Alias to ssh and cd into a specific directory

I'm using the following.

Have a shell command, called myssh, with content:

PROFILE="$1";shift;
DEF="Basic" #the default profile name
echo "tell app \"Terminal\" to set current settings of first window to settings set \"${PROFILE}\""|osascript
ssh $@
echo "tell app \"Terminal\" to set current settings of first window to settings set \"${DEF}\""|osascript

and use bash aliases for the connect, like:

alias ssweb='myssh Homebrew user@web.example.com'
alias ssmail='myssh Ocean me@mail.example.com'

When I want to ssh into the web server, I simply write ssweb in the Terminal and I got the "Homebrew" profile. When the ssh session ends, the AppleScript sets back to the "Basic".

The aliases should go into your $HOME/.profile or similar bash-startup file.

The "Homebrew", "Ocean" etc. are the setting profiles from the Terminal.app preferences. You can also set up different fonts, encodings, etc.

Of course, you can use it directly (without aliases) like:

myssh Pro user@another.machine.example.com
       ^        ^
       |        ssh command arguments
       terminal profile name

In Mountain Lion the sshd configuration (/etc/sshd_config) was changed and sshd no longer looks at ~/.ssh/authorized_keys2 for valid keys.

/etc/sshd_config on Lion (line 46):

#AuthorizedKeysFile     .ssh/authorized_keys

/etc/sshd_config on Mountain Lion (line 48):

# The default is to check both .ssh/authorized_keys and .ssh/authorized_keys2
# but this is overridden so installations will only check .ssh/authorized_keys
AuthorizedKeysFile      .ssh/authorized_keys

If you don’t wish to edit the /etc/sshd_config on the target machine you can either rename ~/.ssh/authorized_keys2 to ~/.ssh/authorized_keys or symlink it.

Symlink ~/.ssh/authorized_keys to ~/.ssh/authorized_keys2

ln -s ~/.ssh/authorized_keys ~/.ssh/authorized_keys2

Rename ~/.ssh/authorized_keys2

mv ~/.ssh/authorized_keys2 ~/.ssh/authorized_keys
