AW: (RADIATOR) Putting PostAuthHook script in background.

Fri Feb 13 11:15:04 CST 2004

Hi!

I've implemented a similar scenario (dynamic provisioning) with named
pipes on radiators (high load), so locking/delaying the radiator
processes was a "must not".

Within the init scripts I am starting a process which creates a named
pipe and reads endless from the pipe (blocking if nothing is written to
the pipe). This process handles all the tasks which have to be done (in
my case a perl script - could also be a c executeable or a perl 5.8
multithreaded script ;-) )

In the radiator hook I am writing non-blocked to the pipe (=> very fast
with "no delay"). Problem handling is also quiet easy.

I've played around with executing external commands but I was not happy
about the performance impact (took ~80ms on a Netra with highres logging
to execute a lynx http post as far as I remember). Forking the radiator
process was no issue for me.

At the moment four backend radius processes behind a local proxy on one
machine do the provisioning by this script without problems

Regards,
Rainer

Betreff: (RADIATOR) Putting PostAuthHook script in background.

Hi,

Recently, I realised that when calling an external PostAuthHook perl
script,
radiator waits for the script to finish. Or, if the hook script calls
another perl script to perform some job and if that script, for some
reason,
stalls or waits for an exit, radiator also stalls or freezes.

My question: is there a way I can put the hook script in background? Or
maybe instruct radiator not to wait for the hook script to finish?

TIA.

Regards,
