Methods for Accessing mtu.net

Here are the different methods that can be used to get into your account on mtu.net. Note that all of these methods are ones in which your password will not be sent in the clear. This change has taken place because of too many people trying to crack mtu.net.

Email

• POP3S, this is POP3 over SSL and is supported by many mail clients, including Outlook Express and Outlook.
• IMAPS, this is IMAP over SSL and is supported by many mail clients, including Outlook Express and Outlook.
• E-mol is a web-based email system that can be used with any mail account and happens to work closely with mtu.net.
• SMTP, this is done via SMTP-AUTH and TLS. Setup your mail client to use TLS and the port is still 25, however the connection is encrypted before your username and password are sent. Due to certain ISPs blocking port 25, port 587 has been opened for SMTP as well.

Shell Access

Shell access to mtu.net is done through SSH on port 4242. Most unix systems already have ssh on their system. Windows users should download and install Putty. There's a windows installer part way down the page. Or they may install ssh from SSH.org (local copy). This version also includes a nice interface for transferring files.

The host key fingerprints for mtu.net are as follows:

• DSA - 2b:22:3c:96:59:08:69:c1:ee:27:44:1c:32:cb:83:8b
• RSA - 70:5d:09:15:e0:74:f1:c7:78:a4:cc:d3:d5:e9:48:5f

File transfer

Since ftp sends your password in the clear, it has been disabled for general users. You'll need to transfer files through a variant of ssh. If this won't work for you contact root@mtu.net for a username/password used by the ftp daemon that is running.

Some users like to use fxp to do site to site transfers. This won't work if ftp is not allowed on mtu.net. However I would suggest those users loging to mtu.net via ssh and then use ncftp to ftp to their favorite site. It has the capability to download directories and does filename completion. If downloads will take a significant amount of time and you don't want to stay logged in, then I suggest running ncftp inside a screen session ('man screen' for more information). Then dowload the files from mtu.net using one of the tools listed below. See the previous paragraph for other options using standard ftp with limited access.

• scp - secure copy. This is for copying of individual files. It is installed on many unix systems. Windows users should goto the putty download page listed above and get pscp.exe
• sftp - secure FTP. This is for copying files in an interactive session. It works just like ftp, only it's secure. It's installed on many unix systems. Windows users should goto the putty download page listed above and get psftp.exe
• For a better interface under windows, try WinSCP or SSH mentioned above.
• rsync - This tool is available on unix systems and can be found with cygwin on windows and even as a standalone app. Instructions for setting it up and running it under windows can be found here. This page also talks about usage that is useful for unix systems as well.
