I work for a small business and outsourced our email hosting to Google. However, I noticed that spammers are using our From: First Last to send their spam messages. All bounced messages come to our catch only account. How do I stop this? How do I validate our domain using SPF? How do I configure a SPF for Google Apps domain using BIND 9 or djbdns?
The rndc stats commands created /var/named/chroot/var/named/data/named_stats.txt file under RHEL 5.x or CentOS 5.x BIND 9 server. However, date is not is correct format. The date is in the following format:
grep ‘Dump’ /var/named/chroot/var/named/data/named_stats.txt
+++ Statistics Dump +++ (1263408025)
— Statistics Dump — (1263408025)
+++ Statistics Dump +++ (1263408071)
— Statistics Dump — (1263408071)
+++ Statistics Dump +++ (1268304218)
— Statistics Dump — (1268304218)
+++ Statistics Dump +++ (1268304248)
— Statistics Dump — (1268304248)
How do I convert date (e.g., 1263408025) in a human readable format?
BIND9 dynamic updates allow remote servers to add, delete, or modify any entries in my zone file. How do I disable dynamic updates under BIND 9 (named) for any zone?
How do I configure Bind 9 dns server views to allow a single nameserver in my DMZ to make different sets of data available to different sets of clients? For example, I’d like to run recursion, some other data for LAN users (192.168.1.0/24), and for the Internet user I’d like to display limited DNS data without recursion. How do I configure views to partition external (Internet) and internal (LAN) DNS information?
Q. I’ve configured BIND named TSIG as documented here. It worked for some time, but my /var/log/messages got the errors as follows:
zone example.org/IN: refresh: failure trying master 22.214.171.124#53 (source 0.0.0.0#0): clocks are unsynchronized: 9 Time(s)
zone example.org/IN: refresh: failure trying master 126.96.36.199#53 (source 188.8.131.52#0): clocks are unsynchronized: 9 Time(s)
How do I fix these errors under Debian Linux 64 bit etch server?
Q. How do I stop recursion (recursive query) under BIND 9 DNS server?
