Commercial SSL certificates with SolusVM

When you install SolusVM it generates a self signed SSL certificate for use with the end user control panel and admin interface, however it would be wise to purchase a certificate from a commercial certificate authority to prevent man in the middle attacks (and get rid of annoying browser warning messages). There are two different methods of installing SSL certificates...

Disabling highlighting of objects in Zimbra web UI

Zimbra has a couple of Zimlets (plugins) that highlight parts of messages when viewed in the Zimbra Web Console such as dates, phone numbers and e-mails and turn them into special contextual links. Whilst this functionality is often quite useful, sometimes you just need to see the raw, unadulterated e-mail without your client interfering with the content – particularly if...

Convert SolusVM from Lighttpd to Nginx

Historically the brilliant SolusVM VPS control panel have used the Lighttpd web server on their master and slave nodes, however it is now possible to use the popular Nginx as an alternative web-server. I’m a big fan of the performance and flexibly of Nginx, not to mention that in my opinion the Nginx configuration files are just much easier to...

Unable to send attachments in Horde

I recently came across a bizzare issue in the version of Horde webmail shipped with Parallels Plesk 9.5.2 where it would allow you to attach files to an e-mail you are composing, but when you send the e-mail the attachment never arrives. Sending the same attachment via the Atmail webmail client or a traditional SMTP client wasn’t a problem and...

Windows Server 2008 with multiple IP addresses on one NIC

If you are running a Windows Server 2008 installation with multiple IP addresses on one interface then you might be surprised to know that the default behaviour when selecting the IP address to use for outbound connections has changed compared to Windows Server 2003. Previously, the “main” IP address on the adapter would have been used for initiating outbound connections...

Zimbra mailbox import/export and migration of e-mail filter rules

Zimbra has a fantastically useful built in system for exporting an entire mailbox, including the contents of the entire e-mail inbox, calendar, address book and briefcase ready to be imported on another Zimbra server either via the web interface or using zmmailbox from the command line. This makes migrating mailboxes between separate Zimbra installations incredibly easy. You can export a...

Parallels Plesk and Atomic Secured Linux

If you are experiencing HTTP 500 Internal Server Error messages from the license management part of the Parallels Plesk control panel when running on Atomic Secured Linux, then you are probably running into some buggy anti-reverse engineering code that Parallels have built into the Plesk software. It seems that Parallels are using ptrace to determine if someone has attached a...

EPEL NSD RPM and the missing PID file directory

NSD is a fantastic authoritative nameserver from NLnet Labs which was developed in conjunction with the RIPE NCC to be a highly scalable, secure authoritative nameserver which has no recursive features by design. In fact, it is such as good nameserver that it is used on three of the root namesevers (k.root-servers.net, h.root-servers.net and l.root-servers.net). Thanks to the EPEL project...

Remove CDP 2.0 cPanel integration

A handy feature of R1Soft CDP Server 2.0 (now known as Enterprise Edition) is that it can integrate with cPanel so that your users can restore their own files from your backups using a self service interface. If you want to remove this integration for any reason, then R1Soft provide a BASH shell script to do this for you: /usr/lib/buagent/control-panels/cpanel/remove-cpanel-integration.sh...

R1Soft CDP 3.0 and commercial SSL certificates

Chances are that you will want to protect the web interface for your R1Soft CDP 3.0 server with a commercial SSL certificate issued by a known, trusted certificate authority. After all, you are sending some pretty sensitive data between your browser the and the R1Soft CDP 3.0 web interface and you want to know not only that it is encrypted...
