To Mac-Perl, I've been trying to use the 'ping.pm' module to set up a ping script. The line in this module: $echoport = (getservbyname('echo', 'tcp')) [2]; doesn't return anything on the Mac, but works fine on my DEC. Mac's can reply to ICMP requests, but not send them (yet)? Is this true? Any suggestions? --------------------------------------------------- John Whelan johnw@imagelinc.com
