Free anonymous remailer software for linux

IP::Anonymous is a Perl port of Crypto-PAn to provide anonymous IP addresses.

SYNOPSIS

use IP::Anonymous;
@key = (0..31);
my $object = new IP::Anonymous(@key);
print $object->anonymize("192.0.2.0")."n";

This is a Perl port of Crypto-PAn. Crypto-PAn is a cryptography-based sanitization tool for network trace or log data. The tool has the following properties:

One-to-one

The mapping from original IP addresses to anonymized IP addresses is one-to-one.

Prefix-preserving

The IP address anonymization is prefix-preserving. That is, if two original IP addresses share a k-bit prefix, their anonymized mappings will also share a k-bit prefix.

Consistent across traces

Multiple traces can be sanitized in a consistent way, over time and across locations, even though the traces might be sanitized separately at different time and/or at different locations.

Cryptography-based

To sanitize traces, trace owners provide a secret key. Anonymization consistency across multiple traces is achieved by the use of the same key. The construction of IP::Anonymous preserves the secrecy of the key and the (pseudo)randomness of the mapping from an original IP address to its anonymized counterpart.

This Perl port of Crypto-PAn uses similar logic to that found in Crypto-PAn 1.0, but most importantly maintains consistency in the process so that regardless of implementation, using the same key in each will give consistent results.

USAGE

$object = new IP::Anonymous(@key)

Initializes the electronic codebook object with a 32 8-bit decimal array. This array, consisting of 32 decimals between 0 and 255 inclusive, is the user defined private key for this anonymization session. This 256 bit key should be kept private. The key can be used across sessions to maintain consistent mappings between the original and the anonymized IP addresses.

$object->anonymize($address)

Called with a dotted quad IP address string (e.g. 192.0.2.0). Returns an anonymized version of that IP address as a dotted quad string.

Ghost In The Mail is an anonymous e-mail client for linux written in C and designed in GTK+ 2. Look at the screenshots below to have a better idea of how does it works.
This piece of software allows to send e-mails to any person over the net with a fake email address, and also a fake name. Obviously you can use your true identity. gitmail can also send attached files. Ghost In The Mail uses MIME and Base64 technologies.
Enhancements:
- Full review of the code in order to improve stability and performances.
- Rewrite of all functions that contained malloc(CONST_VAL).
- Added functions gitm_malloc & gitm_realloc that check pointers after allocating them.
- Added some commentaries to describe functions.
- New sources files: functions are distributed into files in a more logical way.
- Files cbbentries.* removed (functions in cbbentries.* are now in history.*) Better core/gui splitting.
- Created a constant GITM_VERSION to hold the version number.
- MIME boundary is now randomly generated.
- Server errors are fully displayed.

Ixion is a media player that uses wxWidgets and GStreamer. Its is just a simple video player that can play at double or half speed. It can be useful as an example of how to write a simple app based on wxWidgets and/or GStreamer.

Ixion is a media player written in C/C++ using wxWidgets and GStreamer. It is not a bleeding edge, full-featured, eye-candy, all-in-one application; Ixion exists only because I needed a video player that could play at double or half speed. However, it can be useful if you want to see how to write a simple app based in wxWidgets and/or GStreamer. Source code is available for download under the GPL license.

You can download the source code from the downloads section. It will compile on most *nix systems ig there are the required libraries, including GNU/Linux.

Alternatively, you can get the source code using anonymous CVS access:
$ cvs -d:ext:anonymous@cvs.lug.fi.uba.ar:/cvsroot/ixion co ixion

Incognito Live CD/USB CD provides software to use various Internet technologies while keeping the user anonymous. The project is based primarily on Tor while including supporting applications. The target use case is that of using a public computer, such as in a library, securely.

This CD may also be copied to a USB drive to provide persisted user settings. The intended user base are those who would like to perform standard Internet communications such as WWW, mail, IRC, IM, etc, while being confident that their anonymity is not compromised. Power users who want precise control over the application and network configuration may be disappointed.

There are full and tiny versions of the CD. The tiny version is intended to fit on small media and basically provides an anonymous web browser. The full version supports a variety of Internet applications.

The Gentoo Catalyst release build tool is used to build the CD. This tool is designed to make the CD easy to maintain. For an update of only Tor it takes a simple version bump and 30 minutes for the tiny CD, two hours for the full version. Human effort is minimal, Catalyst does most of the work. A full update of all software takes several hours to compile, but this is seldom done or needed and again generally requires little human effort. Adding or removing software to/from the CD is also generally trivial.

The following applications are kept up to date as soon as possible. Others may be updated sooner if a major security problem occurs (Firefox, etc.)

*Tor
*TorK
*Vidalia
*Privoxy
*Mixminion

Remaining applications, including the base system, will be updated on a roughly two month schedule.

SystemSearcher project is yet another Linux security scanner.
SystemSearcher is a Linux security scanner written in Perl. It scans single hosts or subnets for anonymous FTP servers, TFTP servers, SMTP servers which allow relaying, SSH servers, Telnet servers, NFS servers with exported directories, mail servers, Web servers (HTTP/HTTPS), well- known trojan ports, and exploitable CGIs.
You can also scan a list of specific servers and specific ports. It uses non-blocking socket communication with a 3-second socket timeout.
It can also scan for proxy servers which are open to the world (on port 80,8080,1080, or 3128), and SMB servers or Windows boxes sharing directories.
Main features:
- Scan a network segment
- Scan for anonymous ftp
- Scan for TFTP server
- Scan for SMTP server which allows relaying
- Scan for SSH server
- Scan for Telnet server
- Scan for Web server (HTTP and HTTPS)
- Scan for proxy server open to the world (Ports 80.8080.1080,3128)
- Scan for NFS server and exported directories
- Scan for Mailservers belonging to your target
- Scan for SMB server or windoze boxes and shared directories
- Scan for exploitable CGIs using whisker (programmed by Rain Forest Puppy)
- Scan for well known Trojan ports
- Scan for one or more open ports

KSendfile is a native SAFT client. Compared to the Bitnet up to now there was no asynchronous file transfer service defined in the Internet. The existing standard file transfer, the ftp, is a synchronous service: an interactive login on both ends of the file transfer is mandatory for the user to set up a connection between both points.
If a user A wants to send a file to user B they have the following choices:
- ftp to a recipients account B
In this case one has to know the password of the recipients account. If A and B are not the identical person, severe questions of security arise and it is not the method of choice. Even if account A and B belong to the same person, the typed ASCII password characters for ftp access will travel open (readable) as ordinary TCP packets through the network.
- ftp using an anonymous ftp server
The file has to be uploaded by A onto the anonymous ftp server using an ftp session. After that A has to notify B about this using e-mail informing this user about the fact that the file is ready for download now. B can get the file now by doing another ftp transfer. This procedures requires a common reachable ftp server, with an upload (write access) facility. During the time the file resides on the anonymous ftp server it is open to anyone, it may be readable, writeable, changeable or erasable.
- sending a file via e-mail
A is sending a file to B enclosed into an e-mail. According to RFC 822 a mail must contain characters from the NVT-ASCII character set, which is a subset of the 7 bit ASCII character set. The file transfer via e-mail is limited to English text documents or the text to be sent must be encoded properly, of course using the NVT-ASCII character set. Encoding procedures like uuencode or MIME are available. It is not a pleasure to use either of them, they dont support all file ownership attributes and they will enlarge the amount of data to be transferred by encoding. In addition to this most of the existing MTAs are not designed to handle large amount of data transfers.
To avoid all the described disadvantages the SAFT-protocol (Simple Asynchronous File Transfer) has been developed and the sendfile software has been created as a reference implementation for UNIX platforms.
Enhancements:
- Fixed a bug in ksendfilenetclient::sendFile when getting status code 531
- Added Resend Function
- Fixed bug in ksendfilenetclient::sendfile in the date function
- Now sends the file date, not the actual system date.
