NAME

       fragtest - test IP fragment reassembly behaviour

SYNOPSIS

       fragtest TESTS ... host

DESCRIPTION

       fragtest   probes  the  remote  host  to  determine  its  TCP/IP  stack
       behaviour.

       The TESTS may include any of the following (or may be specified as  all
       to perform them all):

       ping   Send an ICMP echo request to the host.

       ip-opt Send  ICMP echo requests with different IP options, to see which
              IP options are supported.

       frag   Send an ICMP echo request as 8-byte fragments.

       frag-new
              Send  an  ICMP  echo  request  as  8-byte  fragments   with   an
              overlapping 16-byte fragment, favoring newer data in reassembly.

       frag-old
              Send  an  ICMP  echo  request  as  8-byte  fragments   with   an
              overlapping 16-byte fragment, favoring older data in reassembly.

       frag-timeout
              Send an ICMP echo request as 8-byte fragments, omitting the last
              fragment,  and  wait  for  an  ICMP  time-exceeded-in-reassembly
              reply.

BUGS

       Firewalls or other filtering network devices may  block  IP  fragments,
       packets with IP options, ICMP echo traffic, etc.
