BackTrack5r3中执行nmap时提示invalid bpf filter

Hello,

I want to do a TCP idle scan with metasploit&nmap

But I keep having a problem with Metasploit.Here is what I do and the error I get.

msf>use auxiliary/scanner/ip/ipidseq

msfauxiliary(ipidseq)>set RHOSTS 192.168.1.0/24

RHOSTS=>192.168.1.0/24

msfauxiliary(ipidseq)>set THREADS 50

THREADS=>50

msfauxiliary(ipidseq)>run

At this point I have no clue what to do.I have searched for a solution for two hours straight now and found nothing.

Thanks a head of time.

Your network device is set to usb mon1,shouldn't it be eth0 or wlan0 depending on network/wifinetwork?

Do a "show options".You probably need"set interface eth0"or somethings imilar like eth*.
