in reply to My ping should fail but does not

A quick test with pingecho:
$ perl -MNet::Ping -MData::Dumper -e 'my $retval=pingecho("");print Du +mper(\$retval);' $VAR1 = \undef;
shows that if you call pingecho() with an empty host, it returns undef, which should fail your if.
Are you sure that $dbSrvrUNC contains an empty string for the second ping?

[oiskuu]: ... getlogin refers to tty owner; if you close STDIN, then getlogin returns undef. I get undef in my shell (running under X)
[tye]: Then there is a more persistent big of data similar to getlogin(). I don't believe even daemonizing drops it. So you can tell services that were started at boot time from those started by a person.
[tye]: I'll have to look into that later. getlogin() suites my current needs.
