Re: [Users] DNS caching

I second Klaus in this. I might add, it is pretty trivial to set up your 'local' copy of bind9 to timeout within whatever 'acceptable' period you so desire (i.e., so as to prevent 'INVITE hangs', etc.). cheers ----- Original Message ----- From: Klaus Darilion &lt;klaus.mailinglists(a)pernau.at&gt; To: Christian Schlatter &lt;cs(a)unc.edu&gt; Cc: users(a)openser.org Sent: Monday, February 12, 2007 2:40:59 PM GMT-0600 Subject: Re: [Users] DNS caching I wonder why you need DNs caching inside openser. Usually you will a resolving name server near (in terms of network hops) to your SIP proxy. E.g. I have a bind9 running on the same linux box as openser. This name server will be used by all processes running on this linux box (/etc/resolv.conf points to 127.0.0.1 and to another name server in my server farm). Bind will cache all requests. A request for a domain which is cached in bind will usually be <1ms and during waiting for the DNS response openser wont cause CPU load - and probably the caching implementation in bind is a good one. Thus for me I do not see any reason for having the caching inside the SIP proxy. regards klaus On Mon, February 12, 2007 20:22, Christian Schlatter said: _______________________________________________ Users mailing list Users(a)openser.org http://openser.org/cgi-bin/mailman/listinfo/users
