Topic: Emailing server commands? Anyone made something?

[whiz]

Because of nazi like restrictions on the firewall at work, I can't get SSH or Mindterm to function.
It occurred to me that it would be handy to email commands to the server at home, with it emailing responses back.
It would be great to email something like "nohup wget http://latestiso.com.au/pub/freesomething.iso" to servercommand@homeesmith.com.au and have this new iso at home when you come back.
It would have to have a few authorisation codewords and be restricted in what it can do, but a normal user account would be fine.
Anyone done something like this or know how it can be set up?

you can always host ssh on the sme side with a service you're not using.

for example, if you know ftp port is open at work, host ssh on port 21 on the sme. of course, this will kill your ftp usage.

and just for kicks, try port 5190. large companies often leave this open for their execs.
