Question

I have a Linux box and I want to be able to telnet into it (port 77557) and run few required commands without having to access to the whole Linux box. So, I have a server listening on that port, and echos the entered command on the screen. (for now)


Telnet 192.168.1.100 77557

Trying 192.168.1.100...
Connected to 192.168.1.100.
Escape character is '^]'.

hello<br />

You typed: "hello"<br />

NOW:

I want to create lot of commands that each take some args and have error codes.
Anyone has done this before?
It would be great if I can have the server upon initialization go through each directory
and execute the init.py file and in turn, the init.py file of each command call
into a main template lib API (e.g. RegisterMe()) and register themselves with the server as function call backs.
At least this is how I would do it in C/C++.

But I want the best Pythonic way of doing this.

/cmd/
/cmd/myreboot/
/cmd/myreboot/ini.py (note underscore don’t show for some reason)
/cmd/mylist/
/cmd/mylist/init.py
… etc

IN: /cmd/myreboot/__ini__.py:
from myMainCommand import RegisterMe
RegisterMe(name=”reboot”,args=Arglist, usage=”Use this to reboot the box”, desc=”blabla”)

So, repeating this creates a list of commands and when you enter the command in the telnet session, then the server goes through the list, matches the command and passed the args to that command and the command does the job and print the success or failure to stdout.

Thx

I would build this app using combination of cmd2 and RPyC modules.
