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.

Network Simulator (Ns) is a discrete event simulator targeted at networking research. Ns provides substantial support for simulation of TCP, routing, and multicast protocols over wired and wireless (local and satellite) networks.
Ns began as a variant of the REAL network simulator in 1989 and has evolved substantially over the past few years. In 1995 ns development was supported by DARPA through the VINT project at LBL, Xerox PARC, UCB, and USC/ISI.
Currently ns development is support through DARPA with SAMAN and through NSF with CONSER, both in collaboration with other researchers including ACIRI. Ns has always included substantal contributions from other researchers, including wireless code from the UCB Daedelus and CMU Monarch projects and Sun Microsystems.
Enhancements:
- Major updates were made to the PackMime-HTTP HTTP/1.1 and WPAN modules.
- Solaris/Sun C compilation bugs were fixed.

Network Tracker application is a user (MAC) tracker daemon, for big LANs (campus).
The Network Trackerd builds a table which records which user is connected on which port of a switch by scanning the devices with SNMP in your inventory which is in a MySQL database. Trackerd keeps that table up-to-date by scanning the network regularly.
Thus, you will have the opportunity to know exactly where a user (MAC, IP, UID) is connected on your network !
Your devices are also checked with ping and SNMP, and you are informed with e-mail when any of the devices is not alive.
More over, you may produce various reports about your network infrastructure on the web (cgi) or by using other tools.
Network tracker eases especially to find and shutdown the switch port of the users, when their PCs on the network start to spread viruses or warms using lots of bandwith; so you are able to stop that kind harmfull traffic on the network.
Main features:
- Collects all the MAC addresses and port numbers from CAM tables of the switches.
- Finds IP addresses of the MACs from ARP tables of the routers.
- Finds LDAP uid of the user.
- Check devices on the network with both ping and SNMP for better reliability.
- The daemon sends 2 self check e-mail per day.
- Developped with C.
Enhancements:
- trackerd is now multi-threaded and works very quickly because a new thread is created for each network device.
- MAC tracking code has been reimplemented for multi-threaded use.
- Wireless access point support has been added.
- gnuplot graphics are prepared, showing the active number of users like MRTG graphs.
- tracker now accepts MAC addresses in free format.

My Network Catalog is an indexing engine that allows Windows shares (or Samba shares) to be bound together over a local network.

My Network Catalog allows an easy centralized search of all the files available over the network.

Skipole Network Monitor project is a simple network monitor with built in web server.

It allows the user to input host IP addresses, it then pings these hosts every five minutes and displays their status via a built-in web server, on port 8000.

So calling http://your_pc_address:8000 will display pages showing green, yellow or red host or group symbols.

Each host is pinged four times every five minutes, and symbols are displayed as:

green : if three or four pings are successfull
yellow : if only one or two are successfull
red : if all four fail

As well as hosts, group symbols are displayed, and can be opened to show hosts, or sub-groups nested within. The operator can create groups, and sub-groups via the gui.

lisp-network-server is a simple framework for writing Common Lisp network applications.

lisp-network-server framework takes care of listening on the network, accepting the connection and starting a new thread with handler functions of your network aware application.
