A3Com is a set of Perl modules and utilites which use SNMP to manage 3Com switches, such as SS3900s, SS9300s, and CoreBuilders. Tools included will search/dump/store bridge tables, ARP tables, retrieve system info, save and restore configurations in batch mode, upload new software in batch mode, change passwords, reboot switches, dump VLAN configurations, and more.
adsl.sh is a Bash script to easily manage an ADSL pptp connection (most French "France Telecom" ADSL equipment uses this). It's pre-configured for this kind of connection, but you can easily edit the script to make it suit your needs. It can also update your IP adress on dhs.org and/or dyndns.org, and gracefully restart Apache (if you use VirtualHosts, it's mandatory when IP changes).
Angel is a simple yet useful tool to monitor the services on your network. Technically speaking, it's a Perl program that runs every 'n' minutes (usually fired from your cron) and calls different perl subprograms (referred to as "plugins" from now on) to do the actual testing. It will then generate an HTML table containing the status of your network.
Anteater is a log analyser for MTA logfiles (such as those produced by sendmail and postfix). The tool is written in 100% C++ and is very easy to customize. Input, output, and the analysis are modular class objects with a clear interface. Currently, there are modules for reading the syslog format of sendmail and postfix that do up to eight useful analyses and write the result in plain ASCII or HTML, to stdout or to files.
Apmiser is a daemon that monitors the CPU usage patterns of your laptop and automatically switches between power-saving mode (in which the CPU is underclocked) and normal mode, depending on whether it thinks you will need the extra CPU speed. This lets you leave your laptop in it's power-saving state without having to suffer from poor performance when you need to perform a CPU-intensive task. Apmiser currently only supports IBM Thinkpads via tpctl, but support can be easily added for any laptop that supports switching power-saving modes programmatically.
APSR is a network testing tool designed to send and receive arbitrary network packets. Its main purposes are firewall, security, routing, and a lot of other tests. It can also be used to analyze your network. The project is split into three main programs: apsend to create and send packets, aprecv to dump the network traffic, and the apsrlib which provides the appropriate low-level functions. A very wide range of protocols are supported by the aprecv program. The application layer is implemented through modules using a simple API. Modules can be written in Perl, Ruby, C, or PCL (a special-purpose packet construction language).
This is a Linux driver for the Artec AS6E scanner. It scans on all available hardware resolutions in color, greyscale, and lineart, and functions in EPP, PS/2, and SPP parallel port modes. It can be used as a stand-alone program from the command line, or through the SANE (Scanner Access Now Easy) project's software.
Astaro Security Gateway (formerly Astaro Security Linux) is an all-in-one network security gateway that includes a firewall, intrusion protection, antivirus, spam protection, URL filtering, and a VPN gateway. Features include a modern packet filter, intrusion detection and prevention, portscan detection, application control, content filtering, virus detection for email and Web traffic, profile handling, L2TP, IPSec, SSL, and PPTP VPN tunneling, spam blocking, proxies for HTTPS, HTTP, FTP, POP3, SMTP, DNS, VoIP, SOCKS, and Ident, logging, and reporting. It supports Ethernet, VLAN, PPP, PPPoE, PPPoA, Cable Modem, IPv6, QoS, Link Aggregation, and WAN-Uplink-Load balancing in routing, and bridge mode. The WebAdmin GUI, Install Wizard, Change Tracking, Printable Configuration, and Up2Date service make it easy to install, manage, and maintain.
The Autofs CD Changer patch allows you to automount the different slots of a CD changer. It automatically changes the slots and remounts CDs as needed, giving the impression that they are all simultaneously mounted. It's not much use for multisession stuff, but works fine for mp3 lists that span many CDs.
