Gmail Backup done !

 | Wednesday, 9. March 2011 0:05

After I found out that also Gmail maybe has a need for Backup I found a few Ideas / Software to made a Backup.

First I remember that now Zarafa is in Fedora ! –> Thanks to kanarip http://planet.ergo-project.org/

So that’s easy setup a Fedora 14 on my KVM Hosts and install the Zarafa Community Version of it.

http://fedoraproject.org/wiki/Zarafa
http://www.ghacks.net/2010/06/16/zarafa-fedoras-exchange-killer/

# yum install zarafa zarafa-webaccess mysql-server httpd

# service mysqld start
# service zarafa-server start
# service zarafa-gateway start
# service zarafa-spooler start 

# zarafa-admin -s
# zarafa-admin -c USERNAME -e USERNAME@localhost -f “Zarafa Tester” -p PASSWORD
# service httpd restart

 

Then go to http://Server/webaccess –> done

maybe also make them persistent against reboot with “chkconfig Servicename on” per Service.

Then the Problem pops up how to sync my Gmail account with the Zarafa Server. So Imapsync was the first choice, but it turns out that it could be tricky not not so performant :-(

http://www.zarafa.com/wiki/index.php/Imapsync_migrating_to_a_new_server

http://www.linux-france.org/prj/imapsync_list/msg00017.html

http://www.bouthors.fr/wiki/doku.php?id=en:linux:imapsync

http://blog.otelconsulting.com/2010/01/imapsync-to-gmail-script/

# imapsync –noauthmd5 –allowsizemismatch –syncinternaldates –host1 imap.gmail.com –ssl1 –port1 993 –user1 YYYYYYYYYY@gmail.com –password1 XXXXXXX  -sep2 / –prefix2 “” –host2 192.168.1.245 –user2 YYYYYYY –password2 ZZZZZ –folder “[Gmail]/All Mail” –regextrans2 ‘s/\[Gmail\]/Gmail/’ —useheader ‘Message-Id’ —skipsize –dry

Also the Server need lot of Memory, first I think 512 MB is enough, Wrong I go to 1GB / 2CPU now its better ( see graph, red is swap before go to 1GB). Also the process toke very long and skip lot of mails.

 

so  I search another Methode and found it with OfflineIMAP

“Be aware that this is a Offline Version and will be synced back to Gmail if you delete or change something in the Offline Version next Time you sync !!!!!”

http://www.bramschoenmakers.nl/en/node/713

 

#sudo apt-get install offlineimap

and just add ~/.offlineimaprc to your homedrive

[general]
accounts = GMail
maxsyncaccounts = 3

[Account GMail]
localrepository = Local
remoterepository = Remote

[Repository Local]
type = Maildir
localfolders = /storage/Gmail_Backup

[Repository Remote]
type = IMAP
remotehost = imap.gmail.com
remoteuser = your_username@gmail.com
remotepass = your_password
ssl = yes
maxconnections = 1

#Setting realdelete = yes will Really Delete email from the server.
#Otherwise "deleting" a message will just remove any labels and 
#retain the message in the All Mail folder.
realdelete = no

Cluster with Fedora 13 / RHEL 6

 | Tuesday, 7. September 2010 22:55

After building my new Fileserver I decide to add Clusterservice to it. Because the Fedora 13 Cluster will be very similar to Red Hat Enterprise Linux 6 which I will use at Work.

Because there is no explicit Doc for Fedora 13, I had help from Fabio thanks really for help!

So just install it:

# yum install ricci luci

one package was missing

# yum install pyOpenSSL

also you have to disable or adjust the Firewall rules

# service iptables stop;chkconfig iptables off
# service ip6tables stop;chkconfig ip6tables off

then go to https://yourhost:8084 and configure a cluster
that’s it

Problems:

I was not able to start luci on my Fileserver, I had to install a new Server which is anyway needed if you want build a cluster. Also you need only one luci Server.

- Bug 630755 – Web-based cluster administration luci don’t start

Then I had a Error 500 when i want check a already build services. no Idea why but I had to delete it and rebuild it.

- Bug 631496 – Error 500 from luci when try to edit a Service

Oracle Umgang mit OpenSource

 | Tuesday, 20. April 2010 22:45

Ich persönlich habe so meine Zweifel wenn ich so lese wie Oracle mit Open Source umgeht, das funktoniert eher nur dort wo es gerade nützt.

Dann hört es aber sicher schnell auf. Jetzt soll doch das ODF Plugin für Microsoft Office über 50 € kosten!

Ubuntu Lucid Lynx mit Verbindung zum iphone?

 | Sunday, 11. April 2010 22:36

The Linux Kernel should also be a Hypervisor…

 | Sunday, 7. March 2010 23:57

As a Linux developer, it’s hard for me to be that interested in Xen…
When you think about it, it is really quite silly. We advocate Linux for
everything from embedded systems to systems requiring real-time
performance, to high-end mainframes. I trust Linux to run on my dvd
player, my laptop, and to run on the servers that manage my 401k.
Is virtualization so much harder than every other problem in the
industry that Linux is somehow incompatible of doing it well on its own?
Of course not.

Linux With StandardServer another Reason

 | Tuesday, 22. December 2009 1:06

Now also the Red Hat Support for Itanium with RHEL 6 is dead! That exactly what we feel 3 years ago.

I very happy that we decide to go with Standardsever, on the longterm that was the best Decision

OpenExpo Winterthur 2009

 | Monday, 15. June 2009 21:29

So im September ist wieder OpenExpo in Winterthur, soll ich da auch eine Vortrag halten oder soll ich besser schweigen?

Tja habe ja noch bis 19.Juni Zeit um mir das zu ĂĽberlegen.

Weiss eigentlich gar nicht ob das überhaupt jemanden auf der Alpennordseite intressiert wenn ich da was erzähle.
