Hello Everyone, Due to life changes, I no longe have the time to keep up with my cluster installation the way it needs to be cared for. As a result, K4HNT-02 will be going off line January 31st. I would like to thank the people and nodes that I partnered with the past 5 years. Thanks, Terry

making a backup
by Jan 17 Jan '26

17 Jan '26

Hello I run dxspider on a Pi zero W. Every time I grant a user complete access to the cluster or make some changes I have to make a backup from the SD-card by removing it from the Pi and use Win32diskimager to put the image on the PC and during this proces the cluster is down. Now what I would like to do: I would like to save a backup without removing the SD-card from the Pi. I have SSH anabled. What should I do to copy the image file from the SD-card in the Pi to the PC? 73 Jan PA4JJ -- ____________________________________________________ my dxspider clusters running on a raspberry pi: pa4jj-2 77.174.195.163 port 7300 pa4jj-3 77.174.195.163 port 7388

Update to load commands for bad lists (rebuild and apply changes)
by Kin 15 Jan '26

15 Jan '26

Hi, After giving it a bit more thought, and thanks to Andrea’s suggestion, I have updated the *load* commands for the bad lists. The main goal is to keep the active lists properly maintained. From now on, whenever a bad list is updated (whether entries are added or removed), running load/bad* will *rebuild the list from the files* and *apply the changes automatically*. In practice, this means: * New entries are applied as if we had executed *set/bad**. * Removed entries are handled as if the corresponding *unset/bad** had been applied. Whether the lists are downloaded via *crontab* or edited manually, as long as load/bad* is executed (manually or automatically), the list will remain up to date and in service. This is not incompatible with any other download or update methods you may already be using. You can read the full details in the *README*: https://github.com/EA3CV/dxspider_info/tree/main/download And, of course, all of this is possible thanks to Dirk’s excellent work, his code is a real reference and a genuine source of insight for anyone working with and learning from DXSpider. 73 de Kin EA3CV

DX Cluster Alerts Telegram Channel (Automatic Notifications Only)
by Kin 14 Jan '26

14 Jan '26

Hi, In this Telegram channel: https://t.me/dxcluster_alerts <https://t.me/dxcluster_alerts> as I mentioned before, you have the automatic notifications for bad spotters, origin nodes, and IP addresses. It is not a chat; it is only used to receive alerts. 73 de Kin EA3CV PS The commands shown are intended for DXSpider

Bad spot detection with AI help
by Andrea Timpanaro 14 Jan '26

14 Jan '26

Hi all, in the past few weeks I was experimenting and trying to classify the spots comment using AI. The workflow is the following: Spot is received and forwarded to the AI engine The AI engine returns an "offensive" score probability and category. The score is analyzed and an algorithm decides if it is the case to block the source ip of the spotter. The decision is taken considering several factors (scores of the single spot, score of previous spots from the same ip, rate, ect). If the algorithm concludes that the ip is to be blocked it inserts it in a text list. The bad ip is removed from the list after some time. Since not all the spots in the PC61/PC11 packet contain the source ip, when the source ip is not available, the same logic is applied to the source node. In my cluster I did a further step by automatically inserting/removing the AI detected bad ip and bad node into the respective bad list to drop these spots. I did some tests during the last weekend while the bad spots from the usual individual were coming and the model works pretty well. It took less than 5 minutes to block bad ip and bad nodes. The interesting part is that AI is able also to determine the context: even if in the spot there are no bad words, the comment could result offensive, like (real) example below: +-----------------+---------------------+----------------------------------+-------------+----------+---------+-----------+-------------+---------+ | ip | Data | comment | source_node | dx | spotter | frequency | IA_detected | Blocked | +-----------------+---------------------+----------------------------------+-------------+----------+---------+-----------+-------------+---------+ | 188.217.216.80 | 2026-01-13 19:22:27 | real donkey no brain | S50CLX | PG4T | IC8TEM | 21074 | Y | Y | | 85.148.197.200 | 2026-01-13 19:47:31 | look at yourself monkey | WA9PIE-2 | IC8TEM | PG4T | 21074 | Y | Y | Please note that the AI engine is not "in-line" with the cluster. This means that the offending spot is still visible on the cluster, but once detected, subsequent spots from the same ip (or node, but see below, [NOTE_1]) are blocked. The AI is not always exact at 100%. Consider also the meaning of different terms in different languages. I.e. "ARMI" in italian means "weapons" but also "Italian sailors' amateur radio association", so it's not easy to understand the context of a spot like "ARMI district" ;-) For this reason I have foreseen a white-list in the algorithm. I'm publishing the badip.ai and badnode.ai files here: http://badlist_ai.iz2lsc.eu:4000/badlist The files are updated every 2 minutes. If you want to try it I suggest you to insert in dxspider crontab the download of the badip.ai file every 5 minutes and reload the badip list. A sample crontab is ######### download bad ip AI list every 5 min ############################################### 0,5,10,15,20,25,30,35,40,45,50,55 * * * * spawn('cd /spider/local_data; wget -qN http://badlist_ai.iz2lsc.eu:4000/badlist/badip.ai') 1,6,11,16,21,26,31,36,41,45,51,56 * * * * run_cmd('load/badip') ############################################################################################## [NOTE_1]: Unfortunately at the moment DXspider does not support dynamic addition/removal for badnodes in the same way as badip, so I don't know how to automatically apply the badnode file to the dxspider * Maybe Dirk or Kin can help here.* In any case if you also want to download the badnode.ai file, this is the crontab, but then you have to apply it manually with set/badnode or unset/badnode for every node in the list. ######### download bad node AI list every 5 min ############################################### 2,7,12,17,22,27,32,37,42,47,52,57 * * * * spawn('cd /spider/local_data; wget -qN http://badlist_ai.iz2lsc.eu:4000/badlist/badnode.ai') ############################################################################################## Please note that this is still in the *"test phase"* so please report to me any issue or problem. I hope this could help a bit with preventing the shame we observed in the last week on the cluster. 73 Andrea IZ2LSC -->
