Seems to work well on lupu 528.005 it tells the name of
my ISP four instances but I have no idea what they tell.

Could mean my ISP wants to have 4 ports open?
Maybe one are to ping me to see if me still have computer running?
But all the others+ No indication that they go outside of ISP
no mention of any IP only teh coded name of my ISP

Even now when I have the browser looking here in thread
two tabs open to Murga forum it still only give this

COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
cupsd 6211 root 6u IPv4 5654 0t0 TCP localhost:631 (LISTEN)
cupsd 6211 root 8u IPv4 5657 0t0 UDP *:631

okay I test the original now and not the final code I get back
nope that gave same result. If I clich the network icon in tray it says

Murga-linux.com
208.109.22.214/‎

when I google so the icon gives more information
about such but I know the other program is for to see
if some program own things still after not being on net ?

Hi musher0.
I have set up my Firefox to delete all history and all cookies when closing FF, see pic, and I have made it a habit to close the FF after browsing a site - like this one - where I log in, or after having made a lot of queries or browsed a lot of sites about a spesific topic.
I guess your browser activity level will decide if it is suitable for you.

I placed a question in a thread some time ago, whether Google was activated if you only write part of the name of a site you want to browse, and the answer was YES, if Google is set as your default search engine.

@tallboy:
I use opera, and I do very much the same as you suggest above to keep my connections "clean".

@nooby:
Actually, nooby, that's exactly my initial question.

As you can see from the attached illustration, I have only one tab open in
opera (this thread on the Puppy forum), but I have 8 listings in lsof and as
many in htop.

You may think that I am very advanced, but I'm self-taught in computing,
probably like yourself, so there are many questions I do not have an
answer to. This is one of them.

So... Why 8 connections for 1 web site? What's going on here?

Maybe somebody knowledgeable in Internet connections could shed
some light on this? Thanks in advance.

Best regards.

The items below, which are in some browsers, will connect to the internet even though you’ve just opened a browser window …

Live Bookmarks “RSS feed” , (e.g. UK Firefox comes with BBC news RSS feed in bookmarks which automatically downloads today's headline stories ).

Google Safe Browsing , ( built in to browser, on by default ), or similar service like Yandex to protect you from malware phishing sites.

WOT (a browser add-on) … http://en.wikipedia.org/wiki/WOT_Services connects to the internet as soon as you open a browser window.

If you actually visit a webpage then that page can connect you to other resources , say YouTube because here is an embedded YouTube video on the webpage.

The browser addons NoScript AdBlockPlus and Ghostery block unwanted stuff when browsing via FireFox, (the latter two are available for Opera).

Thanks Barkin what you write there most likely do explain
why so many connections are active. We need to find out
what one can do to get aware of when something bad is connected?

Take this things named "Key Loggers" that is really bad things.
They lay there on your computer and get activated as soon
as you start up and they record every key press and send these
on demand to the person that wants to be able to log in to your Bank?

Then we have those that intercept and redirect to faked sites.
such looks like the real site they have duplicated real sites
but have their own code on it so work as a in between
and can use your input for to move money from your bank
to their bank while you think you move your money to something
you buy or within your own bank.

Would be cool to have some pet or sfs that can warn about such activity
and stop it instantly obviosly.

Thanks Barkin for the references.

Installing the AdBlockPlus extension in opera instantly reduced the number
of connections. But now I have 1 listing less in lsof than I have tabs in
opera...

All this is still a bit mysterious...

nooby said:

It's called "phishing", and opera has a parameter you can activate to detect
that (I don't know if the Mozilla browsers have the same. Probably.)

BFN.

Hello, again, all.

I know that using a good hosts file can increase security.
For ex., the MVPS HOSTS file from
http://winhelp2002.mvps.org/hosts.htm

How about the hosts.allow and hosts.deny file in /etc?
Can they also be used to increase security? If so, how?

Thanks in advance.

The MVPS HOSTS file performs the same function as AdBlockPlus, however AdBlockPlus has the advantage that its blacklist ("filter subscripions") is automatically updated weekly.

NB: Having a very large hosts file can slow down browsing.

NoScript uses a white-list rather than a blacklist: no script (geddit), runs without your consent, a whitelist is quicker and safer than a blacklist. IIRC NoScript is only available for Firefox & seamonkey.
