dhclient problems on wan since new hardware and upgrade to 2.6.0?
-
what log would be best viewed for that?
I filtered the log for dhclient and that's all i got.
maybe it isn't a dhclient issue at all.

what log would be best viewed for that?
The combined dhcp/dhcpd log.

That's important to know.
As the dhcp lease (WAN) lease is renewed every 2700 seconds, there should be 'dhcp' log lines every 2700 seconds. -
ok this time i filtered out only requests coming from our internal lagg device with !lagg0
hope this is more useful now.

our internal lagg device
That's new.
What is this "lagg" ? ;)
Ok, I know what 'lagg' is, but I never used it. If this is a pair, or more, of WAN interfaces coupled, then it won't be me who will advice you.I didn't count all the dhclient event, but it seems to do its job just fine : every 45 minutes it renews the WAN lease.
When you see connection closed .... exiting. ...... Cannot open or create pidfile: No such file or directory .... PREINIT there was some event that made dhclient to restart
.
This could be the WAN interface that went down, and then up again.
Or some other process that made it restart.This happened at around 05:59:xx - even the dhcpd =restarted.
At that moment 'dhcpleases' (not related) was trying to restart unbound, but it was already restarting ....Btw : Maybe not related to your issues : this :
dhcpleases 72618 Sending HUP signal to dns daemon(1431)is a very known issue.
A process called dhcpleases detects that the DHCPD = the dhcp server, the one that hands out all the DHCP leases to all your LAN devices, created or renewed a lease on one of the LAN's.
To make your "DNS daemon" aware of that event (a newe lease = a new IP, with maybe a host name, etc), it will HUP (restart) unbound (the resolver) or dnsmasq, the forwarder.
In the past, you would loose your DNS cache. That's a bummer. (I'm not sure if that's still the case).
While restarting, you will loose all DNS functionalities. See the resolver.log for what the effect are.Your pfSense DNS, could be unbound, the resolver, or dnsmasq, the forwarder, is restarting all the time. Rarely saw a case like yours, you have probably a lot of LAN devices.
Not 'bad' but restarting such a service every minute is ..... messy.There is only one work around :
to make the "work around" to a "good solution" : add static MAC DHCP leases for all your important LAN devices.
-
no i'm not using lagg as wan devices only as a connection from pfsense to the internal vlan's.
Yes i was aware of the many unbound restarts, but i read at the forums and there are some different opinions on that. :)
I already have my important machines with a static lease, so i give this a try. Meanwhile i use samba as active directory server, and registered workstations should resolve over this dns servers as well. We'll see...
So nothing obviously wrong with my dhcp i guess.
Then i need to find out what is causing that behaviour, maybe dpinger does something dodgy, and doesn't set the gateway back to the fast wan connection after it recovers.

That it is ok ?
We've seen the installation with a loaded pfBlockerNG setup.
It took unbound more then a minute to stop and start again.
New leases came even faster.
At that moment the system has no DNS any more.
I guess we all have the same opinion about the usefulness of such a situation.On your pfSense, there are moments that unbound is restarting every minute.
A restart is typicality 15 seconds - fact check with your resolver.log.This means your DNS is out 25% of the time at that moment.
Let it be clear : if you're fine with that, then it's ok for me.For me, because I've just a bit less then 50 devices spread out over all my LAN's, I entered their MAC etc ones, and now my unbound keeps on humming for days, without being shot in the face x times an hour.
This situation should have been solved ages ago, no different opinions about that neither ;)
Back to your WAN side issue
@elemy said in dhclient problems on wan since new hardware and upgrade to 2.6.0?:
Our internet works fine till isp is going to have packet loss (no pfsense issue, i'm monitoring our ip from a remote server too), after some time it is going back to normal but wan interface is staying on pending until i disable the interface and re-enable it again.
If your uplink goes bad, the link will 'break'.
One of the side effect will be : the dhclient asking for a WAN IP.
If this happens over a - for that moment - bad link, then yeah, dhclient doesn't seem to work well, it will take a long time to get an IP and gateway etc.
Not much you can do on your side to change that. -

no only that they have zero problems with that, i will disable the option and keep an eye on whats going on, but over all you are right, it's messy.
I'm currently using knot-resolver on some machines, but i need to gather some more intel on how that goes.
Maybe it would be an alternative to unbound on pfsense? I don't know about the bsd availability of it.
Knot DNS server is really nice for my needs btw (dynamic dns updates and so on).

Not much you can do on your side to change that.yes i know that, but it wasn't happening before, especially i still can ping our ip from outside of our network, but the link stays down and gateway monitoring says pending with no bound ip, that's why i thought maybe dpinger does something silly there, also the reason i switched from monitoring the isp gateway to 8.8.8.8/8.8.4.4, but that didn't change the behaviour at all.
So i'm out of ideas.
-
so today we had the same problem again, i just changed the monitor ip in the gateway section and it instantly went online.
So i guess dpinger has some trouble to acknowledge that the internet connection is back again and keeps it in offline stat and not switching the gateways back from failover mode.
What would be the best approach to analyze what is going on there?
