    Are you invoking Sys::Syslog's setlogsock? If not, according to
    the perldoc, the module will try to connect to syslogd with these
    protocols, in this order: tcp, udp, unix, stream, console.

    TCP will probably fail. UDP might succeed, perhaps depending on
    your configuration. The UNIX socket should succeed, unless the
    mode of the socket in /dev or whever AIX keeps it is too restrictive
    for the uid under which your perl process runs. Be sure to check
    the mode of that file.
