> Is port 4820 in use on the host (from a separate process of VirtualBox)?
Hi,
Just to add to erstazi's advice.
To confirm that port 4820 is available on the host, use `netstat -an'
If the port is in use and you wish to know the process, use a
combination of `fuser' and `ps'
Below is a working example on my machine using port 1527. In my case,
I'm port-forwarding using `ssh'
#
# Is port 1527 in-use?
#
pa...@oreo-1002-[pablo]: netstat -an|fgrep 1527
tcp 0 0 127.0.0.1:1527 0.0.0.0:* LISTEN
tcp 0 0 ::1:1527 :::* LISTEN
#
# Who is using port 1527??
#
root-r...@oreo-1001-[/root]: fuser -nu tcp 1527
1527/tcp: 12948(pablo)
#
# Some minimal information on the process: (sshd)
#
root-r...@oreo-1002-[/root]: ps -p 12948
PID TTY TIME CMD
12948 ? 00:00:00 sshd
