IO::Socket::INET sets $@, not $! I'm looking at IO::Socket::INET.pm, and it certainly does set $! under some circumstances, though it goes to great lengths to maintain $!, meaning that a previous value in $! can propogate through to snag the unwary. Here's a simple way to duplicate the symptoms: `use IO::Socket::INET; open(F, "<", "nosuchfile"); # set $! my $socket = new IO::Socket::INET(); print "$!"; # prints "No such file or directory"` [download]	[reply] [d/l]
