@stephenw10 Is there a way to view the logs from the command line or to export the existing logs to a text file?

stephenw10

You can get the complete system log by running: clog /var/log/system.log > /tmp/systemlog.txt then downloading /tmp/systemlog.txt.
You can do both those things from Diag > Command Prompt in the webgui.

The default log size is 500k though, it may no longer contain that data.

@stephenw10 Interesting. The logs show that the filesystem was full! But right now it shows:

Filesystem                     Size    Used   Avail Capacity  Mounted on
/dev/ufsid/57758f7e2e26ac75     50G     42G    4.6G    90%    /

I think we're on to something. Is there a way to have the units send an email if the disk gets over a certain percentage used?

stephenw10

Not that I'm aware of. I thik Zabbix can do it if you had that configured.

What's using 42GB there though?

Usually that only happens if some package is not behaving, usually failing to rotate it's logs. I would guess it's Suricata.

I see Squid listed as an installed/re-installed package in the first post. The Squid cache can eat up a lot of disk space. The Suricata package did have an issue with log rotation not working properly, but that was fixed a few versions back. So unless you have a really old version of Suricata, its log rotation problem should not be impacting you now.

Stewart

@stephenw10

 16G    ./suricata_igb128922
 15G    ./suricata_igb252880
 31G    .

igb128922 is an http.log files that goes back to 7/13/2017.
igb252880 is http.log and alerts.log that goes back only to 5/1/2019.

Stewart

@bmeeks Yeah, I got bit by the stats log not rotating on some other units. Not sure if this is the same. The Squid cache is 8.7GB as well.

bmeeks

The Suricata log rotation fix was this year I believe, but I don't remember precisely when. One aggravation with the Suricata binary is that not all of the log output options have built-in size limits. So I have to use a separate outside process to try and trim the files. What was happening is that Suricata would continue to write to the old file handle and thus the old file would continue to grow even though a new one was started.

stephenw10

That probably never made a 2.3.X package though....

Make sure you set a total log directory size limit as well as the individual log sizes.

Steve

bmeeks

Yeah, that fix was definitely for pfSense-2.4.x.

Stewart

I've updated to 2.4.4-p3 but the available packages page is blank:

stephenw10

Try running pkg update see what error it gives.

EDIT: WAN is up. I'm connecting out through the unit right now.

stephenw10

Can the firewall itself connect out? Ping? DNS lookup?

If you're policy routing it may have lost it's default route coming from 2.3.X.

Make sure you have a default gateway set in System > Routing > Gateways rather than set to 'automatic' there.

Steve

Stewart

Using the force command fixed it, though.

stephenw10

Ah, interesting. And it sees packages now?

Stewart

Yes. So far so good. I don't know why it ran out of space while in service but after taking it offline suddenly there is 4.6GB free. Certainly need to clear it out but where did that other space run off to? I wonder...

It would look that way to me at first glance.
