Secure Shell Communication

Secure Shell Protocols

Note: There is no TELNET nor FTP access to our computer systems. Please use SSH instead!

Secure SHell (SSH) provides secure, encrypted network communications. The applications which are part of SSH provide similar functionality to a number of traditional, insecure UNIX networking protocols.

In order to protect our computer systems and users from outsude tampering, we only allow ssh communications between our computers. The standard insecure UNIX protocols have been disabled.

The following insecure protocols are not available. Please use the equivalent SSH protocol instead.

Function Insecure Protocol
Disabled
SSH Protocol
Required
Remote login access telnet ssh
Remote login access rsh ssh
Remote file copy rcp scp
Remote file copy ftp sftp

Secure Shell Utilities - Downloads

Windows
There are equivalent client programs for MS Windows. These utilities are:

  • For ssh: putty.exe
  • For scp: pscp.exe
    Putty.exe,pscp.exe (and more!) can be downloaded from Simon Tatham's Putty Page .
  • For an excellent GUI-based ftp and scp: winscp.exe
    Winscp can be downloaded from SourceFource.

Unix
OpenSSH is a free implementation of SSH that is available for most UNIX and UNIX-like platforms. If your UNIX operating system does not support OpenSSH already, you may obtain the programs and further information from the ssh website.

Macintosh
Mac OS X is a UNIX operating system and supports SSH communications by default. All of the SSH UNIX utilities are included in Mac OS X. For older Macintosh Operating systems, NiftyTelnet supports both remote login access and file transfer capabilities.
