Editing HowTo's (section)

==== Solved ====
===== datum =====
date +%Y%m%d%T -s "20111120 13:31:00"
===== Netwerk domU =====
De netwerkinterface van de domU werkt niet op de Intel machine. De vpn-router werkt wel, maar de toegevoegde machines niet.

De interface op de dom0 in /etc/network/interfaces moeten de naam xen-brx krijgen scripts gaan analoog.

===== xm console werkt niet op de Intel machine =====

Het opstarten van het console blijft steken.

Oplossing:
Lenny xen werkt met een andere console definitie. Toevoegen in de <domain>.cfg:
 extra       = 'console=hvc0 xencons=tty'

===== apt key update =====
apt-get update levert een error op: 
 W: GPG error: http://mirror.webhuis.nl etch Release: The following signatures couldn't be verified because
 the public key is not available:  NO_PUBKEY 9AA38DCD55BE302B
 W: GPG error: http://mirror.webhuis.nl etch/updates Release: The following signatures couldn't be verified because
 the public key is not available: NO_PUBKEY 9AA38DCD55BE302B
 W: You may want to run apt-get update to correct these problems
Oplossing:
 gpg --keyserver keys.gnupg.net --recv 9AA38DCD55BE302B
 gpg --export --armor 9AA38DCD55BE302B | apt-key add -

===== apt InRelease update =====
apt-get update levert een error op: 
N: Repository 'http://ftp.uk.debian.org/debian buster InRelease' changed its 'Version' value from '10.19' to '10.13'           
E: Repository 'http://ftp.uk.debian.org/debian buster InRelease' changed its 'Suite' value from 'stable' to 'oldstable'
Oplossing:
# apt-get update --allow-releaseinfo-change
===== subversion =====
Localtime is gewijzigd van file naar symbolic link, dat resulteert in de volgende fout:
 # cfengine2:/var/backups/cfengine2# svn commit -m "handmatig 20090921"
 svn: Commit failed (details follow):
 svn: Entry '/var/backups/cfengine2/etc/localtime' has unexpectedly changed special status
Oplossing:
 # cfengine2:/var/backups/cfengine2# svn pd svn:special etc/localtime
 property 'svn:special' deleted from 'etc/localtime'.
 # cfengine2:/var/backups/cfengine2# svn rm etc/localtime
 D         etc/localtime 
 # cfengine2:/var/backups/cfengine2# svn commit -m "handmatig 20090921"

===== TLS bij ldap =====

 http://rustykruffle.com/tech-stuff/ubuntu/ultimate-home-server-ldap-gnutls-nightmare/

try

 ldd $(which slapd)

you may see, that slapd is build with gnutls and not openssl :-)

You have two different solutions to fix this:

1. use the tool certtool from gnutls in package gnutls-bin. doc is in 
gnutls-doc or use the doc from the qemu/kvm packages and look their for 
vnc.

2. create a copy of /etc/ssl/certs/cacert.pem and reorder your 
certificates. gnutls expects just the opposite order as openssl :-(

De oplossing:
    - Comment out TLSCipherSuite settings on upgrade from all versions prior
      to 2.4.7-5, and throw a debconf error to the user notifying them of
      this, since all OpenSSL cipher suite values are incompatible with
      GnuTLS.
===== Clock =====
Problem
 domU verzuipt in clocksource meldingen en is niet responsief.
Workaround
In your domU /etc/sysctl.conf add the line:
 xen.independent_wallclock=1.
On the dom0, edit the configuration file of the domU (e.g. /etc/xen/foobar.cfg and add (or expand) the extra-line:
 extra="clocksource=jiffies".
These settings can be activated without rebooting the domU. After editing the configuration files, issue
 # sysctl -p and echo "jiffies"> /sys/devices/system/clocksource/clocksource0/current_clocksource
on the domU prompt.
 # sysctl -p
 # echo "jiffies"> /sys/devices/system/clocksource/clocksource0/current_clocksource
Because the clock won't be relying on the dom0 clock anymore, you probably need to use ntp on the domU to synchronize it properly to the world. 

Na een reboot staat de clock op jiffies zonder het echo commando. In Xen luistert de domU zonder ntp naar de clock van de dom0
