   This update targets the v23 release. Additional reliable CJDNS seeds, and feedback on the I2P seeds, is welcome. To verify src/chainparamsseeds.h locally, run:

   0contrib/seeds/generate-seeds.py contrib/seeds > src/chainparamsseeds.h

   Code review ACK bcc5676f16d86a2d271e0d822d836d9c47ef298b I’ve verified that the new I2P node is connectable, and that the generate-seeds output matches. Also, the new entries for CJDNS have the correct BIP155 network type (6). I did not try to connect to CJDNS nodes.

   tACK bcc5676

   I successfully connected to the I2P address added in nodes_main.txt. I also successfully connected to CJDNS node [fcc7:be49:ccd1:dc91:3125:f0da:457d:8ce]:8333, but not to [fc32:17ea:e415:c3bf:9808:149d:b5a2:c9aa]:8333.

    but not to [fc32:17ea:e415:c3bf:9808:149d:b5a2:c9aa]:8333

    Thank you @lsilva01 – can you please re-try connecting? I think I’ve fixed the issue.

    Sure. I am still getting the error connect() to [fc32:17ea:e415:c3bf:9808:149d:b5a2:c9aa]:8333 failed after wait: Permission denied (13).

    Ok, resolved (thanks @vasild and @lsilva01 for testing), I have inbound CJDNS connections now.
