Paessler PRTG Traffic Grapher
(2 votes, average: 9 out of 10) Loading ...Traffic Grapher monitors network traffic and classifies it by IP address, protocol and other parameters. It acquires traffic information through SNMP, LAN and WLAN packet sniffing and Cisco’s NetFlow. It can also monitor latency by measuring PING times. Graphs show live data (for the past five minutes to an hour), averages for up to 48 hours, hourly averages for up to 60, daily average for up to a year, and more. An internal database can export results as CSV files and zip and purge old data. Reports are available in HTML, PDF, Excel and other formats. An internal Web server offers public or authenticated access to the monitoring results.
There’s a freeware version for up to 10 sensors, a 30-day trial of the commercial version, and the full commercial version, all available here.

NetBrute Scanner Suite (Raw Logic Software)
(No Ratings Yet) Loading ...How can you resist a suite with “Brute” in the name? Raw Logic’s NetBrute is a suite of three tools to pound away at your network and reveal the gaps in your security defences.
NetBrute scans a range of IP addresses for resources shared through Microsoft file and printer sharing, as well as any server message block (SMB/CIFS) compatible shared resources (e.g. Samba servers) and determine whether they’re password-protected. (Future versions of NetBrute may incorporate a dictionary attack password tester to ensure the strength of passwords, according to Raw Logic. In the meantime, the company offers a link to a brute force NetBIOS password tester on the same page as the suite download.) It also displays hidden resources using the older Microsoft NetShareEnum API call, and displays the IP address of every machine with sharing enabled, whether it’s sharing resources or not.
PortScan, as the name suggests, scans for listening ports to detect open service ports (for FTP, Web servers, Telnet servers, etc.) and ensure they’re password-protected. You can import your own port list, and Raw Logic helpfully provides a list of TCP ports associated with common Trojan Horses here.
WebBrute attempts a brute force user ID and password attack on Web sites running basic authentication. Users provide a list of user names and dictionary file; WebBrute displays the user name and password of any combination it successfully cracks.
NetBrute runs on Windows 9x, NT, 2000, ME and XP. Note that Windows Vista uses a different version of SMB; it’s probably not compatible. Just another reason to save XP.

Advanced Net Tools (Dreamsys Software)
(1 votes, average: 9 out of 10) Loading ...Advanced Net Tools (or ANT, as it is affectionately known) is a free utility with a ton of useful network management functionality. The network port scanner can scan a range of IP addresses and ports. Share scanner scans for a list of servers and their shared drives. Trace route counts the number of hops between PC and destination, and identifies the slowest links. ARP, route and adapter configuration tools can be viewed in a Windows GUI. There are ping, DNS and statistical utilities, and lots more.
ANT runs on Windows 98/ME, NT 4 (service pack 4 or later), 2000 or XP. And it’s absolutely free from Dreamsys.

Net/FSE (Packet Analytics)
(No Ratings Yet) Loading ...The FSE in Net/FSE stands for “Forensic Search Engine.” This browser-based tool is aimed at network security analysts to allow them to sort through network data in the event of a security alert from intrusion prevention and detection systems, firewalls, etc. Packet Analytics says this helps analysts determine what hosts are associated with the alert, when the activity started and whether it’s ongoing, where the activity started from and how many hosts are involved.
Net/FSE does this by acting as a NetFlow collector and syslog server, so if you’re primarily a Cisco shop, you’re good. According to the company, custom agents can be designed if Netflow’s no use to you. Two presumptions here, since the company hasn’t returned calls asking the questions: We’re presuming the custom agents aren’t free, and that agents for Juniper’s jFlow and Huawei’s NetStream would likely be in stock. Hopefully, CEO Andy Alsop will have set us straight before we have to publish this. (Or, if not, I’m sure he will shortly after.)
Net/FSE was built in Mac OS X and runs on OS X and most distributions of Linux. Check for compatibility here.
And Net/FSE is free … sort of. The free licence captures up to one million events per day and offers free e-mail support. Beyond that, annual licences and support range from $1,495 plus $299 (up to three million events per day) to $18,950 plus $3,790 for up to 50 million events per day.
Remember to rate this if you use it, and use the e-mail link to suggest other handy downloads.
UPDATE: Andy Alsop of Packet Analytics has this to say about agents for Net/FSE:
Net/FSE does not natively handle jFlow or Netstream but custom handlers can be developed. We are working with customers to develop the library of log handlers and the types of log handlers in Net/FSE is all based on the customers needs and infrastructure. In your post about Net/FSE, yes the custom handlers aren’t free but if they have broad market applicability we will most likely do the work at no charge as it enhances our library of handlers.

Network Notepad
(No Ratings Yet) Loading ...J. A. Green’s Network Notepad allows users to create an interactive network design map by dragging, dropping and connecting icons for routers, switches, PCs, servers, hubs, etc. Name the devices, assign them IP addresses and define other properties, then click on the map icons to telnet into or browse the devices on the network.
Network Notepad is generally well-reviewed by download sites and certified clean (no adware or spyware) by Softpedia. The newest version (4.6.3) also adds a Cisco Discovery Protocol (CDP) tool for those running Cisco or CDP-supporting products to auto-discover connected devices. And it’s absolutely free. Green, though, is looking for network icons and sample network diagrams.
Network Notepad runs on Windows 9x and later versions.
