  • Why there is no good task manager and system monitoring software on linux?
    It's basically like https://learn.microsoft.com/en-us/sysinternals/downloads/tcpview but for Linux. Source: 10 months ago
  • Some people prefer using DCS on Steam for the download speed, yet I get my whole 1Gbps bw used every time with the ED installer. What is the deal?
    Unfortunately I don't think there is an existing list of CDN endpoints to pick from, I found a few by starting updates while using a VPN and using tcpview to find which IP address it was connecting to. Once I'd found one that was faster than the default I opened my hosts file: C:\Windows\System32\drivers\etc\hosts. Source: 11 months ago
  • How do I know what ports an application is using?
    Try https://learn.microsoft.com/en-us/sysinternals/downloads/tcpview and it will show you in real time what ports are being used to connect to there. Source: 11 months ago
  • How to detect RCE/arbitrary code injection/RAT's from video games
    Maybe something like TCPView: https://learn.microsoft.com/en-us/sysinternals/downloads/tcpview. Source: about 1 year ago
  • strange remote listeners from private ip with "winrm" command
    I understand that netstat isnt exactly user friendly so if you'd like to keep monitoring the situation you can use SysInternal's TCPView https://learn.microsoft.com/en-us/sysinternals/downloads/tcpview which displays everything for you in a GUI. Just don't forget to filter for only listening ports cause it will show all connection states by default (use the green flag icon). It even has the added benefit of... Source: about 1 year ago
  • Norton Strikes Again
    And finally TCPView will show you what network connections your processes are trying to make - great for detecting backdoors, botnets and trojan horse viruses trying to phone home. Source: about 1 year ago
  • Opinions on the Essential Mod?
    You can use also use TCPview to see all connections that are being made on your computer then run them through a website like whois to figure out where the connection comes from. Anything from Microsoft will likely be fine. Cloudflare or Amazon (maybe google too) might be points of interest. Source: about 1 year ago
  • Native Instruments hitting ws-sync-prd.sounds.com 14k times a day
    But that still didn't get me the app. I did a lot of back and forth with ChatGPT and tried various network sniffers (e.g. wireshark) which I could isolate down to the OpenDNS IP and get the ports and protocol of the request, but not the process. I ended up using TCPView, which shows the processes but still nothing popped up consistently. I used pi-hole to resolve ws-sync-prd.sounds.com to IP 1.2.3.4 so I could... Source: about 1 year ago
  • Microsoft swears it's not coming for your data with scan for old Office versions
    There's also SysInternals TCPView. Few things in life will make you more paranoid than watching this thing for a few minutes. Source: about 1 year ago
  • Frequent freezing with otherwise good connections
    [2] https://learn.microsoft.com/en-us/sysinternals/downloads/tcpview. Source: over 1 year ago
  • Anon plays a game
    And TCPView straight from Microsoft's own website is basically a GUI version of netstat, I'd see anything listening for connections there. Source: over 1 year ago
  • Port used by ffxiv
    Regarding 2, the vanilla FFXIV client doesn't use sockets for IPC, so you're right about one thing -- it shouldn't be talking to localhost. The only reasonable explanations I can come up with are: mods, malware, or misinterpretation. I don't mean to insinuate anything, but before we go chasing after ghosts, I just want to make sure that we have accurate information. Are you sure it has an open localhost socket?...

  • Documenting server communication ports and IPs
    TCP view may help: https://learn.microsoft.com/en-us/sysinternals/downloads/tcpview. Source: over 1 year ago
  • Suddenly, after a restart, I'm getting this error when trying to start my berdrock server on Win10, it have been working for a year without problems
    There's a Microsoft app called TCPView (v4.17 is the latest). If you run it and look in the "State" column and sort/filter for "Listen", you can find exactly the other program has that TCP port (usually 25565) occupied. Source: over 1 year ago
  • Thousands of Popular Websites See What You Type–Before You Hit Submit
    Not browser extensions, but firewalls where you can monitor your traffic on the OS: https://github.com/evilsocket/opensnitch (Linux) https://www.obdev.at/products/littlesnitch/index.html (Mac) https://www.glasswire.com/ (Windows) https://docs.microsoft.com/en-us/sysinternals/downloads/tcpview (Windows). - Source: Hacker News / almost 2 years ago
  • Unable to cast tabs or desktop from PC
    Software analysis tool (windows) TCPView Https://docs.microsoft.com/en-us/sysinternals/downloads/tcpview. Source: about 2 years ago
  • Ask /r/razer: What does `RzSDKServer.exe` do, and why does it block port 1337 on Windows 10?
    I found out that uses the port by doing a netstat -ab in cmd and then using Sysinternals TCPView to kill the process. Source: about 2 years ago
  • Is internet bandwidth being used?
    For windows use tcp view to see what is connected and using bandwidth. Or log into your modems admin page Https://docs.microsoft.com/en-us/sysinternals/downloads/tcpview. Source: about 2 years ago
  • I have network latency spikes after installing kaspersky
    You might enjoy having TCPView to look at your processes and their outgoing/incoming connections. It's like netstat only it names the processes instead of just giving the PIDs. Source: about 2 years ago
  • If I Delete The Full Directory Will It Stop The Default Page
    If you can't find it, I seem to remember SysInternals had a good utility TCP VIew which should show what is running on port 8080. Source: over 2 years ago
  • New to Docker, error: [address already in use :::80] even though host port isn't 80
    Before starting the container verify the port is not in use with tcpview. Source: over 2 years ago
