You get a shell on a linux box, you attempt to upgrade the shell to meterpreter using the command "sessions -u", and then you receive the following error:

"Shells on the target platform, linux, cannot be upgraded to meterpreter at this time."

I remember when I would get this error -- seemed like the kiss of death as far as trying to maneuver once I got a shell.  I'd flounder around, trying to figure out how to accomplish the task at hand but this issue would severely limit my ability.

Somewhere along the way, I discovered the cause -- you don't have a TTY.   What do you do?

There are quite a few reverse shell examples available to you on the Internet.  You can also find a large collection under /usr/share/webshells on the Kali Linux distro.  That said, the other day, I need a small perl script to insert into an application which I could trigger.  A one liner wouldn’t work and the more elaborate examples also wouldn’t work.  I came up with the following from something I found in a search, hopefully you can put this to good use.
