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.
I recently was having horrible download rates on some VMWare ubuntu images that are hosted on a beefy Win7 box.
Upgrade time for an older storage server (really a workstation), running Ubuntu 10.04. The old workstation did not have any Sata controllers in it, so I had to install a new MASSCOOL XWT-RC018 run-of-the-mill PCI Sata controller. Popped in two brand new Samsung Spinpoing 1 TB drives (SAMSUNG Spinpoint F3 HD103SJ 1TB 7200 RPM) and […]
A recent upgrade to a new Ubuntu server version, caused my dovecote server to not be happy. Apparently in my haste, I had kept my old configuration files for Dovecot that had several features replaced or depreciated. I tried removing the package using “apt-get remove dovecot*”, but my config files were still left behind.
Recently I worked on a client’s workstation that had a very interesting “infection”. Google internet searches would be redirected to random company websites and the Microsoft Windows Update website refused to load properly. The client was running Avast and SpyBot (with Tea-Timer). I turned up the detection level in Avast to show exactly what was […]
Recently I had a project that needed to create and format a word document, based on data from a MySQL database. While the solution was on an MS platform that had Word available, I could only use PHP for the scripting language as it was a language that was used by the rest of the […]
Four steps to add a new hard-disk to a running Ubuntu virtualized session, using Vmware. Add the new hard-disk to the Ubuntu vmware image using Vsphere or VMWare Server. Ssh into ubuntu session and run “echo “- – -” > /sys/class/scsi_host/NUMBER/scan” NUMBER is the scsi host value. It will not hurt rescanning a running host, so […]
I recently setup a test VMWare server environment on my Windows 7 workstation to run Ubuntu LAMP development environments that mirror my production environments. After I install an Ubuntu (or any Nix) environment, I typically install Samba services so I can easily copy code/images back and forth from my workstation to the development box. I […]
