Webcluster script running on this server

This is a modified version of DL5DI's webcluster, to use cty.dat prefix data file based on dxcc by DJ1YFK.
Ia also colorizes DX spots based on local/dx and on own continent and gives some info on mouse over, like dx's timezone.
Has updated QRZ search links. Now also searches for special callsigns defined in cty.dat.
Needs a small addon in Dx Spider (/spider/local) so that announcements are logged separately for optimized speed.
Tnx. Tom, SP2L, for the review and corrections.
Download tarball here (version 9-Nov-2018).

dx-broadcast 1.1

Dx-broadcast is a small linux daemon intended for packet gateways. It logs in to a DX-cluster and broadcasts obtained dx spots via UI frames on an ax.25 interface.
Grab the source files here, compile and enjoy.

DxFlexServer 1.0 for Windows and Flexnet

The matching pair of the broadcast daemon. Acts as a monitor client to Flexnet and offers the spot as a telnet server, emulating a telnet session to a cluster (to a very small extent).
Needs PC/Flexnet32 and works on Windows Vista32 (probably on 98, XP and Windows 7 also) and supports multiple connections. You can download the executable file here.
Tested only with N1MM logger on Vista32 (and it works...). Please feel free to test drive and criticize.
If you want, get the source files here.

x-bot 0.3

X-bot is a small robot for the WW converse network. It logs in as a user to a specified channel, sets the channel topic and goes 'away'.
It surveys the channel topic and resets it if changed. Also answers to some basic commands (info, version and request to set topic).
Get the sources here, edit your parameters in the C file, compile and launch.

amprd 3.0.1

An user-space IPIP encapsulation daemon with automatic RIPv2 multicast processing and multiple tunnel support for the ampr network.
All RIPv2 processing, encapsulation, decapsulation and routing happens inside the daemon and it offers one or more virtual TUN interfaces to the system for your 44net traffic.
Configuration is done using a simple configuration file. It does NOT support dynamic IPs (yet).
You need to compile it for your system. Download the latest source code here (tgz file).

Git repository: https://git.ampr.org/yo2loj/amprd

For OpenWRT makefiles, follow this link (Tnx. Bill, M1BKF).

Due to changes in the 4.x kernels, there's a problem with the system replying with "icmp unreachable" to incoming IPIP traffic.
This will possible drop incoming traffic, including the RIP broadcasts (resulting in incomplete route tables).
Please switch to an ampr-ripd setup or filter outgoing icmp messages on your WAN interface, using a rule like the one below:

     iptables -A OUTPUT -o ethX -p icmp --icmp-type destination-unreachable -m state --state RELATED -j DROP

Optional, you can use version 3.0 and up, providing a netfilter kernel module to solve this problem.

     This applies to the current and the previous versions. When the new GW will be broadcast as a GW for 44.0.0.1,
     the new GW will be used automatically, even by older versions.

Mikrotik RIPv2 AMPR Gateway Setup Script 3.2
(The script does not work on ROS 7)

This script, installed on a Mikrotik router, enables a complete AMPR gateway setup using RIPv2 broadcasts from amprgw.
Schedule the script to run after the RIPv2 update (Every 5 minutes, starting at let's say 00:06).
Make sure you receive RIP data BEFORE running the script, or nothing will happen.
Also, don't forget to set up your RIP filters so that the route to 44.0.0.1 will be ignored, otherwise it will not work.
Setup details are in this README file.
For RouterOS 6.41 and newer, use this version (text file - use 'save link to'...).
For older RouterOS (pre-6.41) versions) download version 3.1 here (text file - use 'save link to)...
Import and enjoy!
The script does not work on RouterOS 7 due to changes in the RIP handling.

Change Log:
 Version 1.0 (24.Feb.2016):
     - Initial release
 Version 1.1 (24.Feb.2016):
     - Delete obsolete elements only if RIP data is available
 Version 1.2 (25.Feb.2016):
     - Added time stamp comments for routes and tunnels
     - Refined setup description
 Version 1.3 (26.Feb.2016):
     - Added delays to the loops to ease the processor load
 Version 1.4 (12.Mar.2016):
     - Tuneable step delay, improved comments (Tnx. Marc, LX1DUC)
 Version 1.4-FP (12.Mar.2016):
     - Version with fast path enabled (Tnx. Marc, LX1DUC)
     USE ONLY ON ROS VERSIONS 6.33 AND LATER!
 Version 1.5 (9.Apr.2016):
     - Created parent script to allow error recovery and prevent run overlap
     - No data is processed if there are less than 100 RIP entries
     - Converted to Mikrotik export format:
       Just copy to the router and issue an "import" and load the rsc file
       Or copy/paste the content into the console.
       Edit your configuration in the script and enable the scheduler entry.
 Version 1.6 (12.Apr.2016):
     - Run only from wrapper, checks removed from main script
     - Optimized - reduced run time by some 50%
     - Added global state variable for checking
     - Scheduler set to run every 30 min after minute 00:21
     - Main script available here as text file.
 Version 2.0 (12.Apr.2016):
     - Completely rewritten script
     - reduced run time and processor load:
       Without delays, an update on a RB1100AHx2 takes some 5 seconds to update.
       A full creation of all routes and tunnels less than 1 minute.
       On an MIPSBE single core, an update takes around 10 seconds.
       To reduce the processor load, a delay is used (10ms) which makes the script run
       a little longer (less than 1 minute).
     - Main script available here as text file.
 Version 2.1 (15.Apr.2016):
     - Added configuration script so updates can happen only for the main script
       System consists of 3 scripts: wrapper, config and actual update script
       so further updates can be done for a single script only (Tnx. Marc, LX1DUC).
     - Only static routes will be processed, so dynamic ones can co-exist without issues
       (Tnx. Adrian, YO8RXT).
     - Individual script files available here as zip archive.
 Version 2.2 (26.Apr.2016):
     - Removed an useless loop which could crash the script by removing an obsolete tunnel multiple times
     - Added a local variable in update_amprgw to set maximum script overrun admits (was 3, now defaults to 1)
     - Individual script files available here as zip archive.
     - If you already use v.2.1, only update ampr_gw and update_amprgw from the archive file.
 Version 3.0 (21.Jan.2017):
     - Added support for tunnels with BGP announced 44net endpoints
     - Individual script files available here as zip archive.
     - If you already use v.2.x, only update ampr_gw and from the archive file and add manually the new parameter
       "AmprDefaultGw" to your config file (see the example file in the archive).
       "AmprDefaultGw" can be set to your gateway WAN interface name or to your gateway IP.
 Version 3.1 (15.Apr.2017):
     - Individual script files available here as zip archive.
       You only need to update the 'ampr_gw' script. Startup and config scripts are unchanged.
     - The script maintains an interface list named 'ampr-interfaces' with all ampr tunnel interfaces
       The list is persistent, and will be created on first script run. Afterwards it will be
       maintained by each interface add or remove. Useful for firewall rules.
     - Corrected an error when tunnel endpoint host routes where not deleted
     - Added step by step instructions using winbox GUI
 Version 3.2 (21.Dec.2017):
     - Individual script files available here as zip archive.
     - Updated script to ROS 6.41 scripting changes regarding neighbor discovery
     - DO NOT USE on earlier firmwares than 6.41

The script does not work on RouterOS 7 due to changes in the RIP handling.
