;; This will allow eshell to autocomplete SSH hosts from the list of
;; known hosts in your ~/.ssh/known_hosts file. Note that newer
;; versions of ssh hash the hosts by default to prevent Island-hopping
;; SSH attacks. (
;; You can disable this by putting the following line in your ~/.ssh/config
;; file following the "Host *" directive:
;; HashKnownHosts no
;; Note that this will make you vulnerable to the Island-hopping
;; attack described in the link above if you allow key-based
;; passwordless logins and your account is compromised.
