Parallel Network Scanner Description

Parallel Network Scanner provides a fast network services scanner. Parallel Network Scanner provides a fast network services scanner.pnscan is a scanner for TCP network services. It uses multithreading to increase its speed.pnscan tries to be smart as to how many threads to start - it will dynamically start only as many as is needed to make progress in the scan - up to a maximum either as specified with the "-n" command line option, or 8 minus the maximum number of available file descriptors (pnscan tries to increaseit to the max limit automatically) - or any internal limit on the system (Linux normally only allows 256 threads).Host ranges can be specified both as a CIDR - network name or IP address / mask bit length and as a range. When using CIDR notation - the first and last address is ignored (normally used for broadcasts)Some examples:192.168.0.0/24192.160.0.1:192.160.0.254arpanet/8USAGE - EXAMPLES# Scan network 192.168.0.0/24 for SSH daemons on port 22pnscan 192.168.0.0/24 22pnscan 192.168.0.1:192.168.0.254 ssh# Scan hosts 192.168.10.34 ... 98 for IDENT servers, max 8 threadspnscan -n8 -w"VERSION" 192.168.10.34:192.168.10.98 113# Scan host 127.0.0.1 for WWW servers on all portspnscan -w"HEAD / HTTP/1.0rnrn" -r"Server:" 192.168.0.32 1:65525pnscan -w"HEAD / HTTP/1.0rnrn" -r"Server:" localhost 1:65525# Send binary data and expect the binary sequence FF 00 FF on port 145.pnscan -W"05 5A 37" -R"FF 00 FF" 192.168.0.32 145# Scan for Roxen servers and print the whole Server-linepnscan -l -w"HEAD / HTTP/1.0rnrn" -r"Roxen" localhost 1:65525# Scan for pidentd servers and try to locate the versionpnscan -w"VERSION" 192.160.0.0/24 113# Scan network arpanet/24 for daytime servers and sort them IP-numericallypnscan arpanet/10 daytime | ipsort# Read host (&port) lines from stdin and scan the selected hosts for SSHecho '192.160.10.11 ssh' | pnscan -vecho '192.160.10.12' | pnscan 22What's New in This Release:· pnscan.sgml Added the other options implemented in pnscan.c.· pnscan.c: Modified the threads startup code to dynamically only start as many threads as is needed.
