Free packet sniffer software for mac

RumLog 4.2.3 comes to you as a free logging, QSL handling and printing tool, which is especially designed for the short wave DXer, made by a DXer. Basic logging features are included for the higher bands up to 1.2 cm. RUMlog can handle an unlimited numbers of logs and an unlimited numbers of QSOs per log. An user editable, all time country database is used for automatic DXCC recognition.

Major Features:

1. RUMlog includes routines, tables and an interactive gray line map to support the user in gray line dxing.
2. Using RUMlog you can print QSL card labels and manage your incoming paper QSLs. The Logbook of The World (LoTW) and eQSL are fully supported, and you can create files for the Global QSL service very quick. You can get different statistics for paper- or LoTW QSLs. It's just a mouse click to upload or download new QSLs to/from eQSL or LoTW.
3. RUMlog can use the ON6DP QSL manager database to inform you about managers or addresses and it can build and use an own manager and IOTA database, extracting the information from dx-cluster spots. Provisions are made to query the qrz.com online library.
4. RUMlog keeps you up to date about worked, confirmed or missing DXCCs and provides you with country lists and detailed statistics. Quick log searches or more detailed log queries are possible.
5. RUMlog can establish a dx-cluster connection via the internet or via packet radio. A simple terminal is integrated for a Packet Radio connection. RUMlog will separate DX-spots and alert you via e-mail or Growl when there is a ,new one' DXCC or IOTA spotted. Multiple interactive band maps virtualize activities on the air.
6. RUMlog can interface with two transceivers, setting the main parameter on your TRX from the logbook or vice versa. Kenwood, Elecraft, Yaesu and Icom transceivers are supported.
7. RUMlog has import and export functions to allow exchange of log data in different formats to other logging tools.
8. RUMlog can interface with Google Maps (Web-Browser based) and Google Earth. (Must be installed on your computer)
9. Except the DXCC statistics, RUMlog tracks the most interesting areas of the world for the most important awards: IOTA islands, CQ zones, ITU zones, Grid Squares, US States and German DOKs.

- Completely Open Source using the commercially friendly MPL 1.1 license

System requirements:
-
-
- PTlib

Enhancements
- Fixed race condition in silence insertion algorithm where silence buffer is zero length before the first packet is received. Some downstream channels cant handle this. Now initialise silence buffer to be at a minimum 10 milliseconds.
- Fixed compile without video
- Backport of 22121 from trunk Reintroduce implicit check for NULL buffer accidentally removed in revision 22089
- Fixed empty Alert-Info field being sent in SIP INVITE.
- Fixed display name member of OpalConnection containing ONLY the display name for SIP.
- Fixed call routing issue in simpleopal
- IF we use string options to override the username (Calling-Party-Number) then we override it, no ifs buts or maybes!
- Fixed incorrect detection of remote SIP client putting local side on hold, thanks hongxing.
- Fixed incorrect trace log messages.
- Fixed fax NSE tone detect of CNG/CED being passed up to connection and application, for some reason commented out! Fixed OpenPhone detection that fax mode is already in use when get a CNG/CED indication.
- Fixed switching media format for existing channel, e.g. T.38 mode, was broken by someone.
- Slight change to routing algorithm so if the B-Party is explicitly determined, even when there is no matching "source" route in the table.

Kismet is an 802.11 layer2 wireless network detector, sniffer, and intrusion detection system.
Kismet will work with any wireless card which comes with support for the raw monitoring (rfmon) mode, and can sniff 802.11a, 802.11b, and 802.11g traffic.
Kismet identifies networks by passively collecting packets and detecting standard named networks, detecting (and given time, decloaking) hidden networks, and infering the presence of nonbeaconing networks via data traffic.

Main features:
- Ethereal/Tcpdump compatible data logging
- Airsnort compatible weak-iv packet logging
- Network IP range detection
- Built-in channel hopping and multicard split channel hopping
- Hidden network SSID decloaking
- Graphical mapping of networks
- Client/Server architecture allows multiple clients to view a single
- Kismet server simultaneously
- Manufacturer and model identification of access points and clients
- Detection of known default access point configurations
- Runtime decoding of WEP packets for known networks
- Named pipe output for integration with other tools, such as a layer3 IDS like Snort
- Multiplexing of multiple simultaneous capture sources on a single Kismet instance
- Distributed remote drone sniffing
- XML output
- Over 20 supported card types

Enhancements
- This is a complete rewrite of Kismet (referred to as Kismet-Newcore while under development).
- It includes a new user interface, improved tracking, IDS functions, a plugin architecture... for both server and client, and auto-detection of drivers and supported channels on sniffing devices

ICMP Knock Server is a free tool that uses a concept similar to port knocking, which basically involves waiting for a range of packets that match given criteria before executing some action (typically exposing a port, e.g. for SSH connections, that is kept closed or blocked otherwise).
But instead of listening for TCP or UDP packets to arrive on specific ports in a specific order, it accepts ICMP echo requests and checks if their payload lengths and order of arrival match the given pattern.
The advantage is that this approach works with the standard PING tool. Programs with custom code or (although common) networking tools like netcat plus the ability to execute them are not required.

System requirements:
- Python

CloudVPN is a multi-protocol mesh virtual network. Simply - CloudVPN is capable of transporting any reasonable packet protocol, for any application that needs to communicate.
Cloud nodes act as a meshing and transporting layer, and applications connect to them using a gate socket.
Such client applications include:
- Ethernet tunnel, that uses the cloud as one big virtual network, which, given the mesh properties, also proves to be efficient and secure; and gives CloudVPN the "classical VPN function".
- Secure chat client, using the same security adventages.
- Filesharing client (which really proposed itself as a bittorrent alternative)
- Optimized radio-like broadcasting client
- Whatever else you like.

Enhancements
- Full Win32 support was added with the TAP-Win32 package. Massive cleanup was done. The build system was migrated to autotools, which allows easy compiling on many platforms. Some... compilation fixes and one local socket improvement were made

hping2 is an interactive packet costructor and responses analyzer that uses the same CLI of the ping program (but with a lot of extensions).
hping2 can be used to performs a lot of tasks, like testing of firewall rules, (spoofed) port scanning, et cetera.
The interface is inspired to the ping(8) unix command, but hping isnt only able to send ICMP echo requests.
hping2 supports TCP, UDP, ICMP and RAW-IP protocols, has a traceroute mode, the ability to send files between a covered channel, and many other features.
hping2 is multi-platform and works on the following OSs: Mac OS X, Linux, FreeBSD, NetBSD, OpenBSD, Solaris, Windows.

Main features:
- Firewall testing
- Advanced port scanning
- Network testing, using different protocols, TOS, fragmentation
- Manual path MTU discovery
- Advanced traceroute, under all the supported protocols
- Remote OS fingerprinting
- Remote uptime guessing
- TCP/IP stacks auditing
- hping can also be useful to students that are learning TCP/IP.
