I am about to configure firewall with UFW. I am logged in over SSH so I don't know if the terminal will be locked out as soon as I do:
sudo ufw default deny incoming
If so, how can I deny all incoming (lock the whole thing down) except SSH and do it all in the same command?
iptables ufw

In my experience, despite the warnings, enabling UFW does not lock out the current session. By default, UFW will block all incoming. To allow SSH, use:
sudo ufw allow OpenSSH
You can also use the limit
option (note that port 22 is the default SSH port):
sudo ufw limit 22/tcp
To enable UFW use:
sudo ufw enable
1
You can also use theat
command to issue a "sudo disable UFW" at +5 minutes, so if you do get locked out, you can wait 5 minutes, and be allowed back in ;)

In my experience, despite the warnings, enabling UFW does not lock out the current session. By default, UFW will block all incoming. To allow SSH, use:
sudo ufw allow OpenSSH
You can also use the limit
option (note that port 22 is the default SSH port):
sudo ufw limit 22/tcp
To enable UFW use:
sudo ufw enable

You can also use theat
