I am trying to access my work PC (Ubuntu 9.04) from home. I do not have control over the router/firewall at work. I am able to establish a reverse ssh tunnel from my work pc to my home PC while i am at work and then use this connection to vnc from home. however i am not able to run the ssh command thru cron so that the ssh tunnel can be created automatically. I have searched the net and tried the solutions provided but they dont seem to work. the ssh command executes thru terminal but does not work thru cron. after some debugging i am getting the error "Host key verification failed"

can somebody please help me

Thanks in advance
