Return information about the server.
The System property returns information about the server
operating system. This is a read-only property that can be used
by the application to identify the type of server that the client has
connected to. Reading this property will cause the SYST command to be
sent to the server and will only return a useful value after a
connection has been established with the server.
By convention, the first whitespace separated token in the string
identifies the general operating system platform. For example, here
are some strings commonly returned by various FTP servers:
|UNIX Type: L8
||A standard UNIX based server. This is the most common value
returned by servers, and this indicates that the server
supports UNIX file naming and directory listing conventions.
This string may also include additional information such as the
specific variant of UNIX and its version. The L8 portion of the
string is a convention that lets the client know that a byte
consists of 8 bits.
|Windows_NT Version 5.0
||A standard Windows based server, typically part of Internet
Information Services (ISS). The server will use Windows file
naming and directory listing conventions. The version
identifies the specific release of Windows. For example,
version 4.0 specifies Windows NT 4.0 and 5.0 specifies Windows
|VMS V7.1 AlphaServer
||A server running the VMS operating system. The server will
use the standard file naming and directory listing conventions
for that platform. Note that it is possible that a VMS system
may also be configured to operate in a UNIX emulation mode, in
which case it will return UNIX instead of VMS.
|NetWare system type
||A server running the NetWare operating system. The server
will use the standard file naming and directory listing
conventions for that platform. Note that it is possible that a
NetWare system may be configured to operate in a UNIX emulation
mode, in which case it return UNIX instead of NetWare.
|WORLDGROUP Type: L8
||A server running the WorldGroup software on the Windows
platform. This server supports UNIX file naming and directory
listing conventions. WorldGroup is a collaborative workgroup,
email and file sharing service which includes an FTP
