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.
SSL/TLS
In
Installation
Manager,
click . Select
Nonsecure
SSL Mode to accept a 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 selected, 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 . Select 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.
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
Host. When the SOCKS proxy port field is empty, you see
the message Port range is [0,65535]. Enter the
value 0 when you do not want to specify a port number.
HTTP Proxy

Installation
Manager,
click . Use this option to enable an HTTP or SOCKS proxy.
- HTTP proxy: For an HTTP proxy server, do not check the option Use
SOCKS. You must enter values for the HTTP Proxy
host and Proxy port fields. The Proxy
port value must be 0 - 65535.
- SOCKS proxy: For a SOCKS proxy server, check the option Use
SOCKS. You must enter values for the SOCKS
proxy host and SOCKS proxy port fields.
The SOCKS proxy port value must be 0 - 65535.
You might see the message
Invalid Host after you
check the
Enable proxy server option. The message
shows 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

Enter the value 0 when you do not want to specify a port number.
The
