,
1

Hello,

Is there a way to Update Fastnetmon and not brake the Vyos/Router ?

I installed today Vyos 1.4-rolling-202104270417 it has fastnetmon 1.1.3+dfsg-8.1 witch is old and it has bug on it.

The bug is it bans for in/out traffic, by default do_not_ban_outgoing is true ( on ) and not to ban for outgoing traffic and is not working, still bans it, even if i set on the fastnetmon configuration do_not_ban_outgoing = on still same.

the guys from fastnetmon they sayed to update fastnetmon.

And on the vyos we ar unable to install mail function for fastnetmon and we had to use curl with some script in other location to get the reports.

Thank you

Hello @CristianD , try to get fastnetmon from the official git repo and build deb package. By default VyOS get fastnetmon from Debian buster repo.

Use these args to test script and action “ban” - shutdown session
“unban” - no shutdown session
