I have an ELF executable on a server which doesn't allow scp transfers. It also doesn't allow outbound connections of any type. I don't have root access to it. Is there a way to copy this executable from the server? Maybe there is a way to dump object code to stdout, copy it and convert back to an executable on my end?
On the server, run base64 thefile. Then copy the output it produces. On your computer, run base64 -d > thefile, paste the output, then hit Ctrl+D.
