Identify unknown LAN server from IP or MAC address
Hi,
I just got a little task trying to seemingly find a needle in a haystack.
I have a server (FreeBSD) where several NFS mounts are established from a host somewhere on the local LAN with the 192.168.x.x prefix.
Needless to say, the guy who set this up wasn't too fond of documenting his work apart from the "# NFS" comment in the fstab. I can see that the server that I am on also has set up an interface with a 192.168.x.x address, which natually doesn't help me much other than it looks like a trend. There is no documentation on the LAN addresses end points anywhere to be found.
My question is, is there anyway I could try to identify what the server's hostname is (if any)? I tried nslook, arp, ping, ssh, telnet (both telnet+ssh denied, probably firewall), netstat (it's used as a static route as well), anything that I could think of a late Saturday evening.
I have the aforementioned IP address and I have the MAC address, but my network knowledge is a bit on the wee side to put the nail in the coffin :-)
Some could argue - log on to the servers and check their interfaces - but there's FAR too many for comfort :-(
I hope you can throw me a pointer or two.
