I have an IBM x330 with RedHat 7.3 that I recently built that appeared to be working fine, but now I appear to have problem connecting via telnet.

No matter which machine I try to use( I have tried this with SuSE 8.1 and W2K Pro), I cannot log into my RedHat machine via telnet. I can ping my machine from anywhere, and I even establish the connection, but when I try to log on as root, the password that I have given it will not log me on, even though it works when I try to log in directly. I went into /etc/xinetd.d/telnet and .../wu-ftpd to make sure that both files read "disable=no" and I also restarted the xinetd service, but that did no good. I also cannot log in via ftp.

I have had this problem before, and I think all I am doing is forgetting to do one little thing, but I cannot remember what it is.

Anything you do that leads me to an answer is, as always, greatly appreciated.
