# pYSFReflector
|
|
This is a YSF Reflector implemented in python3, mainly compatible with g4klx reflector.
|
|
|
|
## Additional Features
|
|
### Enhanced Blocking List
|
|
With the enhanced blocking list you are able to mute calls based on
|
|
|
|
* callsign of sender
|
|
* callsign of gateway used
|
|
* ip-address of gateway
|
|
|
|
### Blocking On Regular Expression Callsign Check
|
|
It is also possible to use (by default enabled in the YSFReflector.ini) a callsign check based on a regular expression to check the callsign plausibility in callsign-format and length.
|
|
|
|
The result of this check can be overdriven by a whitelist-entry in the blocklist (for example: N0CALL is blocked by default by this expression but could be allowed for special bridging situations).
|
|
|
|
### Muting Matrix
|
|
Here you see a matrix documenting the behavior of the blocking-lists and configuration of regular expression (RE)-check:

|
|
|
|
Within this table following descriptions for the cell-values should help understanding the table:
|
|
* X: Any value
|
|
* YES: set and matches with callsign/gateway/ip-address
|
|
* NO: not set
|
|
* 1: check via RE enabled, normal operation
|
|
* 0: check via RE disabled, but passes everything
|
|
* -1: check via RE disabled, but only pass whitelist
|
|
|
|
### Avoiding Parallel Incomming Transmissions
|
|
There is also a functionality implemented that prohibits parallel transmissions that can happen if two senders transmit at the same time. Here the principle 'first-comes-first-serves' is realized, so the second station in time will just be muted to not disturb the audio.

|
## Easy Installation And Upgrade
|
|
Depending on your used operating system and python3-installation you just have to take care that following libraries are installed:
|
|
|
|
* bisect
|
|
* configparser
|
|
* datetime
|
|
* os
|
|
* queue
|
|
* re
|
|
* signal
|
|
* socket
|
|
* struct
|
|
* sys
|
|
* threading
|
|
* time
|
|
|
|
In most installations this packages are already installed, otherwise you easily can install them with your system-package-manager (for example Debian: apt) or you use pip3 install <package>-command.
|
|
|
|
The configuration file (YSFReflector.ini) is based on the origin YSFReflector.ini of G4KLX's YSFReflector but with added new configuration-items. So If you know the old reflector-software - configuring this one would be straight forward.
