Specifying ciphers and protocol 2 in .ssh/config

Question

I would like to be able to specify in my .ssh/config file that ssh uses protocol 2 (command line argument -2), and which ciphers to use with it.

The following does not seem to work (I get bad configuration option: Cyphers)

Host XXX HostName YYYY User ZZZZ Compression no Cyphers arcfour,blowfish-cbc ControlPath ~/.ssh/%r@%h:%p IdentityFile ~/.ssh/seas/id_rsa

Also, how do I know which version of ssh (or OpenSSH) I am using? which ssh or man ssh does not reveal much information.

Reread your post. You spell ciphers two different ways. Hint: the spelling you used in the config file is incorrect. The manpage you are looking for is man ssh_config. — jordanm

Thanks @jordanm . I feel dumb. man ssh_config was helpful though ( I was looking at man ssh) — Amelio Vazquez-Reina

Cyphers should be typed Ciphers
To specify a protocol use the syntax: Protocol X where X can 1 or 2 (2 is the default)

Try man ssh_config
