SOGo and Cyrus IMAP: 2.4 works well.

Sun, 15 Jan 2012 11:00:26 +0100

The open source group-ware suite SOGo can be married happily together with Cyrus IMAP, using the Version 2.4.x of the powerful IMAP server.

The reason lies in the handling of the very important \Seen-Flag.

In Cyrus 2.3.x, you had to type this in your imapd.conf file:

flushseenstate: 1

login account failure: No account present for user

doukoula console login: pascal
Password:            login account failure: No account present for user
   instance svc:/system/console-login:default exited with status 1

What's the problem?
It is the nscd, the Name Service Cache Daemon.

What did I wrong?

The future of IT: CLOSED.

Fri, 13 Jan 2012 20:27:24 +0100

I just read this (in German):

http://heise.de/-1413109
(in short: For ARM devices, Microsoft insists on having UEFI secure boot for their Windows 8 system, and metro apps will only be available on the Microsoft app store with signed code).

My comment:
The game is already at its end, my opinion.

Everybody wants closed platforms, "ecosystems". Nobody wants an open platform, besides us "freaks".

Developers DO want a closed platform, as a radical DRM/Licensing will generate guaranteed revenue and they can bully the user like they want to motivate them to pay more.

known_hosts in hash format - OpenSSH

Fri, 13 Jan 2012 19:09:03 +0100

When you wonder why your known_hosts file has changed or you don't find your hosts:

|1|AEf8B/QCP+1wRKA761Cq/woad4s=|HVEWXKDdRpZmO3GeQ5T37xCFwgE= ssh-rsa AAAAB3NzaC1

yc2EAAAABIwAAAQEAt20HN/iasjy9KEW/BGjtxlsy8oebyEEnZvKAnjMck0EEVbA5rtE4dzisnbrYwZ4

hhdn4D6pR+6shjPsH4VTyAUGwf7usKUvJZP59Ww==

Then your ssh server software is a new version which hashes the known hosts file entries. To remove entries from there because the host key differs (you installed the host completely from scratch), just type:

ssh-keygen -R hostname

or

ssh-keygen -R ipadress

That's it.

If you have a new ssh package, you may hash yourself your known_hosts file by typing:

ssh-keygen -H

Solaris 10 Minimal, getting started with SSH server

Fri, 13 Jan 2012 16:24:49 +0100

Just because it happens again today:

After doing a very minimal Solaris 10 installation without remote services enabled, it is always the same thing to get the SSH server running (Solaris 10 DVD in drive):

# mount -F hsfs /dev/dsk/c2t0d0s0 /mnt

# cd /mnt/Solaris_10/Product

# pkgadd -d . SUNWsshdr SUNWgssc SUNWgss SUNWsshcu SUNWuiu8 SUNWsshdu SUNWsshr SUNWsshu

# cd /etc/ssh

# ssh-keygen -t rsa -b 2048 -f ssh_host_rsa_key

# ssh-keygen -t dsa -b 2048 -f ssh_host_dsa_key

# svcadm enable ssh

Replace device of the DVD drive with your actual configuration.

OpenSSL 1.0.0: New CApath hashes!

Mon, 09 Jan 2012 13:04:50 +0100

A real case of RTFM of OpenSSL ...

After un upgrade of OpenSSL to Version 1.0.0 (from 0.9.8) the certificate authority chain of my certificate did not show up any more (was not given by the TLS server). A look in the OpenSSL manual could have helped to save 20 minutes of error searching :)

A

for i in *.pem; do ln -s $i `openssl x509 -noout -subject_hash -in $i`.0; done

was enough to restore the hash index links for my CA certs (the files did not have any whitespace or punctuation marks in their filename so $i was enough).

The manual states:

-subject_hash
outputs the ``hash'' of the certificate subject name. This is used in OpenSSL to form an index to allow certificates in a directory to be lookedup by subject name.

-subject_hash_old
outputs the ``hash'' of the certificate subject name using the olde ralgorithm as used by OpenSSL versions before 1.0.0.

Google Earth clone from Nokia using WebGL

Sat, 07 Jan 2012 10:21:07 +0100

Fascinating.

Because it uses only WebGL a decent browser dows not need any plugin to render it.

It is faster than Google Earth on my machine and much faster than Google Maps.

But - it does not add additional layers with information, so speed competition my a little bit unfair.

If you want to try:

Merry Christmas and a happy new year!

Android 2.2: wrong arabic characters

Tue, 13 Sep 2011 16:14:32 +0100

Apparently Android 2.2 is not capable of displaying arabic characters possible.

Has this changed in Android 2.3, 3.0 and 3.1?

Solaris 10 / 11 and Oracle VM Virtualbox

Mon, 08 Aug 2011 20:34:13 +0100

As I want to test an IP multipathed iSCSI storage configuration under Solaris 10 and 11 I wanted to set them up in Oracle VirtualBox. It was more or less easy.

Please do not forget to install the VirtualBox guest tools, otherwise the guest will crash as soon as the host system "steals" CPU cycles.

On text-only installs, mount the CD image like this (Solaris 10, CD is IDE master):

# mount -F hsfs /dev/dsk/c0t0d0p0 /mnt

On Solaris 11, the CD was attached to controller "7" target "1" (SATA, Port 1)

# mount -F hsfs /dev/dsk/c7t1d0p0 /mnt

Then:

# pkgadd -d /mnt/VBoxSolarisAdditions.pkg

Solaris 10: upgrading root zfs pool: rewrite GRUB!

Mon, 08 Aug 2011 13:45:18 +0100

If you accidentally upgraded your root zfs pool (which is not recommended until it is supposed to be done from Oracle) do not forget to update your boot signature, your boot archive and your grub installation -

but do not reboot before having done this, otherwise the system won't boot any more.

Don't upgrade the root pool! You won't be able to repair your system when booting from the actual Solaris 10 boot CD (09/10) as the root pool cannot be mounted then. The following steps are to make sure that your system will at least boot when you did the upgrade accidentally.

Example:

Solaris Kernel 144501-19: zpool version 29, zfs version 5

Sun, 07 Aug 2011 19:11:52 +0100

Since Kernel patch/update 144501-19, Oracle now puts zpool version 29 and zfs version 5 into production.

One visible change is the more detailed status when doing a scrub or a resilver operation:

# zpool status
  pool: rpool
 state: ONLINE
 scan: scrub in progress since Mon Aug  8 16:18:21 2011
    1.98G scanned out of 3.66G at 50.7M/s, 0h0m to go
    1.98G scanned out of 3.66G at 50.7M/s, 0h0m to go
    0 repaired, 54.13% done
config:

        NAME        STATE     READ WRITE CKSUM
        rpool       ONLINE       0     0     0
          c1t0d0s0  ONLINE       0     0     0
