Secure Shell, of course. Besides the obvious OpenSSH link, this page will hold some of the less obvious (and more useful) stuff:
Resources:
Essentials:
- DenyHosts – block script kiddies and other pests from trying to do dictionary-based attacks on your server (on the internet, nobody knows that you only use key-based authentication – not even morons).
HOWTOs:
- An Illustrated Guide to SSH Agent Forwarding – everything but SOCKS, but pretty useful to hand out to newbies.
- Restricted Shell for scp/sftp
- scponly
- Using ssh-agent
Tools:
Clients:
- PuTTY, Symbian port (updated on Mar 5 for S60)
- SSH Tools – includes a secure VNC client in Java, sources
- MindTerm – oldie but goodie Java applet
- JavaSSH – another (smaller) applet
- MIDP SSH
Libraries:
- org.keyphrene – Python wrapper
- sshfs, a FUSE / VFS -based filesystem layer atop SSH ( FUSE has a BSD port, but I haven’t yet found an equivalent for Mac OS X OS X)
Notes:
Using the built-in keepalive feature to maintain tunnels with a TCP keepalive and a 30s internal (in-band) client active check (will try 10 times before disconnecting):
KeepAlive yes ClientAliveInterval 30 ClientAliveCountMax 10
Speeding up connections to the same host (thanks to Melo):
$ head -3 ~/.ssh/config Host * ControlMaster auto ControlPath /tmp/501/mux-%h-%p-%r
(on my machine the socket file is in 502 – more similar tips here)
