24.1 Legacy Series / Re: 24.1 - DHCP server moves to KEA - implications?

« on: February 04, 2024, 04:23:28 am »

I tried using kea without luck so far... Even though I disabled the ISC server on my vlan 630, stopped and started ISC to make sure it frees up the listening on port 67 on 192.168.63.1 but kea still complains it's unable to start properly

Code: [Select]

WARN [kea-dhcp4.dhcpsrv.0x83359d000] DHCPSRV_OPEN_SOCKET_FAIL failed to open socket: Failed to open socket on interface ix1_vlan630, reason: failed to bind fallback socket to address 192.168.63.1, port 67, reason: Address already in use - is another DHCP server running?

Checking netstat, I see *:67 so I guess ISC is listening on *:67 and prevents kea from running side-by-side.

Still trying to see if there is a way around this...

I have multiple vlans and was getting the same type of error messages. What worked for me was stopping the ISC DHCP service and then starting the KEA DHCP service. Before shutting down ISC DHCP service (clicking the red square button) I only disabled the particular VLAN interface within ISC DHCP that I wanted to test in KEA DHCP. I thought that was enough but it wasn't because ISC DHCP was still running and binding to the VLAN interface eventhough I had disabled listening on it in ISC DHCP.

22.1 Legacy Series / [SOLVED]: openssl public key verification = Verification Failure

« on: February 23, 2022, 12:08:19 am »

Thanks to Franco pointing out what I was missing, I was able to correct my steps and get back on track with successful results. Here were the command line steps I used to verify the download by using sha256 and openssl.

1.  Download all files directly (my download folder is Downloads). In my case, I downloaded the files from https://mirrors.nycbug.org/pub/opnsense/releases/mirror/ .  The README file contains the public key (one of a few that I checked from different sources, and they all matched): https://mirrors.nycbug.org/pub/opnsense/releases/mirror/README

2.  The written instructions for verifying the image file are found at https://docs.opnsense.org/manual/install.html

3. Then from within the terminal enter the following commands in the sequence listed.

anthony@opensusebox:~> cd Downloads

anthony@opensusebox:~/Downloads> ls
OPNsense-22.1-OpenSSL-checksums-amd64.sha256

Verified OK
anthony@opensusebox:~/Downloads>

Done. Then off to creating the bootable USB according to instructions at https://opnsense.org/users/get-started/

Thank you Franco. I mis-interpreted the instructions and didn't apply the converson step. I appreciate you clarifying this important piece of the puzzle. I'll attempt this again later (stepping out now) and report back here...

Best regards

22.1 Legacy Series / [SOLVED]: openssl public key verification = Verification Failure

« on: February 22, 2022, 08:28:10 pm »

Hello

I am able to perform sha256sum on the downloaded bz2-zipped image file and it checks out ok (see below), however when I use the openssl public key verification method it fails the check. I verified the public key I downloaded from a few sources were all the same, so with that I can at least have some level of confidence the key is legit:
-----BEGIN PUBLIC KEY-----

YHWiWxZTN13z4mPqA4uebakCAwEAAQ==
-----END PUBLIC KEY-----

This verification failure happens no mater if I download from a server in the US or Netherlands (haven't tried others). When I attempt to perform the public key verification of the downloaded image I get "Verification Failure". When it fails a check, the instructions at https://docs.opnsense.org/manual/install.html state "...you may have made an error using the commands, or the image has been compromised."

The details for these instructions state the following:
"Once you have downloaded all the required files and a copy of the public key, and verified that the public key matches the public key from the alternate sources listed above, you can be relatively certain that the key has not been tampered with. To verify the downloaded image, run the following commands (substituting the names in brackets for the files you downloaded):

openssl base64 -d -in <filename>.sig -out /tmp/image.sig

openssl dgst -sha256 -verify <key>.pub -signature /tmp/image.sig <image>.img.bz2

Make sure to change the “img” to “iso” in the second line if you downloaded a different installer type.

If the output of the second command is “Verified OK”, your image was verified successfully, and you can install it. If it has any other output, you may have made an error using the commands, or the image may have been compromised."


Here are the sequence of commands as I entered them in the terminal:

anthony@opensusebox:~/Downloads> ls
OPNsense-22.1-OpenSSL-checksums-amd64.sha256      OPNsense-22.1-OpenSSL-vga-amd64.img.bz2      OPNsense-22.1.pub     
OPNsense-22.1-OpenSSL-checksums-amd64.sha256.sig  OPNsense-22.1-OpenSSL-vga-amd64.img.bz2.sig  OPNsense-22.1.pub.sig

anthony@opensusebox:~/Downloads> sha256sum OPNsense-22.1-OpenSSL-vga-amd64.img.bz2
f791e9024888f5f668175a78cbbcd9eb96b36ba523f38d00cad9dd4d64243b4f  OPNsense-22.1-OpenSSL-vga-amd64.img.bz2

anthony@opensusebox:~/Downloads> openssl dgst -sha256 -verify OPNsense-22.1.pub -signature OPNsense-22.1-OpenSSL-vga-amd64.img.bz2.sig OPNsense-22.1-OpenSSL-vga-amd64.img.bz2
Verification Failure

anthony@opensusebox:~/Downloads>

Can anyone point out any mistakes I might have made in the commands above? Is there anything to be concerned about when sha256sum passes, but the public key method does not?

Thank you if you can help.


Regards
Anthony

19.1 Legacy Series / Resolved: In OPNsense 19.1 can't find growl notifications

« on: March 25, 2019, 01:38:07 am »

Did some research on the web because I couldn't find out any sooner from searching this forum. Basically Growl notifications got replaced with Monit. There, resolved.

from https://github.com/opnsense/core/issues/2408

Hi @lopsch,

The current notification framework is scheduled for a full removal in 18.7. We already imported Monit into the core package for this reason. I don't see this code going anywhere because of it. Ok?

Cheers,
Franco

19.1 Legacy Series / In OPNsense 19.1 can't find growl notifications

« on: March 24, 2019, 11:19:17 pm »

In previous OPNsense versions I had setup growl notifications but in 19.1 I can't find the configuration setup in the web GUI. Has Growl been eliminated? Or am I not seeing it?

Hi Franco

Thank you very much for the instruction, and quick reply. I'll do that next.

19.1 Legacy Series / [SOLVED] Edited changes to suricata.yaml do not hold in OPNsense 19.1.4-amd64

« on: March 19, 2019, 03:07:12 am »

I am able to make changes to paramaters in suricata.yaml , and the file appears to save properly with the edits (file size changes after initially being saved with the edits), but then the file reverts back to the original form and size again (as if never edited) as soon as suricata is enabled again. I tried many variations of trying to edit this file: making the edits on the desktop, then using scp to transfer to the OPNSense router; making the edits from within the OPNSense shell (ssh) using vi. The edits made to this file just don't stick. Anyone else having this problem? Anyone know what the cause it and how to fix it?
