I've been following the "Hack Attempts" thread and I've come to the conclusion that having my router route port 22 requests through to my server PC is not safe. Here's my situation. I use my server PC for web hosting and email. Most of my users access their accounts from outside the router (my network is based in my apartment and my wife and I are the only ones who use it here.) I don't users telnetting in because of the security risk (I don't quite understand this, but I've read about it in more than one place, so it's probably true), so I've enabled ssh so that they can log in and change their passwords if need be. They upload their web pages through FTP, supplying their username and password.
ftp also uses clear text passwords. The point of using ssh is to get the passwords and the data out if the clear and into an encrypted channel (just securing some services and not other isn't really enough).
Spammers try to use the mail server every day - I have to read about it in my daily Logwatch, but I don't think they ever succeed. I should probably keep a closer eye on the logs. Is there a way for users to change their passwords through their FTP clients? Or is there a safer way to allow them to change their passwords?
