RE; Firewall

**offgridguy** · January 31st, 2013

Regarding firewall settings using ufw here.

https://wiki.ubuntu.com/BasicSecurity/Firewall

When i get to this command and paste it into the terminal, i get invalid clause message??

Code:

sudo ufw allow out 51413/tcp sudo ufw allow out 51413/udp sudo ufw allow out 6969/tcp

I would think they need to be separate commands; either

Code:

sudo ufw allow out 51413/tcp ; sudo ufw allow out 51413/udp ; sudo ufw allow out 6969/tcp

or

Code:

sudo ufw allow out 51413/tcp 
sudo ufw allow out 51413/udp 
sudo ufw allow out 6969/tcp

You could be right, however the other commands to that point worked verbatim. perhaps the
addition of && between commands ?? Thanks for the reply, I will try your suggestion.

I edited the wiki. I think 3 separate lines was the original intent, but it did not render as such.

Edit: It is 3 separate lines in Dandertux's original forums thread.

It does work as three separate commands, thanks.

it is a small technical issue, but with bash, on the command line, ";" means to continue. So you can type it all on one line. If it did not work there was a typo.

Code:

bodhi@ubuntu~# echo "1" ; echo "2"
1
2

With that in mind, 3 separate lines on the wiki is more readable and less technical (IMO)

On the command line, && and || are logical operators, and / or

Code:

bodhi@ubuntu~# ecko "1"
zsh: command not found: ecko

bodhi@ubuntu~# ecko "1" || echo "wrong command"
zsh: command not found: ecko
wrong command

bodhi@ubuntu~# ecko "1" && echo "wrong command"
zsh: command not found: ecko
bodhi@ubuntu~#

sure I am using zsh, same thing in bash.

bohdi.zazen, thanks for the info, i am glad the wiki has been edited as well. I knew it wasn't a typo on my part as i was pasting it into the terminal.

My bad. Thanks for fixing it Doug.

And that reminds me I never replaced the photos. That was the whole reason I copied Dangertux's thread into the wiki.

Offgridguy- take some screen shots while you work on that!
