Just registered n-am.ro and nuam.ro domains.
Web sites are ‘parked’ for now until I choose what to put there.
E-mail web access at mail.n-am.ro.
Also, the Start Page at start.n-am.ro, Calendar at calendar.n-am.ro and Docs and Spreadsheets at docs.n-am.ro. For mail, nuam.ro is aliased to n-am.ro.
If you have ideas about web site content or want an e-mail address in these domains let me know 🙂 Same for mumu.ro domain.
DNS hosting kindly provided by EditDNS.
It seems that PowerDNS‘s pdns_recursor crashes on FreeBSD under load.
I’ve replaced it by a bind recursor. Excerpt from named.conf:
options {
directory "/etc/namedb";
pid-file "/var/run/named/pid";
dump-file "/var/dump/named_dump.db";
statistics-file "/var/stats/named.stats";
listen-on port XXXX { 127.0.0.1; };
};
zone "." {
type hint;
file "named.root";
};
It seems that pdns_recursor from 2.9.19 dies under light load on FreeBSD.
New production DNS server is up since Saturday night.
It runs PowerDNS with a MySQL 4.1 backend on FreeBSD 5.4. Complete with web (SSL) administration and statistics.
So far:
Uptime: 18 hours Queries/second, 1, 5, 10 minute averages: 6.4, 5.12, 5.15. Max queries/second: 40.1
Cache hitrate, 1, 5, 10 minute averages: 24%, 22%, 20%
Backend query cache hitrate, 1, 5, 10 minute averages: 63%, 62%, 62%
Backend query load, 1, 5, 10 minute averages: 10, 8.2, 8.59. Max queries/second: 26.7
Total queries: 313999. Question/answer latency: 0.678ms
While searching for a secure DNS server with web administration, run over PowerDNS.
Seems to work fine, no problems noted so far. (Setup: MySQL backend, own pdns_recursor).
PowerDNS has a nice web Operational Monitor:
