CSF bugs and updates

ConfigServer Security and Firewall (CSF) is a great program for managing iptables/netfilter firewall rules on Linux servers and performing automated blocks based on various things such as brute force login attempts (check it out at http://www.configserver.com/cp/csf.html) and I really shouldn’t complain given that it’s free, but sometimes I really do wonder if ConfigServer/Way to the Web actually do any testing...

ValueError in Django migration

I’ve recently started developing in Python+Django again for a personal site that I’m working on and for far too long today I’ve been pulling my hair out when trying to write what should be a fairly simple migration using migrations.RunPython() to generate a default value to assign to a new OneToOneField column. The rather confusing error message that I was...

Cumulus attacks on Juniper (again)

I have a lot of time for Cumulus Networks – I think they’re doing some very cool and unique things with their Cumulus Linux operating system for switches and they genuinely have something different to offer, but when they publish blog posts like their one today (https://cumulusnetworks.com/blog/junipers-second-run-up-the-open-networking-mountain/) I lose a lot of respect for them. This seems to be nothing...

cPanel 54

Yesterday cPanel laid out the upcoming changes in cPanel 11.54, or just cPanel 54 as it’s now known (see http://blog.cpanel.com/whats-next-for-cpanel-whm). Whilst light on any details, there are at least some interesting tidbits. The new versioning system This makes very little real world difference, but I can’t help but feel like they’re following Google Chrome and Mozilla Firefox in a race...

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....
