(Wow, 1 year to the day from last post. How funny. Been too busy this last year to write up anything!) These tips are only based on issues I’ve run into on my development server. Â Currently we have a MySQL 5.5.x Ubuntu standard package running in production on Ubuntu 12.04. […]
Recently I ran into a problem booting my root ZFS mirror. Couldn’t get it to load, and only saw blinking cursor or blank screens. Grub could see the FS though! Â I suspect I had a corrupted or out-of-sync zpool.cache file. Don’t ask me how that can happen, because the whole […]
Just ran into this quick blurb… zfs set com.sun:auto-snapshot=false butank/DATA/backups So I have backups running to a secondary storage ZFS pool in my server and today I realized my disk space was consumed by ZFS snapshots. Â I thought, there’s no way even my backups are using that much data, even […]
Recently I upgrade to Ubuntu 12.04. We had UnixODBC running fine in 10.04, but something changed because the odbc drivers couldn’t be found. Â I got an error while running isql: isql -v gregtest [01000][unixODBC][Driver Manager]Can’t open lib ‘/usr/lib/odbc/libmyodbc.so’ : file not found We also couldn’t run our Acucobol apps anymore […]
Well… not much of a guide really. Â Just a very quick how-to on what I did to get Time Machine on my Macbook Pro with OSX Lion 10.7 to save the backup data to my Linux server network share using AFP, rather than SMB (Windows Share), a Time Capsule, or […]
Below is a very quick example of what I did to configure a system DSN connection to a Mysql and PostgreSQL database using UnixODBC drivers on Ubuntu Lucid server from command line only. # Do the obvious, install mysql an postgresql first. :) # install unixodbc apt-get install unixodbc […]
I was asked about the resources used on the Dell Inspiron Mini 1012 using either Windows 7, Ubuntu 10.04 Lucid, or JoliCloud operating systems. Â So… here’s what I found… I didn’t do anything fancy, just boot each up and look at their system/task managers. Â The Linux systems have Chromium/Google Chrome […]
If you are like me, you don’t have time to run nmap scans and do other network maintenance. Running nmap is one of those really fun and useful tools that are easy to use, but since I rarely use it, I never remember the options. Â Today was one of those […]
broadcom STA wireless driver “systemerror: installarchives() failed” on Ubuntu Maverick Dell Mini While attempting to Activate the proprietary Broadcom STA Wireless driver in Ubuntu 10.10 Maverick, I waited and then recieved the error, “systemerror: installarchives() failed”. I am using a Dell Inspiron Mini 1012. I am also booted into the Live […]
I thought I’d be smart and enable data=journal on my root file system. I know its slower, but I prefer data integrity over speed on this system. Even if its not my main data volume, I like the idea of the whole OS running with the best integrity. So, here’s […]
