Creating /dev/lo0 on 10.20

[HPP]

Hi,
Can anyone tell how to create /dev/lo0. i am trying to run "nmap" and it reports /dev/lo0 not available. I tried to create /dev/lo0 using "cd /dev; mknod lo0", but it is not creating.

Thanks

What is nmap ??

Do the command> netstat -r

You will see an interface called lo0 already exists (but not a device file for it - its a logical name for local loopback). You should not try to create a /dev/lo0. I think your nmap program/app should be reconfigured to point to /dev/lanX (eg. lan0) instead of lo0.

Stefan Farrelly,
Thanks much for your response. I feel lo0 is the loopback Interface. "nmap" is used for Network exploration tool and security scanner
check this URL:

&

Now question is how should i create /dev/lo0 for loopback interface on 10.20?

Thanks

Padmanabha,

I've not been able to unearth any more details on /dev/lo0. There is no mention of it in the HPUX documentation LLA Programmers and DLPI Programmers guides at http://docs.hp.com . I suspect this is because the local route thru all local lans goes via loopback.

Because of this info, and what you've discovered so far, I recommend checking with the authors of nmap, per http://hpux.cs.utah.edu/hppd/hpux/Networking/Admin/nmap-2.53/

If you get an answer or a solution, please let the rest of us know. Thanks!!

I've just been caught by this as well. I don't have any solution to it but it seems as though it only happens when you try and scan the localhost.
