I work as a consultant for a company that has several educations, and their main fileserver runs MacOSX server. Since i started there (Fall 2001) I have restarted that MacOSX server once. So for me, there has been no problem at all. But still I feel that Apple needs to seriosly educate their support. Many of them doesn't know anything about Apple's products.

Let's get a .mac top level domain! As in www.xyz.mac

ICANN, the Internet Corporation for Assigned Names and Numbers, is inviting proposals for new sponsored top level domains. This may be wishful thinking, but isn't that a chance to push for a .mac top level domain (TLD)? I for one would VASTLY like the idea of having a domain of something.mac --... (0 Replies)

NAME
Log::Log4perl::Appender::Socket - Log to a socket SYNOPSIS
use Log::Log4perl::Appender::Socket; my $appender = Log::Log4perl::Appender::Socket->new( PeerAddr => "server.foo.com", PeerPort => 1234, ); $appender->log(message => "Log me "); DESCRIPTION
This is a simple appender for writing to a socket. It relies on IO::Socket::INET and offers all parameters this module offers. Upon destruction of the object, pending messages will be flushed and the socket will be closed. If the appender cannot contact the server during the initialization phase (while running the constructor "new"), it will "die()". If the appender fails to log a message because the socket's "send()" method fails (most likely because the server went down), it will try to reconnect once. If it succeeds, the message will be sent. If the reconnect fails, a warning is sent to STDERR and the "log()" method returns, discarding the message. If the option "silent_recovery" is given to the constructor and set to a true value, the behaviour is different: If the socket connection can't be established at initialization time, a single warning is issued. Every log attempt will then try to establish the connection and discard the message silently if it fails. If you don't even want the warning, set the "no_warning" option to a true value. Connecting at initialization time may not be the best option when running under Apache1 Apache2/prefork, because the parent process creates the socket and the connections are shared among the forked children--all the children writing to the same socket could intermingle messages. So instead of that, you can use "defer_connection" which will put off making the connection until the first log message is sent. EXAMPLE
Write a server quickly using the IO::Socket::INET module: use IO::Socket::INET; my $sock = IO::Socket::INET->new( Listen => 5, LocalAddr => 'localhost', LocalPort => 12345, Proto => 'tcp'); while(my $client = $sock->accept()) { print "Client connected "; while(<$client>) { print "$_ "; } } Start it and then run the following script as a client: use Log::Log4perl qw(:easy); my $conf = q{ log4perl.category = WARN, Socket log4perl.appender.Socket = Log::Log4perl::Appender::Socket log4perl.appender.Socket.PeerAddr = localhost log4perl.appender.Socket.PeerPort = 12345 log4perl.appender.Socket.layout = SimpleLayout }; Log::Log4perl->init($conf); sleep(2); for(1..10) { ERROR("Quack!"); sleep(5); } COPYRIGHT AND LICENSE
