[stunnel-users] FQDN validation and checking within

Tue Jan 31 18:14:44 CET 2006

Mike:

Given this: what is the best way for Stunnel to make authentication
And authorization decisions based on information presented in the
Certificate from the peer. My question comes from: how do I do level 3
Checking in a scalable manner when my order of magnitude is in the 
Thousands...

Much thanks

Sekhar

DNS is not a secure protocol
(http://www.securesphere.net/download/papers/dnsspoof.htm).  Security
should not be based on DNS checks.  I'm not going to implement this
feature.

Best regards,

Are we still talking about IRIX?
http://nixdoc.net/man-pages/IRIX/man3c/makecontext.3c.html
I can't find any of mentioned limitations in the manual.
Just the opposite: "the arguments that follow the argc parameter for
makecontext are restricted to longs and pointers only".

Best regards,
    Mike
