Default TCP/IP port#s



The "well known" ports 1- 1024 are well documented.
If somebody would be so kind as to post a URL
which lists the high port numbers & their "general" use.

My RH FC3 box started getting probed within FIVE minutes
of appearing in the 'Net. Many of the probes are to port
numbers > 1024 and I am not familar with what "they"
are after. I might decide to setup a honey pot if I
have the time to do so.

Also is there any Open Source package which is a preconfigured honeypot?


TIA!

Hmmm, that long. Not a busy net

Trojaned systems.

Malware is being created at about 1 ever hour. Last number I saw, 20
new ones per 24 hours average.

There is not that many high ports being probed. Here are the noisy
ports I drop without logging. Count is for 13 days since my last reset.
Cable modem/system is on 24 hours a day. Only ss (22) and auth (113)
ports are not dropped.

http://www.iana.org/assignments/port-numbers might be useful.

Why play games with "them"? Use iptables and reject or drop all unsolicited
or undesired traffic.

It is via iptable LOG option that I am recording this activity.
Ignoring nefarious behavior only "encourages" more of it.
I want to make the perps pay for not being good 'Net neighbors.

So I'd still like to know what ports that are being probed
are supposed to do so I can provide some payback to those
who are playing with my doorknobs. They should not be on my
property seeing if I locked my back door.

And how do you think your are going to make them pay.
Only legal thing you can do is send logs to isp of offending ip owner.

What can the microsoft user do. New virus every hour.
It has to be caught by antivirus company, analyzed, added/tested to
database and user has to download it sometime later. Well hustle
around in 8 hours and your are 7 more viruses behind.

You better go back and read your Acceptable User Agreement put out by
your ISP. Just like the real world, you cannot go out and beat up the
person on your property.

Payback makes you one of "them". Deny it if you like, but one is a loser if
one plays loser games.

Most are from "the pacific rim" mainly mainland china. They are not
discouraged by their government. There is nothing you can do. Most of us
have already spent too much time trying to "catch" them and do something
about it.

I wish that the internet was split, theirs and ours. If they are in the US
they can be both criminally and civilly prosecuted.
