2.0.11 REPL server listens on 127.0.0.1 but not "localhost" |

After starting 'guile --listen', I can connect to it via 127.0.0.1 but
not "localhost": "Ncat: Connection refused." I don't know if
listening on "localhost" by default has any security implications?

I don't have access to the exact system anymore since it's been more than
6 years, but on a Debian with the exact same /etc/hosts I can't reproduce
the issue anymore. Since I was apparently the only one who could repro it
in the first place, I'm closing it now. :-)

Maybe that was the case on that system for some reason, despite the IPv4
address being on top in /etc/hosts and nslookup giving 127.0.0.1.
Maybe it was even a bug with the ncat I had installed, who knows.
