First kill the earlier process and then start the server again.

@svenkatsai1

points that there’s some other application(or most probably an instance of the same application opened previously but haven’t terminated yet - see Orphaned processes ) using the port you have assigned for the server. You can ascertain if that’s the case, using netstat command to check if there’s a listing for the port you want to use.

Now, what to do about it?

  • Kill the process using the port - If you are sure that the killing the process occupying your port won’t be a disaster, you can use ps command to find the processes id and use it to kill the process

  • For the purpose of testing the server, assign a different port for your server in vsftpd.conf and before submitting for assessment revert it to the required port.

Other vsftpd_v1 process is already running. Kill the other running process, first get the PID of the vsftpd_v1 process using ps command and then use kill -9 PID to kill the process.
Run vsftpd_v1 again.
