reverse ssh tunnel

Hi,

I have an embedded device sitting out in the field, connected through a USB
cell stick to the internet. In order to be able to reeeaach it, I establish
a reverse ssh tunnel on port 19996 to my home PC to be able to access it.
Now I re-establish that tunnel every 10min to make sure, I have pretty much
uninterrupted access even when the provider decides to change the my IP. Now
I realized that my process list is full of "4383 root ssh -R
19996:localhost:22 -f -N user@host" and netstat is loaded up with
connections as well. How can I ensure this doesn't happen? I only need omne
tunnel at a time open and not 100s... :(

Thanks,
Ron
