Firewall / Spamassassin: Automatic list update

[imc67]

Every time you execute the script the existing list is replaced by the newly generated version. There might be duplicates at generating the list because IP’s from the first two URL’s can exist in the later ones but that’s not a problem for me.

Thanks again!
I just tried this - it generated merged_list_20240110_091244.txt and formatted_merged_list_20240110_091244.txt but somehow, the temp_data.txt is not generated, and therefore the upload is not successful?

BTW, here's your script with english comments and filenames:

#!/bin/bash

# Current date and time
current_datetime=$(date +"%Y%m%d_%H%M%S")

# Array containing the URLs of the IP lists and their descriptions
declare -a urls=(

Sorry for the Dutch language in the script, ChatGPT is wonderfully writing Dutch without asking haha.

Strange it doesn't seem to work, I extended the script later to upload it in one run to 3 different Cloudrons and that also works perfect. The part of creating the temp_data.txt is exactly the same.

• Do you see the prompt "# Upload to Cloudron Blocklist API with wget..."?
• What happens after that prompt is showed?
• It takes with these lists about 1,5 minute (on a AMD EPYC 7702P 64-Core Processor with 32GB memory) to process it via API so you have to have some patience (This is however exactly the same time like when you use the copy/paste in the GUI).
• After the script is finished the temp_data.txt is deleted, did the script ever finished?
• I execute the script in a LAMP app (on one of the Cloudrons) with only 256MB memory
• last maybe a stupid question but you've set the API token to "read/write"?

I just executed the script (my 3 Cloudrons version) en after about 5 minutes all 3 Cloudrons had the new lists with 60562 IPs (ranges) blocked.

I executed the script with sh script.sh instead of bash script.sh - after doing the latter it worked!
Thanks again.

BTW the output.txt only contains {}...?

@necrevistonnezr said in Firewall / Spamassassin: Automatic list update:

after doing the latter it worked

aha ok, I always use ./script.sh

indeed output.txt also with me contains no data, as I read the script the right way it should contain errors during wget

[necrevistonnezr]

Super!
I have used this script now via cron and everything seems to work fine, including a significant reduction of "denied" mail attempts in the mail log.

I've added the following lines to keep the last 20 url lists, compressed with 7z (which I prefer for compression), for analysis (if needed):

7z a -mx9 "${current_datetime}.7z" "formatted_$output_file"
rm "formatted_$output_file"
rm "$output_file"
ls -td *.7z | grep -v '/$' | tail -n +20 | while IFS= read -r f; do rm -f "$f"; do>

Also: If you use the script, don't just blindly add url-lists. I already managed to lock myself out once by adding the "standard" Firehol list (https://iplists.firehol.org/files/firehol_level1.netset)

With @imc67 permission, I created a community guide from this thread...

[necrevistonnezr]

... thought I got a "Failed pipeline for master | 3dbdac62" notification...

@necrevistonnezr link to the guide, pretty please!

@necrevistonnezr I was looking in the forum Thank you!
