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

used
Lua:
sudo apt-get install ufw
when I try to access via ssh it appears: "Connection time out"
I believe that port 22 was blocked
 
There's some information here:

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

 
If you are on OVH try enter with Recue Mode and disable it, or contact support.
I'm following this tutorial:

but i have doubt in this part, when mount a partition (he used sdb1):

sda3, you can try mount any disc u want
 
Did you try listing the firewall rules, and if necessary setting rules to allow access to the SSH port?
on this recue mode firewall inst enabled, but if i restart game and try to enter, the firewall back to active;
what you using? OVH? use the OVH KMV login to enter the console and then use "ufw allow ssh"
i`m using ovh reseller, it costs 30$ :(
