My personal PC's backup plan

Here is my personal backup plan for my Ubuntu home desktop: I use Dropbox for my small files. I use mondo for bare-metal recovery.  I exclude from mondo backups /home so it doesn't take too much time and hdd space For /home, every user on the computer has backintime configured I put my mondorescue and backintime backups in an external, USB hard drive.  I own two of them, so I always keep one of them at my father's house and I swap them about every two months.  When I do the swap, I use rsync -aHv --delete /media/Backup2/ /media/Backup1/ | tee rsync.log to sync the "old" backup drive with the "new".  The -H is important because backintime uses hard links and if you don't use this option, you'll end up multiple copies of your files, which will take way too much hdd space on the backup drive.  Thanks to Vivek !

Password manager for Windows, Linux and Android

It's been some time that I want to start using a password manager.  Yesterday I looked at the keepass software.  However, I was wondering which versions were compatible with each other, as on linux, keepassx seems to be compatible only with version 1 of keepass for windows.  Finally, I found out the recipe: Android: keepassdroid Windows: keepass (version 2) Ubuntu: keepass2 (apt-get install keepass2) They all seem to be compatible.  In conjonction  with Dropbox to sync the database, it is fairly easy to use and the DB is always available on all my devices, up-to-date.

Cannot directly copy and paste RRD graph from cacti to a Microsoft Office application

I used to be able to right-click on a cacti graph, copy the image, then simply paste into Outlook or Word.  However, I don't know why, but it stopped working. I did some research and found this post: http://forums.cacti.net/viewtopic.php?f=21&t=46420 stating that using Alt+Ctrl+V, then choosing "Device Independent Bitmap", it works.  It works.

Blackberry to Android

We recently moved away from Blackberry mostly for cost savings. We went with Samsung's Galaxy S Infuse 4g (why such a long name???). Here is my analysis after a few months of use: Pros of the Samsung: Nice touchscreen A real screen I'm almost as fast on the touch keyboard than on the BlackBerry's physical one A lot more applications 15$/month less expensive on the data plan compared to the BlackBerry What I dislike about the Samsung Bluetooth voice dialing not working with my car radio anymore Poor battery life Poor antenna Calls that cut on the highway Calls getting very bad voice quality once in a while, for about 20 seconds GPS signal losses are very frequent I just talked with a support rep at my provider and he says that most problems can be solved by shutting down the phone and starting it at least daily. I'll try that. What I miss from the BlackBerry: BlackBerry Traffic More robust Better 4g signal Easier to find holsters The red LED that let us know that th

Recover a deleted Exchange 2007 mailbox when the AD user has been deleted as well

I had a challenge this week.  I never played with Exchange's  Recovery Storage Groups (RSG) and I had to restore an Exchange mailbox that has been deleted.  The user left the organization a while ago and I don't know why, I couldn't find the .pst that we usually create before deleting the user and mailbox. We use EMC Networker for our backups, but it cannot restore a mailbox if the mailbox has been deleted.  The answer from EMC: The user has to restore the information store (IS) to the RSG and from there, contact Microsoft to find how to export the mailbox out of the RSG. Of course, I didn't contact Microsoft, but I found that: http://technet.microsoft.com/en-us/library/bb795895.aspx So here is what I did: Following the EMC Networker module for exchange admin guide Created the RSG in Exchange Management Shell (EMS) Created the Mailbox Database in the RSG (in EMS Restore the Mailbox Database using Networker (which restores it to the RSG) Then, I just us

Pfsense upgraded to 2.0-RELEASE

I finally had time to upgrade my home firewall (running on a WRAP) to 2.0.  The current release is 2.0.1, but I didn't want to run a FreeBDS liveCD to alter the image, so I used the premodified images available at  http://zhaw.ch/~maym .  Up to now, everything is running smoothly.  I just installed 2.0 on another CF card, then booted from it.  I had to configure the interfaces manually (using serial port), then I could log on to the default IP address, then restore my backup config.  Then it rebooted and everything was fine except that the DNS forwarder service didn't start automatically, I had to start it manually.  I'll eventually reboot to see if that was just this time.  Thanks to the pfSense team!

No Support Linux News

Up to now, the No Support Linux hosting seems to be all well.  I just got a newsletter from them, stating some facts: It has been an exciting time for No Support Linux Hosting. We were recently mentioned in Web Host Industry Review Magazine as a company with a Killer Business Model. We linked to the magazine article on our Online Buzz page: http://www.nosupportlinuxhosting.com/OnlineBuzz.html We recently added new blades into our Xen Cloud Platform cloud hosting environment. The new blade servers each have dual Intel Xeon E5645 CPUs and 96GB of RAM.  Storage continues to perform nicely on our ZFS based SAN units. http://www.nosupportlinuxhosting.com/ServerSpecs.html Performance and uptime have been outstanding at No Support Linux Hosting.  The average uptime since we launched No Support Linux Hosting has been 99.99%.  That is not bad at all for a $1/month web hosting service.  We have definitely managed to outperform many of the more expensive web hosting solutions. http://www.

Folder comparison tool

I was looking for a folder comparison tool for Windows this morning and I found FreeFileSync .  Open-source, free, and quite instinctive and easy to use.  You select 2 folders, click "Compare" and it shows the the difference and the suggested action: Add this file on this side to the other side Replace this file on this side, overwriting the other side  By default, it compares by date/time, but it can also compare by file content (hopefully doing a md5 on the file...).  It is a lot slower, but can be useful in some contexts. It quickly gives you a good idea of what has changed on one side or the other.

Outlook 2007 Add-in with OTRS

We are using OTRS as ticketing system for support requests, and since it is an internal system only, we wanted to give the opportunity to our employees (requesters) to state their ticket's priority.  The OTRS client interface allows that, but can't add a CC: address, which is wanted by our users, so we decided to try to develop an Office Add-in that would do the job. I know that we could have used the built-in prorities (Normal, Low, Important) in Outlook, but we wanted 6 levels.  Priorities are important to us because we wanted to have escalation and reports to monitor if the agents are answering and solving tickets in an efficient manner.  So we made 6 SLAs and postmaster filters in OTRS, and the form adds text at the bottom of the message (i.e. SLA=1).  The filter recognizes this text and sets the appropriate header, so the SLA is present in the ticket when it is created.  We also made a GenericAgent job to match the OTRS priority to the SLA of tickets.
