Noticed Dag Wieers' blog post regarding the CentOS Download Page and thought I'd try help get the wiki download page ranked higher in Google search results for "centos download".

Mozilla Firefox 3 Beta 5 has been released. In addition to its much improved memory usage--it uses less memory than IE, Safari or even Opera--it also has many other performance enhancements including improved connection parallelism.

Get the latest Firefox beta here or take a look at the Beta 5 release notes here

I've been running Firefox 3 on both Linux and Windows since Beta 3 and I've been very impressed with its speed and memory usage (or lack thereof ).

UPDATE: This article explains in detail the changes that were made to improve Firefox 3's memory performance.

So I logged into my work's GoDaddy account yesterday to make some DNS changes and I noticed that in October 2005 GoDaddy appraised our domain name. We're pretty proud of our million dollar domain so I thought, "this will be fun!" According to GoDaddy we could fetch a whopping $48.00 - $134.40 for our domain! Maybe we should sell it after all!

One of the great new features in Fedora 8 is the inclusion of the PulseAudio sound server. PulseAudio allows multiple streams of audio to be played at once, eliminating the worry of having your sound card locked up by another running program. There's also a handy volume control applet that will let you set the volume of each audio stream independently. That's right folks, listen to your MP3s, watch (and listen!) to a YouTube video, and voice chat with your IM buddies, all at the same time and with independent control over each program's volume. Setting up PulseAudio is very easy. Read on for instructions.

The problem with vacation auto responders like 'vacation' for sendmail is that spammers often fake the From: address. Auto responding to these addresses can get your mail server blacklisted. To avoid this you can setup your autoresponder with procmail and, if you are running a spam filter on your machine, you can tell procmail to auto respond only if the X Spam Status header is 'No.' To accomplish this copy the following into ~/.procmailrc in the home directory of the user you want auto responses for. Make sure to make any neccessary changes to MAILDIR, SENDMAIL and the three instances of 'you@yourdomain.com':

There is a bug with numerous NVidia graphics chips that causes the mouse pointer to be invisible in GNOME and GDM (possibly also KDE, I haven't tried it). I discovered this bug on a fresh install of CentOS 5 but its possible that the issue also applies to CentOS 4 as well as Fedora releases. The fix is relatively easy and solved the problem for me on an nForce motherboard with a built-in GeForce 6100 video card. Edit your xorg.conf file and add the line Option "HWCursor" "off" to your videocard device section so that it looks something like this:

The ever-popular, ever-slick Clearlooks GNOME theme is just minutes away for you CentOS users. Its available via the kbs-CentOS-Extras repo. Download this file and pop it into /etc/yum.repos.d/. Then do

yum install gnome-theme-clearlooks gnome-theme-clearlooks-bigpack

If you'd rather not enable the kbs-CentOS-Extras repo system-wide you can download the packages and install them manually. Get them here and here.

You can also install some other GNOME themes with

yum install gnome-themes-extras

or get the package here.

Now you can install other Clearlooks-based themes like Gilouche as well.

The IEs4Linux project makes installing and running Internet Explorer on Linux a cinch. Just follow these simple instructions. Their script will download and install IE6 and, optionally, IE5 and IE5.5 as well. Everything is automated and extremely easy. You can also install Internet Explorer 7 by following these instructions. I was able to get all four versions of IE running on both my CentOS and Fedora machines in no time. There are non distro-specific instructions as well as instructions for the Ubuntu/Xubuntu/Kubuntu, Fedora, Gentoo and Debian distributions. Basically, if you're running Linux with Wine and cabextract installed you're good to go. Many thanks to the IEs4Linux project for making this so easy for us. We should all seriously consider donating to the project.

UPDATED: Mar-21-2007

Due to the popularity of this post I've decided to include instructions for all three of the most popular methods for installing Firefox 2 on Fedora Core 6. Read through the three options to decide which works best for you.

Option 1: Via yum with the 'development' repo

This command will allow you to upgrade to Firefox 2 via the Fedora Development repo. This is the most commonly recommended option.

Instructions (as root):

# yum --enablerepo=development update firefox

Pros: Uses "official" Fedora packages

Cons: Doesn't include the (optional) bonuses of option 2

Option 2: Via yum with the 'remi' repo

Remi Collet, an "official" Fedora developer, has made available a repo of packages that provides Firefox 2. The repo updates Firefox and those packages that depend on it and also contains a few bonuses such as an updated XChat package (version 2..

Instructions (as root):

# rpm -Uvh http://remi.collet.free.fr/rpms/fc6.i386/remi-release-1-2.fc6.remi.noarch.rpm

Now make sure that in your /etc/yum.repos.d/remi.repo file you've got enabled=1 and then:

# yum update

Pros: All required packages as well as some extra goodies; new versions of Firefox are automatically installed with yum update

Cons: Not "official" Fedora packages--bugs should not be submitted to the Fedora project

Option 3: Via firefox-2.*.tar.gz from Mozilla.com

I always recommend using RPM packages on Fedora, if possible. However, if you'd like to install Firefox 2 using firefox-2.*.tar.gz from Mozilla.com use this option. One benefit of this option is that Firefox 1.5 remains on your machine so have a choice as to which version to run.

Instructions (as root):

Download firefox-*.tar.gz from Mozilla.com.

# mv firefox-2.*.tar.gz /usr/local/
# cd /usr/local
# tar xvfz firefox-2.*.tar.gz
# mv /usr/bin/firefox /usr/bin/firefox15
# ln -s /usr/local/firefox/firefox /usr/bin/firefox

Firefox 2 will now be your default browser. To run version 1.5 use the command firefox15. I don't recommend running both versions concurrently because they will be using the same profile which might cause problems.

Pros: Firefox 2 co-exists with version 1.5

Cons: Installation isn't as straightforward; must be repeated for future releases of Firefox 2

I don't find myself interested in Windows very often, or any proprietary operating system for that matter, but I ran into this problem on one of the computers in our office and thought I would share the solution. If you come across the problem of spoolsv.exe using 99% CPU usage, never fear. There is a solution. And its a rather easy one. Click here for the fix. Thanks to Tim for his journal entry pointing this out.

I recently added a hard drive to one of my Linux systems and while searching for the best way to copy my old /home filesystem to the new drive I came upon this command:

/sbin/dump 0f - /home | ( cd /new ; /sbin/restore rf - )

Here my new hard drive is mounted on /new and I'm copying the entire filesystem from /home to /new. On my system (CentOS 4) the dump and restore commands are in /sbin/ but other distros may not be consistent so you'll want to make changes to the command as needed.

UPDATED Dec-19-2006:

NOTE: These instruction are for CentOS 4.

The apt-get method of installing sshfs that I had posted here previously did not work for me. I got this error when trying to mount an ssh drive:

shfsmount: shfs filesystem not supported by the kernel

So, I set out to find a different method of installing sshfs (and fuse, which it requires). One, preferably, that would actually work. Well, I found one. Its not the most elegant solution but its effective.

First, download a copy of the fuse source rpm:

wget http://www.devhen.net/centos/fuse-2.6.0-1.src.rpm

Next, install the source rpm and then build the proper fuse rpm's from the .spec file:

rpm -ivh fuse-2.6.0-1.src.rpm
rpmbuild -bb /usr/src/redhat/SPECS/fuse.spec

Next, install the rpms that you have built:

cd /usr/src/redhat/RPMS/i386 (replace 'i386' with your arch, if necessary)
rpm -Uvh fuse-2.6.0-1.i386.rpm fuse-kernel-2.6.0-1.i386.rpm fuse-libs-2.6.0-1.i386.rpm fuse-devel-2.6.0-1.i386.rpm

Now you can install the sshfs-fuse rpm:

wget http://www.devhen.net/centos/sshfs-fuse-1.6-2.i386.rpm
rpm -ivh sshfs-fuse-1.6-2.i386.rpm

** You can try building the sshfs-fuse rpm from its source package if your not on i386**

Now comes the ugly part... For some reason the system can't find the fuse module after installing these packages. So, head over to the fuse project homepage and download fuse-2.6.0.tar.gz. Unpack it and then

./configure
make
make install

and you should be in business. As I said, this is not an elegant solution because you are installing fuse from the tar.gz file on top of the fuse rpms. However, it works for me and that's all that matters right now because I really needed to mount some ssh drives on my workstation.

Mount an ssh drive like so:

sshfs user@remotesystem:/path/you/want/to/mount/ /mnt/mount-point/ -o allow_other

Don't forget the trailing /'s on both the source folder and the mount point. -o allow_other will give all users access to the mounted drive. Type sshfs -h for a list of all of sshfs' options.

The latest stable release of Ubuntu Linux comes with Firefox version 1.0.8 installed. Unfortunately this version is slower than 1.5+ and some of the extensions I use only support 1.5+ so, naturally, I needed to upgrade. I found a page on the Ubuntu Wiki called FirefoxNewVersion that shows you how to install a second copy of Firefox, downloaded from the Mozilla web site, alongside Ubuntu's default Firefox package. Instructions are included on how to change the /usr/bin/firefox script to use the newly installed version instead of the default. This looked like more work than I wanted for a Firefox upgrade--I wanted to stick with .deb packages and didn't like the idea of having two versions of Firefox installed. So, I discovered a way upgrade my Firefox package using Debain backports. Read on for more.



(Some text taken from the Debian backports instructions)

Add this line

deb http://www.backports.org/debian/ sarge-backports main

to your


/etc/apt/sources.list

and these lines

Package: 

Pin: release a=sarge-backports

Pin-Priority: 200

to your

/etc/apt/preferences

(You may need to create this file if it doesn't exist)

This will deactivate all packages from backports.org. Now you need to activate the particular packages you want to upgrade from backports.org (e.g. firefox). Upgrading ALL of your packages from backports.org is certain to cause problems. So, we need to add the following text

Package: firefox

Pin: release a=sarge-backports

Pin-Priority: 999

to

/etc/apt/preferences

for each package that we want to allow upgrading via backports.org. We need to do this for firefox and its dependant packages. These include firefox, firefox-gnome-support, language-support-en and mozilla-firefox-locale-en-gb.

Your /etc/apt/preferences file should look something like mine:

Package: 

Pin: release a=sarge-backports

Pin-Priority: 200

Package: firefox

Pin: release a=sarge-backports

Pin-Priority: 999

Package: firefox-gnome-support

Pin: release a=sarge-backports

Pin-Priority: 999

Package: language-support-en

Pin: release a=sarge-backports

Pin-Priority: 999

Package: mozilla-firefox-locale-en-gb

Pin: release a=sarge-backports

Pin-Priority: 999

Now simply run

apt-get update

and

apt-get upgrade firefox

as usual, or launch 'synaptic', click 'refresh' to reload information from your repositories, find your firefox package, mark it to be upgraded and hit apply.

These notes are designed to help a Linux geek setup SMTP auth on a Linux + sendmail server. Without proper SMTP auth settings your server is liable to be used by spammers and spam bots to send out copious amounts of unwanted mail. This can get your server's IP blacklisted and can really eat up your resources. Needless to say, we need to avoid this. Start by editing your sendmail.mc file (found in /etc/mail). I use the following commands, try replacing the corresponding lines in your mc file with these ones: (Note that lines beginning with 'dnl' are essentially considered comments and are ignored)

define(`confAUTH_OPTIONS', `A')
dnl
dnl Accept PLAIN and LOGIN authentications.dnl
TRUST_AUTH_MECH(`LOGIN PLAIN')dnl
define(`confAUTH_MECHANISMS', `LOGIN PLAIN')dnl


Now you need to rebuild your sendmail.cf file from the .mc file you've just edited:

make sendmail.cf -C /etc/mail

Next we need to make sure saslauthd is running and configured correctly. Edit your saslauthd configuration file (/etc/sysconfig/saslauthd) and replace shadow with pam for the MECH variable like so:

# Mechanism to use when checking passwords. Run "saslauthd -v" to get a list
# of which mechanism your installation was compiled to use.
MECH=pam


Restart sendmail and saslauthd

/etc/rc.d/init.d/sendmail restart
/etc/rc.d/init.d/saslauthd restart


and don't forget to configure your email clients to use authentication when sending outgoing mail.

funny story

Check out Deer Park Alpha 2, Mozilla.org's latest test release. Essentially, Deer Park is the pre-release of Firefox 1.5, due out sometime in the next few months. Its running very stable for me on Windows and Linux. The most notable changes from Fx 1.0 are the ability to reorganize browser tabs by dragging and dropping and much speedier back and forward buttons.

ill show you the way
thru the kitchen to the place
where we can stay and say
'i didn't know that'
..all day

just wanted to call to see
if the grass was still growing
on your bed sheets
and say
i dont need you now!
all i needed to see
was the way you so quickly
noticed me and ran away
well god slept me well that day
and my bed it lasted all day
and when i woke up i was still there
in your house
but you're not home
you're away another day
and our brother sang
to remind me
that may-be, just may-be
we can all be together forever

Firefox comes with some settings turned off by default which, when enabled, actually speed Firefox up quite a bit, especially for those on broadband connections. To sum it all up: your browser normally makes one request to a web page at a time. When you enable "pipelining" it will make serveral at once, effectively speeding up page loading.

To enable these tweaks, following these steps:

1. Type "about:config" into the address bar and hit return. Scroll down and look for the following entries:

network.http.pipelining
network.http.proxy.pipelining
network.http.pipelining.maxrequests

2. Alter the entries as follows:

Set "network.http.pipelining" to "true"
Set "network.proxy.http.pipelining" to "true"
Set "network.http.pipelining.maxrequests" to some number like "30". This means it will make 30 requests at once.

3. Lastly, right-click anywhere and select New -> Integer. Name it "nglayout.initialpaint.delay" and set its value to "0". This value is the amount of time the browser waits before it acts on the information it recieves.

And, you're done. You should see faster page loads, particularly on large pages.
