I have a static PD from my ISP (yay!) and I'm trying to hand out static IP addresses to server clients via DHCP, so I can keep them accessible, and get nice automations around DNS and stuff.
Unfortunately, the "static PD" is a tad unstable at present, and sometimes things go a bit awry, and I get a different PD from my ISP. When this happens, I notice that a duplicate DHCP server starts up, serving the new PD to my clients, while the existing one is still running!. This is, as you can imagine, causing some serious headaches. I'm not sure why this happens, but it's happened about a few dozen times since IPv6 started being available on my system - about 3 weeks ago.

Here you can see that PID 63528 and 96030 are both serving v6 on the lagg0_vlan10 interface, and I get a random assortment of IPs as a result, depending which one "wins".
I suspect this is a bug, but not sure how I would go about diagnosing it, especially since it's triggered by the upstream interface getting a new PD.

I am having the same problem under 23.1.11, and it is related to IPv6 renewals on WAN somehow. Here is my current process list.

I suggest checking the system log around the time dhcpd started. On mine, the earliest event today happened on 00:25 (with the second at 1:21). Here is what is in my /var/log/system/latest.log file around that time.

That log also lists the new WAN IPv6 address with the line "/usr/local/etc/rc.newwanipv6: IP renewal starting (new: xxxx, old: xxxx, interface: WAN[wan], device: igb0, force: no)". On mine, that line does not make sense since the new IPv6 address is meant for another interface and should not go to WAN. I still have to dig into that, but I want to post what I found so far.
-
I've worked on such a case with a user. The conclusion was this only happens when Zenarmor is being used and it went away when disabled/removed. I couldn't find a general issue with DHCP service handling.
Cheers,
Franco

Thanks for responding franco. I am not running Zenarmor though, only Suricata.
I found the "new:" address rc.newwanipv6 listed for WAN belonged to other interfaces - igb2_vlan2 and igb2_vlan3. These 2 VLANs are set for "Track Interface". It initially listed the IPv6 for igb2_vlan3, and switched to using the igb2_vlan2 address after I disabled IPv6 on igb2_vlan3. You can see in my ps output one dhcpd process had vlan3.
Since it continued happening with the VLAN 2 address, I changed VLAN 2 to use static IPv6 address when I posted. So now I have no interface set to "Track Interface", and I am currently monitoring logs. It has been 2 days but so far so good.
-
Let me clarify... Zenarmor running which means Netmap is used which means you likely use Suricata with IPS mode enabled?
Cheers,
Franco
-
Yes, I have IPS mode enabled. Do you suggest just turning off IPS, or disabling Suricata completely? I can do either.
-
I turned off IPS and re-enabled Track Interface on both VLANs. The rc.newwanipv6 issue happened. I am going to completely switch off Suricata next.
Update: I notice this issue is consistently triggered by saturating my uplink (~35Mbps) with a TCP transfer (over IPv4). Completely disabling Suricata has no effect. I also tried disabling gateway monitoring since the IPv6 gateway goes offline when WAN renews its IP. None have fixed it. Switching away from Track Interface - either to Static IPv6 or disabling IPv6 altogether - has been the only solution for me so far.

> The rc.newwanipv6 issue happened.
I thought we were talking about multiple dhcpd -6 processes? The situation you describe with rc.newwanipv6 is normal for version < 23.7. I've changed that recently, but you are likely looking at some oddity that has no impact on operation?
Cheers,
Franco

I thought we were talking about multiple dhcpd -6 processes?
We are, but the errors on killing the process and errors in starting dhcpd were generated by rc.newwanipv6. That is what led me to think both are related.
Here are the errors from my testing yesterday. It seems there are multiple rc.newwanipv6 instances running (pid 9906, 38831, 70856), and are stepping on each other launching dhcpd processes.
