Aprx filter not working with other APRS-IS server

[SV6NOB]

Hello, i'm trying to use some filters on my gateway but if change the APRS-IS server some filters not working. In my aprx.conf file i have:

<aprsis>
passcode XXXXX

#server greece.aprs2.net 14578
server    rotate.aprs2.net

filter "m/200"       # My-Range filter: positions within 100 km from my location
filter  -b/CALL*  # Filter out this one callsign

</aprsis>

If i use rotate.aprs2.net as APRS-IS server all filters works perfect, but if i use greece.aprs2.net, the second filter for blocking packets from "CALL" not working. With rotate.aprs2.net i receive packets from "CALL" but not transmitted to the air. With greece.aprs2.net, all packets from "CALL" are transmitted.

Any idea?

Try moving the following line down to the <digipeater> section of your configuration file into the applicable <source> subsection.

Before suggesting any solutions, can you clarify what it is you're trying to do? Just blacklist the one callsign from getting RF-gated?

I want to block all packets from CALL or CALL-1, CALL-2 etc from APRS-IS to RF.

Just curious why you have the range filter m/200 in there. You don't need it if you just want to gate a few stations. If that is what you are trying to do then use the b/call and specify the stations you want and it will not affect messaging. Why flood aprx with a bunch of unwanted packets.

The range of 200km is it ok. I want to block one specific callsign. How can do this? The filter -b/CALL* in <aprsis> section not working.

As I do every time someone posts their config with a m/200 filter in it, I'll remind you that APRS is only using a 1200bps channel and re-gating all the packets from the Internet back to RF from within 200km of you is often considered abuse by other operators.

It is MUCH better to put some thought into what value you're trying to add to the local RF network. If you're really only interested in gating specific stations like the one beaconing your county's repeater objects or a weather station or something, specifically gate those few stations instead of gating everything except one you don't want.

Answering your actual question, a clean way to blacklist a specific station is using the regex-filter option. Try adding this to your source block instead of the -b filter:

regex-filter source CALL.*

I'd be interested to see how that works for you.

With 200km range from my position there are no too many stations. But the blocked callsign is near my location.
regex-filter source CALL.* with dot after CALL?

[Max Harper]

Just type in 'regex-filter source KG4PID'. I don't know if you need to put in the SSID or not so you'll have to try it. I tested it earlier today and it appears to work.
