How To Detect Weak Mail Passwords On Your ISPConfig 3 Server

How To Detect Weak Mail Passwords On Your ISPConfig 3 Server

This is a short tutorial on how to find out weak password for your mail users. This will save you you a huge headache since spammers will find out mail account with weak password and send spam email as that user which will result in your mail server being blacklisted.

Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Fedora 18 x86_64)

Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Fedora 18 x86_64)

This document describes how to install a Postfix mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I'll also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota. Passwords are stored in encrypted form in the database. In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses. I will also show how to install SquirrelMail as a webmail interface so that users can read and send emails and change their passwords.

How To Configure PureFTPd To Accept TLS Sessions On Fedora 18

How To Configure PureFTPd To Accept TLS Sessions On Fedora 18

FTP is a very insecure protocol because all passwords and all data are transferred in clear text. By using TLS, the whole communication can be encrypted, thus making FTP much more secure. This article explains how to configure PureFTPd to accept TLS sessions on a Fedora 18 server.

Distributed Replicated Storage Across Four Storage Nodes With GlusterFS 3.2.x On Ubuntu 12.10

Distributed Replicated Storage Across Four Storage Nodes With GlusterFS 3.2.x On Ubuntu 12.10

This tutorial shows how to combine four single storage servers (running Ubuntu 12.10) to a distributed replicated storage with GlusterFS. Nodes 1 and 2 (replication1) as well as 3 and 4 (replication2) will mirror each other, and replication1 and replication2 will be combined to one larger storage server (distribution). Basically, this is RAID10 over network. If you lose one server from replication1 and one from replication2, the distributed volume continues to work. The client system (Ubuntu 12.10 as well) will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.

Virtual Hosting With PureFTPd And MySQL (Incl. Quota And Bandwidth Management) On Fedora 18

Virtual Hosting With PureFTPd And MySQL (Incl. Quota And Bandwidth Management) On Fedora 18

This document describes how to install a PureFTPd 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. In addition to that I will show the use of quota and upload/download bandwidth limits with this setup. Passwords will be stored encrypted as MD5 strings in the database.

Running Contao 3.x On Nginx (LEMP) On Debian Wheezy/Ubuntu 12.10

Running Contao 3.x On Nginx (LEMP) On Debian Wheezy/Ubuntu 12.10

This tutorial shows how you can install and run a Contao 3.x web site on a Debian Wheezy or Ubuntu 12.10 system that has nginx installed instead of Apache (LEMP = Linux + nginx (pronounced "engine x") + MySQL + PHP). nginx is a HTTP server that uses much less resources than Apache and delivers pages a lot of faster, especially static files.

Encrypt Your Data With EncFS (Fedora 18)

Encrypt Your Data With EncFS (Fedora 18)

EncFS provides an encrypted filesystem in user-space. It runs without any special permissions and uses the FUSE library and Linux kernel module to provide the filesystem interface. It is a pass-through filesystem, not an encrypted block device, which means it is created on top of an existing filesystem. This tutorial shows how you can use EncFS on Fedora 18 to encrypt your data.

Setting Up A Standalone Storage Server With GlusterFS And Samba On Debian Squeeze

Setting Up A Standalone Storage Server With GlusterFS And Samba On Debian Squeeze

This tutorial shows how to set up a standalone storage server on Debian 6.0, using GlusterFS and SAMBA, and custom scripts and settings to make life easier.

Installing Nagios 3.4.4 On CentOS 6.3

Installing Nagios 3.4.4 On CentOS 6.3

Nagios is a monitoring tool under GPL licence. This tool lets you monitor servers, network hardware (switches, routers, ...) and applications. A lot of plugins are available and its big community makes Nagios the biggest open source monitoring tool. This tutorial shows how to install Nagios 3.4.4 on CentOS 6.3.

Using PHP5-FPM With Apache 2.4 (+ mod_proxy_fcgi Module) On Fedora 18

Using PHP5-FPM With Apache 2.4 (+ mod_proxy_fcgi Module) On Fedora 18

This tutorial shows how you can install an Apache 2.4 webserver on a Fedora 18 server with PHP5 (through PHP-FPM) and MySQL support. PHP-FPM (FastCGI Process Manager) is an alternative PHP FastCGI implementation with some additional features useful for sites of any size, especially busier sites. On Apache 2.4, we need Apache's mod_proxy_fcgi module to make it work.
