Netgate shared root with ISP? ¯\_(❞⦈)_/¯

jimp

ttyv0 is the physical video console. Nobody can login to that remotely. It can only be accessed via keyboard and monitor. Similarly, ttyu0 is a serial (uart) console and cannot be logged into remotely, only via local serial connection.

Seeing a login on ttyv0 just means the menu redrew itself. If you see it a lot, something is probably corrupted on your filesystem leading to a problem with the tty itself.

Nobody has shared root access with your ISP or anyone else. There are no backdoors.

So the logs you are seeing are like, for example?:

Aug 16 12:14:22 	syslogd 		kernel boot file is /boot/kernel/kernel
Aug 16 12:14:22 	kernel 		done.
Aug 16 12:14:23 	php-fpm 	343 	/rc.start_packages: Restarting/Starting all packages.
Aug 16 12:14:24 	login 		login on ttyv0 as root
Aug 16 12:15:34 	check_reload_status 		rc.newwanip starting igb0
Aug 16 12:15:35 	php-fpm 	343 	/rc.newwanip: rc.newwanip: Info: starting on igb0.

That is expected and not an indication some bad actor is connected to your firewall as that link shows.

Steve

Thanks Steve, but that is not what I see. Your log indicated services restarting because wan dhcp lease renewal process.
Ok, let just say there are no bad actors.

Would you please explain to me the Unexplained Phenomena, like why I see my floating firewall rules being changed, some were edited and some deleted (e.g. AmazonAWS IP Range) with log messages: "Syncing firewall, Reloading filter"?

When logging in to the GUI, you'll see this :

Logging in using a ssh client :

The IP's "192.168.1.120" and "2001:470:1f13:5c0:2::84" are both the ones from my LAN network.
Let's say : it's an inside job. It's me using a device on my LAN.

Btw : great : your ISP is helping you administrating your pfSense ?!!
What are your WAN firewall rules ? Or did you install a KVM module for them so they can remotely using a keyboard / VGA ? ( @jimp : people often omit to mention the most incredible details about their installation ) They have a OpenVPN access for remote administration ?

For me, it just an inside job. Or the (one of) the other you(s).

And what does your config history show.. example

Maybe you have something like pfBlockerNG which is automatically managing your rules? It does exactly those kinds of things.

johnpoz

I was thinking the same thing... While pfblocker is a great package, I am not a fan of anything that auto manipulates rules.. I use it really as just fancy aliases management - I have it create the aliases, and then I use those in my rules as I want.

But I would have to assume any changes to rules would be listed in the configuration history, but since I don't have pfblocker manipulating my rules, not sure how that would look in the log?

TheHowTo

What I know and experienced, pfBlockerNG only prioritizes their rules in floating rules order, but it never deleted any custom rules.

If you do not believe me, try to install pfBlockerNG, make custom rules to block AmazonAWS (hackers virtual machines) and then do a cron update.
Here is AmazonAWS’s IP range: AWS IP address ranges

And did you bother to look in your config history... Anything that changes the config should be listed there..

Config history says "Edited a firewall alias, made unkown change" However I did not login to SSH or GUI at that specific time.

It does not matter anymore because even after factory reset, everytime the hackers knew how to bypass the password protection.
I still give Netgate the benefit of doubt. Maybe there are some bugs or loopholes (e.g. superuser's backdoor) in PfSense version 2.4.5-p1.

I really wish that I can hardening PfSense with Firejail and Apparmor.

And what did it say did that that unknown change.. Post a screenshot of your config history showing these changes..

Gotcha!

TheHowTo

@stephenw10 Would you please tell Dev to fix these loophole (superuser's backdoor) and bug (openvpn over tcp) on the next PfSense version.
Thank you.

johnpoz

OMG dude - there is not a "superuser" backdoor.. And what bug in openvpn over tcp... It work it just fine. Where is the redmine link to this "bug"??

stephenw10

If you think you have found a bug (you almost certainly haven't) then you should open a redmine ticket with the details and how to replicate.

You are going to have to present some evidence though. There is no reason you can't post screenshots of your config history or system log text with your public IPs removed. That gives away nothing that you should care about.
Otherwise it just looks like you're trolling. We will have to lock the thread.

Hi all, I had similar problem with (2.4.5-p1) openvpn running over TCP specifically the client site. You need to edit your openvpn.inc file to fix this.

And where is the link to this bug report? Or even the thread discussing this issue, or what exactly did you change.

And lets be specific.. Stating there is a "bug" in openvpn tcp, as a client to to some vpn service? With site 2 site? I run tcp client to pfsense from my phone, from my pc at work over tcp and have not seen any "bugs" or issues at all.

Saying there is a "bug" doesn't help anyone nor is going to get anything fixed if there is an actual issue.

i don't intend to feed the troll, reported him for 3 post without any meaning, registered 27 minutes ago,I start collecting bets, 5$ .. he's a spammer

AKEGEC

Hi all, I am just trying to help and contribute, but why do I get aggressive and hostile treatments?
If you do not know how to edit an openvpn.inc file, then I suggest you have to wait for the next pfsense version. Don’t falsely accused someone, specially without established proof.

Anyway, my family and I believe, good acts will have good consequences, bad acts will have bad ones. You'd think by now people would understand…
that you reap what you sow.

Happy Sunday Everyone.

stephenw10

What did you have to change in the client side config file?

How did the issue present before you made that change?

I'm not aware of any OpenVPN TCP issue in 2.4.5p1, if you have found something you should open a redmine bug report: https://redmine.pfsense.org/

Steve

johnpoz

Great you want to help, then actually provide that vs just saying "you" fixed something...

Saying there is bug, and "you" fixed by editing openvpn.inc doesn't help or contribute anything.. Posting what was fixed, and how you fixed it would be information people could actually use.
