User guide

If the default value (443) is modified, the port number in the URL must be specified
when accessing the DSView 3 software. For example, if the IP address of the hub
server is 10.0.0.1 and the port number is changed to 444, https://10.0.0.1:444/dsview
must be typed in the Address field of the web browser to access the DSView 3
software.
The selected port must be available on the DSView 3 server. If DSView 3 software
clients are located on an external connection, the specified port must be open on the
firewall.
4. Click Save. A confirmation dialog box will appear.
A web browser error message will appear when Save is clicked. This error message is a
normal occurrence. To reestablish connection to the DSView 3 software, you must
reconnect to the hub server by typing the URL with the new port number. For
example, if you changed the port number to 334 for a hub server with an IP address of
10.0.0.1, type https://10.0.0.1:334/dsview to access the DSView 3 management
software.
5. Confirm or cancel the change.
Server certificates
DSView 3 software administrators manage server certificates. See Certificates on page 52 for a
description of certificate types and procedures to manage certificate policy and the system trust
store.
Security alerts
The DSView 3 software uses SSL (Secure Sockets Layer) to securely communicate between the
DSView 3 software hub server and DSView 3 software clients. SSL provides secure
authentication using certificates, which is data that identifies the PC with which
communication will occur. A certificate is typically verified by another certificate from a
trusted certificate authority.
When the DSView 3 software is initially installed, it generates a self-signed certificate for use
with DSView 3 software clients. To replace this, a DSView 3 software administrator may create
a Certificate Signing Request (CSR) to submit to a trusted third party Certificate Authority
(CA) for signature. The administrator may then replace the generated certificate with the new
one. If the generated certificate is not replaced, the web browser will prompt a user whether to
trust the generated certificate when a DSView 3 software client session is started.
Three tests are performed on a certificate each time a DSView 3 software client connects to the
DSView 3 software hub server:
• Does the client web browser trust the certificate issuer?
