Promiscuous mode on reconnect

Open eex0 opened this issue 6 months ago • 0 comments

Could we fix promiscuous mode on moz0 interface which is re-enabled on reconnects?

if not, for automatically disabling promiscuous mode on the moz0 interface I've added a shell script to monitor and disable promiscuous mode and a systemd service to run it persistently.

Created /usr/local/bin/monitor-moz0-promisc.sh to check moz0 for promiscuous mode every 5 seconds and disable it if detected.

Added /etc/systemd/system/monitor-moz0-promisc.service to run the script at boot, after network and VPN services.

Ensured script logs actions via logger for debugging.

Files: /usr/local/bin/monitor-moz0-promisc.sh: bash #!/bin/bash while true; do if ip link show moz0 | grep -q PROMISC; then ip link set moz0 promisc off logger "Disabled promiscuous mode on moz0" fi sleep 5 done

/etc/systemd/system/monitor-moz0-promisc.service: [Unit] Description=Monitor and disable promiscuous mode on moz0 After=network.target mozillavpn.service

[Service] ExecStart=/usr/local/bin/monitor-moz0-promisc.sh Restart=always

[Install] WantedBy=multi-user.target (will log you out, suggest reboot)

.. Thanks
