Q: Why doesn't -u work on Linux 2.2.x when I build with --enable-threads?
|
||||
@ -630,3 +634,42 @@ A: Red Hat Security Enhanced Linux (SELinux) policy security protections :

Q: I want to forward all DNS queries from my caching nameserver to another server.
|
||||
But there are some domains which have to be served locally, via rbldnsd.
|
||||
|
||||
How do I achieve this ?
|
||||
|
||||
A: options {
|
||||
forward only;
|
||||
forwarders { <ip.of.primary.nameserver>; };
|
||||
};
|
||||
|
||||
zone "sbl-xbl.spamhaus.org" {
|
||||
type forward; forward only;
|
||||
forwarders { <ip.of.rbldns.server> port 530; };
|
||||
};
|
||||
|
||||
zone "list.dsbl.org" {
|
||||
type forward; forward only;
|
||||
forwarders { <ip.of.rbldns.server> port 530; };
|

};
|
||||
|
||||
|
||||
Q: Will named be affected by the 2007 changes to daylight savings rules in the US.
|
||||
|
||||
A: No, so long as the machines internal clock (as reported by "date -u") remains
|
||||
at UTC. The only visible change if you fail to upgrade your OS, if you are in a
|
||||
affected area, will be that log messages will be a hour out during the period
|
||||
where the old rules do not match the new rules.
|
||||
|
||||
For most OS's this change just means that you need to update the conversion
|
||||
rules from UTC to local time. Normally this involves updating a file in /etc
|
||||
(which sets the default timezone for the machine) and possibly a directory
|
||||
which has all the conversion rules for the world (e.g. /usr/share/zoneinfo).
|
||||
When updating the OS do not forget to update any chroot areas as well. See your
|
||||
OS's documetation for more details.
|
||||
|
||||
The local timezone conversion rules can also be done on a individual basis by
|
||||
setting the TZ envirionment variable appropriately. See your OS's documentation
|
||||
for more details.
