After a long time of worrying about my network being secure and finally understanding the basic job of the ports I would see open. I recently noticed port 2103 Zephyr-clt and port 2105 eklogin open on my daughters computer. I asked her if she was "Instant Messaging" as that seemed like what the ports were for, but she said no. It was near midnight but I did not think she would fib about it? She did just add a printer that day. Can anyone tell me why these would suddenly appear open?
port like zephyr-clt and msmq are used by some antivirus application like Kaspersky and other, to monitor the devices like printer and router which might be connected to machine , so, that an antivirus program can also prevent network attacks. you can stop them , by disabling your antivirus network defender option.

I'm working with server automation tools on some Dell C2100 and C1100 servers. What I intend to do is connecting via Serial Over Lan using ipmi.
A few weeks ago, I was able to connect to one of my servers using ipmi-console (from freeipmi), like this:
ipmi-console -h IPADDRESS -u USER -P
This started up a SOL connection, and this way I was able to automate some interactions with the server's BIOS settings and other stuff.
However, a few days later, the same script didn't work anymore. It just says "[SOL established]", and that's it: the SOL connection never shows any feedback, and it stays idle until I close the connection.
My question is: what could possibly have changed that the SOL connection is not working anymore.
I obviously checked for anything related to SOL and IPMI, both in BIOS settings and using BMC web GUI. But everything looks normal, and I didn't recall to have changed anything there between the time the connections worked and then they stopped working. IDK what else to check, and it just fails w/o errors anywhere.
Perhaps this is a common thing with IPMI and/or SOL, but I frankly don't understand it. So, any pointer would be nice.
Thanks in advance.
FreeIPMI maintainer here. When no data is being output, it is typically a configuration problem. Assuming none of that changed, one idea.
On some motherboards, I've seen the BMC internally "lose its connection" to the serial chip, thus it doesn't get any serial data and thus doesn't have anything to send out. Unfortunately a hard power reset is often needed to solve this (b/c the BMC always is "on" via standby power, it must be a hard reset to reset it). Hard resetting the BMC directly might work as well, you can do this in FreeIPMI via bmc-device --cold-reset.
Finally, I've found what was going on.
It happened that somehow a value DID change on the BIOS settings, most likely my own mistake: remote connection ability was disabled. That means, it seems, that SOL works, but it doesn't redirect anything. Given that I was able to connect through SOL, it seemed obvious that remote connection ability was enabled.
Once enabled that BIOS setting, everything was back to normal.
BTW: freeipmi is awesome. Thanks for maintaining it Albert.
The title pretty much says it all. So, I have a no-break connected to my PC, because we have a lot of blackouts here where I live. The problem is: if I'm not at home, who will shutdown my PC correctly if there is a blackout? So, I realized that my modem is not connected to the no-break; this means that, in the case of a black-out, my modem will turn off, thus, no internet will reach my computer, so this is kind of a way to tell my PC when lights are out.
Sure, this might not be always the case (sometimes the internet just goes off for reasons other than power), but I will accept this risk.
So, what I am looking for is a code that, once I execute it (what I'll do when I'm leaving home), checks if there is internet conection. If yes, than do nothing and keep checking. If not, than shutdown the computer.
I am trying read traffic from a couple of test mobile devices, iphones, androids etc. I've done this for over a year using primarily Fiddler but also Charles. I did it up until yesterday without any issue. But today the devices do not appear to be connecting to my computer. I have confirmed that everything is configured right eg. device is set to use my computer as a proxy after I put in my computers IP address that I got by doing a simple ipconfig, sorry if this all sounds redundant but just letting you know my steps, better to have more information than less. I also turned off my firewall no change.
I thought perhaps something was done to our network, but I installed Fiddler on a coworkers computer and was able to proxy into that computer without any issue. Confirmed all drivers are up to date and really there was no change between yesterday and today except a deep scan with Malwarebites. Frankly sort of at a loss for what it might be, I have reinstalled Fiddler on my computer (the primary one I use, didn't reinstall Charles cause I don't want to deal with license issue right now) but at same time what are the chances that both stopped working at same time.
There's a high likelihood that your PC's firewall is blocking the inbound connection. You should check your firewall configuration to see if it's configured to allow inbound connections to Fiddler.
On your Fiddler-running PC, ensure Tools > Fiddler Options > Connections > Allow Remote Computers to connect is checked (if not, check it and restart).
From your co-worker's PC, try visiting http://<FiddlerPCName>:8888/ in the browser. Does the traffic appear in Fiddler?
I work while traveling at the moment. I'm at the point where I want to start setting up the paypal integration, but I can't because I can't open port 80 up so that paypal sandbox can communicate with my computer. I've tried getting my own USB modem w/ sim card (data plan) but it seems they are really aggressive with blocking ports on those also.
So, i can't get to the routers in the hotels since it would be wrong (and i don't have the passwords).
Is there some kind of trick that I can use so I can mess with paypal sandbox integration? I've tried using hosting (godaddy) but it's awful slow to keep uploading changes to a host just to see if what you did worked (not to mention problems with debugging).
Looks like i didn't get any help this time, but i found a way around it! I created a VPN in Windows 7 in my home network (so my work laptop can connect back home). I checked the setting that allows remote vpn connections to pick their own IP address so my work laptop would have a static ip.
I then simply opened up port 80, and forwarded it to the static IP set for my laptop. I can't believe it, but it works!
I would like to send a message, or something can be an advise from a pc to an another pc (only one, or at the most 2), the latter is powered off.
The pc which should send the message is a windows server 2003 os, instead the pc which should receive the message is a windows xp os.
The two machines are in the same domain and they work together through an ingres database.
The message will be sent at night, because there is an ingres database back up procedure that runs at night when my pc will be powered off, but when in the morning i will be at work I would like to read this message as a net send message, or something like
Unfortunately the net send command is disabled in our network, so I can't use it, but i'm looking a way for sending this message.
Have you any suggestion? thank you
Use age-old simple file based messaging.
Store a message in a specific file in the server and write a simple application which runs on startup on your machine to read it and display it.
And this is apart from rerun's great suggestion :)
There is breaking new technology available called email.
Is the machine powered off or in standby?
If if is in standby, then I will defer to someone who may have a better idea of how to get wake the machine to wake up programatically(sp?).
If it is powered off then read on...
If you have access to the machines bios settings, then I would suggest scheduling a power on event in the range of the time before the backup normally completes.
Then it is a matter of receiving the message and optionally shutting back down afterward?
If you are unable to change the bios settings, then does the machine "power on after power loss?" If so, get a programmable timer from the nearest retail store and power off before leaving at night and have the timer set to power on before the time the backup could reasonably be completed.
This is not really a software solution per se, but your problem does seem to be mostly hardware related (with the power off requirement and all...)
