Free ping tunnel software for linux

HTTPTunnel is a simple client/server application for creating an HTTP tunnel between two machines, optionally via a Web proxy.
This is a small application for tunnelling an arbitrary TCP socket connection over HTTP. It can be used, for example, to tunnel traffic out from behind a restrictive firewall that only allows outgoing HTTP web connections.
The basic idea is that you run an instance of the HTTP Tunnel application locally in client mode, that then connects out to another instance that you run at the remote end of the tunnel in server mode.
You then connect to the local client end of the tunnel with the application whose traffic you wish to tunnel, and all communications are then wrapped in HTTP. The tunnel may also go via a HTTP proxy, either explicitly or transparently.
Enhancements:
- This release includes some major bugfixes and improvements in the tunneling error detection and retransmission code.
- It also introduces support for building and running under Cygwin.

PingBlog is a tag generator and ping tool for blog directories such as Blogalaxia, VeneBlogs, Technorati, To2Blogs and others.

Webminstats is a basic system static logging application that graphs the results. Its first use is system analysis.

Currently it uses webmin as a base web server and tools package.

The basic design is for a system that can have modules add and removed as easily as webmin itself, well almost.

The current modules are cpu, custom, disk, filesopen, firewall, generic, internet, irq, lm_sensors, load, mem, mysql, network, ping, process, samba, services, snmp, snort, ups, users.

mrtg-ping-probe project monitors round trip time and packet loss to another host. Still on my TODO list: add own min/max/avg rtt calculation, add perl ping module, add rping and rsh support...
mrtg-ping-probe is a ping probe for MRTG 2.x. It is used to monitor the round trip time and packet loss to networked devices. MRTG uses its output to generate graphs visualizing minimum and maximum round trip times or packet loss.
mrtg-ping-probe depends on the following software being installed on your system: perl (at least version 5.6.1), mrtg (I use version 2.8.8, though any mrtg 2.x version should work), and a ping program that displays a summary of the round trip times upon termination or timeout.
mrtg-ping-probe runs on AIX, BSD/OS 2.1, FreeBSD/2.2.x, IRIX/6.2, Linux, Mac OS X (Darwin 5.4), NetBSD, OpenBSD, OS/2, OSF1 V3.2, Solaris 1.1.2 (SunOS 4.1.4), Solaris 2.5.1 (SunOS 5.5.1), Solaris 7 (SunOS 5.7), Solaris 8 (SunOS 5.8), Solaris 9 (SunOS 5.9), HP-UX 9, Windows 98, and Windows 2000 (english, french, portugesee, and spanish locales).
If you install the Windows ping program that comes with Windows 98, Windows 2000, or WinSock 2.x, mrtg-ping-probe will also run on Windows 95 and Windows 4.0.
Support for additional systems is usually easy to add, as described in the file INSTALL.
Act responsible: do not use mrtg-ping-probe to ping devices without the owners permission. Just imagine 10,000 people would decide to ping your hosts ... mrtg-ping-probe is meant to be used within your network to get round trip time performance figures for your network.
Usage: mrtg-ping-probe [-hsvV] [-d deadtime] [-k count] [-l length] [-o ping_options] [-p [factor*]{min|max|avg|loss|integer}/[factor*]{min|max|avg|loss|integer}] [-r [rsh:][user@]host[:osname]] [-t timeout] host
Enhancements:
- new platforms supported: italian Windows 2000 locale.
- bugfixes: on Windows actually return deadtime when we lost all packets, not 0. the ping child process should actually be killed now on Unix platforms.
- changes: ***** Possible Incompatability ***** raised minimum required perl version to 5.6.1. lots of typos fixed.

Socks via HTTP provides a socks tunnel via HTTP.

Socks via HTTP is a program converting SOCKS requests into HTTP requests and tunnelling them through HTTP proxies if needed.

The SOCKS protocol allows programs to traverse firewalls on any port number and is used by many popular programs, like Napster, MSN Messenger, CRT(telnet client) and many others.

Many companies restrict firewall traversals only to HTTP requests, disabling SOCKS proxy.

Socks via HTTP provides a miniature SOCKS server for the SOCKS client, performing its connection through an HTTP proxy to a remote server, which establishes the real connection.

Socks via HTTP is 100% Java, and can run on any OS. It is entirely written in Java.

The hosts can be configured to run arbitrary services, and their personality can be adapted so that they appear to be running certain operating systems. Honeyd enables a single host to claim multiple addresses - I have tested up to 65536 - on a LAN for network simulation.

Honeyd improves cyber security by providing mechanisms for threat detection and assessment. It also deters adversaries by hiding real systems in the middle of virtual systems.
It is possible to ping the virtual machines, or to traceroute them. Any type of service on the virtual machine can be simulated according to a simple configuration file. Instead of simulating a service, it is also possible to proxy it to another machine.

annotate "AIX 4.0 - 4.2" fragment old
# Example of a simple host template and its binding create template
set template personality "AIX 4.0 - 4.2"
add template tcp port 80 "sh scripts/web.sh"
add template tcp port 22 "sh scripts/test.sh $ipsrc $dport"
add template tcp port 23 proxy 10.23.1.2:23
set template default tcp action reset

bind 10.21.19.102 template

The different TCP personalities are learned from reading a nmap fingerprint file. The configured personality is the operating system that nmap or xprobe will return. Personalities can be annotated to determine if they allow FIN-scans for open ports or to select the preference in which they reassemble fragmented IP packets.

Honeyd can be used to create a virtual honey net or for general network monitoring. It supports the creation of a virtual network topology including dedicated routes and routers. The routes can be attributed with latency and packet loss to make the topology seem more realistic.
Because Honeyd interacts with potentially malicious adversaries, you should sandbox it with Systrace. Systrace prevents an adversary from exploiting bugs in your Honeyd scripts.

Subsystem Virtualization

Honeyd supports service virtualization by executing Unix applications as subsystems running in the virtual IP address space of a configured honeypot. This allows any network application to dynamically bind ports, create TCP and UDP connections using a virtual IP address.
Subsystems are virtualized by intercepting their network requests and redirecting them to Honeyd. Every configuration template may contain subsystems that are started as separated processes when the template is bound to a virtual IP address. An additional benefit of this approach is the ability of honeypots to create sporadic background traffic like requesting web pages and reading email, etc.

Network Simulation/Internet-In-The-Box

Honeyd supports assymetric routes and the integration of physical machines into the virtual network topology. As a result, it is possible to use Honeyd for simple network simulations: Physical hosts can be exposed to high latency or packet loss, arbitrary routing infrastructures, etc.

Using GRE tunneling allows the creation of distributed setups that allow Honeyd to scale to larger networks. It also allows virtual machines to be spread across separate address spaces as GRE tunnel selection can be based on the source addresses.
