Ultimate Edition Forum

After much needed help w/ printer & file-sharing via LAN, which is now resolved (thanks 'pch.shot')...

Can anyone now help with the proper & effective configuration of the Ultimate Edition's (v/ 3.0) on-board software firewall, for protection... WHILE effectively maintaining 'fluid' networking (printer & file-sharing) via LAN involving other MS OS (WIN 7 64-Bit & WIN XP 32-Bit) computers?

Thank you so much in advance!

Maybe place a link to your network places on your desktop for easy access.
Make sure you have sharing on your ms boxes(the little hand under the drive).
You may have to go to network setup wizard in ms and then re-boot for Ultimate to see your ms network.

Make sure that the ms boxes have strong firewall and anti-virus software on them.There are lots of good free ones out there. Due to the way Linux is designed(there is no registry-no central place of attack) I doubt you will have issues there. Explorer is always running so viruses can travel to other ms computers on your network. I wouldn't worry about the boxes running Linux too much. ms on the other hand I would be very concerned about.

Thank you, both ("Blackwolf" & "pch.shot") very much for you input.
However, I couldn't get any of it to work, even "Firestarter!"

I FINALLY found the terminal script (formula) from back when I was trying-out Mint 11, and IT WORKS LIKE A CHARM, in Ultimate Edition 3.0 as well, for both 'wifi' and hard-wired Internet connections. And you folks may well wish to take note of this one, for both 'file-sharing' and 'printer acquisition,' via a LAN. (I, BTW, didn't figure it out - it came from "altair4" in the Mint Forum. He [or she] figured it out.)

First, "Enable" the Firewal and then set the Firewall's "Incoming" to "Deny;" and set the "Outgoing" to "Allow." At least, that's how I did it!

Then, here is the terminal formula for resolving the on-board Firewall issues relative to 'file-sharing' and 'printer acquisition,' via a LAN...

Give this a shot:

[1] Allow samba access
Code: Select all
sudo ufw allow Samba

[2] Allow CUPS access
Code: Select all
sudo ufw allow CUPS

EDIT: The capitalization of "Samba" and "CUPS" is important. To get a list of all these preset firewall rules and how they are spelled:
Code: Select all
sudo ufw app list

[3] Fix an oversight in the default firewall configuration

Edit a file as root:
Code: Select all
gksu gedit /etc/default/ufw

And change this line:
# extra connection tracking modules to load
IPT_MODULES="nf_conntrack_ftp nf_nat_ftp nf_conntrack_irc nf_nat_irc"

To this:
# extra connection tracking modules to load
IPT_MODULES="nf_conntrack_ftp nf_nat_ftp nf_conntrack_irc nf_nat_irc nf_conntrack_netbios_ns"

Hallelujah!!!

I'll leave this up for a few days for reference and then close it out - SOLVED. OR, if the Administrators want me to mark it SOLVED asap, I'll of course comply.

Once again, thank you ALL so very much for your help!
