I am trying to set up a cron job to get a ssh tunnel set up from my firewalled school site to my home. Eventually, I will be tunneling PPPD in from school. It is ok with the school as I am building a network project for my graduation showing how to tunnel VPN traffic from firewalls. I have a roadblock. I am using Redhat 9.0 with every little update that has come down the rhn highway. I can do run my commands manually via a Virtual Console or from an active ssh session into the schoold computer, but it is no go from CRON job at school into my ssh server. BTW, myuser has the correct rsa public key put into authorized keys, so that is not the problem doing a passwordless login. When I execute a command similar to ssh -o "Batchmode yes" -t -l myuser mysshserver.com -R 3128:localhost:3128 everything dies after a succesful login and establishment of remote port forwarding. I get the following error from watching Cron execute the command when I run it from webmin... "Pseudo-terminal will not be allocated because stdin in not a terminal" It was my understanding that the "-t" option in ssh was supposed to over ride the need for a Pseudo-terminal and allow batch jobs to be run. And setting the -v option, I get the following session output.... Output from command /home/myuser/bin/contactsshserver..
