Bedeutet: Secure Shell File System Linux kernel module. Damit kann man via SSH Dateisysteme mounten. Praktisch as hell.

Features:

• file cache for access speedup
• perl and shell code for the remote (server) side
• could preserve uid/gid (root connection)
• number of remote host platforms (Linux, Solaris, Cygwin, …)
• Linux kernel 2.4.10+ and 2.6
• arbitrary command used for connection (instead of ssh)
• persistent connection (reconnect after ssh dies)
