Visual Studio Code leaving port open

Running a port scan via Network Utility on OS X 10.14.5, turns up two different outcomes, depending on whether or not I have Visual Studio Code (1.35.1) open.

If the application is open, I’ll get random ports around 64500 open as well, if not, these open ports disappear.

I’ve set up Little Snitch to prevent connections in/out from VSC (which may be overkill), but:

  1. How much of a risk is it to have these random ports open on my machine while I’m using Code?
  2. What other steps can I take to prevent any malicious behavior through these ports?

How can I forward a port on my VPS using Ubuntu 18.04?

I am new to ubuntu as of now and need to simply forward a port on my VPS. I do not have access to the router it is connected to over WIFI as it is in a remote location. I have been researching and have seen a lot about iptables and such. I just got Ubuntu installed on this so everything is brand new. I can run the command iptables so it’s installed. I havent created any new rules on my behalf, but I intsalled this thing called Docker and it seems to have forwarded the port 25565-25569 as I did using Pterodactyl Software I installed and used. Let me know if I need to use OpenSSH to port forward. Not sure what that is either.

If someone could tell me what commands I need to run in order to let traffic in and out on port 8372 that would be appreciated!

Heres my output I get when I run iptables --list: https://pastebin.com/FDkS3A9Z

xrandr doesn’t show hdmi port

I have a laptop, Ubuntu 18.04 LTS, Intel 630 HD Graphics There is a VGA-port and a HDMI-port. Yesterday both worked, I have two displays, connected with the laptop. Today suddenly the monitor connected with the HDMI was not working anymore, no signal. Here is the output of xrandr:

Jack Audio – Headphone port

I run Ubuntu Studio 19.04 on a HP AMD laptop. I am relatively novice at linux.

I am using Jack audio to run sound for SuperCollider, Ardour, PureData etc.. and I am bridging it to system (puluseaudio sink/source) using ‘ubuntu studio control’

I get sound from the speakers but not from headohones even when I restart jack after inserting headpohones. The only way I get sound on headphone port is if I boot with headphones connected.

Is this a Ubuntu Studio/Jack/PulsuAudioBridge bug or could there be a problem on my end?

Please help me

How can I change PulseAudio port priorities?

I list sources and sinks as follows:

pactl list sources pactl list sinks 

The output I get is:

...     Ports:         analog-input-internal-mic: Internal Microphone (priority: 8900)         analog-input-headphone-mic: Microphone (priority: 8700)         analog-input-headset-mic: Headset Microphone (priority: 8800) ...     Ports:         analog-output-speaker: Speakers (priority: 10000)         analog-output-headphones: Headphones (priority: 9000, available)  

How do I change the priorities listed above and have them fixed at what I change them to? Note that I am not looking to set a default source and sink or to delete unwanted sources or sinks, I just want to be able to assign them different priorities.

Can monit be used to test if port is open without sending data?

I’ve tried to use monit to test if my port is open with a config option:

if failed port 12345 type tcp with timeout 15 seconds then restart 

however when monit sends test data to the port, the application crashes. I want to monitor if the port is open without sending any data to the port, i.e checking if netstat -l | grep 12345 returns something from my monit script. Is there a way to achieve this with exec?

Tor relay on port 9001 TCP

I executed netstat -t on my linux terminal and noticied a tor relay running on port 9001. I’ve search about the IP address of relay on shodan and got a result that address is from Russia, after that i have “googled” it and found some websites saying this can be a malware, a trojan or a spyware, nothing more. Can someone explain me what it can be? Is really a trojan or a spyware or is normal?

OBS: When i perform netstat -t any tor service or Tor Browser is running. I also run sudo service tor stop to confirm.

Windows IIS 10 not working over port 443 (HTTPS)

I can’t access my server hosted on IIS 10 outside my LAN over the port 443 (HTTPS), I’m using Cloudflare’s SSL, I’ve already added the origin certificate in IIS, changed the binding setting to port 443, “white listed” the port 443 on Windows firewall, forwarded the port 443 in the router settings… And it still doesn’t work, does anyone have a solution? Thank you, Alex
