machine on my broadcast ip
I take care of a small network, about 130 systems behind a NAT box. This is one
of 2 networks at this school. It is of constant concern about interference from the other
2 of my main feeds go through their network. I am "not allowed" access or control of these feeds.
For a little while I have had strange effects in the network and then while doing a full nmap, I
discover a system on my broadcast IP. ( x.y.z.255 ) The OS is not identified. It says :
nmap -sS -O x.y.z.255
Starting nmap 3.81 ( Nmap - Free Security Scanner For Network Exploration & Security Audits. ) at 2009-06-09 16:39 EDT
Host x.y.z.255 seems to be a subnet broadcast address (returned 10 extra pings). Still scanning it due to ping response from its own IP.
Interesting ports on x.y.z.255:
(The 1660 ports scanned but not shown below are in state: closed)
PORT STATE SERVICE
23/tcp open telnet
80/tcp open http
443/tcp open https
MAC Address: 00:14:BF:5F:A9:29 (Unknown)
No exact OS matches for host (If you know what OS is running on it, see Nmap Fingerprint Submitter 2.0).
Nmap finished: 1 IP address (1 host up) scanned in 25.401 seconds
I can't telnet or connect by browser because " Network is unreachable "
Is there any methods or tests to find out more about this machine?
