=== Configuring your SSH client to only ask every so often === | |||
You can configure your OpenSSH client to only ask for the second factor every so often by using the "ControlMaster" mechanism. To do so, edit your <tt>.ssh/config</tt> to add the lines: | |||
<pre> | |||
Host HOSTNAME | |||
ControlPath ~/.ssh/cm-%r@%h:%p | |||
ControlMaster auto | |||
ControlPersist 10m | |||
</pre> | |||
where you would replace <tt>HOSTNAME</tt> with the host name of the server for which you want this configuration. | |||
