Test bandwidth between two servers

http://stackoverflow.com/questions/426272/how-to-test-internet-connection-speed-from-command-line

on machine1 (host, this one will receive)

iperf -s -p 65000

on machine2 (client, this one will upload)

iperf -c [ip of server] -p 65000

Reverse the machines to test the other way (upload->download or vice versa).

Accessing Going IP Security Camera X37L X37L20M X37L20MA

Assuming you have an IP address like 192.168.1.*

Main stream: rtsp://192.168.1.10:554/user=admin&password=&channel=1&stream=0.sdp?real_stream--rtp-caching=100

Secondary (low quality) stream: rtsp://192.168.1.10:554/user=admin&password=&channel=1&stream=1.sdp?real_stream--rtp-caching=100

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!

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
