Configure a Proxy Server for Object Storage

If you must route your object storage server access through a proxy server, you must provide the following in a configuration file:

The host address information
(Optional) The authentication information

Caution: You must use a proxy server that does not require a Content-Length entity header when there is no POST data. Otherwise, your multipart upload requests fail.

Contact your system administrator to obtain the proxy-related configuration information, which includes:

The IP address
The port number and protocol (for example, HTTP or HTTPS) of the proxy server
The username and password required for access, if applicable

Configure the required environment variables in the /usr/cvfs/config/DSM_control.conf file.

Note: You must create the file if it does not already exist.

Environment Variable	Description
http_proxy	Set this variable to specify the IP address and port number of the proxy server. If you are using the HTTP protocol: http_proxy=http://proxy_ip:port export http_proxy If you require authentication: http_proxy=http://user:password@proxy_ip:port export http_proxy
https_proxy	Set this variable to specify the IP address and port number of the proxy server. If you are using the HTTPS protocol: https_proxy=https://proxy_ip:port export https_proxy If you require authentication: https_proxy=https://user:password@proxy_ip:port export https_proxy
no_proxy	By default, all object storage server access is routed through the proxy server, if it is configured. For communication within an internal network, you might prefer direct routing (for example, by-passing the proxy). You can do this by adding the proxy-exempt network/mask and host addresses to the no_proxy variable. For example, to enable direct routing for an internal network 10.65.0.0/16, set the no_proxy variable as follows: no_proxy=10.65.0.0/16,localhost,127.0.0.1 export no_proxy

Environment Variable

Description

http_proxy

Set this variable to specify the IP address and port number of the proxy server.

If you are using the HTTP protocol:

http_proxy=http://proxy_ip:port

export http_proxy
If you require authentication:

http_proxy=http://user:password@proxy_ip:port

export http_proxy

https_proxy

Set this variable to specify the IP address and port number of the proxy server.

If you are using the HTTPS protocol:

https_proxy=https://proxy_ip:port

export https_proxy
If you require authentication:

https_proxy=https://user:password@proxy_ip:port

export https_proxy

no_proxy

By default, all object storage server access is routed through the proxy server, if it is configured.

For communication within an internal network, you might prefer direct routing (for example, by-passing the proxy). You can do this by adding the proxy-exempt network/mask and host addresses to the no_proxy variable.

For example, to enable direct routing for an internal network 10.65.0.0/16, set the no_proxy variable as follows:

no_proxy=10.65.0.0/16,localhost,127.0.0.1

export no_proxy

After you configure the proxy variables, run the following command to restart StorNext:

DSM_control restart

Below is an example of DSM_control.conf configuration:

http_proxy=http://10.65.10.2:3128

no_proxy=10.65.0.0/16,localhost,127.0.0.1

export http_proxy no_proxy
