|
|
I've got a few Gentoo boxes running @home, a couple that the last sync was done about 4 years ago, and a couple of "fresh" ones.
the old nmap is 5.51, new 6.25 - on some of the systems I use interface aliasses.
here is what I get on 5.51:
Code: | # nmap -e br0:254 -sn 192.168.254.1-254 --system-dns
Starting Nmap 5.51 ( http://nmap.org ) at 2014-10-23 11:59 EDT
Warning: File ./nmap-payloads exists, but Nmap is using /usr/share/nmap/nmap-payloads for security and consistency reasons. set NMAPDIR=. to give priority to files in your local directory (may affect the other data files too).

MAC Address: 00:30:C1:61:7B:AE (Hewlett-packard)
Nmap done: 254 IP addresses (3 hosts up) scanned in 9.03 seconds |
the same on 6.25:
Code: | # nmap -e br0:254 -sn 192.168.254.1-254 --system-dns
Starting Nmap 6.25 ( http://nmap.org ) at 2014-10-23 12:01 EDT
I cannot figure out what source address to use for device br0:254, does it even exist?
QUITTING! |
does the support for iface aliases in nmap have been dropped?
same results after compiling the new nmap on an older (4y) system.
same behavior on the new 'enp' naming scheme.

Why are you using interface aliases? There is no need to use them if you just need multiple IP addresses on a single interface. |

Hi,
For quite a while I use aliases for various reasons. Some apps/scripts require ( or are configured ) an interface to be assigned, not just the ip address the service is listening on, it also keeps IP address <-> interface assignment separate ( more portable and "traditional" ), it is also what I got used to do which does not mean that this is the most efficient and wise thing to do. It surprised me a bit, that the specific interface alias is not handled the same way as it was in earlier versions of nmap - if support for those has been dropped, it might be time to re-think the approach.
Thank you!
