How to revert the changes of dns agent?

[hinogi]

How can I let WSL2 generate the resolv.conf again?

Hi @hinogi

The main change is this option: generateResolvConf in /etc/wsl.conf, you need to revert this to true.

https://learn.microsoft.com/en-us/windows/wsl/wsl-config#network-settings

For reference this is the changes this tool makes:

wsl2-dns-agent/src/runner.rs

Lines 111 to 127 in 74e9723

	if needs_update {
	log::warn!("Updating {} for {}", WSL_CONF, distribution.name);
	config.set("network", "generateResolvConf", Some("false".to_string()));
	let new_conf = config.writes().replace("\r\n", "\n");
	distribution.write_file(WSL_CONF, &new_conf)?;
	// Distribution needs to be restarted to take effect
	distribution.terminate()?;
	}
	}
	// Replace the /etc/resolv.conf file
	// Removing read only is expected to fail if the file doesn't exist
	// Read only needs to be set because of bug:
	// https://github.com/microsoft/WSL/issues/6977
	distribution.set_read_only(RESOLV_CONF, false).ok();
	distribution.write_file(RESOLV_CONF, resolv)?;
	distribution.set_read_only(RESOLV_CONF, true)?;
