Linux activated firewall, blocked my ssh access

[roriscrave]

Hello, i installed the firewall on my linux and now i can't access via ssh, any way to reverse this situation?

used

sudo apt-get install ufw

when I try to access via ssh it appears: "Connection time out"
I believe that port 22 was blocked

If you are on OVH try enter with Recue Mode and disable it, or contact support.

There's some information here:

How To Configure Firewall with UFW on Ubuntu Linux

The firewall prevents unwanted networks inside a system. In this post, we are going to learn how to configure the firewall with UFW on Ubuntu Linux.

www.ubuntupit.com

This (taken from that page) should make port 22 (SSH's well-known port) available again:

sudo ufw allow ssh

Note that it makes the port available to anyone, so you're back to being very insecure

This looks close to what you need (taken from the same source):

sudo ufw allow from 192.168.0.1 to any port 22

... except of course change "192.168.0.1" to the address you want to connect from.
If it's the same system, try the loopback address (127.0.0.1)

Note that the Firewall commands are relatively simple. I suggest you find a full list and play around with them.
These two links look quite good. I just looked at the first one that came up from the search for the reply above, but if I had ufw installed I think I'd start with linoxide.com for commands, maybe the second to see the GUI screen caps.

Did you try listing the firewall rules, and if necessary setting rules to allow access to the SSH port?
