Hi Guys,

Hope you can help me,

I got lab setup with BT5 & Installed De-Ice.net 192.168.1.100 (first series).

It seems by default it is set up with 192.168.100.1, my router asusual has 192.168.0.x. I'm not able to ping to De-Ice distro....

My question is without logging into De-Ice i cannot change the ipaddress....Similarly I tried changing ipaddress in my router for 192.168.1.x series to enable to connect accordingly.....Seems I'm missing something & not sure how to overcome the situation....
Your help is much appreciated...

Cheers

I would think that changing the subnet on your router to 192.168.1.x would work, that's exactly what I had to do...hmm.  Make sure your not testing connectivity to the .1.100 De-ICE disc via ping - it won't reply.  You can test by trying to FTP or SSH to it (should get a login prompt).

Hi Hayabusa

I got my Lab setup in Mac.....I believe Mac version of VM (vm fusion) available only in trial version....(else got to buy it)....

Any other option.....?

ha this just happened to me the other day as well... probably a good year since i've played with it (forgetting of course it can't be pinged).... 5 minutes later.... OH YEAH CRAP

I remember there being a wiki or forum entry about it not being pingable though you are right in saying that it is extremely difficult to find.

I designed the De-ICE disks to imitate the real world, and one thing I always did as a sysadmin was turn off things like ping... So, I did the same with the 1.100 disk. The educational purpose behind turning it off was to teach people to use multiple tools to validate everything they do. As my students hear me say (too frequently), "always be cynical and use more than one tool for each task."

Just to make sure we're all on the same page:

• The router is configured to use the 192.168.1.x subnet
• The BackTrack VM is configured for bridged networking
• The BackTrack VM has an IP address in the 192.168.1.x subnet (a DHCP addresses leased from the router?)
• The De-ICE 1.100 disc is configured for bridged networking
• You can see the De-ICE .1.100 disc from the BackTrack VM using netdiscover
• You can't get a list of open ports when you scan the De-ICE .1.100 disc using nmap

What's the nmap command you are using?

I'm slightly confused as to the router configuration.  What kind of router is it - wireless router?  A DHCP server is functionality found on most consumer routers now days.  The service will lease IP addresses to other devices that connect to it.  Usually the IP address you configure for the router will reside on the same subnet that it leases IP addresses for.  For example, if you configure the router to have an IP address of 192.168.1.1, the DHCP service will lease addresses on the 192.168.1.x subnet (e.g. 192.168.1.10, 192.168.1.11, etc).  Here's a screenshot of the configuration page for my router (Linksys WRT54G2) where I define the local router IP.  You can see that it auto-filled the 3rd octet with "1" so that the IP addresses it leases are on the same network as the router itself.



It looks like your router is still configured for the default 192.168.0.x subnet and the BT VM is getting a DHCP IP addresses from the router for that same 192.168.0.x subnet.  Since the De-ICE disc has a static IP address of 192.168.1.100 while the BT VM and router are on the 192.168.0.x subnet, there's no route from the BT VM to the router to the De-ICE VM.  I think as soon as you get the router configured for the 192.168.1.x subnet and make it so that the DHCP server on the router leases IP's on the same 192.168.1.x subnet, you should be good to go.

As for why your BT VM is finding the De-ICE disc using netdiscover...since netdiscover uses ARP to discover devices, my guess is that the BT VM is picking up the ARP traffic that's being broadcast by the De-ICE disc.
