Free network system administration software for linux

PHP System Administration Toolkit is a toolkit/framework for the rapid development of system administration Web interfaces in PHP. PHP System Administration Toolkit will provide easy access to, for example, LDAP/xSQL servers.

Network Ustadi is a Web interface for managing network services. It provides firewall management, routing table management, NAT configuration, DHCP server configuration, interface configuration, etc.
To ease the task of network administration, decrease the likelihood of erronous command execution and to maintain all network services from a central point, EnderUNIX SDT anounces the availability of its 9th open-source tool, netUstad.
The tool, designed and coded by one of our developers Ozkan KIRIK, has the capability to generate FreeBSD IPFW and Linux Iptables rulesets. It has been written in C language and includes its own HTTP server.
The newly anounced version provides a web interface for system administrators to add/delete/update IPFW and Iptables rulesets, manage routing table and network interfaces. You can manage your firewall via a TCP/IP connected remote PC, easily.
Enhancements:
- Problems that causes the process to terminate, solved.
- Virtual Server configuration problem fixed.
- Some fixes in nat management module.

Non-Networked File System provides a consistent file system over several non networked UNIX computers (or slow networked). For example on your computer at home and at work using only a floppy disk for the synchronisation.
Main features:
- You are sure to work on the latest version of files.
- You dont need to remember which files are modified on an host and must be transfered on others.
- You dont need to made backup, because if a computer crash the file system is still on the other computers working with NNFS.
- The NNFS medium is choosen by a user shell script, it could be: floppy disk, usb key, serial connection, ...
- Minimal NNFS medium bandwidth to make the updates.
- EASY TO USE: Running ``nnfs command before and after your work.
- Numbered backup of files modified/deleted on NNFS.
- If you modify the same file on several hosts NNFS solves the update conflict.
- The program has been hugely tested.
Enhancements:
- This release fixes the case where the user modifies a file mode while NNFS is running and NNFS is configured in order that a file mode change does not imply file synchronization.

Formerly known as the Ximian Setup Tools, GNOME System Tools are a fully integrated set of tools aimed to make easy the job that means the computer administration on an UNIX or Linux system.
Theyre thought to help from the new Linux or UNIX user to the system administrators. The GNOME System Tools are free software, licensed under the terms of the GNU General Public License.
Main features:
Its main advantages are:
- Full integration with the new GNOME Control Center.
- An user-friendly interface to carry out the main administration tasks.
- The use of a common user interface in every system.
- A common structure that makes easy the development of new system tools.
Nowadays there are tools for managing:
- Users and groups
- Date and time
- Network configuration
- Bootloaders
- Runlevels

LMS (LAN Management System) is the integrated system of networks management designed for various size internet providers (ISP).

That software writed in PHP, Perl and C, works with variuos database systems.

KNetworkLED is a KDE system tray app that basically mimics the behaviour of the windows network activity system tray icon.
Main features:
- Docks into KDE system tray.
- Has a configuration dialog from which you can select what network device to monitor (out of the ones you have available)and how often you want to poll that device for activity (100ms to 1000ms).
- Tooltip popup when mouseovering the systemtray icon that displays what device is being monitored and how many TX/RX packets have been transmitted/recieved.
Enhancements:
- Poll Timer was not updating on the fly when user changed it.

Linux Mobile System project (LMS) is a full Linux system whose support is the new USB Flash Memory Drives. The intention is to boot any PC with USB support with our system and therefore we will have every administration and analysis applications that we have selected, so we will not need install it. This way, always we will be able to get our Linux system ready to use in our pocket.
This project arose with the intention to study the Linux system of exhaustive way and simultaneously enjoy with it. The initial idea is to fuse two separated disciplines: the programming and the systems management. So well center our study in the denominated "system programming, as much networking level as at device level (drivers).
Main features:
- To initiate our Linux system from memories flash USB.
- The system will be a selection of common GNU tools in every system: disk diagnosis, memory, hardware, networks monitoring tools, etc.
- LMS Tux
- As far as possible well develop new tools and/or utilities with the objective to study deeply the underlying technology.
- The programming languages used will be C, C++, Python and Perl, without forget the system shell scripts.
- The resources minimization (disk space, memory...) isnt a functional objective of the developments.
LMSs main aim is to achieve a highly specialized distribution of GNU/Linux which can carried through the USB Flash Memory Drives. Once the distribution is ready in the USB device, it can be carried in your own pocket and you can start up any PC x86 with no need to install it directly in the PC.
The LMS system is aimed at the development of specific tasks such as network administration, security analysis of networks, and recovery and repair of host data, as well as all information exchange, which is what makes it different from other portable systems such as "live CDs". The main idea is to carry all the potency of Linux and our tools in our own pockets, ready to be used.
