| sveinse | My server accumulates a lot of deprecated ipv6 addrs. Isn't there a cleanup in 20.04 that deletes old obsolete addrs? | 10:07 |
|---|---|---|
| sveinse | I have an ISP that assigns prefix via DHCPv6-PD and due to router restarts and we had a day with lots of changing ipv6 prefixes. But that's a week ago, but they are still all listed in all of the ubuntu servers. Do I need to clean them manually? | 10:09 |
| sveinse | I see that ip addr reports a "valid_lft" field in secs for each addr, and that its very high. Where is this number coming from? The external PD or is it an ubuntu setting? | 10:12 |
| xnox | sveinse: https://datatracker.ietf.org/doc/html/rfc8415 skimming through it implies that the dhcp server issues valid & preffered lft for prefixes and autoconfigured ip addresses. I don't think we specify anything special. | 10:16 |
| xnox | it does matter what lifetimes your router got; and which lifetimes machines got from router. | 10:16 |
| xnox | i suspect ISP was giving out long lasting lifetimes..... | 10:17 |
| sveinse | xnox: yeah, I think that might be correct. Thanks. 300k seconds remaining on something is very long. Must debug the PD packages from the ISP I think | 10:19 |
| rbasak | 300k seconds is less than half a week. Not too long on the timescale of some TCP connections that some might want not to vanish. | 10:30 |
| sveinse | rbasak: I can't see there is any TCP connection remaining if you've lost your former PD and route. I believe the ISP router won't know how to route the IP packages (I think). | 11:00 |
| patdk-lap | your server wouldn't know the route has gone missing | 13:38 |

| Comnenus | Anyone know if this packaged anywhere? https://github.com/Scribery/tlog | 20:05 |
| Comnenus | I have come across this, but in 20.04 sssd-common is at 1.16, and this doesn't seem to be part of it? http://manpages.ubuntu.com/manpages/focal/man5/sssd-session-recording.5.html | 20:16 |
| sarnold | Comnenus: sssd is at 1.16 in 18.04, 2.2.3 in 20.04 -- https://launchpad.net/ubuntu/+source/sssd | 20:17 |
| sarnold | Comnenus: but of course if tlog isn't packaged at all, it might be moot | 20:18 |
| sarnold | Comnenus: there's a pam_tty_audit(8) but I've never tried it | 20:18 |
| Comnenus | sarnold: hmm...... | 20:24 |
