usage: jamban.py [-h] [--timeout [TIMEOUT]] [--csvfile CSVFILE] [--banset BANSET] [--unban] [--unbanAll] [--kickListeners] [--list]

This script uses nftables to ban clients from patched Jamulus servers.
Get the patched server @ https://github.com/dingodoppelt/jamulus/tree/logging

        Make sure nftables is installed and has a basic ruleset loaded to which you can add your banset.
        See the included example configurations for nftables (ex*-ruleset.nft)

optional arguments:
  -h, --help            show this help message and exit
  --timeout [TIMEOUT], -t [TIMEOUT]
                        set the default bantime, e.g. 30m, 1d, etc. or leave blank for permban (default: 2h)
  --csvfile CSVFILE, -f CSVFILE
                        set path to the csvfile generated by the Jamulus server (default: /tmp/JamulusClients.csv)
  --banset BANSET, -s BANSET
                        set the name of the set to be used for the nftables blacklist (default: ip jamban banset)
  --unban, -u           select addresses to unban from the server
  --unbanAll            unban all currently banned clients
  --kickListeners, -L   kick all current listeners
  --list, -l            list clients as metadata input to icecast
