ssh port forwarding

ssh-port-fwd
ssh -L 6060:127.0.0.1:6060 vagrant@192.168.34.11
golang pprof tool by default starts the pprof web server on localhost:6060. My pprof was running inside a VM and I needed to access the web server from the host. I could ssh to the VM. Thus I needed to enable port-forwarding on the host to the VM (remote).
ssh -L 6060:127.0.0.1:6060 vagrant@192.168.34.11
| | | |-------v------------|
| | | \--------------- remote ssh user@hostname
| | |
| | \--------- remote port to forward
| |
| \----------------- remote IP to forward ... in my case it was localhost
|
\------------------------ Local port to use for forwarding
After this I could use the web-browser on localhost:6060 __on the host__ to access the localhost:6060 on the VM.
[Update]
This even works with vagrant ssh.
vagrant ssh -- -L 6060:127.0.0.1:6060
