![]() So it gets a NXDOMAIN when trying to lookup newname and this error pops out. (My guess, based on experience, would be that when you changed the IP address and/or hostname of your current host, but you neglected to update /etc/hosts and/or didn't add a DNS entry for your new FQDN in whatever DNS server your network considers authoritative in this manner. This package is ESM only but it was tried to load by. That said, being unable to look up its own name may not be a security issue by itself, but that is a thing it should be able to do, and it would be wise to try and find out why it can't, just in case the error is masking a bigger problem. When importing a ESM only package by require, the following error happens. Pues tiene que haber una entrada con ese valor en el archivo de hosts a la IP de localhost. El caso es que ahí debería aparecer 'myhost' (o lo que te ponga después de 'unable to resolve host'. ![]() So you're very likely safe - as far as sudo is concerned, at least. Puedes editar ese nombre de la máquina con el comando: sudo vim /etc/hostname. Note that, like most security conscious software, sudo fails safe - if it can't look up the host, any entry that specify a host value is considered invalid. However, because that component still exists, sudo does a lookup for the current hostname to see if it may or may not match against any hypothetical entries in the sudoers file that might tell it whether or not to permit this sudo attempt. This has mostly fallen into disuse these days, but it was a way to keep the same sudoers file identical across multiple servers without having to tweak it for every single host.
