NAME

fragtest - test IP fragment reassembly behaviour

fragtest TESTS ... host

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.

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