Hello and welcome to Rockpenguin Technology. A site purely for practice and fun.
- Wireshark for non-root users - Nothing Earth-shattering here, but this one always trips me up and I spend 10-15 minutes trying to remember how to set it up so that I can wireshark as a non-root user. Works like a charm under Ubuntu, Xubuntu, and Debian 6.x. Prolly works under all Deb derivatives, but I won't stake my career on [...]
- Wireless Mesh (almost there…) - Overview I've been testing a wireless mesh system for the past few weeks and thought I'd post my thoughts. The system I've been testing is the Open-Mesh, and more specifically the OM1P which is a pretty slick little device. For those unfamiliar with the Open-Mesh products, it is designed to be a plug-n-play "public" wi-fi [...]
- Most Awesome CMS, ever! - Well, I've been testing CMS systems for quite some time. While most of them are very nice, some powerful, some simple to setup, none are easy to use by an "end user". At least, that's what I thought until I tried gp|Easy. Every single CMS I've put in front of an end-user has been a [...]
- Ubuntu 10.04 + AVCHD + FFmpeg: Converting .MTS files to MP3 - Well, it's been awhile since I posted last. Been a little busy. Where I work, we have to convert a lot of audio/video to another format for transcription purposes. Mplayer and ffmpeg have been lifesavers for me. However, getting setup to convert the newer .MTS (AVCHD) files that the latest videocams use was a little [...]
- The Pesky HP “Only One Copy?” Mystery Solved! - Here is one that took a bit o' detective work to solve. A client of mine was lamenting how they couldn't print multiple copies to their HP4200 printers, unless the document was longer than one page. If the document was one page, you could set the number of copies to one bazillion and it would [...]
- Automount SMB Share on OpenSUSE: How I got SqueezeCenter to read from a SMB share - Here are the steps: - create the folder which you will use to mount the SMB share, e.g.: mkdir /media/share - edit /etc/fstab: //192.168.1.10/smbshare /media/share cifs username=user,pass=sEcrEt 0 0 - in my case, the share wouldn't automount so I had to create a startup script to mount the drive (/etc/init.d/mount.smb): #!/bin/sh # ### BEGIN INIT [...]
- Automagic Bridged Networking Under *Ubuntu (and maybe Debian?) - I use Virtualbox for all of my virtual machining needs. For some of my guest vms I like to use "host" networking, meaning that essentially the vm will share the hosts network adapter using a bridge and a TAP interface on the host computer to perform its virtual networking magic. However, it can be a little [...]
- Ubuntu and mount.cifs - Using SMB/CIFS under Nautilus was too slow. For Windows shares that I use regularly I figured it would be faster and easier to have the share mounted permanently as part of the file system. This also has the benefit of all Linux programs being able to access the files, not just Gnome based apps. Here [...]
- Removing a Virtual Machine from VirtualBox - Below are the steps to remove a virtual machine from the command line: Remove the disk from the VM: VBoxManage modifyvm xfce-test -hda none Unregister the VM: VBoxManage unregistervm xfce-test Unregister the disk (vdi): VBoxManage unregisterimage disk /path/to/vdi
- Adding a VirtualBox Guest via the Command Line - Needs work... Install the bridge utilities: aptitude install bridge-utils Edit /etc/network/interfaces # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet static [...]
