I had run it with .pub-cache/bin/linkcheck http://myusername:[email protected] not knowing any other way to have it work with a site requiring Basic-Auth. Interesting that it ate the username before giving up looking for (I gather) a port number. This is the old, old URL format user:password@host[:port].
