Some stuff that, I never rember where it is

Ldap: internal2 (cname ldap.orbit-lab.org) - The ldap conf lives in etc, as well as the "secret" Web: served out of external3 (cname www.orbit-lab.org) - External web huhah only. Internal ldap admin: ​http://internal3/phpldapadmin - If you just point a web browser to internal 3, it enumerates /, but that directory doesn't show up. however point the url directly works.
