I wrote about running unbound and nsd on OpenBSD 5.6 here .
The other day, the VM that runs those went to DDB. On reboot, I got the following error message :
unbound: [16897:0] error: ldns error while converting string to RR at15: Syntax error, could not parse the RR's type: spamd: \\[priv\\] unbound: [16897:0] error: failed to load trust anchor from /db/root.key at line 1, skipping unbound: [16897:0] error: failed to read /db/root.key unbound: [16897:0] error: error reading auto-trust-anchor-file: /var/unbound/db/root.key This means “root.key” went broken.

Quoting its website : iRedMail is a ZERO COST, full-featured, Open Source Email Server Solution released under GPLv2. Woaw… You saw that great fireworks and garland lights… Just kidding. Now, let’s see what you get.Continue reading...
OpenBSD ships with an LDAP daemon since 4.8. I have an all-in-one server from which the LDAP service has to be shipped out. I’m going to replace that OpenLDAP daemon with the LDAP daemon from OpenBSD 5.1. I already wrote about how to enable LDAP on OpenBSD 4.8 .
Those will be updated notes for OpenBSD 5.1 and additional directions to allow monitoring the LDAP activity using SNMP and Xymon server.Continue reading...
