# In .ssh/config:
Host *
    ControlMaster no # Connections by default are not a master
    ControlPath ~/.ssh/master-%r@%h:%p
    ServerAliveInterval 60
    ServerAliveCountMax 60

# On normal connections, if there is no master running on the ControlPath it will behave as normal
ssh some.host

# Run autossh (ftp://ftp.sunfreeware.com/pub/freeware/SOURCES/autossh-1.4b.tar.gz)
autossh -f -M 0 -N -o "ControlMaster yes" some.host

# This will setup a daemon that will maintain a "Master" connection to some.host
# Now ssh will use that master channel to connect to some.host
ssh some.host
