My problem with log of screen

[kung foo man]

Every cod2 server instance should have its own linux user account, so you can read the log file from each different user home dir, this would resolve the name conflict probably

But the last time I did this I wasn't happy with the capabilities of stone age C tools, so I wrote a Python script which opened a lnxded instance for each user, which then would accept WebSocket connections (user/password protected). So via webinterface a user could enter all kinds of commands and read back the result "in realtime". Multiple users are no problem aswell, you would just accept input from every WebSocket connection and send the output to each connected WebSocket client

Might sound a bit complex, but WebSocket and process read/write libraries and Web dev are so easy nowadays, you might finish that in a weekend
