

Well, I can't answer your question, but I suggest you use SSH if you can. Its much more secure. Telnet is transfered in plain text, so any sniffer on the web can pick up everything. SSH is encrypted.

There is even a great Windows SSH client called PuTTy.

THanks for the help folks. I am still unsure of where to create a chroot list for Telnet or SSH. This server will be used for a class and the students need to not be able to enter all directories, just their own. I got the FTP chroot working fine. THe use of Telnet is to let teh students learn what it is, how to use it, etc. Telnet will only be used from the classroom for basic file listings, etc. Security is really not an issue here, but thanks for spreading the news. I think all users should understand that Telnet is not secure at all. Anyways, thanks for the help and if you have anymore suggetions I would greatly appreciate it.
