Entering A Safe Mirror When Logging In With Unionfs And Chroot
When reading a 'hint' on the website of LinuxFromScratch I discovered the special capabilities of unionfs, specially in combination with chroot. Later I read a HowTo on a wikiwebsite of Gentoo, about entering a chrooted homedirectory when using a special script as shell. Combining these two brings me to using a chrooted environment, which you enter when logging in as a special user. This environment is a exact copy (mirror) of the system you're working on. Because you're in safe copy of the real system, you can do whatever you like, it will never change the system, everything stays inside the cache (the readwrite branch).
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.
Configuring Samba 3.0 To Use The ADS Security Mode (CentOS)
The intent of this article is to show you how to configure your Linux machine and Samba server to participate in a Windows 2003 Active Directory domain as a Member Server using Kerberos authentication. This involves using the security = ADS security mode in Samba.
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.
Installing And Working With Xoops Under Ubuntu 6.10
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.
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.
The Perfect Server - Fedora 7
This is a detailed description about how to set up a Fedora 7 server that offers all services needed by ISPs and hosters: Apache web server (SSL-capable), Postfix mail server with SMTP-AUTH and TLS, BIND DNS server, Proftpd FTP server, MySQL server, Dovecot POP3/IMAP, Quota, Firewall, etc. This tutorial is written for the 32-bit version of Fedora 7, but should apply to the 64-bit version with very little modifications as well.
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”.
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).
Creating A Local Yum Repository (CentOS)
Sometimes it can be handy to set up your own repository to prevent from downloading the remote repository over and over again. This tutorial shows how to create a CentOS mirror for your local network. If you have to install multiple systems in your local network then all needed packages can be downloaded over the fast LAN connection, thus saving your internet bandwidth.
