# Xymon test to check tftp servwrs
#
# This server script is based on Roland Rosenfeld's conn6 test which
# itself is based on a shell script from the Debian hobbit-plugins
# package, but rewritten in Perl.
#
# Just add tftp to the services of a host and this script will try to
# download the file /pxelinux.0 via TFTP from the given host.
#
# Alternatively you can add colon separated a file or path which
# should be used to test the TFTP server.
#
# Currently only one file per server can be tested.
#
# Examples:
# 10.1.2.3 foo # ftp tftp
# 10.1.2.4 bar # smtp tftp:bootmgr.exe
# 10.1.2.5 baz # tftp:/sparc.img
