If I sum up: - on Perl 5.005_03 / Solaris 8: - setlogsock("unix", "/dev/console") => works - setlogsock("stream") => complains but works - on Perl 5.8.4 / Solaris 10: - setlogsock("unix", "/dev/console") => works - setlogsock("stream") => doesn't work I guess you're using the versions shipped with their respective Perl distribution, which means a version so old it wasn't even numbered in Perl 5.005_03, and version 0.05 in Perl 5.8.4. The behaviour on Perl 5.005_03 / Solaris 8 is normal: "stream" wasn't a supported mechanism at that time, so setlogsock() complains and defaults on "unix". The behaviour on Perl 5.8.4 / Solaris 10 make come from an incompatible change in Solaris itself. As noted in the comments, the "stream" mechanism is a little dodgy: # XXX: this only works if the OS stream implementation makes a write # look like a putmsg() with simple header. For instance it works on # Solaris 8 but not Solaris 7. # To be correct, it should use a STREAMS API, but perl doesn't have one. I don't know if Sun kept this in Solaris 10. A simple solution is to upgrade to a recent Sys::Syslog, which now have support for true native syslog(3), using the actual C functions. It's also the default mechanism so you don't need to specify it with setlogsock() (in fact, using this function is now strongly discouraged). With this, your Perl programs will behave exactly like any other program sending message to the syslog subsystem, easing further dispatching from within the daemon. -- Sébastien Aperghis-Tramoni Close the world, txEn eht nepO.

You should have nothing to change except removing the setlogsock() calls. Sys::Syslog will by default use the native syslog(3) mechanism. If you have a problem, don't hesistate to mail me through this ticket. -- Sébastien Aperghis-Tramoni Close the world, txEn eht nepO.

No: since version 0.16, the default mechanisme for sending message to syslog is to use the "native" one, calling the POSIX functions syslog (3). ("native" is probably not a very good name but I didn't have a better one, and "unix" was already taken.) The general rule is to avoid calling setlogsock() so Sys::Syslog can select the best default mechanism: "native" on Unix, "eventlog" on Win32. -- Sébastien Aperghis-Tramoni Close the world, txEn eht nepO.
