Proxy servers enable connections to remote servers from
behind a firewall.
You can set preferences for proxy servers in IBM® Installation Manager or
in a response file. After the proxy server is enabled, the proxy
server is used for all server communications.
For information about authentication schemes, see Supported authentication schemes.
SSL/TLS
In
Installation
Manager,
click . Select
Nonsecure
SSL Mode when you want to accept any certificate when
an SSL connection is made.
Important: Accepted certificates
might include invalid or untrusted certificates. Use nonsecure SSL
mode only if you trust all the servers that Installation
Manager accesses.
When
nonsecure SSL mode is enabled, the
Session option
is checked by default. When the
Session option
is checked, nonsecure SSL mode is enabled only for this session of
Installation
Manager.
The next time
Installation
Manager is
started, nonsecure SSL mode is not enabled. When the Permanent option
is checked, nonsecure SSL mode remains enabled the next time you start
Installation
Manager.
FTP Proxy
In
Installation
Manager,
click . Enable this option to specify a SOCKS proxy host address
and a SOCKS proxy port number. The SOCKS proxy port value must be
0 - 65535. FTP proxy is an application-level gateway for FTP. The
FTP proxy functions between a client and a server, forwarding command,
and data streams. An FTP proxy also can fix connections to the FTP
server and helps provide proxy authentication.
Note: Both the SOCKS
proxy host field and the SOCKS proxy port field require a value. When
the SOCKS proxy host field is empty, you see the message Invalid

the message Port range is [0,65535]. Enter the
value 0 when you do not want to specify a port number.

You must enter values for the SOCKS proxy server and SOCKS proxy port
fields. The SOCKS proxy port value must be 0 - 65535.
Note: You might see the message Invalid Host after
checking Enable proxy server. The message displays when the Proxy
host field or the SOCKS proxy host field is empty. Enter information
into the field. The Proxy port field or the SOCKS proxy port field
must have a value. When you delete the value from the Proxy port field
or the SOCKS proxy port field, the message Port range is
