There also exists the ControlMaster configuration option which treats multiple sessions to the same host as a single connection. With this enabled, you only have to enter your SSH passphrase once per host. Aside from the convenience of not having to repeatedly enter your passphrase, subsequent sessions are initiated much faster (due to not having to renegotiate) and there is (theoretically) less strain put on your network adapter. Note, however, that if there are no active sessions to a host, the connection to that host will be dropped, and you will have to re-enter your passphrase upon reconnection. See the ControlPersist option for dealing with connection persistence. If you're like me, however, you'll use both keychain and ControlMaster (for the increased negotiation speed) :) |
