11.2 Users. Check your Firewall

English Network/Internet
1

**We have reason to ask this of you following some strange firewall behaviour - But don’t panic
**
If you use openSUSE 11.2 and you think:

  1. Your Firewall should be running
  2. You are not sure but think it should be

Please check and report back here.

This is how to check:

  • Go to Yast > Security and Users > Firewall

This is how it should look:

Is it OK ?
I installed a fresh openSuse 11.2 before a week or so.
I enabled it now and clicked the automatic starting.

Is there anything else that I should check? thx :slight_smile:

You say you enabled it? Does that mean it wasn’t when you checked.?

Checking with YaST(ncurses) seems to indicate it is started, ncurses does not
explicitly state this. Also “system services” shows that SuSEfirewall_XYZ
are enabled and running. iptables -l -n indicates only the desired
ports/networks are allowed.

Obviously thats iptables -L -n. Bad fingers.

Indeed - the firewall wasn’t enabled automatically. I was “exposed” until I read this thread.

8

It should be.
Thanks for reporting;)

2 machines: one Gnome 11.1, one KDE 11.2, both up and running OK

FYI of others, here’s a quick check code:

su -c 'rcSuSEfirewall2 status'

which should return this if all is OK:

Checking the status of SuSEfirewall2  running

3 machines: all run KDE 4.3.5 and openSUSE 11.2, everything OK. :stuck_out_tongue:

11

No problem! Would you like me to add details about my computer? (if so, please write the commands cuz I’m not familiar enough with linux)

12

It’s fine that you reported, that’s all we need.

13

I had mine on and working yesturday, but today I just checked and it was shut off! I am always protected anyways because I have a hardware firewall on all the time.

14

I have a hardware firewall on all the time.
Yes, me too. I think that’s probably true for many these days.
Thanks though.

On what PC hardware and version of the system (x86 or x86_64) do you see
that???

firewall up and running

17

As noted on 3 of our 5 PCs (running openSUSE-11.2), the firewall was UP. On two PCs the firewall was down.

One one PC I correlated the firewall being down to the same day as a massive rpm update, where one of the packages being updated was Network-Manager. Possibly relevant.

On the other PC (a laptop) where the firewall was down I did not bother checking why. I had been messing a LOT with the wireless, and I assume something I did there brought down the firewall.

Hi
I wonder if the ones that have updated and not rebooted have the issue?

Mine is up an running on the PC but on the laptop some time ago it was down after an update. Weird.

I am assuming mine has been turned off at some point without my
knowledge because running command:‘SuSEfirewall2 status’ (in a root
console) returned no info.
I then ran 'SuSEfirewall2 start" and checked the status again and
“iptables filter” results appeared. Before applying the start command I
checked the yast2 service modules and both firewall services were running.

I set ‘SuSEfirewall2 basic’ as the running mode. Is this OK for a home
desktop system requiring only basic internet browsing and email client?

Cheers
