(Linux Mint) Connection loss nfqueue
Closed this issue · 3 comments
What happened:
Intermittent connection outage for all programs on the system even though my network configuration did not change.
After I restart Portmaster through the GUI and wait until Portmaster has restarted, the connection works again. Alternatively, after ca. 10 minutes connectivity is restored automatically.
After a few minutes the Status in Portmaster also updates to Offline. I have, at least once, seen that the Portmaster debug info included a Failing: true status about the DNS resolver associated with my router.
What did you expect to happen?:
A stable connection: No connection issues every few hours with the consequence of having to wait or restart Portmaster.
How did you reproduce it?:
Keep the LAN cable plugged in, use my computer running Linux Mint 22 Wilma with the Cinnamon DE.
Then wait until the connectivity loss occurs and notice that no program can access the Internet or LAN, verify via e.g. ping 192.168.178.1.
Additional information:
I had this happen with Portmaster v1 and v2.
DNS configuration in Portmaster seems irrelevant. IPv6 is enabled.
I have Mint's ufw firewall turned off to avoid conflicts. No other firewalls, antivirus programs, or VPNs.
The cinnamon connectivity indicator says I am connected the whole time.
Toggling off and on Linux Mint's network connection setting and restarting the NetworkManager service makes no difference.
Unplugging and plugging the LAN cable back in doesn't fix it.
This issue is not present on a Windows machine on the same local network, that machine also works when Mint's connection fails.
I noticed that when it happens, sometimes even pinging localhost in a terminal fails but pinging the router of the LAN always fails.
Also, Portmaster's Network Activity section shows no new requests after the moment when connectivity was lost. After the connection restores itself (in case I just wait the 10 minutes) the graph in the Network Activity section seems to retrospectively fill in those minutes.
