Detecting wish OS a computer has !

[aliov]

Hi guys ,

I have the following situation , in the lab of my university we had a Linux machine with port 22 is open , i'm able to ping the machine but i'm not able to connect via ssh , i strongly believe since our group is not well organized , somebody changes this machine to a window$ machine , so is there is any way to detect the operating system of the machine .

some sites have this , so how it can be done , really i need to know if this machine is running window$ or Linux .

Well i don't know how to delete the post i made this post without thinking a bit more , but i found the solution , as root:

nmap -v -O HOSTNAME .

the machine is running Linux

nmap is a powerful tool , i use it always to detect open and closed ports .

Regards.

I agree. nmap is great. If you like it, you might want to look into Nessus which uses nmap but gives you even more detail.
