Debian 8 questions

I have installed Debian 8 and everything is fine.But I could not find any firewall as in Ubuntu.Should I install ufw or is there any default firewall enabled for debian ?Thanks in advance.

 

Well, there is a firewall in all modern Linux. It's called "Netfilter" You also have Iptables installed.

However, there is no UFW or GUFW installed. But you can install them if you want. Then do (as in Ubuntu):

Code:

ufw enable

Then:

Code:

systemctl enable ufw

 

Are iptables and netfilter running or do I have to enable them?

 

They're running. To view it's rules, just do:

iptables -L -v

 

Thank you

 

You're welcome

 

Is there a graphical software center like in Ubuntu or Mint?

 

No.... You can just use the package manager to install most things from the repos, or if you want, you can install the package "software-center" from the repos and then you'll have it.

 

Package came preinstalled.I installed debian today.Software-center is not available for jessie it is available for wheezy.

 

Closest you can get is Synaptic, which is a reasonable GUI package manager front end. https://wiki.debian.org/Synaptic

 

Yeap, Synaptic is quite handy.
If you use it to install a handful of programs how will those be updated/upgraded with time? Will the OS do it or do you have to do it manually?

 

Ok, sorry and thanks for correcting me guys, I was using Synaptic myself, but Googled and thought you could install "software-center" in Jessie... When I last installed Debian a few weeks ago from the 8.2 netinstall ISO, I'm pretty sure I didn't get software-center at all, so it must be default in Wheezy(?) I did a Cinnamon install...

 

I've become a fan of iptables-persistent and just (gradually) learning iptables
