What is UDP port 626?

I use my XServe Mac OS X 10.5.x with 2 x network interfaces as a Firewall.
ipfw shows the below as the very first line:
00001 allow udp from any 626 to any dst-port 626
I do not have above in my ipfw.conf file. Would I be correct in assuming it's an Apple default rule?
The IANA list shows below:
asia 626/tcp ASIA
asia 626/udp ASIA
# Michael Dasenbrock <[email protected]>
I cannot get any information in regards to the ASIA application/protocol.
What is ASIA? Does having port 626 open pose a security risk? There is in fact traffic continuously being allowed through by this firewall rule.
Can anyone clarify what exactly port 626 traffic is?

Port 626 is used by serialnumberd, the tool that tracks serial number usage on your server (to ensure that the same serial number isn't being used twice). I don't know the implications of disabling it, but I don't run the firewall on any of my servers anyway.

What TCP/UDP ports need to be open for Cisco VPN Client version 4.8 to work?
Thanks,

Normally, you need the following ports and protocol :
UDP 500
UDP 4500
ESP
In case, you are using IPSec over TCP you have to open, TCP port 10000 or any other port you want to use for IPSec connections (Its configurable).

Anybody know what tcp or udp port # is used by Server Monitor?

Hi everyone. I've been lookin' all over ****'s half-acre to find out what port # is required for Server Monitor with no luck. Sure, I can access the local IP address on the LAN, but for LOM to be truly useful...I need to access from WAN. Since my public IP takes me direct to the server itself (and other ports on that ip do other things), I really need to know what port # is used to forward Server Monitor traffic. Anyone?
Thanks!

I do have this link to well known TCP and UDP ports used by Apple software products.
I am fairly certain the answer lies within.

Noticed that my MAC Mini is sending traffic to 70.38.54.77 on sequential UDP ports (port scanning?)

Hi,
I noticed in my home router logs that my MAC Mini "scans" UDP ports in the 33xxx range to an address 70.38.54.77 ... a quick search shows others complains but not result or explanation. I am looking to see if this is some piece of sw installed in my MAC or perhaps how to block traffic to/from that IP (or its subnet).
See below - .149 is my MAC mini IP address at home.

Listen to specific UDP Port

Hi guys,
I'm using a PHP script which contacts my Mac running growl to subsequently push notifications to my iPhone via Prowl.
This isn't working at all at the moment and it's proving difficult to establish whether A - the PHP script isn't contacting the Mac correctly or B - a firewall or equivalent is blocking access to Growl.
My set up is:
1. iMac running Growl and growl-notify;
2. a DynDNS account which points to my IP address;
3. Netgear router which forwards UDP port 9887 to my iMac (which has been allocated a static local IP address);
Is there anyway I can 'listen' to port 9887 to see what information is being received at that port? That way I can determine whether the plugin has been configured correctly or whether the script is generating an incorrect packet.
Thank you for your time.

Try Wireshark.

Monitor a UDP port

Hi,
I could find a solution for my problem. I need to monitor a UDP port.
For the TCP ports i'm using MP template TCP Port, but for the UDP i don't find any tool.
My question is. It's possible to monitor UPD ports in SCOM 2012 R2? If yes, how?
Thank you,
Rui

Hi Rui,
I have found a possibility to do this. Hope you understand this and it is helpful. This is a two step process but guess will definitely server the purpose.
Scope: We will be running a tool which will monitor a port (TCP or UDP) for a specific host / IP and will throw a log file.
SCOM will monitor the log file and will throw a alert if the log file contains the string NOT LISTENING (Port not working or unable to open the port) which the program will create the log with the results.
First download the program named: PortQry Command Line Port Scanner Version 2.0 from microsoft using the below link. It is a command line tool.
http://www.microsoft.com/en-in/download/details.aspx?id=17148
Run it using by making a batch file or powershell script using task scheduler as per your time requirement (Every 5 min or 1Hr).
Use this command to monitor a ip / hostname and its port with TCP or UDP.
I have pasted the command file of the program in C:\Port_checker directory so i am using the below syntax
C:\Port_checker\PortQry.exe -N 192.168.1.1 -e 5723 -p UDP -l C:\Port_checker\Result.log /y
-N = Hostname / FQDN of agent or Ip address
-E = Port # what you want to monitor
-P = Protocol (TCP or UDP)
-L = Generate log on the following location and name
/Y = To replace the existing log file name to fresh one without prompt.
The result in the log file will be as follows:
============================
For successful port open:
PortQry Version 2.0 Log File
System Date: Tue Oct 07 09:42:32 2014
Command run:
C:\PortQryV2\PortQry.exe -N 192.168.1.1 -e 5723 -p UDP -l C:\Portqryv2\Result.log /y
Local computer name:
192.168.1.2
Querying target system called:
192.168.1.1
Attempting to resolve name to IP address...
Name resolved to 192.168.1.1
querying...
UDP port 5723 (unknown service): LISTENING
========= end of log file =========
PortQry developed by Tim Rains
For failure port open:
PortQry Version 2.0 Log File
System Date: Tue Oct 07 09:42:32 2014
Command run:
C:\PortQryV2\PortQry.exe -N 192.168.1.1 -e 5723 -p UDP -l C:\Portqryv2\Result.log /y
Local computer name:
192.168.1.2
Querying target system called:
192.168.1.1
Attempting to resolve name to IP address...
Name resolved to 192.168.1.1
querying...
UDP port 5723 (unknown service): NOT LISTENING
========= end of log file =========
PortQry developed by Tim Rains
Now as per the above results NOT LISTENING Port is blocked or is not opened and LISTENING
means working or port is opened.
So now using SCOM you will monitor the log file Result.log
in the location C:\Port_checker\ saying if NOT LISTENING
comes in the log file throw me a alert in SCOM consle or via email.
To configure that alert you need to create a Generic text log alerting Rule which will throw a alert if any thing added in that log which is not to be added and if it is added like NOT LISTENING
then it will throw a alert.
Refer this link on how to open a Generic text log alerting Rule.

How to unblock UDP ports from the firewall of the Time Capsule

Hello i just bought a time capsule and i am trying am using it as a router. I am trying to use Shakespeer
that is like a server where you share files within the University,it runs with Dtella. However, when y try to get online a message tells me that the firewall of the router is blocking the UDP ports needed....how do i unblock those UDP ports so i can get online?
Here is the message:
In order for Dtella to communicate properly, it needs to receive UDP traffic
[19:14] <*Dtella> from the Internet. Dtella is currently listening on UDP port 4000, but the
[19:14] <*Dtella> packets appear to be getting blocked, most likely by a firewall or a router. If
[19:14] <*Dtella> this is the case, then you will have to configure your firewall or router to
[19:14] <*Dtella> allow UDP traffic through on this port. You may tell Dtella to use a different
[19:14] <*Dtella> port from now on by typing !UDP followed by a number.

Hello albertoPeralta. Welcome to the Apple Discussions!
To open ports on the Time Capsule, you would use the AirPort Utility to configure Port Mapping.
AEBSn - Port Mapping Setup
To setup port mapping on an 802.11n AirPort Extreme Base Station (AEBSn), either connect to the AEBSn's wireless network or temporarily connect directly, using an Ethernet cable, to one of the LAN port of the AEBSn, and then use the AirPort Utility, in Manual Setup, to make these settings:
1. Reserve a DHCP-provided IP address for the Shakespeer host device.
Internet > DHCP tab
o On the DHCP tab, click the "+" (Add) button to enter DHCP Reservations.
o Description: <enter the desired description of the host device>
o Reserve address by: MAC Address
o Click Continue.
o MAC Address: <enter the MAC (what Apple calls Ethernet ID if you are using wired or AirPort ID if wireless) hardware address of the host computer>
o IPv4 Address: <enter the desired IP address>
o Click Done.
2. Setup Port Mapping on the AEBSn.
Advanced > Port Mapping tab
o Click the "+" (Add) button
o Public UDP Port(s): 4000
o Private IP Address: <enter the IP address of the host server>
o Private UDP Port(s): 4000
o Click "Continue"

QOS Network Planning - TCP/UDP Ports used in CWMS 2.5 MDC deployment

Does anyone know if there is documentation that describes the WAN traffic in CWMS 2.5 MDC? I'm looking for the TCP/UDP ports that must be prioritized on the WAN to properly class our traffic between the two data centers. I can't find any such document.
Thanks,

HI Matt,

Forwarding UDP port for Remote Desktop Gateway

What is the correct way to forward UDP 3391 port for RDG server?
What direction should I choose for UDP port parameters? "Receive" or "Receive Send" or something else?

Aurimas N, Were you able to get RemtoteFX working through TMG? I have the same issue whre I can not get UDP working with clients conneciting over the WAN. Can you tell me specifically how you got this to work on your TMG?
Thanks
I am not sure how to check to be honest, on TMG I only see 443 port being used, and since it is remoteApp there is no connection indicator, or I don't know how to access it.

OS/X unresponsive while broadcasting to UDP port 2223

At least once a week I have to power-cycle the iMac my kids use for their homework, because they cannot wait the few hours it takes to recover by itself.
During that time all we get from the iMac is the rainbow wheel of death,
and on the network I can see it is sending broadcasts to UDP port 2223 (rockwell-csp3). It also insists on sending NetBIOS name lookups - (despite nothing in the system preferences saying to use anything but DNS), installing a samba server on the network at least provides something to answer those lookups (but it shouldn't be necessary).
I'm guessing that the Microsoft Office (2008) installed on the machine is somehow responsible - but a computer that is catatonic for hours at a time is useless.
Anyone know of anything I can do to stop this, or something I can put on the network (other than a windows machine), that might make it happy?

Is there a chance that someone has installed some kind of
software on the computer that is trying to "call home?"
The app known as Little Snitch can tell what may be in there
and if it is responsible for these odd network calls out.
How is the port security set up in the Mac? And why would
those ports need to be open unless there was a real purpose?
With my Macs, all of the ports in Firewall are closed to access
except for the Network Time Server to keep the clock correct.
{Some are used to share files between computers, & to chat; etc.}
Do you have more than two user accounts in the computer, and
if so, is your Admin account only used to update and maintain
the OS X & to install apps for other users? The levels of security
in Mac OS X can be controlled; and such odd port calls if or when
there is no need, are signs that something is not quite right.
Have you looked into the Console utility to see what is causing the
hang at those time intervals you know this has happened? There
are several different logs and reports in there; some won't apply.
Do the children who use the computer, have access to or know the
Admin account's password? A second user, from their account, can
install software and do other things, if that password is available.
I noticed you had a similar post last month that appeared to go without
a reply; now it is locked and can't be replied to anyway. So this issue
has been going on for some time. What may have happened in the past
year or so, to start this issue in that computer? Something, for certain.
Good luck & happy computing!

Incoming RTP traffic blocked by SPA112 ATA: UDP port unreachable

Hi folks,
I'm using a Cisco SPA112 ATA behind a NAT, where port 5060,5061 and 16384-16482 are forwarded. Registration to the SIP proxy also works fine. However, I'm struggling with audio issues, meaning that the RTP session is not setup properly.
When investigating this issue at the packet-level, I found that the ATA itself is blocking traffic:
21:00:21.857655 IP 192.168.x.y > 82.197.a.b: ICMP 192.168.x.y udp port 16452 unreachable, length 208
The blocked port number depends per session, but is always between 16384 and 16482.
Actually, the issue sounds very much like in [1]. However, the proposed solution (disabling CDP) is not of any help to me, since it's disabled on my ATA by default. Any clue what could be the reason for this behaviour? Your help is greatly appreciated.

Hi,
You can try this packet Tracer:-
packet input outside udp <External Source Ip on the internet> 45657 <Outside interface IP> 43139 det
For the captures , you just need to verify that the ASA device is passing the traffic through as this is UDP traffic , we would not be able to find much.
For more information on captures:-
