Re: [ts-7000] Re: Hamachi or VPN

[Michael Shook <>]

Hi Enrique-

I have a rough but useful Python script that polls a Google App Engine (GAE) application (also Python. I like Python.) The GAE app puts up a page into which I can type a command which it sends to the TS-7500 when polled. The script on the TS-7500 executes the command and sends back the result. Polling is ugly but it works.

This is because it would be nice if I could offer remote assistance to my costumers, but most of the time TI guys don't like to open ports or reconfigure anything. The equipment just do some basic logging, and I am using 2.6.21 ts #8 Kernel version, and the full Debian version.

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?
