It tests if the value in $_ (which is the default if no other value is
specified) matches the regular expression between the /.../, which in
turn specifies that the string should begin with whatever value the
element "server" in the hash %hash currently has.
If a match is found, then it assigns the text "not accessible" to the
variable $name.
