after searching through a text file of IP's, trying to figure out what on earth the invalid character could possibly be... I realized it's because I specified more than 4098 hosts. nmap -n -sL -iL master.txt | wc -l Invalid character in host specification. QUITTING! 4098
No - Nmap should have no such arbitrary limit. Here I generate and then (list) scan a list of 50,000 IPs: # nmap -sL -iR 50000 -n -oG- | egrep "^Host " | cut "-d " -f2 > 50kIPs.txt # nmap -n -sL -iL 50kIPs.txt |& tail -1 Nmap run completed -- 50000 IP addresses (0 hosts up) scanned in 0.388 seconds Also, what version of Nmap are you using? I think that error message was changed a long time (years?) ago. Try with Nmap 3.81, and if you still have the problem, check your file closely for invalid (non IP address or hostname) characters. In particular, look at the last host shown and then check the next few dozen in the file. If all looks well, you can send me your master.txt and I'll look at it.
