- **Q:** The clightning service is running but when I try to use it (f.e. by running
|
|
|
|
|
`lightning-cli getinfo` as user operator) all I get is `lightning-cli: Connecting
|
|
|
|
|
to 'lightning-rpc': Connection refused`.\
|
|
|
|
|
**A:** Check your clightning logs with `journalctl -eu clightning`. Do you see
|
|
|
|
|
something like `bitcoin-cli getblock ... false` failed? Are you using pruned mode?
|
|
|
|
|
That means that clightning hasn't seen all the blocks it needs to and it can't get
|
|
|
|
|
that block because your node is pruned. \
|
|
|
|
|
If you're just setting up a new node you can `systemctl stop clightning` and wipe
|
|
|
|
|
your `/var/lib/clightning` directory. Otherwise you need to reindex the Bitcoin
|
|
|
|
|
node.

|
- **Q:** My disk space is getting low due to nix.\
|
|
|
|
|
**A:** run `nix-collect-garbage -d`
|
|
|
|
|
|
|
|
|
|
- **Q:** Where is `sudo`?\
|
|
|
|
|
**A:** After [CVE-2021-3156](https://www.openwall.com/lists/oss-security/2021/01/26/3),
|
|
|
|
|
we've replaced `sudo` with OpenBSD's `doas` for users of the `secure-node.nix` template.
|
|
|
|
|
It has greatly reduced complexity and is therefore less likely to be a source of
|
|
|
|
|
severe vulnerabilities in the future.
