Configuring Printers with WebLink
Configuring Weblink
10/31/13 P1058563-003
• The proxy server port (optional)
• The username and password for the proxy (optional)
To supply the address of the proxy server (assuming a default port and no
username/password), configure the proxy setting as follows:
!U1setvar"weblink.ip.conn1.proxy""https://my.internal.proxy/"
In this scenario, the proxy address is my.internal.proxyand the scheme is HTTPS. The default
port (1080) will be used. No username or password will be used to authenticate with the proxy.
To specify an alternate port, configure the proxy as follows:
!U1setvar"weblink.ip.conn1.proxy""https://my.internal.proxy:3128/"
To specify a username and password configure the proxy as follows:
!U1setvar"weblink.ip.conn1.proxy""https://user:pass@my.internal.proxy/"
The proxy username, password, and the rest of the URL must follow the rules specified in
RFC3986 (
http://www.ietf.org/rfc/rfc3986.txt).
When HTTP Authentication is Necessary
Use this configuration when, for example, a firewall requires a username and/or password.
It may be necessary to specify a username and password to various routers and servers along
the path to the remote server. Typically, when using a browser to access the server, the
authentication request will be presented in the form of a dialog window that asks for the
username and password.
Because the printer’s connection to the remote server is headless and non-interactive, the
Weblink configuration allows a user to enter in a server name/username/password triplet. The
triplet will be used in the event that the printer is presented with an authentication request (for
example, this typically is requested via the
HTTP/1.1401Unauthorized request).
To specify authentication credentials, issue the following:
!U1setvar"weblink.ip.conn1.authentication.add""servername.comusername
password"
In this scenario, the server requesting authentication is servername.com. The username and
password to be supplied are ‘username’ and ‘password’. The server name can be either a DNS
name or an IP address. The username and password cannot be retrieved from SGD, SNMP, or
JSON once added. Only the server name will be returned.
More than one set of authentication triplets can be added. The printer will only use the
credentials as they are needed. In other words, the printer will only use the credentials for
servername.com if it receives a
HTTP/1.1401Unauthorized request from servername.com.
To see what authentication triplets are specified issue:
!U1getvar"weblink.ip.conn1.authentication.entries"
To remove authentication credentials issue the following:
!U1setvar"weblink.ip.conn1.authentication.remove""servername.com"
