Connecting To An External Network Using A logical (PACKAGE) IP Address
Hie everyone,
I am currently facing a problem whereby I can not connect to an external network from a package ip address on a HP-UX cluster. Below is the illustration:
Primary Server IP Address : n.n.n.202
Secondary Server IP Address : n.n.n.212
Package IP Address : n.n.n.211
Exterternal IP Address to connect to : x.x.x.1
When I try to connect to the external IP the IP for the Primary Server is the one being recognised instead of that of the package from which the application is running.
Question
Is there a way of overiding the system so that it can use the package ip address to connect to the external network rather than the system using the ip of the primary server upon which the package is running?
Cheers

ssh-http-proxy-connect
ssh-http-proxy-connect(1) User Commands ssh-http-proxy-connect(1)
NAME
ssh-http-proxy-connect - Secure Shell proxy for HTTP
SYNOPSIS
/usr/lib/ssh/ssh-http-proxy-connect [-h http_proxy_host] [-p http_proxy_port] connect_host connect_port
DESCRIPTION
A proxy command for ssh(1) that uses HTTP CONNECT. Typical use is where connections external to a network are only allowed via a proxy web
server.
OPTIONS
The following options are supported:
-h http_proxy_host Specifies the proxy web server through which to connect. Overrides the HTTPPROXY and http_proxy environment vari-
ables if they are set.
-p http_proxy_port Specifies the port on which the proxy web server runs. If not specified, port 80 is assumed. Overrides the HTTP-
PROXYPORT and http_proxy environment variables if they are set.
OPERANDS
The following operands are supported:
http_proxy_host The host name or IP address (IPv4 or IPv6) of the proxy.
http_proxy_port The numeric port number to connect to on http_proxy_host.
connect_host The name of the remote host to which the proxy web server is to connect you.
connect_port The numeric port number of the proxy web server to connect you to on http_proxy_host.
EXAMPLES
The recommended way to use a proxy connection command is to configure the ProxyCommand in ssh_config(4) (see Example 1 and Example 2).
Example 3 shows how the proxy command can be specified on the command line when running ssh(1).
Example 1: Setting the proxy from the environment
The following example uses ssh-http-proxy-connect in ssh_config(4) when the proxy is set from the environment:
Host playtime.foo.com
ProxyCommand /usr/lib/ssh/ssh-http-proxy-connect
playtime.foo.com 22
Example 2: Overriding proxy environment variables
The following example uses ssh-http-proxy-connect in ssh_config(4) to override (or if not set) proxy environment variables:
Host playtime.foo.com
ProxyCommand /usr/lib/ssh/ssh-http-proxy-connect -h webcache
-p 8080 playtime.foo.com 22
Example 3: Using the command line
The following example uses ssh-http-proxy-connect from the ssh(1) command line:
example$ ssh -o'ProxyCommand="/usr/lib/ssh/ssh-http-proxy-connect
-h webcache -p 8080 playtime.foo.com 22"' playtime.foo.com
ENVIRONMENT VARIABLES
HTTPPROXY Takes the http_proxy_host operand to specify the default proxy host. Overrides http_proxy if both are set.
HTTPPROXYPORT Takes the http_proxy_port operand to specify the default proxy port. Ignored if HTTPPROXY is not set.
http_proxy URL format for specifying proxy host and port.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
1 An error occurred.
