- Monitoring Multiple Systems With munin (Debian Etch)
In this article I will describe how you can monitor multiple systems with munin. munin produces nifty little graphics about nearly every aspect of your server (load average, memory usage, CPU usage, MySQL throughput, eth0 traffic, etc.) without much configuration. I will install the munin client on all systems that are to be monitored (including the munin server itself); the munin clients will then report to the munin server.

This guide shows how to install and configure Smokeping on Debian Etch to monitor network latency. From the Smokeping web site: "SmokePing is a deluxe latency measurement tool. It can measure, store and display latency, latency distribution and packet loss. SmokePing uses RRDtool to maintain a longterm data-store and to draw pretty graphs, giving up to the minute information on the state of each network connection."

Bonding is the same as port trunking. In the following I will use the word bonding because practically we will bond interfaces as one. Bonding allows you to aggregate multiple ports into a single group, effectively combining the bandwidth into a single connection. Bonding also allows you to create multi-gigabit pipes to transport traffic through the highest traffic areas of your network. For example, you can aggregate three megabits ports into a three-megabits trunk port. That is equivalent with having one interface with three megabytes speed.

This HowTo describes the implementation of Nginx with php5 support (through FastCGI). The fast-cgi process will be initiated via spawn-fcgi. Nginx is a great replacement of Apache with very low memory footprint and contrary to Lighttpd, does not suffer from memory leak over time. You can then use all the memory left to unleash the power of mysql for instance by increasing the default query cache.

This tutorial describes how you can install and configure the Snort IDS (intrusion detection system) and BASE (Basic Analysis and Security Engine) on an Ubuntu 6.06 (Dapper Drake) system. With the help of Snort and BASE, you can monitor your system - with BASE you can perform analysis of intrusions that Snort has detected on your network. Snort will use a PostgreSQL database to store/log the data it gathers.

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.
in Public bookmarks - Preventing Brute Force Attacks With BlockHosts On Debian Etch
In this article I will show how to install and configure BlockHosts on a Debian Etch system. BlockHosts is a Python tool that observes login attempts to various services, e.g. SSH, FTP, etc., and if it finds failed login attempts again and again from the same IP address or host, it stops further login attempts from that IP address/host. By default, BlockHosts supports services that use TCP_WRAPPERS, such as SSH, i.e. services, that use /etc/hosts.allow or /etc/hosts.deny, but it can also block other services using iproute or iptables.

In this article I will show how to install and configure fail2ban on a Debian Etch system. Fail2ban is a tool that observes login attempts to various services, e.g. SSH, FTP, SMTP, Apache, etc., and if it finds failed login attempts again and again from the same IP address or host, fail2ban stops further login attempts from that IP address/host by blocking it with an iptables firewall rule.

In this article I will show how to install and configure fail2ban on an OpenSUSE 10.3 system. Fail2ban is a tool that observes login attempts to various services, e.g. SSH, FTP, SMTP, Apache, etc., and if it finds failed login attempts again and again from the same IP address or host, fail2ban stops further login attempts from that IP address/host by blocking it with an iptables firewall rule.

The quality of my VoIP phone calls suffered whenever I was downloading or uploading anything. This was irritating, especially for those calling me (I heard them better than they heard me). So I poked at Iproute2 and other howtos, especially with regard to VoIP traffic, but I couldn't find anything that worked well. After some playing around, I've found settings that were right for me: consistant VoIP quality, regardless of any activities on the wire.

This tutorial describes how to rescue data from a single hard disk that was part of a LVM2 RAID1 setup. Why is it so problematic to recover the data? Every single hard disk that formerly was a part of a LVM RAID1 setup contains all data that was stored in the RAID, but the hard disk cannot simply be mounted. First, a RAID setup must be configured for the partition(s) and then LVM must be set up to use this (these) RAID partition(s) before you will be able to mount it. I will use the Knoppix Linux LiveCD to do the data recovery.

Fetchmail is a program for retrieving emails from remote servers. Imagine you have five email accounts on five different servers. Of course, you do not want to connect to each of them to get your emails. This is where fetchmail comes into play. If you have a user account on a Linux server, you can make fetchmail download emails from remote servers and put them into just one mailbox (the one of your Linux user), from where you can retrieve them with your email client (e.g. Thunderbird or Outlook).
in Public bookmarks - 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.

This article shows how you can configure a Debian Etch system that has the webhosting control panel ISPConfig installed so that ISPConfig can be accessed on port 80. By default ISPConfig uses port 81 which is a non-standard port and is blocked by some firewalls and ISPs. By using Apache's mod_proxy module, we can avoid this problem. It lets us create a reverse proxy that can fetch the pages from ISPConfig on port 81.
