How to disconnect from OpenConnect?

I command something like this : sudo openconnect -b serverName for connect to vpn but when i want to disconnect it , the process does not kill and its alive in background.

I used these commands for disconnecting but they did not work for me in ubuntu 20.10 :

1-sudo killall openconnect

2-use ctrl + c

You can use something more powerful like kill -9.

First find out PID number like so:

pgrep openconnect
12345

After that, kill the process with: sudo kill -9 12345.

One liner can also be used

kill -9 `pgrep openconnect`

IF you have more than one and want to script it you can run this:

pgrep openconnect | while read line ; do sudo kill -9 $line ; done
