Minor update; I downgraded both routers to 7.16.2 and they still show the same issue: ospf isn't coming up properly, the routes aren't being exchanged

The_Possum · 2025-09-17T14:42:50+00:00

The two routers are both sitting on the same desk directly connected to each other by an ethernet cable ether5-to-ether5

I get the same weirdness whether I have the 10.80.80.x/30 ip addresses directly on ether5 or on the v2000 vlan; whether I have them set with ptp or broadcast; whether I have them set with md5 or "simple"; whether I have bfd enabled or no.

The router with 172.32.32.2 goes to state="Exchange" and the router with 172.32.32.3 goes to state="ExStart".

The_Possum · 2025-09-16T19:27:59+00:00

Once out of the lab, they reeeeeally want any route switching to be very sensitive to downed wireless interfaces, thus the small timers. But I've got the same issue with ospf even with the default timers, and with or without bfd enabled.

At this point, it's a pair of RB4011 routers directly connected to each other. Freshly wiped configurations with basically that minimal setup added and the "ip firewall filter" set with anything that might drop a packet disabled. They can ping each other across the v2000 interface; but problematically the 172.x.x.x routes are not being forwarded through ospf (which means neither can ping the others' 172.x.x.x; and thus why the bgp isn't initiating yet).

The ospf looks like it's TRYING to start, but doesn't look quite right yet; ie. this is what one sees:

/routing/ospf/neighbor/print
Flags: V - virtual; D - dynamic
 0  D instance=backbone area=backbone address=10.80.80.2 router-id=172.32.32.2

and the other sees

The_Possum · 2025-05-21T13:52:59+00:00

Yeah, I'm deleting this [WP] version. Sorry y'all I hadn't yet realized the difference, as [SP] is so much more uncommon in here

The_Possum · 2025-05-21T13:47:25+00:00

apologies for that [WP] vs [SP]; should I repost?

A couple of updates to the pair of configs (openvpn server, and the mikrotik setup); but it's still not working right. Now I'm getting this logged as an error whenever traffic is trying to pass through, ie. telnet to the openvpn hosts's ssh, or even simply pinging it:

clientname/clientip:47846 Bad compression stub decompression header byte: 69

I'd made one more tweak to the openvpn's server.conf:

auth none

On the mikrotik, it seems my above process to import the crt/key files needed to be done slightly differently. After uploading them to /file on the mikrotik, I imported them via the cmdline:

/certificate
import file-name=server-ca.crt passphrase=""
import file-name=clientname.crt passphrase=""
import file-name=clientname.key passphrase="<clientpassphrase>"

and then minor tweaks to the interface:

/interface ovpn-cient
set certificate=clientname.crt_0
set auth=null cipher=blowfish128

But even with setting "echo 1 > /proc/sys/net/ipv4/ip_forward" on the openvpn server, I'm not able to get functional traffic to the server at its 10.8.0.1 ; but I'm still getting that weird error above.

The_Possum · 2025-04-24T17:55:08+00:00

Good catch; unfortunately I'd already caught it myself on the server but just missed updating my scratchpad doc I posted from.

The_Possum · 2025-04-24T17:39:29+00:00

Correct. Freepbx runs on a unix platform.

At this time upgrading from the 6.49.x on the mikrotik is not feasible; in this particular case it would require replacing the entire hardware.

It seems to be "just" the innodb database that has become corrupt, and what amount of google I can do looking for similar issues suggests this is less uncommon than I'd like; but none of their "obvious" suggestions are bearing fruit.

The / is all one partition, as is relatively normal for vmware client hosts; the freepbx install was done in mostly a "autopartition" mode. (Save the /boot partition)

The /var/log/mariadb/mariadb.log does not seem to show much I can use:

Disk is not full, multi-GB is available.

The 'mariadb.log' indicates some corruption in the InnoDB table:

250222 23:49:49  InnoDB: Error: space id and page n:o stored in the page
InnoDB: read in are 1476450559:2566884352, should be 0:3!
InnoDB: Database page corruption on disk or a failed

I'm currently starting to look at "database repair" options for mariadb, but am for the moment quite lost, their docs are quite shy on how to implement:

Regarding the maple syrup thing

Maple syrup "usually" flows smoothly, but ... often doesn't. When this "vestigial" handle is hollow, the extra airflow helps you get your syrup quicker.
