I've installed Nessus on a fresh Ubuntu Server Install using the following steps:

$ sudo apt-get install nessusd nessus nessus-plugins
$ sudo update-rc.d nessusd defaults
$ sudo ln -s /etc/init.d/nessusd /etc/rc2.d/S20nessusd
$ sudo /etc/init.d/nessusd start
$ sudo nessus-adduser
$ sudo /etc/init.d/nessusd restart
$ nessus

I would like to use and manage it entirely from the command line. However, when I try to run it (see last step), I get the following error:

(nessus:8548): Gtk-WARNING **: cannot open display:

Can I get some advice on how to configure this to run without X-windows?

Thanks!

Well...as nessus is a GUI program, and not a CLi program, this could very well be a bit daunting to try and get it to work via the CLi...

Might I suggest you use some solid CLi programs that do what it is you are looking for nessus to do? They are out there, just browse the repositories.

Cheers,
Ghost

Funny enough, the windows forum I'm on sent me the documentation with the unix commands and non-gui instructions so I'm all set. Thanks for responding though.
