I was following an instruction to deploy an application on a Virtualbox VM and I wanted to execute the long commands. By default it’s not possible to copy those command into the VM. VirtualBox has a shared clipboard feature which I tried to get it working but it didn’t happen so I didn’t dig into it and I came up with a funny hack :D I sent the commands through a socket :)
The Hack
nc or netcat is usually installed by default in some linux distros. So I opened a socket with nc on my host using the following command
nc -l 4567 # listen on 4567
and I connected to the socket from the VM by
nc 192.168.1.2 4567 | tee cmds.sh
the first part (before pipe) opens a socket to the remote address and the second part (after pipe) writes the received texts to a file named cmds.sh.
and then obviously I ran the commands I wanted via
sh -C cmds.sh
A fun hack ;)
P.S. Now that I think I could just open an ssh connection and execute the commands remotely :))
