Ports 376 (NIP) and 1434 (MS-SQL-M)

[=?iso-8859-1?B?VG9taSBI5HPk?=]

I scanned my computer (Windows 2000 SP4), and found out that I have
ports 135, 376, and 1434 filtered (open).

Why are they shown filtered (open)? I shouldn't have any viruses or
spyware.

I haven't installed any SQL, FTP, HTML, or similar services to my
computer, because I mainly use my computer for surfing the net (and
some SSH connections). I have telnet disabled. I have Kerio Personal
Firewall, AntiVir Personal Edition, Microsoft Baseline Security
Analyzer, Ad-aware, Spybot, BHODemon, etc., and I haven't found any
viruses or spyware from my computer.

Result of the port scan:

PORT STATE SERVICE
135/tcp filtered msrpc
376/tcp filtered nip
1434/tcp filtered ms-sql-m

Result of the port scan:
PORT STATE SERVICE
135/tcp filtered msrpc

That will always be there,...no matter what. It can't function on the LAN
properly without it.

376/tcp filtered nip

Don't know.

1434/tcp filtered ms-sql-m

You may have an Application on the box that uses MSDE as a "backend
database".

Don't know.

Me neither. But I found some info:

(1) The official port list by IANA and RFC 1700 say:

nip 376/tcp Amiga Envoy Network Inquiry Proto
http://www.iana.org/assignments/port-numbers
http://www.faqs.org/rfcs/rfc1700.html

(2) From the Google Groups Usenet archive I found this message:

Subject: Re: Problem with Envoy & AmiTCP
Date: 1998/06/29
recently applied at the IANA for a port number and I couldn't help
noticing that an IP port number (376, if I'm not mistaken) was assigned to
Amiga Envoy. Now I don't know whether it has ever been used by existing
releases (for other purposes?) or not; my guess is that in the former case
the (AFAIK undocumented) protocol could be reworked, while in the latter
you simply implement "tunneling over TCP/UDP" using the reserved port.
Just my Lit. 0.02.

And I still found more (Amiga Envoy related) info:

Amiga Networking Frequently Asked Questions (FAQ) Part 2/2
Amiga Envoy is the Amiga peer-to-peer networking software developed by
Commodore's Amiga Networking Group. Included applications enable connected
Amiga
computers to share hard disks, CD-ROMs, and printers transparently. Amiga
Envoy
also provides a simple messaging interface (API) for the easy development of
reliable network applications.
Envoy 2.0 Requires Workbench 2.04, Kickstart 2.04, 512k RAM, SANA-II
compatible
networking hardware.
Workbench 3.1, 1MB or more of RAM and HD recommended.

Envoy 3
Amiga Envoy is the only networking software specifically designed for Amiga
computers. It allows you to access resources like files and directories on
connected Amiga computers as if they were on a local disk. Naturally, this
also includes removable media support. Printing over the network is also a
feature of Amiga Envoy. A single printer can even be accessed by multiple
Amiga computers simultaneously.
Requirements:
AmigaOS 2.04 or better
Any SANA-II network hardware
Harddisk recommended

Networking FAQ
Q. I have an A2060 and A2065 networking board. Where can I get SANA-II
drivers for these cards?
A. SANA-II drivers were never included with these boards. They are included
with Envoy, AmiTCP/IP 4 (the demo version) and they are also available in
the SANA-II development specification package.

Networking the Amiga to PC
Envoy is peer to peer networking software for the Amiga.Envoy lets you mount
drives from any Amiga on the network to any other Amiga on the network.
[...]
If you are planning on accessing the web from both Amigas or connecting to a
network with PC's involved get out some pen and paper.
Select Intermediate, proceed, proceed then select Hardisk. I then select the
SYS: Drawer.
Next up is enter the name of this Amiga's owner. (your name)
Then the name for your Amiga. examples, 1200, 3000, whatever you prefer to
call it but you will need a different name for the other Amiga.
Select Complex Network.
Please enter the network address for your Amiga. If this is your main Amiga
or server or gateway to the net the default address of 192.168.0.1 is
correct. (you should set the server up first).
If you are adding an Amiga to the network select the number of the machine.
ex; 192.168.0.2 or 192.168.0.4 Notice that only the last number changes.
Is your network using a default subnet mask? Yes
Do you want to select the default router? No
Please enter the name of your Amiga's Realm. NET
Please enter the network address of your Realm Server. 192.168.0.254 From
what I understand this default is wrong. Change the 254 to 1.
Select the networking hardware you are using with envoy. Self explanatory.
Proceed then click on the device in the Amiga you are setting up. ex
cnet.device Proceed
Enter the type number of IP packets for your network interface. 2048 I
change this to 2049 if you are going to run other networking software at the
same time. Such as Miami or AmiTCP.
I do the same to ARP packets. Change the default 2054 to 2055.
The reason I recomend changing those two numbers is Miami defaults to the
same numbers and sometimes the two networks will cause a lock up when using
them at the same time.
Please select which envoy services you would like to run. Since you can add
printers later just use the default File System.
You'll get the working on installation notice
Remove the Envoy Install disk and select proceed to reboot your Amiga.
