HOWTO: Speed up SSH login

Jacky_J · 03:26 PM

If you execute the command:

Code:

ssh username@hostname

and it takes a good 10-15 seconds to prompt you with a login/password, and you don't want it to take 10-15 seconds, then you've come to the right place.

You can blame IPv6 for this. Execute:

Code:

ssh -4 username@hostname

Note the -4 argument. This forces ssh to use only IPv4. If this doesn't speed it up, then you're probably out of luck.

Now, if you don't want to type -4 all the time (or are using CVS with ssh), edit your ssh_config file like so:

Code:

sudo gedit /etc/ssh/ssh_config

add the line

Code:

AddressFamily inet

Now you're set.
