about cache nonexist record

Hello, I have Bind-9.6.1 running on our university environment, have been using dynamic update. My question is, when other DNS query my named for a record, for example test.example.com, but this record doesn't exist. How long time will the remote DNS cache this nonexist record? I found the p

SRV Record Priority set by IP Address

Hello everyone, i've stumbled into a question whether it is possible to configure BIND in a way that it responds to DNS SRV requests with the priority flag changed depending on the IP address of the requesting party. For example, there are two SRV records for _foobar._tcp. One points to 10.0.1.2 a

RE: Bind 9.6.1: skipping zone transfer, but why ?

Hi, I see exactly this problem too on windows 2003. Lookups happen normally after this behaviour occurs though. Restarting bind cures the problem. I haven't bothered to debug the issue as yet :-) Ian -Original Message- From: bind-users-boun...@lists.isc.org [mailto:bind-users-boun..

Re: A smarter stub resolver??

Rather than applying lipstick to the pig, why not run a local caching-only resolver? Move up and out of the stub-ville slums. A local instance of named doesn't take up that much server resources (disk, memory, CPU), and pays you back by *not*, as a stub resolver does, using network resources, a

Problems with EDNS0

Hi list, I have some servers with bind 9.5.0.P2 and one with bind 9.6.1. And the servers logs have a lot of messages with "after disabling EDNS" as seen above: [...] Jul 20 15:31:34 server named[6909]: edns-disabled: info: success resolving 'www.click21.com.br/A' (in 'www.click21.com.br'?) af

RE: A smarter stub resolver??

The problem with this approach is when you are running a couple thousand servers - suddenly, you are running a couple thousand more instances of BIND that need monitoring/patching/care/feeding. A more clever resolver, or a simpler caching setup locally would be ideal. Otherwise, you could redo

Re: Issue with Two Views and Master/SLAVE Servers.

You've got some invalid syntax. Elements in a "masters" clause are separated by semicolons, not just whitespace. I don't believe you can use negation in a "masters" clause either. On the slave side, your main task is to ensure that your outgoing zone-transfer requests are signed with the appro
