He then has access to a special directory hierarchy containing the publically accessible files, typically in a subdirectory called "pub". This is usually a separate area from files used by local users. A reference like ftp: euagate.eua.ericsson.se /pub/eua/erlang/info means that files are available by anonymous FTP from the host called euagate.eua.ericsson.se in the directory (or file) /pub/eua/erlang/info. Sometimes the hostname will be followed by an Internet address in parentheses. The directory will usually be given as a path relative to the anonymous FTP login directory.
