pfsense 2.6.0 sshguard @ web gui bug/crash

@violetdragon I have noticed that PHP is using some RAM and some CPU when the Gui works.

@violetdragon Just thought i'd mention this, after having another look it's something on the home page that is causing the issue, when the home page does not load if i go to any of the tab it loads them but not the home page.
(Edit)
The problem is the Disks Widget, when the Disk widget is on the home page the problem appears home page does not load when removed off the home page problem disappears
-
Huh, that's interesting. The disks widget is there by default on on 2.6 installs so I would have expected many more reports of similar behaviour.
Do you have an unusual disk setup?
Is there anything logged in the nginx or system logs when this happens?Steve
-
@stephenw10 Hi, only disk setup I have are 2x 60GB Solid State Drives in a mirror, nope nothing in the logs, would it be possible to post a video so you can see it? It's strange ain't it.
-
Sure post a video, or link to it. I'd like to see it.
I have systems with dual ZFS disks in a mirror but they are smaller.

Is this a gmirror setup that's been upgraded over time or a ZFS mirror?
I have several ZFS mirrors and the disk widget works fine there but I don't think I have any gmirror setups on 2.6 currently.

No problems on the test box I use for this:

Probably not related, but :

Who is accessing what from where ?
Why is a LAN based client using "violetdragon.ddns.net" (the WAN IP ?? )- why not using the LAN IP of pfSense host name, which is 192.168.1.1 ?
Or is your pfsense really called "violetdragon" and your domain set to "ddns.net" ? So "violetdragon.ddns.net" is 192.168.1.1 (looks very wrong to me).No "help me" PM's please. Use the forum, the community will thank you.
Edit : and where are the logs ?? -
It's unusual but it should work fine that way. The disks widget shouldn't care.
-
Sure thing.
It looked to me as if the request came from the 'outside' which means he opened up the GUI to the outside world. And that opens up a can of worms. -
@gertjan If you look at the logs carefully, you will see that the 1.9 IP is my workstation, violetdragon.ddns.net was the DDNS Hostname of the firewall and I was internally wrapping it inside meaning, I was using the DDNS Hostname with DNS Resolver it is not unusual to do, I moved to two Static IPs for Ha on my WAN so now i am using a proper FQDN with DNS Resolver & Haproxy with SSL Offloading for Lets Encrypts for both Internal Services and External Services, I guess your not familiar with this kind of setup, and yes I have moved the IP of the Firewall from 1.1 this is what you do in the CCNA world. Web Gui is not publicly exposed I am not that dumb to publicly expose the Web Gui same with SSH on everything, for External use I use my FQDN and OpenVPN/IPsec for offsite Servers.

@jimp Hi, it is a ZFS Mirror.
-
Mmm, not seeing any issues on systems with ZFS mirrors here.
Hopefully the video should clarify things.Steve
-
@stephenw10 I will get the video to you in a few hours, I have had a busy weekend with it being bank holiday. Sorry for the delays.
-
No worries, I'm glad you were able to narrow down the cause this far already.
-
@stephenw10 Hi, Just to report back. Even after removing the Disk Widget the problem is still there cannot access the web gui at all then it starts working but can access different tabs. This is weird.
-
@stephenw10 Hi, Here is the Video, I had to put it on one of my Servers, Hopefully you will be able to play it. This is from one of my Firewalls in a different location, I have another with the same issue as well. (https://cloud.violetdragonscloudnetwork.co.uk/s/iCKFFgmqQ8jLQ5a)

What happens when you use the 'admin' user ?
Jack is fine, but that's probably not an 'admin'.
Dome info collected by the dashboard GUI page need 'admin' rights.Why creating a user like Jack ? pfSense is a router firewall, not some file server.
-
@gertjan Security, admin is a easy username to guess. Admin user does the exact same. But I have a ton of PHP-FPM processes when this happens. I've also triggered the problem by attempting brute-forces via SSH. I have va feeling that maybe something is going on.

Yeah, but who cares ?
Normally, the GUI should only be accessible from the LAN interface.
The other LAN ( OPT1 OPT2 OPT3 ) interfaces are meant to be used for you local network.
This allows you to even completely disconnect the LAN interface when you don't need the GUI access. That what security is.Easy user names and passwords are a thing on a public network.
Your LAN is not a public network.I've changed a user called '001' so it has admin privilges, like this :
Now I can login with '001' and the dashboard shows up in half a second.
What happens when you remove all or most of the the widgets ?
Login again to try again.
