Free packet software for mac

Wireshark is one of the worlds foremost network protocol analyzers, and is the standard in many parts of the industry.
WireShark is a project developed on the base of the one that started in 1998. Hundreds of developers around the world have contributed to it, and it it still under active development.

Main features:
- Standard three-pane packet browser
- Multi-platform: Runs on Windows, Linux, OS X, Solaris, FreeBSD, NetBSD, and many others
- Multi-interface: Along with a standard GUI, Wireshark includes TShark, a text-mode analyzer which is useful for remote capture, analysis, and scripting
- The most powerful display filters in the industry
- VoIP analysis
- Live capture and offline analysis are supported
- Read/write many different capture file formats: tcpdump (libpcap), NAIs Sniffer(compressed and uncompressed), Sniffer Pro, NetXray, Sun snoop and atmsnoop, Shomiti/Finisar Surveyor, AIXs iptrace, Microsofts Network Monitor, Novells LANalyzer, RADCOMs WAN/LAN Analyzer, HP-UX nettl, i4btrace from the ISDN4BSD project, Cisco Secure IDS iplog, the pppd log (pppdump-format), the AG Groups/WildPackets EtherPeek/TokenPeek/AiroPeek, Visual Networks Visual UpTime and many others
- Capture files compressed with gzip can be decompressed on the fly
- Hundreds of protocols are supported, with more being added all the time
- Coloring rules can be applied to the packet list, which eases analysis
- Output can be exported to XML, PostScript, CSV, or plain text

System requirements:
- Apples X11

A CoreAudio component that can decode stereo and 5.1 surround sound from A52 and AC-3 audio. This type of audio is often found in DVD movies.
Installing this component is rather simple. If you wish to to be available to all users on the system, simply copy A52Codec.component to /Library/Audio/Plug-Ins/Components. To install it for a single user, place it within Library/Audio/Plug-Ins/Components inside the users home directory. Quit any open Quicktime applications, (including FrontRow) you wish to use this component and relaunch them.
Enhancements:
- Increased audio buffer size to play files with large packet sizes.

LFT, short for Layer Four Traceroute, is a sort of traceroute that often works much faster (than the commonly-used Van Jacobson method) and goes through many configurations of packet-filter based firewalls.

More importantly, LFT implements numerous other features including AS number lookups, loose source routing, netblock name lookups, et al. Though LFT has been around since 1998, its development effort has just recently resumed.

NoTTL intercepts and prevents an application’s attempt to adjust the packet’s Time To Live or TTL. The TTL of a packet on the internet is how long a packet can live before it must reach it’s destination or simply be discarded.

The default TTL for packets on most operating systems is 60 (I think) and each time a packet passes though a router on the internet the TTL is subtracted by 1. Once a TTL reaches zero the packet is discarded. This is so that the internet doesn’t get filled with lost packets that never get anywhere.

iChatSniff is a cocoa program that opens pcap-formatted packet dumps and reads in the iChat audio sessions, then plays them back.

Note : iChat video has not yet been tested and may have unpredictable results.

MacSniffer is a front end to the built-in tcpdump packet sniffer on Mac OS X. MacSniffer allows you to view all of the traffic on a network connection, such as ethernet.

MacSniffer includes a filter editing interface and a filter library to easily construct and reuse packet filters to view a subset of all the traffic on the connection, such as just that destined for a specific host or port.

You can choose the level of detail you want captured, from just the minimal packet headers (showing source and destination hosts and ports) up to a full hex and ASCII dump of the packet contents.

MacSniffer can be useful for diagnosing many network problems, debugging client/server programs, and scanning for particular network exploits in real time.

modttl is intended for network administrators that are looking to modify
the TTL of packets beings sent from their servers.

This allows you to restrict the TTL of packets that you only want going
a certain number of hops from your server or extend the TTL of packets
that for some reason are set to low.

Works on OS X and FreeBSD.

Battlegram is a client that connects to the public chat interface ("Chat") of Blizzard Entertainments Battle.net Internet gaming service. It enables Mac users of Battle.net to communicate with other Battle.net users without having to use one of Blizzards game clients.
Battlegram only connects to the Chat part of Battle.net and does not even touch the private binary part of Battle.net. It will only connect to a recognized Battle.net realm, of which there are four at the time of this writing (USWest, USEast, Europe, and Asia).
Battlegram is not a Battle.net hacking tool and will not perform anything currently forbidden by Battle.nets Terms of Use.
Main features:
- Connects to the Chat interfaces of the USWest, USEast, Europe, and Asia realms on Battle.net
- Plays a sound effect when a user talks in a group, or whispers you (this can be turned on and off)
- Requests the users attention if the user receives a private message (a "whisper") while Battlegram is in the background (this can be turned on and off)
- Supports logging and printing conversations, as well as the system cut/copy/paste interface
- Text colors can be customized
- Supports speaking text
- Supports spell checking
- Supports mouse wheels
- Detects the presence of authentic Blizzard representatives in chat rooms
- Works correctly with the Battle.net "/beep" command
- Available in English and French.
Enhancements:
- Updated contact information.
- Recompiled with GCC 3.1.
- The preferences file has been changed from "Battlegram.plist" to "com.attbi.home.dreamless.Battlegram.plist".
- Finally fixed the packet fragmentation bug. Previous versions had problems with commands sent out in separate packets.
- Added a shortcut to whisper to someone who is in the same channel.
- Fixed problems with prebinding.
- Minor optimizations here and there...
