Transfer Zimbra account from one server to another / between servers / Individual Zimbra account migration

http://new.spheron1.co.uk/2011/06/27/zimbra-mailbox-importexport-and-migration-of-e-mail-filter-rules/

You can export a chosen mailbox from the source Zimbra server with:

zmmailbox -z -m user@test.com getRestURL “//?fmt=tgz” > /tmp/user_test.com.tar.gz

And then import it into the destination server with:

zmmailbox -z -m user@test.com postRestURL “//?fmt=tgz&resolve=reset” /tmp/user_test.com.tar.gz

Install a Secondary/Failover IP in an Ubuntu Server 12.04 VM hosted in a VMWare ESXi 5.0 Update 1 physical machine on an OVH dedicated server

Assumptions:
- You have a dedicated server from OVH http://www.ovh.ie/ which supports virtualization
- You installed and configured the VMWare ESXi 5.0 Update 1 image from OVH (using their web interface manager and their OS image)
- You installed an Ubuntu Server 12.04 VM in ESXi
- You requested and got (by e-mail) a Failover IP by selecting your server in the OVH manager, going to Services at the bottom, clicking on on IP Failover, then clicking on "Order an IP Fail-Over" and following their wizard.

Steps (after you got the IP):
- In the OVH Manager, select your physical server from the drop down at the top.
- Click on Services at the bottom (on the page that opens about the physical server)
- Click on "Virtual Mac for VPS"
- Click on "Associate a virtual MAC to an IP address"
- Select the Failover IP you want to use, give the VM a name, and select the Virtual Mac Type (I used "OVH", it works fine with ESXi).
- Click Validate
- Copy paste the new MAC in the vSphere Client - stop your VM, right click on the VM name > Edit Settings > Network Adapter > On the right under Mac Address click on "Manual", then paste the new Mac there. Click OK and start the VM.
- Open the Console to the VM.
- Add the following to /etc/network/interfaces (I assume this file is mostly empty):

iface eth0 inet static
address FFF.FFF.FFF.FFF
netmask 255.255.255.255
broadcast FFF.FFF.FFF.255

auto eth0:1
iface eth0:1 inet static
        address FFF.FFF.FFF.FFF
        netmask 255.255.255.255
        post-up route add MMM.MMM.MMM.254 dev eth0
        post-up route add default gw MMM.MMM.MMM.254
        post-down route del MMM.MMM.MMM.254 dev eth0
        post-down route del default gw MMM.MMM.MMM.254
        dns-search YOUR.DOMAIN.NAME.THIS.IS.OPTIONAL
        dns-nameservers DDD.DDD.DDD.DDD DD2.DD2.DD2.DD2

- Here is the explanation of the IP "variables" above:
MMM.MMM.MMM.MMM = Main (physical) server IP
MMM.MMM.MMM.254 = Main (physical) server IP but with the last part set to 254
FFF.FFF.FFF.FFF = Failover IP
FFF.FFF.FFF.254 = Failover IP but with the last part set to 254 instead of the original part
FFF.FFF.FFF.255 = Failover IP but with the last part set to 255 instead of the original part
DDD.DDD.DDD.DDD = First DNS nameserver
DD2.DD2.DD2.DD2 = Second DNS nameserver (optional)
- Run /etc/init.d/networking restart
- Try to ping the VM IP

Good luck!

Read config files and show VirtualHost configuration in Apache2

apache2ctl -t -D DUMP_VHOSTS

Ubuntu Oneiric 11.10: HDMI audio out on XPS M1330 with Intel Integrated Graphics Card

1) Open Sound Settings, click on Hardware Tab, next to Profile select Digital Stereo (HDMI) Output. The Output tab should now show Connector: HDMI.
2) Open terminal, sudo alsamixer. Go to the right with the arrow keys until you find S/PDIF 1 (1, not 0 or anything else). Unmute it by pressing M. Test audio.

Installing asf_tools (Alaska Satellite Facility Map Ready) on Ubuntu 11.10 Oneiric Ocelot

http://www.asf.alaska.edu/downloads/software_tools

I assume the build-essential package and other basic tools are installed.

apt-get install zlib1g-dev flex bison

Edit asf_tools/src/to_sr/Makefile and asf_tools/src/fill_holes/Makefile and changes the line similar to:
$(CC) $(CFLAGS) $(LDFLAGS) -o to_sr $(OBJS) $(LIBS)
with this line
$(CC) $(CFLAGS) $(LDFLAGS) -o to_sr $(OBJS) $(LIBS) -lm
(add -lm at the end)

then do a normal configure / make / make install installation

Mount SSH folder/directory in Ubuntu

sudo apt-get install sshfs
sshfs user@remote-server.example.com:/remote/path /local/path

Test Zabbix UserParameter

On local machine:
su -c "zabbix_agentd -t some_key" zabbix

On zabbix master:
zabbix_get -s slave.hostname.com -k some_key
