I remember struggling to get my head around Apache Webserver file permissions. It's a common issue, and I've seen forum posts this weekend with users struggling to get it right. That s what's prompted this post.
To allow the Apache web server process (httpd) to access and serve files from virtual host directories, httpd requires at least read access. However, with content management systems, httpd might also require write access to virtual host directories.
I am happy to report that I have managed to get the VMware View PCoIP Client to work on openSUSE Linux 12 with the GNOME 3 desktop environment. The first client I tried was the VMware View Open Client, which is an open source project. However the View Open Client does not support PCoIP and only connects to the View desktops using RDP. As I am not a fan of RDP, I was keen on getting PCoIP to work.
Some background as to why I needed the PCoIP View Client to work on Linux:
Generally for remote access to my lab, I use the VMware View PCoIP Client for Windows, Android and iOS (on the iPad). VMware has made the PCoIP client available on all of these platforms, but no Linux PCoIP client has been released. This article should get you up and running, but bear in mind that it is not supported by VMware.
This is more of a note for future reference rather than a blog post.
I recently had to replace a RAID-10 member disk as the original disk had developed bad sectors and was causing mostly read related problems in the array. (That’s a whole other story it it’s won right and I don’t have time to get into that now). However, when I tried adding the replacement disk to the server, I found that the disk had a GPT table and not an msdos partition table, unlike the other 3 members in the RAID array. I was therefore unable to add the disk “as-is” to the RAID array as all disks are required to have the same partition table type. I therefore needed to remove the GUID Partition Table and replace it with an msdos partition table.
As I have now rebuilt my Openfiler 2.3 iSCSI box, I thought that it would be wise to document the procedure as I have installed Openfiler on a USB memory stick. This was something I’ve wanted to do this for a while now. Basically, I’m trying to cut back on the number hard disk drives in my environment. If therefore decided to install Openfiler on a USB memory stick instead of another hard drive. I could then run 4 750GB SATA drives in RAID10 and leave the Openfiler OS to run on the USB stick.
As most servers can boot from USB, I didn’t expect any issues with installing and booting Openfiler from USB. However, Openfiler doesn’t load the USB storage drivers when it boots by default. You’ll have to tweak the initrd image in order to boot from USB.
I recently had to renew my self-signed SSL certificate used to publish my Outlook Web Access with Microsoft ISA Server 2004. As it’s been a while since I’ve done OWA publishing, I found myself scrambling for information on the internet until I eventually managed to compile this document. As I would like to use this again in the future, I though I'd post it here for reference.
I always used to use the Microsoft Windows Certification Authority to sign my own SSL certificates, but as I don’t really like the way the Windows Certification Authority does things, and I do like the way OpenSSL does things, so I opted to use OpenSSL on good old trustworthy openSUSE Linux to:
Create a new Certification Authority that I can use for all my private sites
Create a new x509 SSL Certificate to replace the current soon-to-expire SSL certificate in use by my OWA setup.
