[rancid] .cloginrc add method hostname {ssh:-port} for mtlogin/mtrancid?

[Michael Newton]

If you’re looking to connect to a custom port number, this is what we do. Not sure if you can use it or not, but thought it might help someone.

/var/rancid/foo/router.db:
host.example.com:2222;hp;up;HP switch 22

host.example.com:3222;aruba;up;Aruba switch 32


/var/rancid/.cloginrc:
add sshcmd       *   {/usr/local/bin/sshport}


/usr/local/bin/sshport:
#!/bin/sh

#host is the last argument passed

FULLHOST=${!#}

#check it for the colon

if [ -z "${FULLHOST##*:*}" ]

then

#stuff left of colon

HOST=${FULLHOST%:*}

#stuff right of colon

PORT=${FULLHOST#*:}

else

HOST=$FULLHOST

PORT=22

fi

#now remove the original host from the arguments list

#??? magic! 

ARGS=( "$@" )

unset ARGS[${#ARGS[@]}-1]

ARGS=${ARGS[@]}

/usr/bin/ssh -p $PORT $ARGS $HOST

 will get there, eventually :)

 grumble.  it needs to match the port below; i think this change is the
 missing bit.  sorry

 I found the relevant line next to the previous backport,
 but this change causes all ssh contacts to fail even the 'up' test.
 
 what is wrong with compare ?
 
 lukasz

would this mean that the default ssh method would need to be {ssh:22} with this change? 
so that the one with {ssh:65122} will be an exception ? 

or might the order of 'regexp {...} methcmd suffix port'  matter then?

sorry for stabbing in the dark :)
