When i checked with taskmanager it is svchost.exe. If i am looking for “HTTP://*:8855/” this binding the process ID is 19552. Request queue name: Request queue is unnamed.
Well the command results not exactly user friendly to show which PID matching which binding.But each session id order also match on printed request queue result. if you check the request queues section in results you can also see process identifiers. It will give you all bindings for registered sessions. HTTP.SYS is a kernel driver so runs under system process obviously.Įven you can use C# “HttpListener” to create small program that listen on a port by utulizing http.sys easily.īut is there any way to see which process actually using http.sys and bind this port ? On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the well. They are used by system processes that provide widely used types of network services. System process is only serving requested port for another process if your application utilize http.sys driver. The port numbers in the range from 0 to 1023 (0 to 2 10 1) are the well-known ports or system ports.
Well, I can tell you, definetly it is not “system” process itself. Well it is easy to understand if your server installed Web Server like Apache, IIS or IISExpress to figure out who is using it but what if you don’t have any web server in your machine but who is then using port 80 ? OS itself ? I guess there must be a logical explanation for this.Įdited by Mis3ry99, 27 July 2021 - 03:29 AM.In normal conditions there are several ways to check ports on a system.And there are lots of tools around like SysInternals, TCPView or good old “netstat -ano”.īut wait a minute, if we look netstat -ano Īs you can see my port 80 is reserved by “System” process (where PID=4).
On a side note, even though when I'm offline, my antivirus program (according to the PID)uses a remote connection to a foreign ip using port 443 and it is the only connection being shown by PortExpert in that scenario. My understanding about this process is very limited. Not sure how to feel about the svchost connections though. So I ran through each single PID and I found out that they were all tied to either my antivirus program, it's PC booster program, VPN and the likes or svchost. After restarting PE the connection showed up again alongside multiple processes that were using port 80 as well. A shame because I wanted to further review the Windows® connection I initially thought, but it got even better. I hope this was just a coincidence due to the shutup10 changes. Then I deactivated a ton of stuff in shutup10.Īfter reconnecting to the internet, PortExpert magically closed without warning. I disconnected from the internet and ran the adwcleaner and all it found was a web companion from lavasoft that was supposed to protect me while surfing, so my guess is that this was a false positive. Tools > Options > Advanced > Connection Uncheck 'Use Port 80 and 443 for incoming connections' Or set Apache’s Startup type as Automatic, this way Apache might start before Skype does, and will be able to bind to port 80 and 443 before any other application has a chance to take these ports.
