Port monitoring question

Hello,
I'm new to the forum and to Network programming in particular.
My question concerns port monitoring. I have a server transmitting UDP packets to a specific port. I need to have a thread that monitors that port and sees that there is traffic going out. Yet, it does not have any connection to the server (different processes), but it knows the IP and port number (actually the IP is the same).
How do I make it happen? Do I need to use a DatagramSocket and read inputs? Could someone advise with a simple code sample?
Thanks

Hi,
Why you dont simply create a DatagramSocket object. And using the receive message you can monitor datagrampackets, and if there is message or not available, simply use the getLength() method from this object.
You can do it in two ways.
One would be creating two threads, one to do the job, and the other one to monitor if there is or not message available. As you should know, the receives method, will block if there is no message available. As u dont want your program to freeze, put this job, in one thread.
The other one, would also be using a timertask, which will monitor the waiting process. If then for x time, it doenst receive, you finish your program.
There are really many many possibilities, u just need the DatagramSocket object, the DataGrampacket and a thread!
If i misunderstood something, you can give me new directions

Windows 8.1 Port Monitors

I would like to state up front that I have almost zero experience in the area of printer drivers, port monitors, etc., other than that which I have acquired so far during this project.
I am working on developing a PortMonitor that generates PS files in a predetermined location so that our Workflow system can collect them that I currently have set up to use the ghostpdf.inf file (came with GhostScript), which appears to use the PScript5
DLLs.
I would prefer to not use the ghostpdf.inf, but my own as I also want to be add a custom UI dll to the Printer GUI in order to allow display/control of the options available for our workflow (these options will vary based on the selected workflow).
I need this to be able to install and work on most platforms from Windows 7 upwards for both 32 & 64 bit Windows.
Having created a port I would like to be able to point it at the standard Microsoft PS Class Driver. When I do this on Windows 8.1 I get an error saying "Double check the printer name and make sure that the printer is connected to the network."
As I want this to go to file on disk I don't have a printer to connect to the network.
There are several, related, questions.
1. Can I, and if so how, do I overcome the 'printer connected... ' issue or do I just adapt the ghostpdf.inf file for my own purposes?
2. Can I, in the INF file, specify a custom UI dll so that I can manage the options?
3. Do I need to provided a custom driver dll as well or can I just have a UI dll if I plan to store the settings in the registry and have the port monitor dll pick them up and run with them?
Thanks,

Officejet 8600 Pro - software installation fails - "port monitor" issue

I am trying to resolve a completely different issue with my printer, so I thought it made sense to follow instructions from the very beginning. I have been printing successfully on this printer for a year at least. It is the best working printer I've ever had.
Back to the installation: Using Google Chrome as my browser, I downloaded the full package of software for the 8600. It came to about 118 MB. The installation process went smoothly - until the end. That is when I got the message that installation had failed. The error message said the software was unable to make connection with the "port monitor."
I am going to reboot and retry the installation. If it works, I'll come back and say so.
Thanks to all who assist us.

Hello-
Uninstall the printer completely. Once the printer is uninstalled , try the install again. Make sure to turn off any firewalls that you have on your PC before installing.
Also , when you install the printer, you should run the setup as administrator.
Click on start button (if Windows PC) and type %temp% in the search box.
This should open your temp folder. Once your in the folder , look for a file called 7z and a series of numbers.
Open the folder and scroll down to the bottom. Find the Setup.exe file and right click and run as Administrator.
I hope this helps.
Also, remember a click on the Kudos star to the left is a quick "Thanks" for a helpful post.

Port monitoring performance issues

We have 3500Xl series switches and some are running port monitoring so we can gather data on what kind of traffic is flowing through our network. The question is if 1 ethernet port is monitoring all the other ethernet ports on it, what kind of performance issues could we expect, if any. Is there a way to show the performance stats of the switch as well. For example, see below.

Hi,
I noticed you are attempting this on a 3500XL switch.I'll attach a useful reference to some constraints with SPAN on XL
http://www.cisco.com/en/US/partner/products/hw/switches/ps708/products_tech_note09186a008015c612.shtml#topic1
These older switches use a blocking, shared memory architecture and shared buffers for groups of 4 ports. One performance condition that is possible in this type of scenario is intermittent packet loss within the group of ports when traffic is high. This condition becomes probable when utilisation of ports start exceeding about 70% of bandwidth simultaneously on all ports. The symptom is intermittent because of the nature of traffic is typically bursty
Example:
Monitor port is 48.
Servers are 45,46,47 -100MB
Let's say a backup is run on the servers and all servers start to hit 70% of available bandwidth. If port is monitoring, then this is = 3 x 70MB = 210MB which exceeds monitor port.
Monitor port would see overruns drops etc
http://www.cisco.com/en/US/partner/products/hw/switches/ps607/products_tech_note09186a0080125913.shtml#troubleshoot_interface_errors
but the server ports could intermittently start dropping traffic because of available buffer taken up by monitor port. There's no real way to determine at what rate this will happen but something to keep an eye out for. You may isolate the monitor port to it's own group of 4.

SPAN Port Monitoring Setup

We have three Cicso Catalyst 3750 switches that are stacked. The primary switch has a VLAN ( # 99 ) setup on it. The VLAN has our incoming internet connection. The LAN ports from the two redundant firewalls are routed back to the primary switch ( non VLAN ). The WAN ports on the firewalls are connected to the VLAN. There are three unused ports ( 46, 47 & 48 ) available on the VLAN. There are also a couple of available ports ( 36 & 38 ) on the primary switch that are not in the VLAN.
We want to connect a hardware device to one of the ports on the switch that monitors network traffic. Need to connect two ports on the hardware device. One for LAN/WAN traffic, and one for the SPAN port.
Question:
Which port would you setup as the LAN port ?
Which port would you setup as the SPAN port ?
What commands would we run to set this up ?
Thanks

I would suggest moving this post here: https://supportforums.cisco.com/community/6016/lan-switching-and-routing
3750 isn't considered a small business switch.

HT3382 Connect from a MacBook Pro's mini display port to a Display Port monitor?

Hello everyone,
Is it possible to connect from a MacBook Pro's mini display port to a Display Port monitor with resolutions higher than 1920 x 1200? It seems Apple does not supply a mini-DP to DP adapter.
However, just as they do not make a mini-DP to HDMI adapter, but they do recommend a Belkin product for this purpose.
Is there any reason that a mini-DP to DP adapter or cable wouldn't work and support high resolutions?
Thanks for your feedback!

Hey tjk,
Thanks for the response.
Do you have any recommendations for a potential set up? The audio output and Apple DVI are on different sides of my MBP, which is alright, I guess I can get two long cables to handle each. I was hoping to just have my MBP closer to where I use it, with a cord nearby plugged in on one side to the HDTV and resting near where I keep my MBP for when I want to use the HDTV as an external monitor.
With a converter like this, you can run video out of the MBP's DVI port, and miniToslink (optical) audio out of the 3.5mm stereo mini jack to the converter, then it will combine the two and output audio and video through HDMI to the monitor.

Otherwise, depending on the TV's inputs, for video you could run DVI to DVI on the TV, or DVI to HDMI to the TV. For audio you could run 3.5mm stereo mini plug from the MBP to RCA adapter on the TV. Toslink/optical is also an option.

Daisy chain two display port monitors (Dell U2913WM) to new Mac mini Thunderbolt?

Everything I read said that I could hook up a display port monitor to a Thunderbolt port on the mac mini. I purchased two display port monitors (Dell U2913WM) that can be daisy chained, and hooked them up. All I get is mirroring. Does anyone know how to turn off mirroring with this setup? I did not get the "uncheck mirroring" option in preferences until I hooked up the second via the HDMI port instead of a daisy chain. The problem with that is, I cannot take advantage of the full resolution through the HDMI. It seems I have wasted my money on two monitors.
Looking for advice on:
1) How to daisy chain these two Dell monitors to the mac mini and turn off mirroring and use an extended desktop, or
2) How to take advantage of the full resolution through HDMI port?
Any help would be greatly appreciated.
Thanks!

So re-reading this thread, I now realize you did exactly what I wanted to do but your issue was having a cloned vs. extended desktop. Oops!
I believe your "nothing plugged in" issue is the cable. I'm not sure that TB cables are backwards compatible with DP - I think it's only the ports. Do you see multiple monitors in "System Preferences > Displays" if you hook the monitors up like you described in your OP?
My Dell U2713H arrived today and it works like a charm with the supplied Mini-DP to DP cable. The built-in display on my 13" mid 2009 MBP still works if not in clamshell mode, although I will mostly use mine in my HengeDock. In the OSD of the monitor, you can access "Display Settings > Display Info" and it will show you the DP capability. Mine is only DP 1.1a and I believe to run 2 of these at full resolution you will need the bandwidth in DP 1.2 which includes MST (daisy-chaining). This could be your problem.
Can you access the same menu in your OSD and report back what your DP compatability is?
Thanks!

[SQL QUERY] Select TCP Port Monitors and their related Watcher Node

Hi everybody,
I'm working on a SSRS report and SQL Query, I have no problem to find all my TCP Port Monitor (SCOM 2012 R2) based on the DisplayName, but I can't figure out how to get their related watcher nodes (in my case only 1 computer is a watcher node).
I can't find which table, which field, contains this information..?
Here is the query i started to write (i select * since i still searching for the right column):
SELECT
FROM StateView s
INNER JOIN BaseManagedEntity me on me.BaseManagedEntityId=s.BaseManagedEntityId
INNER JOIN MonitorView mv on mv.Id=s.MonitorId
INNER JOIN ManagedTypeView mtv on mtv.Id=s.TargetManagedEntityType
--where mv.DisplayName like 'Ping Target Status Check%'
AND me.IsDeleted = '0'
where mv.DisplayName like '%tcpmon%'
and mv.LanguageCode = 'ENU'
--and s.HealthState in (@state)
ORDER BY s.Lastmodified DESC
It would be great if someone can help me !
Thanks,
Julien

Hi,
After creating a TCP port monitor, we can find a table for this monitor under operationsmanager database :
SELECT *
FROM [OperationsManager].[dbo].[MT_TCPPortCheck_******WatcherComputersGroup]
You will find the warcher computer group.

Varying errors 1722 & 1726: Failed to add port monitor.

Hi guys,
I've got a problem installing the drivers for my litle HP deskjet 3050. I seem to be going around in circles.
I've had this problem before but solved it.....although I can't for the life of me remember how I did it. This time around I just can't seem to knock it on it's head.
The problem began after I reloaded an older system image backup after my HDD crashed (which I've replaced with a hybrid HDD). The printer wouldn't work from the moment I first tried after the reload.
I've followed every instruction on this forum I can find, from uninstalling, stopping/starting the spooler servie, cleaning out temporary files, switching off the firewall (including Norton Antivirus), reinstalling the software (which fails),etc.....nothing seems to get passed the point of the driver installation.
Have you guys got any ideas on what I must be overlooking?
Cheers,
Wayne.

you can use the java comm api and finished it.I suspect the OP means IP port and not serial/parallel

Could also have in mind a surveillance camera looking down over the docks.

Operations Manager 2012 - TCP Port Monitor

Hi,
Is it possible to have the TCP port monitor only alert if it fails on subsequent polls, instead of the single connection failure which is the default? We have 3 GPRS connections which intermittently
fail, so we only need to be alerted if they don't come back online after a 5-10 minute inverval and 2 failed connection attempts in a row. We have orchestrator so perhaps a runbook needs to be created?
Thanks

Hi,
Yes. The Runbook could do this trick. I think you need to make the monitors not to generate alerts when health state changes. Then use runbook to monitor the Health State, if some conditions are ture, an alert will be generated.
I am not so familiar with Orchestrator, you may ask at Orchestrator to get answered of how to design the Runbook.

Disable port monitoring task not working

Hi,
On SCOM 2012 SP1 the task "disable port monitoring" is not working. When I run it shows a success message but the port\interface keeps to be monitored on scom, the ports that I'm trying to disable the monitoring are members of the Relay Network
Adapters Group. Is there any way to fix this task or manually stop the monitoring of the port\interface ?

Hi Carlos,
By coincidence I ran into the same problem today.
It can be disabled by creating an override where you target the specific port object and set the parameter enabled=false.
I am not 100% sure this is the correct way but it works. I am assuming the disable port does something similar but I have to open up the task to confirm this.
For now I hope this helps.

SCOM 2012 SP1 Cisco Interface/Port Monitoring

Hey.
We are trying to finish our parallel rollout of SCOM 2012 (previously used 2007 R2 with xSNMP) and have ran into a snag with a port that goes to a T3 connecting two of our offices.
The device is a Cisco 7206 router (listed as Certified in the
latest lists). SCOM sees the port and labels it IF-47 (stupidly) during discovery and rediscovery, but won't apply any type of performance monitoring on it. I could create the override to enable one but the only monitors it shows are three rollups (High
Discard, High Error, and High Queue Drop percentages). We need to be able to monitor utilization like any other port on the router. Ironically, SCOM has added these monitors for disabled (admin-down) ports.
We have the other endpoint router in SCOM and have added the interface/port to the "Critical Network Adapters Group" but that only seems to monitor availability (up or down). So besides creating my own SNMP monitors from the Cisco OIDs needed, anyone
know of a way to get this interface/port monitored for performance (i.e. utilization)?
One peculiarity, if I look at the monitors between this interface/port and another that has the perf monitors this one has "Network Adapter (Common)" whereas the one with the perf monitors shows "netcor cisco" of multiple fashions.
thanks!

Some monitors are disabled by default. For details about the monitors, please see the section “Tuning Alerts for Network Monitoring” in the following document:
