I lost access to the web GUI after an unknown change on our FW. Is there a way to roll back to a system state prior to the change from the CONSOLE?
-
I was able to copy the contents of /conf/config.xml
Now I need to see how I locked myself out and fix the config then default a restore the backup.
Where am I going to find the FW rule that locked me out? I have a similar config from another site I could copy from but don't know where to look.
-
ssh into the system, goto /config/backup. Look for the config.xml before the time you broke it... copy it over, exit to the menu and select reboot... all should be good.You could also use winscp or equiv to list and copy.
You can also use the before and after configs by comparing to find out which rule broke it.

Thank you. I do not have SSH access turned on, but I am able to get to the file via serial console, but it also appears that my root password is not working. My user that I use to log into and admin the webgui and is member of the adminstrators group works for console login.
Is there a way to boot to single user mode to reset the root password to then copy the file?
-
So I am trying to boot to single user mode and it hangs here:

If I could get to root I could restore one of the backup files by coping for backup to conf. How is the best way to reset the root passwd? Single User mode seems to be hanging when I attempt to boot to rest root password. Is there a way yo boot from a usb key with a live install image and restore one of the backups on the ssd on the ssd image?
I am assuming if I can get shell on the live instance, I could mount the ssd image but not sure the commands to do so. Please advise.
-
SO I have shell in a live OPNSense boot. I now need to be able to copy one of the backup files on the internal OPNSense ssd.
I am booted on the live image from here:
<SanDisk U3 Cruzer Micro 8.02> at scbus1 target 0 lun 0 (pass1,da0)
How do I mount the ssd located here in rw mode
<KINGSTON SMS200S3120G 60AABBF0> at scbus0 target 0 lun 0 (pass0,ada0)
so I can rollback the config to one of the backups?
Also can I reset the root password fro this session on the internal session? I could also just edit the backup config.xml and replace the hashed password for root with my know user password too if that would work.

I am in console in live session off USB.
Ran the following commands:

I have tried mounting by:
mkdir /tmp/mounted
then tried:
root@OPNsense:~ # mount /dev/ada0p2 /tmp/mounted/
mount: /dev/ada0p2: Invalid argument
Please help.... I am on the road and set to leave in 10 hours and I need to get this firewall back up...

I ended up having to use a non-root user to view trhe old config file, copy yhe text out of puTTY and then save the config.xml file. I then re-installed opnsense (where I found that I could of reset the root user password!) and did a clean install. I setup the basic nic's, logged in to the default setup then recovered the old cofnig.
This got me back up where I was abloe to compelte the setup.
Couple of learned things:
- I Lost webgui again while reconfiguration to add a second internet connection. I no longer can access the webgui AGAIN. I cannot reach from inside or from outside the network. I have never experienced this fragility before....
- I wish someone had directed me to trying to reset root by using the installer usb key
I once again need to re-gain gui access and now I am on a production network and am 2000 miles away. I am stuck with one internet interface setup without an active gateway and cannot finish failover config
I have been less than happy with the gotcha's here.
-
Can anyone provide a way from Console to regain access to the webgui after losing for a second time and complete reinstall?
-
All configs are backed up in /conf/backup.
look in there and copy a backup that worked to /conf and delete the existing config and rename the copied one config.xml, reboot and you should be back to where you were.
And don't do it again. :P
