Hello,I use python-nmap to scan /24 networks sequentially (loop on a networks list). Sometimes it works well : every /24 bloc is scanned successfully. Sometimes the nmap command forked by the python API never exit. The nmap command is the following :
nmap -oX - X.X.X.X/24 -O -sV When I attach an strace on the process I get those messages : epoll_wait(4, {}, 128, 50) = 0ioctl(3, TIOCGPGRP, [0]) = -1 ENOTTY (Inappropriate ioctl for device)
epoll_wait(4, {}, 128, 50) = 0ioctl(3, TIOCGPGRP, [0]) = -1 ENOTTY (Inappropriate ioctl for device)
epoll_wait(4, {}, 128, 50) = 0ioctl(3, TIOCGPGRP, [0]) = -1 ENOTTY (Inappropriate ioctl for device)
Those messages loop forever. Nmap process never exit. Do you have any clue about this problem ? My nmap version : # /usr/local/bin/nmap -V Nmap version 6.46 ( http://nmap.org ) Platform: x86_64-unknown-linux-gnuCompiled with: nmap-liblua-5.2.3 openssl-1.0.1e libpcre-8.30 libpcap-1.3.0 nmap-libdnet-1.12 ipv6
Compiled without: Available nsock engines: epoll poll select My python version : # python3 -V Python 3.2.3 And my python-nmap API is current version 0.3.3 http://xael.org/norman/python/python-nmap/ Regards, -- Nicolas Grenèche URL : http://blog.etcshadow.fr Tel : 01 49 40 40 35 Fax : 01 48 22 81 50 _______________________________________________ Sent through the dev mailing list http://nmap.org/mailman/listinfo/dev Archived at http://seclists.org/nmap-dev/
