OpenLiteSpeed OCSP stapling with Comodo PositiveSSL

OpenLiteSpeed supports OCSP stapling, which helps web browsers check the revocation status of an SSL certificate without having to connect to the Certificate Authority’s OCSP servers and so can speed up the SSL connection process. In order to enable OCSP stapling, first we need to construct the intermediate certificate chain which OpenLiteSpeed will use to cryptographically verify the response from...

The Zimbra merry-go-round

I’ve been a big fan of the Zimbra email collaboration system for many years, using it since version 4.5 or 5.0 (I can’t remember exactly). However, in recent years the product has been falling further and further behind competitors such as Microsoft Exchange, particularly in the all important area of redundancy and availability. Email and collaboration are critical to modern...

Missing Junk mailbox in Apple Mail

When setting up a new MacBook Pro recently, I was impressed that all of my mail account settings were synced over via iCloud, but somewhat surprised and confused to find that the “Junk” mailbox for all accounts was missing. I couldn’t find the “Junk” mailbox anywhere – it wasn’t in the list of special folders (Drafts, Sent, Trash etc.) with...

Parallels Plesk hanging on login

I recently came across a strange problem when setting up a new Windows Server running Parallels Plesk 12. Everything was working fine to being with, and then suddenly Parallels Plesk started behaving strangely. I would select some items in a list and press remove and they would be greyed out as if the AJAX had fired in the background, but...

Citrix XenServer XS62E015 update failing to apply

If you’re using XenServer 6.2, you may have some problems installing the XS62E015 update from CTX140808. You go through the normal update procedure – download XS62E015.zip from the CTX140808 Citrix knowledge base article, extract it and upload the XS62E015.xsupdate file to the pool, then apply UUID c8b9d332-30e4-4e5e-9a2a-8aaae6dee91a to the pool, which promptly fails with: The uploaded patch file is invalid....

Misleading companies – part 3

The final part of my rant (see part 1 featuring ConnetU and part 2 featuring IX Reach as well as euNetworks) is all about C4L (A.K.A. Connexions4London), a company who are trying to take the take the practice of claiming to have PoPs which don’t really exist to a whole new level! I should start this with a disclaimer. I...

Misleading companies – part 2

In part 1, I wrote about my experiences looking for IP transit services in Telehouse West and an annoying encounter with ConnetU over a phantom PoP. Part 2 of this rant covers a second requirement from the same project – this time for a pair of 1Gbps layer 1 (wavelength) or layer 2 (MPLS pseudo-wire or VPLS) circuits between two...

Misleading companies – part 1

Something that I’ve never understood is why some companies feel the need to lie on their websites. I’m not talking about ambiguous marketing twaddle about being “a leading provider” etc. but flat out deception. This seems to be particularly prevalent in the hosting/network/data centre industry for some reason. This specific rant was triggered by a recent project which required an...

Twitter integration not working in WHMCS

If you’re having problems with WHMCS’s Twitter integration feature on a CentOS/RHEL server, then chances are that you need to install the php-xml RPM. The Twitter integration in WHMCS uses jQuery to make a POST request to announcements.php detailing the number of tweets to retrieve. This then in turn connects to the Twitter API, parses the response and returns it...

eBay and PayPal DNS hijacked by Syrian Electronic Army

Earlier today, the nameservers on the ebay.co.uk and paypal.co.uk domain were changed to ns1.dnforu.com and ns2.dnforu.com in an apparent hijack. It seems that the Syrian Electronic Army are now claiming responsibility for this on Twitter. They have posted screenshots of the eBay/PayPal MarkMonitor account where they were able to manage the domains in question as well as seemingly had access...
