I am working with a new client who lost their IT person and are trying to document what they have. It's a Linux/SunOS environment.
I am trying to find their Samba or equivalent user management server but so far have been unable to do so.
From a client machine, Windows or Linux, what is the best way to go about locating this server?
Use nmap and specify the ports to look for. A list of used port on samba is available here
history is also your best friend whenever you are going into a new environment. I would do this first so you dont' lose anything
history > history.txt
On all machines so you can preserve everything previous root user did
Also netstat -lan
You can see what servers it is currently connecting to and on what ports.
