(RADIATOR) Putting PostAuthHook script in background.

[Ziaur Rahman]

Well, actually I wrote a perl script which updates my DynamicDNS server on
specific users' login and logout. So, based on the Session Status I update
the DNS server (remote). The script does the following things step by step:

1. On every call from PostAuthHook, it connects to a local mysql database to
see if the user is being enabled for DDNS or not.
2. If the user is disabled, it simply quits.
3. If the use is enabled, it checks the Acct-Status-Type attribute supplied
by radiator.
4. If the Acct-Status-Type is Start, it adds the Framed-IP-Address in the
DynamicDNS against the host registered for the user.
5. If the Acct-Status-Type is Stop, it removes the host record for that
spacific user from the DNS.

So, if for any reason, the remote DNS server cannot be reached, radiator
stalls. The irony is, it doesn't even resume operations once the DNS server
is back up. If I could even mention a timeout for the PostAuthHook scripts
response then it would be nice. 

Hope this explains.

Hello Ziaur -

Yes you are correct - Radiator will wait for the PostAuthHook to complete
before continuing.

The correct answer to your question will depend on what else you are doing
and what your exact requirements are.

You may find an AuthBy EXTERNAL clause or even a custom AuthBy clause more
useful. Alternatively you might be able to use a second instance of Radiator
and proxy those requests that need special treatment there.

More details are required before I can suggest anything.

regards

Hugh

NB: have you included a copy of your configuration file (no secrets),
together with a trace 4 debug showing what is happening?
