 - create the version of the script for this host as "tmp.pl"
 - scp tmp.pl remote.host:/your/path/tmp.pl
 - ssh remote.host /your/path/tmp.pl /etc/sysconfig/netdump
 - for neatness, tmp.pl could include a third line (after the shebang
    and the s/.../.../):

      END { unlink /your/path/tmp.pl }
