Postfix Monitoring With Mailgraph And pflogsumm On Debian Etch

This article describes how you can monitor your Postfix mailserver with the tools Mailgraph and pflogsumm. Mailgraph creates daily, weekly, monthly, and yearly graphs of sent, received, bounced, and rejected emails and also of spam and viruses, if SpamAssassin and ClamAV are integrated into Postfix (e.g. using amavisd-new). These graphs can be accessed with a browser, whereas pflogsumm (Postfix Log Entry Summarizer) can be used to send reports of Postfix activity per email.

Ubuntu for Non-Geeks, 2nd Edition: A Pain-Free, Project-Based, Get-Things-Done Guidebook

Recently I read the book "Ubuntu for Non-Geeks, 2nd Edition: A Pain-Free, Project-Based, Get-Things-Done Guidebook" from Rickford Grant.

Rickford Grant's approach to teaching Linux in this book is user-friendliness. Rest assured, you will have a most understanding, patient, and genial guide as you embark upon this Linux adventure.

Full of tips, tricks, and helpful pointers, the book is a hands-on, project-based, take-it-slow guidebook intended for those interested in - but nervous about - switching to the Linux operating system. Step-by-step projects build upon earlier tutorial concepts, helping you absorb and apply what you've learned.

Ubuntu Linux for Non-Geeks covers all the topics likely to be of interest to an average desktop user. Inside, you'll learn to:
* Download and install free applications, games, and utilities
* Connect to the Internet and wireless networks
* Configure your hardware, including printers, scanners, and removable storage devices
* Watch DVDs, listen to music, and even sync your iPod
* Download photos and videos from your digital camera, then edit and share them
* Tackle more advanced tasks as soon as you're ready

Whether you're new to computers, looking for a painfree way to make the Linux switch, or just want a low-cost alternative to Windows, Ubuntu is for you. The book from Rickford Grant explains tech concepts in an inviting and effective style - less like an instructor and more like an easygoing friend who doesn't mind answering your questions. It is the perfect companion to your Ubuntu Linux adventures. Full recommendation from me.

Virtual Hosting With vsftpd And MySQL On Debian Etch

Vsftpd is one of the most secure and fastest FTP servers for Linux. Usually vsftpd is configured to work with system users. This document describes how to install a vsftpd server that uses virtual users from a MySQL database instead of real system users. This is much more performant and allows to have thousands of ftp users on a single machine. http://www.howtoforge.com/vsftpd_mysql_debian_etch

I want to show you how to install Xoops on Ubuntu. I used the Ubuntu 6.10 Server Edition, but it will probably work on other systems as well. Xoops is a modern Content-Management-System which can be extended with a variety of modules. http://www.howtoforge.com/xoops_ubuntu

Setting Up Postfix As A Backup MX

In this tutorial I will show how you can set up a Postfix mailserver as a backup mail exchanger for a domain so that it accepts mails for this domain in case the primary mail exchanger is down or unreachable, and passes the mails on to the primary MX once that one is up again. http://www.howtoforge.com/postfix_backup_mx

Sound Juicer profiles

Hello, I'm using Ubuntu 7.04 and Sound Juicer has by default several non-proprietary audio profiles. I've created an Mp3 one, because of my Mp3 portable player. I've followed the instructions mentioned in the program's help and I've installed the GStreamer LAME codec. Selecting the "Active" box hasn't produced any results because it doesn't show on the list of available options when choosing the ripping format. I've installed and uninstalled Sound Juicer but the problem persists. Can anyone give me a help solving this problem?Thanks

Freezing on Installation

Tried to install Ubuntu 7.04 on my old 2001 Compaq Presario Desktop (PentiumR 4 CPU 2GHz, 256MB of RAM), but it always froze at the first step (language) no matter how slow I burned the CD or whatever.Next, I tried to install 6.06, and it goes past the first step, but NOW it always freezes on the second step (location). The slot where it should show options for locations (to the left) is always blank, rendering the screen useless, and the installation officially freezes a few minutes later (the system will be completely unresponsive, despite the fact that the CD Drive is still "running"--the clock even stops going), forcing me to hard reset.I've tried running it in safe mode, but it always gives me some "error", and I've tried using some special boot options (F6) but nothing has worked. Unless I'm mistaken, I believe my computer is powerful enough to run 6.06 (and even 7.04, even though I'm having SLIGHTLY more luck with 6.06).Any help would be greatly appreciated. I've been eager to try Linux for the past week and I'm getting really frustrated.

Trouble reading full ipod disk!!!

I've been using Ubuntu for about 8 months now without a problem. I love it!I hadn't done an update for about 5 months until last week, when about 150 software updates went through. Now I'm having a problem.When I plug in my 40 GB ipod, ubuntu is only reading 11.9 GB of it. It's like I lost all the other disk space. The Ipod is fine because when I plug it into a windows machine, it reads the full 40GBs.Another wierd thing that happened is that, when I turn on my external HD, the icon won't show up on my desktop any more and I can't access it.Can anyone help me fix this problem?Thanks.

Setting Up A Subversion Repository Using Apache, With Auto Updatable Working Copy

Subversion is a free/open-source version control system. That is, Subversion manages files and directories over time. A tree of files is placed into a central repository. The repository is much like an ordinary file server, except that it remembers every change ever made to your files and directories. This allows you to recover older versions of your data, or examine the history of how your data changed. In this regard, many people think of a version control system as a sort of time machine. http://www.howtoforge.com/apache_subversion_repository

Create and Extract .gz,.bz2 Files in Debian

bzip2 and bunzip2 are file compression and decompression utilities. The bzip2 and bunzip2 utilities are newer than gzip and gunzip and are not as common yet, but they are rapidly gaining popularity. The bzip2 utility is capable of greater compression ratios than gzip. Therefore, a bzip2 file can be 10-20% smaller than a gzip version of the same file. Usually, files that have been compressed by bzip2 will have a .bz2 extension.

Splitting Apache Logs With vlogger

Vlogger is a little tool with which you can write Apache logs broken down by virtual hosts and days. With vlogger, we need to put just one CustomLog directive into our global Apache configuration, and it will write access logs for each virtual host and day. Therefore, you do not have to split Apache's overall access log into access logs for each virtual host each day, and you do not have to configure Apache to write one access log per virtual host (which could make you run out of file descriptors very fast). http://www.howtoforge.com/apache_log_splitting_vlogger

Retrieving Emails From Remote Servers With getmail (Debian Etch)

Getmail is a program for retrieving emails from remote servers; it is very similar to fetchmail, but more flexible. For example, it can be configured to deliver mails directly to a Maildir or mbox mailbox without the need for an MTA such as Postfix, but of course it can also pipe the mails through an MTA if you want. Getmail can use so called filters such as SpamAssassin and ClamAV to scan the mails, and you can even tell getmail to delete mails on the original server only after a certain number of days.
