PostPosted: Sun 08 Dec 2013, 08:08    Post subject:  Peasy Firewall Monitor  

Update: Version 1.5 now works in 6-series Puppies and uses the original, reliable Linux Firewall. This version is backwards-compatible with the 4-series, including the tray applet.

Update: Version 1.6 can build the firewall for a trusted LAN. This lets you share services with other hosts on your local network while blocking any external traffic. For example: you can access a networked printer that uses some unknown port, or you can run a SAMBA server that client computers can see through the firewall.

If you really, really think that you need a firewall, this is the most flexible setup. Running a firewall, then opening individual ports is stupid.

Update: Consider this situation: your laptop is connected to your home network using Trusted LAN. You go outside and connect to a public WiFi hotspot with a different network. Now you do NOT want to be using Trusted LAN. In fact, you should have ZERO open ports! PFM v1.9 has a button that restores the default maximum firewall.

If you take your laptop to a friend's house and join their network to share files, you must re-run Trusted LAN. Do it AFTER you have received an IP address on the new network.

----------------------------

It isn't pretty, but it will tell you exactly what your firewall is doing. A must-have for diagnosing problems with file/print sharing.

Run it from the Network menu or from an optional tray applet.

For users who are afraid that their firewall might spontaneously turn itself off, and want a tray icon to inform them when it happens, and are willing to sacrifice the extra CPU cycles to run it, go here.

The 64bit of PFM version is here.

Good simple way to control firewall.
Thanks!

Works in Slacko 5.6.3 test version made with Woof-CE.

One really good, needed feature, I am not seeing.
The icon, on the task bar, does not change, indicating the state of the firewall.

That is the one feature of Firewallstate that I like.
A quick look at icon tells you if firewall is on or off.
The icon changes with state of firewall.

That's not a feature of the applet. This is meant primarily as a diagnostic tool where you can see the explicit words ON or OFF.

Here is the problem with the icon. I have participated in numerous frustrating episodes where people could not get file/print sharing to work because the firewall was on when they were convinced that it was off. Either the icon was not working or they were interpreting it wrong.

Sometimes, a word is worth a thousand pictures.

PostPosted: Tue 10 Dec 2013, 01:15    Post subject: Advancement in Firewall Management for the local PC  

This is a great addition to Puppyland. I had hinted at this before. Every PUP distro benefits from management like this.

Other features, should there be a future enhanced version is a firewall monitor option to show one of the following
  • ports open/blocked
  • a ports changer/configurator
This tool could be an addition or replacement to the current confusing tool making it easy for new user (any user) to understand and follow.

Question
    Is this aimed for 32bit, 64bit or both?
Hope this helps

I have posted v1.4 that shows a list of open ports when the firewall is up. Please test and report.

Here is the more important issue. Why does Puppy make it so easy for beginners to turn on a firewall when many of them (those on a local network behind a router) really don't need it?

Have you tested it yourself on a 64-bit machine?

chmod +x /root/Downloads/peasyfwmon-1.4/root/Startup/peasyfwmon_tray
/root/Downloads/peasyfwmon-1.4/root/Startup/peasyfwmon_tray

Seems to work with Puppy-4
GNU C Library stable release version 2.6.1, by Roland McGrath et al.

May I ask where the binary is from ?

With good reason. I want the tray applet to be optional. This is primarily a diagnostic tool.

Installed and runs fine in xprecise 2.2 (precise 5.6.1 based), LxPup 13.10 (slacko 5.6 based), and in Carolite 1.1 (Racy 5.2.2 based). Nice to have quick confirmation of port status without having to scan separately.

rcrsn51 as you know by now I am not very bright Smile

Do you tell us that the icon that shift in the tray
does not show reality. While your monitor
is a reliable such indicator. Then I should get that program.

I'm not making that claim. I am just providing an alternate diagnostic tool that may be useful in some situations.

Useful app. I have installed it on ThinSlacko 5.3.3t (2012 version) and it works perfectly.

I like the way you can choose to add the peasy app icon to the tray and also remove it when desired.

If I had any suggestion it would be that due to weakening eyesight I would like to see the peasymonitor icon slightly bigger and maybe rectangular. It looks good with the flames ("fire") but if it was rectangular it would also look like a "wall". (I really should put my glasses on, but without them it looks a bit like a batman icon).

(it's mostly the fact I'm viewing it on a tiny netbook screen that isn't helping my vision limitations Smile

ps: it doesnt tell me that my internet port is open, but I think I've read before that puppy doesn't tell you if port 80(?) is open. Would that be correct?

Port 80 isn't open because you are not running a web SERVER. When you run a web browser CLIENT, it temporarily opens various high-numbered ports to communicate with servers elsewhere.

There are lots of firewall icons on the web.

1. Download one and open it in mtPaint
2. Convert it to a 16x16 XPM graphic
3. Save it as mini-firewall.xpm
4. Copy it to /usr/local/lib/X11/mini-icons
5. Reboot

Thanks! I found an icon and modified it to suit. It is the one that looks like a yellow giraffe thingy. (must be something wrong with mtPaint...)
