Chapter 19. Client SOCKS Support
AS/400 client SOCKS support enables programs that use (AF_INET
SOCK_STREAM) sockets to communicate with server programs that run on
systems outside a firewall. In addition, by using client SOCKS support, both AS/400
FTP and AS/400TELNET client connections can be directed through a firewall. The
key advantage to AS/400 client SOCKS support is that it enables client applications
to access a SOCKS server transparently without changing any client code. AS/400
client SOCKS support operates with any SOCKS server that supports Version 4
SOCKS protocols.
For information on AS/400 client SOCKS support and SOCKS server concepts, see
the
Sockets Programming
, SC41-5422-03 book. For instructions on how to
configure your SOCKS server on the AS/400 firewall or for information on firewall
concepts, see the
Getting Started with IBM Firewall for AS/400
, SC41-5424-02 book
or go to http://www.as400.ibm.com/firewall.

Accessing SOCKS Functions through Operations Navigator

For information on how to configure an AS/400 host to use a SOCKS server,use
the AS/400 Operations Navigator.Define the client SOCKS configuration entries
that you need by using the SOCKS tab found under the Operations Navigator
function of Client Access/400 for Windows 95/NT.The SOCKS tab has substantial
help for configuring the client system for AS/400 client SOCKS support.
Toaccess SOCKS server functions through Operations Navigator, perform the
following steps:
1. Double-click your AS/400 server in the main tree view of Operations Navigator.
2. Double-click Network.
3. Double-click Protocols.
4. Double-click TCP/IP.
5. Click the SOCKS tab.
