[Feature Req] Override config options by cmdline args

[melak]

My particular use case is I have several burp servers dropped here and there, then as my notebook is connected to a particular network (think friends, family, whatnot), backups are taken.

Currently this involves replicating the client config file basically only for changing the server directive in them. The situation would be much simplified if I could override server from the command line. There could be some other options where overriding would make sense, although browsing through my configs, there's nothing else I could think of (someone else probably will, though).

I think @pablodav has a powershell script that does something like that.

My script https://github.com/pablodav/burp_eclient
Doesn't change server, it changes speed and other settings in config before launching burp.

The idea could be used to implement what @melak explains, but probably there are other better ways to do it too.

But I think implementing change of server based on identified network connection is not good feature to add to burp, as it could complicate things necessarily.

The simplest way:

• Create 3 different configurations for each network
• Create 3 different schedule jobs for each config

We do this way and is a very stable one.

You can also log into different log files in this way.
The clients will work when server is reachable.

Option 2:

Setup your script that changes the server in .conf file, like burp_eclient does.
This is not stable way, not recommended at all.

Option 3:

Setup the server in dns in each network.
Use same name on each network
So when working at home / office / etc, client will reach the server based on its name.
You can do similar trick having modified hosts (unstable way).

You may also setup a unique task which will launch a script that detects the current network (whatever fits, ping, detect subnet or else), and then launches a burp instance with a network specific configuration file, eg burp -c burp-network.conf depending on the detected network.

Without thinking much about it, I do think it would be nice to override any config option on the command line.

Something like:

burp -o 'server=1.2.3.4' -o 'port=5071'

Now in git master.
