[SOLVED] Turn Firewall off

DaveAmour · 09-30-2020, 11:41 PM

I was able to SSH to my system and after tinkering with the firewall I can no longer do so

I want to turn my firewall off to confirm this

How do I do that?

That depends on the firewall your system is using. In case it's ufw, I believe the answer is ufw disable. There is a nice page on ufw on the Ubuntu help site.

The Debian wiki contains a (complete? Probably not) list of firewalls. You could also tell us roughly what tinkering you did.

Ok thanks

Apologies in advance as I have only been using Linux a few days.

So the next question is how do I know which firewall I am using?

What were you "tinkering with"?

I tried 2 Apps. One just called Firewall and one called Firewall Builder. I guessed that these were just user interfaces to the same default firewall but I really don't know. Are these separate firewalls? Do I know have multiple firewalls running? I'll see if I can uninstall them.

OK, post the output of 'iptables-save'.

DaveAmour · 10-01-2020, 08:31 AM

Sorry not sure what iptables-save means?

I tried entering that in a terminal but it said command not found

I tried iptables-save and iptables on its own

I also tried after entering su and my root password

The su command alone doesn't give you the full root environment. Use su - (with a dash) instead.

To ask the same question in different forums risks people wasting their time providing an answer that was already given.

I am guilty of doing that as well, but it should be avoided.

Try the command as root

iptables -F

DaveAmour · 10-01-2020, 09:10 AM

Ok thanks Thanks berndbausch I shall refrain from doing so but will see these through and use them to decide which is the better forum.

michaelk - still command not found

DaveAmour · 10-01-2020, 09:16 AM

Ok SSH and ping working now!

What is the protocol for closing questions here?

It's best to ask in the place most likely to get an answer, but the important thing is to provide a link - on both ends - so that people can check existing responses before answering.

It's not just a waste of time for responders, but it means the OP is less likely to get the same advice/questions twice.

Ok thanks boughtonp
