Describe the Bug:

Hauler is logging to /var/log/messages the following:

Jul 25 00:30:59 hauler NetworkManager[788]: <warn>  [1721867459.5648] platform-linux: do-add-ip6-address[2: fe80::9436:bff:fedc:3d43]: failure 13 (Permission denied - ipv6: IPv6 is disabled on this device)

Jul 25 00:31:01 hauler NetworkManager[788]: <warn>  [1721867461.5670] ipv6ll[4b1e69a26f5728db,ifindex=2]: changed: no IPv6 link local address to retry after Duplicate Address Detection failures (back off)

-

Steps to Reproduce:

disable ipv6 on a rocky/rhel node and install hauler. Then run hauler store serve fileserver and hauler store serve registry

-

Expected Behavior:

NOT logging for ipv6.

-

Actual Behavior:

See errors above.

-

Additional Context:

how is ipv6 being disabled? (looks like the kernel module is loaded). if ipv6 isn't disabled for every network interface i expect that you would see these kinds of logs for every nic that is seen by the systemd service when binding to 0.0.0.0

[clemenko]

I disabled it with sysctl -w net.ipv6.conf.all.disable_ipv6=1.

[dweomer]

@clemenko are you using the systemd unit proposed at https://github.com/hauler-dev/hauler/pull/181/files or something slightly different? please add the unit file that your are using as a comment or edit your bug report to include it as additional context.

err, well, i guess this an assumption on my part. if however you are straight up running hauler store serve ... then nevermind!

[clemenko]

Here is the systemd file

# /etc/systemd/system/hauler.service
[Unit]
Description=Hauler Serve %I Service

[Service]
Environment="HOME=/opt/hauler/"
ExecStart=/usr/local/bin/hauler store serve %i -s /opt/hauler/store
WorkingDirectory=/opt/hauler

[Install]
WantedBy=multi-user.target

basically hauler is assuming ipv6 is there and it is not.

Hey @clemenko, are you able to start with a fresh node of rocky/rhel and test this again and paste the output and commands ran on the node?

[clemenko]

this appears to not be a hauler issue. sorry for the confusion.
