I put the sats I got for this post to good use and started a (mainnet) test node running lnd v0.18.0-beta.rc1. With this node, I'm opening a channel to my main node (c-otto.de), so that I can configure inbound fees for this channel.

Node pubkey: 025cd50e55b969a418e713b70076333ba1e25929e9e6ec5b937c30a8edc85cc82b

Tor address: 025cd50e55b969a418e713b70076333ba1e25929e9e6ec5b937c30a8edc85cc82b@rpzxlbqkb46r2owiutm6rcndrllcgc3zhxgtjjrlc4wnqkbk4ggwg7yd.onion:9735

Channel open transaction (pending): https://mempool.space/tx/4b418cc13349e5ac65dd5b579bc382a1b510dd06cf6dd03af5a89d73c0b826e8

Alias: "lnd v0.18.0-beta.rc1"

If you want to open a channel to this node, please let me know, so that I can connect to your node - or just open a channel yourself after connecting via tor.

Disclaimer: this node will be down most of the time, and I'll close all channels once I'm done testing.
