UDP port 161 on IPCC/ICM servers

I am trying to setup Solarwinds monitoring via SNMP on our IPCC/ICM servers. The servers are AW, PGs and Router/Loggers.
Do the IPCC/ICM applications use UDP port 161? I cannot start the SNMP service on the servers due to UDP port 161 is already being used.
According to Windows task manager, the port is used by PID snmpdm.exe.
Any info or comment is appreciated. Thanks.

Yes it's not the same. Why, I do not know.
On ICM Windows boxes you use the MMC snapin, but on CVP you use the Ops Console which writes into cfg files and pushes them to the box.
At the end of the day the basics of community name, access list, trap destination are known by the agent on the ICM or CVP server.

Geoff

TS1629 Apple destination ip addresses for well known TCP and UDP ports used by Apple software products

I work for a large enterprise organisation with dual layer firewalls. The Apple article titled "allowing well known ports through the firewall "does not provide enough information on what the destination ip addresses of Apple servers are which host Apple ICloud services.
Does anyone have information on the destination Apple Ip addresses? So that I can lock down my firewall rules, just so that Apple devices, access Apple services on the Internet.
Many thanks

One option is to use "connection-reuse" cli under sip-ua configuration mode.
sip-ua
connection-reuse
This will enable the 7200 to create a connection with source and destination udp port number set to 5060. This feature is available in IOS 12.4(25d) which requires minimum of 256 / 512MB DRAM (depends on the feature set) and flash of 48 MB.

DMVPN-Why received packet doesn't use UDP port 4500 but 500?

Hello everyone
I got a problem with my DMVPN. Spoke is behind a NAT device. x.x.x.x is an public IP address which hub uses. I don't know why it discovered that the hub is also inside a NAT device. And after it sends a packet using port 4500, the received packet from hub was not using port 4500 but 500. I'm confused now. Any advise would be much appreciated.

This could be because the port 4500 packet that is being sent is not being received by the peer side or it is ignoring that packet.
Since the port 500 packet that you are receiving is a duplicate of the previous packet it is definitely not a reply packet for the port 4500 packet.
If you can get the debugs from the other end, then you could see if the peer side is receiving the udp port 4500 packets.
If not that then this could be a UDP port 4500 block with the ISP.

TCP/UDP Ports and site used by FEP to download updates - needed to allow on perimeter firewall

Can some one point me with information like what TCP/UDP ports are utilized by FEP and what DNS / site Name it uses to download FEP Updates. This is needed to tighten perimeter FireWall policies
Thank you

It should be the same as the documentation for all Software Updates:
https://technet.microsoft.com/en-us/library/bcf8ed65-3bea-4bec-8bc5-22d9e54f5a6d#BKMK_ConfigureFirewalls

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.

Identify Ports for AD - External UDP port scanner

Greetings all,
I am trying to figure out which UDP port is alarming on the "AD - External UDP port scanners (13005)" signature. By default, the signature is set to summarize which looks something like this "NumDestIps=100; currentTHreshold=100. protocol=1".
From the "Protocol = 1" line I am assuming all scanning is hitting up on a single destination protocol - I need to know which protocol / port number.
I've already attempted to turn on "log attacker, pair, and victim" packets. Verbose is not an option for this signature. I have also tried changing alert Frequency to "fire all" or just uncheck the "Summary Mode" box. None of this tells me the destination/victim port. I do see under a protocol field "ICMP" but i don't believe that pertains to the source port. Any ideas on how I might find this information?

TCP/445 is used by Microsoft file sharing (CIFS), and by default that port is opened on all Microsoft PC basically to allow file sharing.
If you open up DOS prompt, and type: netstat -na, you would see that your PC is by default listening on TCP/445.
Here is more information on Microsoft-DS (TCP/445):
http://www.linklogger.com/TCP445.htm
http://en.wikipedia.org/wiki/Server_Message_Block
So it really depends on your corporate security policy, whether to allow file sharing or not within the network. IPS is picking that up because it is an easier way of exploiting a PC since the port is opened by default.

Should I block TCP/UDP ports 135 to 139 on my router?

For the sake of Internet and Desktop security should I block TCP/UDP ports 135 to 139 both ways at all times on my router? This seems to be recommended for Windows environments. Does Mavericks need these ports for its proper operation? When tested, ports 135, 137,18 show as closed whereas all other ports are Stealth. Ideally, they should all be Stealth.

Have a read here: http://securityspread.com/2013/07/26/firewall/
Stealth is just as good as closed, some would argue that stealth is just as much of a giveaway of the port being present as it being closed.
The specific ports you mention pose no risk to OS X as far as I am aware.

Hi,
à
I need the UDP PORT 445 listed on SYSTEM Process.
à
Warning SYSTEM's UDP port 445 is not open or listening.
Based on your description, I’m a little confused with this issue. Please run following commands with administrator
permission and monitor the result. Would you please check and confirm whether any process listened the UDP port 445?
netstat –ab
netstat -a | find /i "445"
In addition, I noticed that you use Syshelp (Symantec validation tool) to check. I suggest that you would post
the warning message in Symantec Forum and confirm this issue. I believe we will get a better assistance there.
If anything I misunderstand, please don’t hesitate to let me know.
Hope this helps.
Best regards,
Justin Gu

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.

Does adding tcp udp ports on the nat exempt accesslist which is binded to nat 0 statement remove the entire nat 0 statement itself?

Hi Experts,
Is the above statement true?. I learnt later that adding tcp and udp ports on the nat 0 statements are supported . But does it take away the entire nat statement? Please answer my question at the earliest.
Regards
Krishna

Krishna,
"NAT exemption (nat 0 access-list command)—NAT exemption allows both translated and remote hosts to initiate connections. Like identity NAT, you do not limit translation for a host on specific interfaces; you must use NAT exemption for connections through all interfaces. However, NAT exemption does enable you to specify the real and destination addresses when determining the real addresses to translate (similar to policy NAT), so you have greater control using NAT exemption. However unlike policy NAT, NAT exemption does not consider the ports in the access list. NAT exemption also does not support connection settings, such as maximum TCP connections."
Reference
So, since the documentation clearly says that this rule does not consider any ports in the ACL, then one should not be testing unsupported configurations.
If one adds an ACL with specific ports, then unexpected results may be expected.
My suggestion, dont add any ACL entry with specific ports to your NAT exempt statement.
Thanks.
Portu.

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:

Attempting to resolve name to IP address...
Name resolved to 192.168.1.1

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:

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.

I'm running weblogic 8.1 on linux AS 3.0, whenever I bring it up, there is a process that listens on udp, although my weblogic runs on default tcp port 7001. What file or process opened with up port (32770)? I'm curious to know whats running with udp..
Thanks

Does anyone know why weblogic opens udp port/ which process maps to the port?
Thanks

10.6.5 firewall blocking udp ports used by ethernet MFC printer

Hi All, is there any way to apply a custom rule to allow access through the 10.6.5 firewall for a couple of UDP ports? I am trying to enable scanning from the front panel on a Brother MFC990CW with static IP on our local net (adsl router) and the printer docs specify up to 3 ports to be opened. Have played with IPFW via term but my rule attempts are not having any impact. Also unable to find log location where firewall activity is logged.
Would appreciate any tips.
Happy New Year

HI Michalien,
happy new years eve
have you tried adding the Image Capture Utility to the firewall? It Should open the port for you.
system preferences, security, advanced button, + button
navigate to Macintosh HD, Applications, Image Capture (witch handles most scanning in 10.6)
You may also need to add the cannon scan utility as well.

How to setup a UDP port forward range

Hi,
We are trying to figure out how to setup UDP port forward range. This is the configuration that we are using.
ip nat pool voip-rtp 10.10.10.3 10.10.10.3 netmask 255.255.255.0 type rotary
ip nat inside destination list 114 pool voip-rtp
access-list 114 permit udp any any range 16384 32767
Where 10.10.10.3 is the host I want to forward the ports 16384 to 32767 to.
This is not working. We use a similar set of commands for TCP range forwarding which work perfecting. Can anyone advise of the correct way to port forward a UDP range.
Damien

thanks for the suggestion.
I tried the same , but still the udp port 514 is not available. when i run nmap tool to scan the ports, the udp port 514 is not available to the external world and hence the syslog msgs i send to tat port is not being received. kindly help me out.
thanks again!!

Our IT Director will not allow the appropriate TCP and UDP ports to be opened on the district WAN

I have about 30 Apple TV Units and our IT Director will not allow the appropriate TCP and UDP ports to be opened on the district WAN. When our teachers try to log on to Apple TV to broadcast lessons, websites, etc., they are booted off the network after about 20 minutes.
Any ideas for how I might solve this without having to hard-wire the Apple TV Units?

Honestly, you do not.
Either the IT director will cave and allow the appropriate ports or it doesn't work.
Hard wiring the ATVs will not rectify the problem.
