I’m stuck on a lab for Nmap’s Firewall and IDS/IPS Evasion, any help would be appreciated.
I’m trying to spoof the scan’s source IP address, just as it’s discussed in the module, and I keep getting the nmap error “failed to determine route”
Here is my scan and result:
$ sudo nmap 10.129.208.213 -n -Pn -O -S 10.129.208.200 -e tun0 Starting Nmap 7.92 ( https://nmap.org ) at 2022-03-24 08:12 GMT setup_target: failed to determine route to 10.129.208.213 WARNING: No targets were specified, so 0 hosts scanned. Nmap done: 0 IP addresses (0 hosts up) scanned in 0.21 seconds
I’m guessing the issue has to do with the interface I’ve specified with the
-e flag, however I’ve tried all available interfaces (
eth1) and all produce the same result. What am I doing wrong? Thanks for any help.
Note: I can scan the address
10.129.208.213 just fine, but whenever I use the
-S to spoof I get this error
