You should ask the other guys about their file permissions. If they
don't want to let you read those files, they should protect them.

The password cache is only for a given Emacs session, it doesn't
survive session end. Tramp has no own password handling mechanism, it
let the underlying programs (ssh, ftp, ...) do the job. If you want to
have a password-less ssh connection you should read about ssh-agent.

Not for this think. Adding the Perl path is useful at all for Tramp
operations.

Sorry, but here I am lost.

Could you, please, open "/address@hidden:/" and check in the
listing whether there is a directory "html"? If yes, check ownership
and access rights of that directory.

Recipe 2. describes your attempt with "~/.ssh/config" (you shouldn't
edit "/etc/ssh/ssh_config").

I guess you need it vice versa:

  Host test
       HostName hartford-hwp.com
       User usr1066

Then "/test:" would be sufficient, given that "ssh" is your default method.
