lost9999 Posted February 28, 2008 Share Posted February 28, 2008 Hi, I am a new SysAdmin and I was overhauling the DHCP. Im having trouble finding out what computer is at (192.168.1.5) on my internal network. I pinged it and got a reply. Is there an easy way I can find out what computers are associated with which IP address? DHCP only shows me reservations and leases. Its not in either.Help!

cluberti Posted February 29, 2008 Share Posted February 29, 2008 If it's in DNS, you could do a ping -a 192.168.1.5. Otherwise, you'll want to use a network scanner to do some sniffing of the box to see what secrets it reveals. Link to comment Share on other sites More sharing options...
FAT64 Posted February 29, 2008 Share Posted February 29, 2008 Could you not just use Remote Desktop and then right-click My Computer > Properties > Computer Name. Link to comment Share on other sites More sharing options...
rendrag Posted February 29, 2008 Share Posted February 29, 2008 Could you not just use Remote Desktop and then right-click My Computer > Properties > Computer Name. that assumes it's a PC, and assumes it accepts remote desktop sessions. Link to comment Share on other sites More sharing options...
lost9999 Posted February 29, 2008 Author Share Posted February 29, 2008 Could you not just use Remote Desktop and then right-click My Computer > Properties > Computer Name. I loved this idea! It didnt work though... It may not be setup for remote (as stated in later post). The ping option didnt work either. I appreciate the options, anymore?

I really loved that idea too! The ping suggestion didnt work either. We have over 100+ devices on the network so going from pc to pc doenst sound like a blast Any other suggestions?

cheezewizz247 Posted February 29, 2008 Share Posted February 29, 2008 Is there no Windows equivalent of the nmblookup you get on Linux, if not then a liveCD and going to a console and doing 'nmblookup -SA 192.168.1.5' may do it........ Link to comment Share on other sites More sharing options...
cluberti Posted February 29, 2008 Share Posted February 29, 2008 There isn't an equivalent - nbtstat is very limited in Windows compared to nmblookup on *nix hosts. However, I still suggest a network scan of that IP to see what it reports, if anything. Link to comment Share on other sites More sharing options...

Ponch Posted February 29, 2008 Share Posted February 29, 2008 Type the adress in a browser, you might get a page if it's a printer. Just an other idea. Link to comment Share on other sites More sharing options...
ringfinger Posted February 29, 2008 Share Posted February 29, 2008 Do a port scan and see whats open. Try to unc from the run line and look at the hidden c share if its a windows box. Is it in the same layer 2 network or is there a gateway between you? If L2, ping it, that'll add an arp entry to you're machine, issues the arp -a command to view the MAC, then use your network equip to find the device by MAC. If over L3, do a tracert and narrow down which hops it uses. Link to comment Share on other sites More sharing options...
cluberti Posted February 29, 2008 Share Posted February 29, 2008 How do I do a network scan?When I'm stuck on a windows box to do these sorts of things, I like using this particular scanner. Link to comment Share on other sites More sharing options...
eyeball Posted March 1, 2008 Share Posted March 1, 2008 (edited) at cmd type nslookuptype set q=ptrtype 192.168.1.5theres your answer hopefullyEDIT: sorry i overlooked the fact that a ping -a didnt resolve it. maybe try telnet to the IP?

cluberti Posted March 1, 2008 Share Posted March 1, 2008 at cmd type nslookuptype set q=ptrtype 192.168.1.5theres your answer hopefullyping -a does do a ptr lookup on the IP address. He stated that didn't work, hence 192.168.1.5 doesn't have a ptr (or a forward A) record. Link to comment Share on other sites More sharing options...
