Gah so I was futzing with the acl map on our subversion server. Organizing things into groups. I wasn’t thinking and started uppercasing the users ids when moving them into groups (yes i hate uppercase but its easy to highlight paste them). This of course stopped authentication from working for people who have cached auths returning a 403 error. So how to quickly lowercase a huge swath of ids?
I am sure you are aware of my affinity for the Xen hypervisor. In the last year I have switched over to Citrix Xenserver. With other people managing VMs as well having a nice GUI is helpful. One of my complaints is that the GUI (XenCenter) is a windows only app. C’mon, Citrix, please release a cross platform management console. I’ve got to run a windows VM just to use the GUI (granted I don’t have to use the gui, there is a nice API and console utilities). At any rate today I noticed that I could no longer pull up the console for a windows VM nor could I pull up the performance metrics available in XenCenter. A few searches turned up Kenneth Hunts blog and a post that showed me where to fix it. The windows box running XenCenter has a cache folder located in %AppData%\Citrix\XenCenterMain.exe_Url_xxxxxxxxxx. If you remove the cache you should be able to see the console and performance graphs again. If by chance you remove the entire folder you will need to re-add all dom0s back into XenCenter.
From time to time I have not so pleasant support experiences. Today I had another.
This comes up from time to time for me. Either myself or someone else needs to see what address are either in use or not in use (at least as far as ping is concerned). So here are a few oneliners to hopefully make your day brighter.
This is one of my bosses favorite sayings. I must admit its pretty good and for sure its something you need to do. Its especially something you need to do if you when you walk into a new environment and the previous care taker is no longer available. Check your backup policies, make sure that you aren’t backing up 15 rotating daily copies of a version controlled repository to tape every day (all 15).
Ha! I caught you. I bet you think this post is about HA or some way to keep your servers running. Nope, just an observation. 1,2,3) Today is 9/9/9 4) there are 9 letters in September 5) there are 9 letters in Wednesday 6) it is the 252 day of the year, 2+5+2=9, 7) I was born 9/9/81, 8) 9×9=81, 9) 8+1=9. Wow and to think it was such a problematic day at work!
I love how there is all of this squabbling about what the definition of broadband is. “The Commission should continue to look at maximum advertised speed rather than some measure of ‘actual’ speed,” and consumers have “access to broadband capability” whenever they have the opportunity to purchase services and equipment that enable them to access the Internet at any time and use the types of applications that are most commonly used today, such as e-mail and web browsing.
It looks like I will need a windows backup solution for a small project soon. As you probably know I don’t typically do Windows so I am reaching out. I typically use rsync for most of my backup needs. To be more specific I like to use rsnapshot which is a wrapper around rsync. Have you ever wanted rsync on windows? What did you use. I am aware of several options.
It took me a long time to hunt these down and I think default passwords should be freely available. Aspire webpro (default ip is 172.16.0.10): Administrator Username: ASPIRE Administrator Password: 12345678 Extension Username: extension number Extension Password: 1111 UltraMail (default ip is 192.168.1.250): Service Number: 2000 System Password: CTL I also found a manual for UltraMail, and a UserPro manual for programming the handsets with the web interface. Hopefully none of you are stuck with one of these systems.
I’ve been wiping a lot of hard drives recently. I use shred to do the job. shred -n6 -z -v /dev/sdx What do you do to your drives before disposing of them?
