A very quick tip. If you are trying to use the Crontab section of a CPanel (reseller account, etc), you may have some issues trying to setup a simple wget when trying to just get a simple webpage. You’ll get some “AJAX ERROR” please refresh. Very annoying with no error message. In anycase, you can […]
We ran into a situation recently, where a wildcard SSL cert was purchased for a customer. When setting up the cert for the entire server, WHM/CPANEL would not tag the default CPANEL account with the new cert. Apache would serve the SSL, but the Apache conf file was not picking up the domain name.

It seems that no two VPS/Cloud servers are configured the same, nor do they have the same user permissions to install/compile modules into PHP/Lamp. This can be a pain if we need to install a third party […]
We recently started research work for a potential grant and some of the project focused on dynamic visualization of data sources.

It has always been easier to deal with and integrate […]
We’ve recently moved a large client from an ill performing “Virtual Private Server” hosting provider to a more robust solution at a different vendor. We came up with a generic questionnaire to help future clients plan for a move/new system. 1.) What are your needs? Is it a new deployment or are you dissatisfied with […]
From Wikipedia , Cloud computing is described as: Cloud computing is Internet-based computing, whereby shared resources, software, and information are provided to computers and other devices on demand, like the electricity grid. When you are purchasing hosting from a hosting company, beware that the term “Cloud” may be mis-used and may not be what you […]
If you run a linux site that is exposed to the internet, check the /var/log/auth.log or /var/log/secure log files. Chances are you’ll see a bunch of ‘ Failed password for user ‘ attacks on your site.
