Hallo derbert,

bin auch über das Problem - und dabei über deinen Beitrag - gestolpert. Zumindest in meinem Fall konnte ich feststellen, warum die automatischen Regeln allein nicht reichen. Diese umfassen nur ausgewählte ICMPv6-Typen. In meinem Fall war zusätzlich eine Regel notwendig, welche ICMPv6 Typ 130 (Multicast listener query) mit Ziel ff02::1 beinhaltet. Wozu das Paket benötigt wird, würde mich auch interessieren (DS-Lite?)...

Beste Grüße

Thanks Patrick, my fault.
I was searching for (permanently) changes to the ssh keys to generate when i stumbled upon this question, so i had a "key-bias" in mind...

Hi Scenic3050,

you can configure all you need with the webgui.

Keys:
System \ Access \ Users \ [ Username ] \ Authorized keys

No password:
System \ Settings \ Administration \ Secure Shell \ Authentication Method

Nevertheless, "sshd_config" is located at "/usr/local/etc/ssh/"

Cheers

OPNsense 23.7.12_5

When I use the search field in "Firewall : Log Files : Plain View" it seems I only get events displayed if they fill up a hole page (at least 20).

To reproduce I choose a known target - e. g. "142.250.185.195" (www.google.de) - to search for and get a lot of events.

And "142.250.185.195,60" - I know, there is at least one event, but I only get:

I don't expect this as an intended behavior, how can I find single or seldom events?

Thanks for any hint!

I struggled with that yesterday and it turned out, that my VDSL provider doesn't use VLAN.
So be sure you really need it.

That solved the problem with console login and su for me.

Thanks a lot!

I just did another test. I reset the device to factory defaults. Logon at the console works as expected.
Then I only activated the option "Disable integrated authentication" and I no longer able to login at the console.

Is this an intended behavior?

If I have enabled 2FA, local database and deactivated "Disable integrated authentication" I can login at the console with the user with and without OTP and also with root and the password.

With the activated option "Disable integrated authentication" it is not possible to login at the console and not possible to do su in ssh.
OPNsense version 23.1.11_2

Context:
I have configured 2FA with TOTP and set up a user (not root) with an OTP seed. This user is a member of the group "admins". Additionally I configured SSH public keys for that user. Login to the webgui with 2FA and SSH-login with public key works well. The user 'root' doesn't have either an OTP seed or a public key.

As fallback in case of problems with 2FA, I wanted to login per SSH with key or console. But as soon as I activate "Disable integrated authentication" I can not login to the console and I can not su to root in SSH.

Thanks for any hint!

We use a group of restricted users to gain access to the webgui with the following assigned privileges.

GUI    Dashboard (all)
GUI    Diagnostics: Logs: DHCP
GUI    Diagnostics: Logs: Firewall: Live View
GUI    Services: Unbound DNS: Log File
GUI    Status: DHCP leases

In OPNsense version 22.7.2 (2 devices) those users see running services in the dashboard. In version 23.1.11 (11 devices) those users see an empty service widget. Services will be shown in the widget, if we additional assign the privilege "GUI Status: Services". But then they are able to stop or start services, which isn't intended.

Any idea how to list running services for restricted users without the option to start or stop any services?

Thanks for any hint!

IDS is off for all boxes. I try to keep configuration of all running boxes the same way, that is why i stumbled about this.

The status page changed with 22.7. release. The former i-button is replaced by a checkbox.

Yes, there is a DHCP server at all ix0 interfaces, but onle some are in the promiscuous mode.
