-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi John,
Interesting indeed. I can see a use for this. How do you initiate the HUP ? Via the radmin tool ?
I know what HUP is :) But thank you for expounding on the history. I was just wondering if there was a way to reload specific virtual server configuration files via the radmin tool, instead of reloading *every* virtual server with a -HUP. I should have been clearer. When some people say 'HUP' they're referring to HUP like behaviour, not actually sending a process the HUP signal.
HUP is a Unix signal, originally meaning "Hang Up" but since has been co-opted to mean "reload your configuration" when the signal is sent to a service (e.g. a daemon). Note, reload is significantly different than restart, during a reload the service continues to run whereas a restart the existing process is terminated and restarted. Unix signal are sent to a process via the kill() function or the kill command (historically signals were often used to kill a process, hence the name, however a better name might be send_signal(), but history lives on).
Thanks, Arran -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAknw9sQACgkQcaklux5oVKLBTACffcErbGJ2oGQb2zmOUGW/0l1c jLoAoI0yQzIL6DDgUBlCzZWk/pfey02P =ikoe -----END PGP SIGNATURE-----
