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?

I attempted to install a software package on a server and the installation failed due to an existing application using the desired port.  Since it was a non-standard port, I didn't know what was using the port but I needed to find it and either kill it or move it.

Let's say for example, we're looking for the process living on port 3389 (the remote desktop / terminal services port).  First, we run:

netstat -ano | findstr :3389

The return should present you with several lines.  One of them should look like this:

TCP    LISTENING    [processid]

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.

Kind of an odd issue.  Ran:

sudo apt-get update

And was presented with:

Sometimes you come across something weird and this was definitely one of those instances.  I honestly don't know what I did to get here but I found myself unable to drag and drop icons.  I attempted to drag an item to the recycle bin but no such luck.

The maximum length filename (which includes the full path) cannot exceed 255 characters.  Just to be clear, that includes the directory name, spaces, punctuation or anything else that would appear in the address bar.  For example:


The above is 34 characters in length.
