A few adjustments required to enable LND Hybrid Mode on raspiblitz

[TrezorHannes]

Went through the guide to enable Hybrid Mode with my Raspiblitz Node, and encountered a few issues, outlined below:

lnd.conf

Writing to lnd.conf directly to adjust

1. external port (optional)
2. tor.streamisolation=false
3. tor.skip-proxy-for-clearnet-targets=true

requires at least further bash script adjustments to achieve 1 and 2.

1

See issue reported here, the port change script /home/admin/config.scripts/lnd.setport.sh checks whether Tor is running, and if true, aborts. Hybrid mode makes this check-function obsolete, or rather needs more delicate checks FWIW, I had to change the port since my other node already occupies 9735 for Hybrid Clearnet.

2

Hybrid Mode and tor.streamisolation=true causes LND daemon to abort and not complete start-up successfully. This is reported by LND systemctl as streamisolation and tor.skip-proxy-for-clearnet-targets=true being incompatible. However, as suggested here, /etc/systemd/system/lnd.service calling /home/admin/config.scripts/lnd.check.sh with a hard-coded streamisolation=true: line 196 > setting ${lndConfFile} ${insertLine} "tor.streamisolation" "true"

Workaround

I have manually adjusted both and successfully booted LND with Hybrid mode, by

• uncommenting the Tor check in /home/admin/config.scripts/lnd.setport.sh
• set streamisolation=false in /home/admin/config.scripts/lnd.check.sh

Hi, are the steps above working for v1.7.1 with LND 0.13.3-beta (using Wireguard not OpenVPN, but that should not change much)

Yes I would certainly say it's working in your environment, too

@openoms wanna target this for soonish 1.8 or push it to 1.8.1? ... related to #2787?
