We do something that sound like what you want, which is to come OUT through a
firewall you have no control over. However, our system does make regular
outgoing FTP connections which helps.
The steps it does are:
* Outgoing FTP to send latest data to our FTP server.
* Try to get by FTP a file called Command. The contents of the file is
executed, allowing us to do remote diagnostics or update. It is not an error
for this file not to exist.
* If we want interactive access to the system, the Command file contains a line
like
ssh -NnR 2000:localhost:22 This assumes outgoing access on
port 22 is permitted which is usually the case.
We can then get full interactive access.
Is that what you want to do?
