ssh, ldap, resolving

If you're using LDAP with those options in /etc/conf.d/slapd

OPTS="-h 'ldap://127.0.0.1 ldaps://foo.bar.tld:23523'"

a missconfigured /etc/resolv.conf could be fatal. Your slapd would not run and die with

slapd[12876]: daemon: getaddrinfo() failed: Temporary failure in name resolution

A possible solution is to resolve your hostname yourself. Just put a $IP $HOSTNAME of yourself in the /etc/hosts. That should be very safe.

Another point is that if your name resolution is broken ssh will have got problems with local users if it cannot reach the ldap daemon because it is down.

Connection closed by remote host

This only happens if you send a public key to authorize yourself. To fix this issue try to don't send any public key

ssh foo.bar.tld -l localuser -o PubkeyAuthentication=no

Thanks to KillerFox for reproducing these things.

!.png Hardware failure of nanofortnight

Almost one week ago we've got a hardware failure on nanofortnight. One heat sink lost contact. Now we tried a little bit of thermal grease to fix it. After a downtime to cool down we've got problems with almost all of our services.
The problem was based upon the fact that we replaced dnscache with the nameservers of our provider.
But we forget that /etc/resolv.conf is overwritten with the config of /etc/conf.d/net on startup. So everything couldn't be resolved at this time anymore.

Today I was at the data center and fixed it myself. Everything should be up, running and just fine. Sorry for any inconviences. If you still notice some strange things, please report it.
At the end I want to thank again the team of mammutware for the great support.

Yesterday I found an interesting link on Netzpolitik about 19 Mashups of the year 2007. They made a musical review of the last year. It's somehow really cool.

iPhone

Yesterday I saw the guided tours of the iPhone. It is really amazing what this gadget can. It is a better iPod touch. It is so easily usable. The master feature I noticed was the possibility to surf the net via Wi-Fi.

The marketing of the iPhone is just incredible as the product itself.
