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.
