Introduction 49
Port Access Prerequisites
Special circumstances may require OnSite administrators to configure TCP
port numbers different from the defaults. For example, a firewall may block
TCP port 5900 or 5901.
The OnSite administrator can assign a descriptive alias to each port to identify
the connected computer. For example, if a SunBlade server is connected to
KVM Port_3, the administrator could define Port_3’s alias to be “SunBlade,”
so “Port_3” is replaced in the ports list by “SunBlade.”
Note: The list of ports in the OSD displays only 19 characters. If anyone will
be using the OSD for KVM port access, keep this in mind. If longer aliases are
required at your site, put the information that uniquely identifies the server at
the beginning of the alias.
The following table provides links to procedures for changing default TCP
port numbers and port aliases.
