  • inode problems and full disks

    Today we had a customer who had an interesting problem. They were getting the message ‘disk is full’ despite having plenty of free space. Luckily for him, my first thought was ‘inodes?’ I logged in and checked his inode usage

  • Keeping your SSH session alive

    We’re working on servers all day everyday, mostly by SSH. This can be annoying when you switch tabs and then want to go back to another and its timed you out and dead. A nice quick shortcut to kill that session is to type in ‘~.’ This needs to be on a new line so…

  • Daily PostgreSQL Backups

    We have had a few backup scripts posted, however i noticed today when a customer asked for a postgreSQL one we don’t actually have one handy. This one is for a daily dump of the database, rolling over every 10 days

  • Ubuntu Upgrade to 10.04 on your VPS? Read this first!

    Update: Carl has posted some 10.04 upgrade instructions in our howtos section. As often happens, some things happen when you upgrade, and its not always desirable when its a production server. We try and catch these for you and post something to help fix anything that may go wrong. The problem requires a kernel change…

  • Bandwidth useage and control – mod_deflate

    I’ve seen a few times clients with lots of web traffic struggling, and in some cases they had some advance stuff like load-balancing and memcached, and they didn’t even have compressed html! To me is puzzling that many people don’t have it when it takes a couple lines of code and saves typically a good…

  • Picking Your Distro

    We frequently get questions asking which distribution to choose. The short answer is – pick whatever distribution you’re currently using if it’s one that you like and are comfortable using. :) It’s not going to make a tremendous difference at the end of the day and the differences are mostly in the way you’ll manage…

  • Whats using all my disk space up?

    Often we get asked by customers ‘What is using up all my disk space on my VPS?’. Usually we track it down to log files not being rotated or email etc. Here are a few of the commands we use to do that.

  • Glassfish Installation Script

    We do a lot of Java hosting for our customers. As with any technology, there are a lot of different deployment scenarios to choose from. With Java we tend to see mostly Tomcat hosting because most folks don’t require a full fledged application server (and the associated memory costs that come along with it). JBoss…

  • rdiff-backup script using sshfs for larger backups

    We have had a few customers who have much more data to back up, and taking a copy of that every day uses a LOT of disk space and can be time consuming. The answer is rdiff-backup . It does incremental backups whenever you run it, only backing up the difference from the initial complete…

  • Quick and Easy Automatic Backup Script

    At Rimuhosting we do a weekly snapshot backup of your VPS. This means that if anything goes wrong you can revert to the previous image. However since its weekly, not daily, you may find you have lost the data between those dates. This is a backup script that will backup your database and required files…
