.SH NAME
fragtest \- test IP fragment reassembly behaviour
.SH SYNOPSIS
.BI fragtest " TESTS ... host"

to perform them all):
.TP
.B ping
Send an ICMP echo request to the host.
.TP

Send ICMP echo requests with different IP options, to see which IP
options are supported.
.TP
.B frag
Send an ICMP echo request as 8-byte fragments.
.TP
.B frag-new
Send an ICMP echo request as 8-byte fragments with an overlapping
16-byte fragment, favoring newer data in reassembly.
.TP
.B frag-old
Send an ICMP echo request as 8-byte fragments with an overlapping
16-byte fragment, favoring older data in reassembly.
.TP
.B frag-timeout
Send an ICMP echo request as 8-byte fragments, omitting the last
