Currently I'm parallelizing scans by using a bash script like the one attached. It starts nmap in background, waits for all scans to complete and sends the summarized results to a specified email address.
I never scan more than 10 or 15 hosts at a time (and use a very old version of nmap :) so this is most likely not a convenient way to scan 100+ hosts but I hope it is helpful to someone until parallel scanning is implemented.
#!/bin/bash # hosts to scan hosts=( host1 host2 host3 ) # clean up old scan results rm nmap.* 2>/dev/null # launch scans in background for host in ${hosts[@]} do nmap -v -sS -O $host >nmap.$host & # with errors #nmap -v -sS -O $host >nmap.$host 2>nmap.$host.err & echo "starting scan for $host" done # wait for their completion wait # summarize results grep 'Interesting ports on\|scanned but not shown below\| open \| closed \| filtered ' nmap.* >nmap.__results # shorter summary: #grep 'tcp \|udp ' nmap.* >nmap.__results # this may be more suitable when focusing on OS detection: #grep 'Interesting ports on\|OS details\|Running\|Device type' nmap.* >nmap.__results # pack 'em together tar -cjf nmap.tar.bz2 nmap.* # mail me my results + summary # NOTE: biabam.nmap is a slightly modified version of the biabam # bash attachment mailer that does not prompt for a message body! biabam.nmap nmap.tar.bz2 -s 'NMAP run complete!!' root () servers lan
