Add Linux as a virtual machine to your Windows 7 laptop without VMWare

by Robin Rowe

HOLLYWOOD, CA (LinuxMovies.org) 2013/4/27 – CentOS is a RedHat-workalike that it very similar to RHEL without the logos. CentOS and Debian are the two of the most popular Linux distros around.

VirtualBox is an open source alternative to VMWare. I upgraded VMWare Player, which I’d been using a long time, because it I had problems installing CentOS 6.4 and the Internet recommended installing the latest version. However, with the new VMWare I couldn’t Read more

Give your Linux system more virtual memory

By Robin Rowe

HOLLYWOOD, CA (Hollywood  Today) 2012/2/27 – Sometimes you need a little more memory for programs that use a lot of memory like Firefox. It used to be you had to dedicate a separate swap partition, but now Linux virtual memory can use a file instead of a partition, like Windows. Here’s how to set that up….

# dd if=/dev/zero of=/boot/swapfile bs=1024 count=524288
# mkswap /boot/swapfile
# chown root:root /boot/swapfile
# chmod 0600 /boot/swapfile
# swapon /boot/swapfile

vi /etc/fstab

/boot/swapfile swap swap defaults 0 0

Lightening Ubuntu and Dropping Unity

Make Ubuntu lighter and more fun to use with a couple apt-get commands

By Robin Rowe

HOLLYWOOD, CA (LinuxMovies.org) 2012/12/31 – Ubuntu is a popular Linux distro that many open source enthusiasts like. It’s based on Debian, but without so many rough edges. You could go instead with a Red Hat-based distro such as CentOS, Fedora or SUSE, but if you’re an open source developer being on a Debian-based distro just seems right. Unfortunately, Ubuntu made a desktop UI change that will tend to drive you nuts.

It’s called Unity. Gnome and KDE users hate it, and everyone else just says, what the f**K? If you like the Playskool interface of Windows XP, you’ll find Unity is a step further past that. Unity is so simple, so easy, that it’s unusable. Lot’s of folks have written about Why Unity Sucks, so let’s not repeat that here. The question is, if you’re not ready to throw out Ubuntu with the Unity bath water, what to do?

Open a terminal window by searching for ‘term’ in the confusing Unity interface. Once you get a Read more

Lighten CentOS Server

A few things to remove that are unneeded on your CentOS server

By Robin Rowe

HOLLYWOOD, CA (LinuxMovies) 9/18/2011 – CentOS is a Redhat-based Linux that many use as a server. Here are a few things to jettison that a server doesn’t typically need.

To disable X11 you could change your run level to 3 and edit the initdefault line in your /etc/inittab file. To get rid of X11 entirely, so you’re not updating useless packages with yum update, use this:

yum groupremove “X Window System”

We may want to put ImageMagick back.

yum install ImageMagick

We don’t need SAMBA:

yum remove samba-common

 

Windows 7 Putty SSH Access Denied Solution

Posted on | August 20, 2011 | 1 Comment

Quick fix for Putty ssh client “Access Denied” hiccup on Windows 7

By Robin Rowe

HOLLYWOOD, CA (Linux Movies) 8/20/11 – Windows doesn’t include an ssh client to connect to our Linux servers, so we use the open source Putty software. This software opens a terminal window where you can enter your login name and password. Windows 7 gave us a surprise, though. It was saying “Access Denied” as soon as a user name was entered, before prompting for the password.

The solution is to create a new Putty connection with GSSAPI turned off. Putty was checking for that type of encryption by default. You can’t turn that off in your saved connection. Turn off GSSAPI first in Putty’s authentication settings, that’s under Connection/SS/Auth/GSSAPI. Then create a new connection and save it.

TIP: To see the event log in order to debug a Putty session, CTRL-click on the terminal window.
