Macos – Remote Desktop Connection over VPN on mac

macosnetworkingremote desktopvpn

I'm trying to connect to a Windows computer on over a VPN connection using Remote Desktop connection.
I opened Network on mac and created a new connection.

Interface: VPN.
VPN Type: PPTP.

I filled the inputs for server address, account name, password and applied.
I connect the VPN and it connects. I open Remote Desktop Connection and put the IP of the machina i want to connect but it dont connect, a problem occurs saying that the machina may be turned off and etc. But in a windows machine I can connect there and the machine is up and running. On my mac I ping to the ip address that a want to connect and it has no response.

I think that the vpn have a problem, is there a way for me to certificate that i am on the vpn network ? Whats going on?

Just ran into this today. Looks like when you configure VPN in OSX, if you try to send traffic to a different subnet than what your vpn is connected to, it sends it out your normal interface as opposed to the tunnel. TO mitigate this, head to your VPN settings, click advanced and make sure "send all traffic through vpn" is selected.

If this is selected, then it's probably firewall configs and your SOL until you can get in and modify them.

Macos – Find (and kill) process locking port 3000 on Mac

You can try netstat
```
 netstat -vanp tcp | grep 3000
```
For macOS El Capitan and newer (or if your netstat doesn't support -p), use lsof
```
 lsof -i tcp:3000 
```
For Centos 7 use:
```
 netstat -vanp --tcp | grep 3000
```

Macos – Who is listening on a given TCP port on Mac OS X

On macOS Big Sur and later, use this command:

sudo lsof -i -P | grep LISTEN

or to just see just IPv4:

sudo lsof -nP -i4TCP:$PORT | grep LISTEN

On older versions, use one of the following forms:

sudo lsof -nP -iTCP:$PORT | grep LISTEN
sudo lsof -nP -i:$PORT | grep LISTEN

Substitute $PORT with the port number or a comma-separated list of port numbers.

Prepend sudo (followed by a space) if you need information on ports below #1024.

The -n flag is for displaying IP addresses instead of host names. This makes the command execute much faster, because DNS lookups to get the host names can be slow (several seconds or a minute for many hosts).

The -P flag is for displaying raw port numbers instead of resolved names like http, ftp or more esoteric service names like dpserve, socalia.

See the comments for more options.

For completeness, because frequently used together:

To kill the PID:

sudo kill -9 <PID>
# kill -9 60401
