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

Vulnerability in the WordPress King Size theme
This is the vulnerability: http://catchinternet.com/blog/timthumb-vulnerability-wordpress-security-patch/
Below is a discussion that I have been having with the creators of King Size. I personally find their response unacceptable, but I agree that themeforest is also to blame. I also do not understand why they didn't have an "update notifier" until recently. I also contacted themeforest and waiting for a reply.
-----
Hello King Size Theme team,
My server was cracked using a vulnerability found in timthumb.php, which ships with the King Size Theme.
I checked the theme page on themeforest.net and under version 3.1 it says: "Updated Timthumb (timthumb.php) for security concerns"
Did you send out e-mails to all your customers using King Size < 3.1 about this problem? If not, why not?
Thanks,
Ovi

Hello,
I am sorry to hear about your troubles but its not our responsibility to keep you informed of updates. Its yours as a buyers responsibility to occasionally check in and see if updates are available. As of v3.3 we released an "update notifier" which informs buyers when updates are available via their Dashboards.
Kind regards,

Hello again,
I am sorry but it IS definitely your responsibility, especially when it comes to critical security vulnerabilities.
Please do the right thing and inform your customers or I will do it for you.

Hello Ovi,
And how do you propose we do that when we do not have CONTACT to our buyers? Come on now, be sensible. When you buy a template from theme forest it IS YOUR responsibility. If you cannot deal with that I am sorry, its not our fault though. We announced this information within our comments, as well released an update. We do not have access to contact buyers due to Theme Forest controlling those rights.
As I had mentioned, I am sorry to hear about your troubles but if you came by Theme Forest from time to time and checked on the template you would have clearly known about the issues. We did our part by addressing the issue, its not your responsibility to update your template - not ours.
So please, do the right thing and accept your responsibility, because its not ours. If you disagree with this, you're more than welcome to take it up with Theme Forest and suggest to them that sellers need the ability to contact their buyers but its not going to happen. It's something authors have been asking Theme Forest for some time now. I'm sorry, but we're only able to do what we can, the rest is up to you as a buyer.
Kind regards,
Bryce Wisekal
