Free mikrotik routers software for linux

IP accounter application measures and graphs traffic for IPv4 and IPv6 netfilter-based routers. Input data is accounted using several abstraction layers (routers, hosts, flows), and IPv6 traffic accounting may be mixed with IPv4.
Enhancements:
- The WEB frontend is still unavailable. There were some minor dificulties running ipaccounter. Still the main issue is when mysql server crashes. The traffic info is then lost until someone fixes it. Therefore it is advised to use some net watching software like Nagios. For further feature enchancements see the ChangeLog. 2006-09-02 by Ondra Ipaccounter-1.0 was released. Only WEB frontend is unavailable at the moment. The accounter is run on one machine. Namely maximus.spi-net.org. There were no fault ancountered so far, but its running only for one week.

Dropbear is a relatively small SSH 2 server and client. Dropbear SSH runs on a variety of POSIX-based platforms.
Dropbear is open source software, distributed under a MIT-style license. Dropbear is particularly useful for "embedded"-type Linux (or other Unix) systems, such as wireless routers.
Main features:
- A small memory footprint suitable for memory-constrained environments - Dropbear can compile to a 110kB statically linked binary with uClibc on x86 (only minimal options selected)
- Dropbear server implements X11 forwarding, and authentication-agent forwarding for OpenSSH clients
- Can run from inetd or standalone
- Compatible with OpenSSH ~/.ssh/authorized_keys public key authentication
- The daemon, keygen, key converter, and client can be compiled into a single binary (ala busybox)
- Features can easily be disabled when compiling to save space
- TCP forwarding support

ddclient is a client for updating dynamic DNS entries for accounts on a number of dynamic DNS providers, including Dynamic DNS Network Services free DNS service.
Many different routers are supported.
ddclient is a small but full featured client requiring only Perl and no additional modules. ddclient project runs under most UNIX OSes and has been tested under GNU/Linux and FreeBSD.
Main features:
- operating as a daemon
- manual and automatic updates
- static and dynamic updates
- optimized updates for multiple addresses
- MX
- wildcards
- abuse avoidance
- retrying failed updates
- sending update status to syslog and through e-mail.

Rodent is an ident daemon that is capable of routing AUTH requests to other machines on your network.

Rodent is intended for routers or to be run on a machine behind a home router.

Rodent allows others to enjoy full ident without the limitations of port forwarding to a single machine.

PACT or Port Accounting & Collection Tool is an SNMP-Tool to do port-accounting for any device that conforms to SNMP standards and has at least a certain amount of SNMP-querieable data (e.g. octets in/out, etc.). Additional tool will allow it to use Apache logfiles as basis for accounting. As of version 0.9f, it also includes support for Linux ipchains.
The idea is based on an old script I wrote that used snmpwalk together with some shell script magic to do accounting on several routers. Among others, two main drawbacks were included in the original version - if the internal offset of a port changed, the script would start recording the wrong port. Also, the speed factor was a problem (it took between 3 and 7 minutes to go through 15 routers and calculate & store the port counters in the database). With PACT, all drawbacks have been addressed. Now, all ports are addressed with their symbolic name, and also speed issues have greatly improved (down to approximately 1 second per router, switch, hub etc.). Plus a nice UI has been added, allowing anybody to alter or create entries or config options.
PACT consists of several different parts, depending on the kind of work being done, and uses a combination of programs, tools and libraries. The core program, the data collector, is based on an example program from the ucd-snmp-package. Its written entirely in C and utilizes the libsnmp from the ucd-snmp-package. The data is collected using configuration data retrieved from a MySQL database, which is also used to store the collected daa.
All UI-specific work is done using HTML pages, most of which using PHP with its MySQL routines to display and administer dynamic data (like host, customer and port data, etc.). Finally, tools to consolidate the collected data and reduce the amounts by adding up on a day-to-day base were planned in C for performance reasons (our current accounting collects nearly two million of data sets per month, which is compressed to about 200000 sets of data), but was written as PHP/SQL-scripts, as just about all work is done in the core of MySQL, so the frontend-performance doesnt matter too much.
Apart from SNMP-ports, PACT can also be used to do accounting for just about anything that can be counted. To date, an additional program exists (for registered users) converting Apache http-logs into PACT data. This was necessary, as doing an accounting for virtual servers running on a single IP is not possible via SNMP ...
Version restrictions:
- Limited to 3 seperate SNMP hosts, but otherwise functionally unlimited.

libstratanetsh project provides source-code to a library (formerly called libnetshclient) for use in the development of applications which require direct communication (using the netsh protocol) with a Foxmoxie Networks STRATA-family router, or any STRATA protocol-capable implementation.
This library may be used to develop client or server implementations, and has also been used for purposes ranging from file transfer to voice applications.
Enhancements:
- TLS implementation optimized, updated API, server-operation support, bugfixes
