Is WAKom running? check with 

netstat -atn | grep [yourport] | grep LISTEN

If there is a listening socket than everything should be ok. If it is
not running try a little startup script with content

WAKom startUp

Then you can specify the port of the WAKom by issuing

squeak -headless squeak.image [full-path-to-startscript] port 9090

It should then start on port 9090. So 

netstat -atn | grep 9090 | grep LISTEN

should give the output you need.
