Since I switched to the kernel pppoe I receive a lot errors with nmap. "Cannot determine route to %FOO".
For example with a bank-website: lynx www.cc-bank.de works perfectly nmap -P0 -sSV -p80 www.cc-bank.de does not work. nslookup www.cc-bank.de does work so it`s realy a neat routing issue. Another example with www.heise.de: sudo nmap -P0 -sS -sV -vvv www.heise.de Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2006-07-13 17:52 CEST WARNING: Unable to find appropriate interface for system route to 0.0.0.1 WARNING: Unable to find appropriate interface for system route to 0.0.0.0 nexthost: failed to determine route to 193.99.144.85 QUITTING! Please don`t get me wrong I just needed some Servers where I`m sure they where working. I tried it also with -e pppoe0 and later with fxp0 (wich failed, no Adress). godfather $ sudo nmap -e pppoe0 -P0 -sSV -p22,80 -vvv www.heise.de Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2006-07-13 17:58 CEST WARNING: Unable to find appropriate interface for system route to 0.0.0.1 WARNING: Unable to find appropriate interface for system route to 0.0.0.0 DNS resolution of 1 IPs took 0.04s.

It doesn`t matter wich IP I scan even if I would scan www.hotmail.com with Port 80 it would tell me it`s filtered. I`ve NO active pf and the only stuff I made was switching from userland pppd to Kernel pppd. Any hints to make nmap working? Kind regards, Sebastian p.s. OpenBSD AMD64/3.9-Stable with a current nmap-Port. (same result with 3.95 so doesn`t matter)
