Protos – IP Protocol Scanner

Protos is an IP protocol scanner. It goes through all possible IP protocols and uses a negative scan to sort out unsupported protocols which should be reported by the target using ICMP protocol unreachable messages.

First Open Your backtrack and Follow these path

Applications->BackTrack -> Information Gathering -> Network Analysis -> Route Analysis -> protos

 You can start it with./protos –I eth0 –d 192.168.1.2 (IP) -v

Usage: ./protos -i eth0 -d 10.1.2.3 -v

 -v     verbose

 -V    show which protocols are not supported

 -u    don’t ping targets first

 -s     make the scan slow (for very remote devices)

 -L     show the long protocol name and it’s reference (RFC)

 -p x  number of probes (default=5)

 -S x  sleeptime is x (default=1)

 -a x  continue scan afterwards for x seconds (default=3)

 -d dest destination (IP or IP/MASK)

 -i interface         the eth0 stuff

 -W   don’t scan, just print the protocol list
