PowerDNS recursor problems

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";
};

Opensource PDC

The fourth opensource PDC (Primary Domain Controller) using samba, with a openldap backend for storing users, groups and computers. It can replace a Microsoft Windows Domain Controller.

Provides central authentication services, file and printer sharing for Windows and Unix clients. Local logon credentials are taken from LDAP, too.

Tested on fedora core 4 and slackware 10.2.

Asus WL-500g

Just got two Asus WL-500g!

New DNS server up

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

Bad news on Linksys WRT54g v5

WRT54gG v5 does not work with custom firmares! :-(

I think this is a bad move from Linksys/Cisco as most of the pieces sold were used with custom firware.
Need to use other wireless routers, such as Asus, Netgear.

Some alternatives in my wiki.

FreeBSD / D-Link IPSEC problems

No luck in IPSEC between a FreeBSD 5.4 (racoon) and a D-Link DI-804HV :-(

Tried manual and IKE, SAs up but no traffic through the gif device. Perhaps D-Link could add more troubleshooting functions into their firmware (e.g. show routing table, SAs, disable NAT, routes through PPTP or L2TP tunnels).

PowerDNS

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:
