Serial/AUX>Physical Ports>General>Terminal Server Profile Connection ProtocolsWhen a dumb terminal is connected to the console port on a device, a Terminal Server (TS) profile must be defined for the serial port using values you supply in the serial port configuration screens. Selecting the appropriate connection protocol on the Configuration>Serial/AUX>Physical Ports>General Screen is part of defining the TS profile. An administrative user can configure serial ports to support dumb terminals in the following two ways:
• Dedicate a dumb terminal to access a single remote server by means of either telnet, one of two ssh versions, or raw socket connections.
• Enable a dumb terminal to access multiple servers and perform any other desired actions through the OnSite.The TS profile must specify the terminal type, the desired connection protocol, the TCP port number, and the IP address for the remote host (for dedicated dumb terminals). When the user turns on a dedicated dumb terminal, the OnSite starts a session using the specified connection protocol. For example, if “Telnet” is selected as the connection protocol, when the dumb terminal is turned on, the OnSite automatically starts a telnet session on the specified host.The following table describes the connection protocols that can be selected if a dumb terminal is connected to the selected serial port. When you choose one of the dumb terminal connection protocols, TS profile-specific fields appear on the “Other” screen, which you also need to fill out.
Protocols for Dumb Terminals Connected to Serial Ports Dedicates a dumb terminal that is connected to the selected serial port to access a specific server using the telnet protocol. When the attached dumb terminal is turned on, the OnSite opens a telnet session on the server, whose IP address you need to specify on the “Other” screen. Dedicates a dumb terminal that is connected to the selected serial port to access a specific server using the ssh v1 protocol. When the attached dumb terminal is turned on, the OnSite opens a SSH version 1 session on the server, whose IP address you need to specify on the “Other” screen. Dedicates a dumb terminal that is connected to the selected serial port to access a specific server using the ssh v2 protocol. When the attached dumb terminal is turned on, the OnSite opens a SSH version 2 session on the server, whose IP address you need to specify on the “Other” screen. Dedicates a dumb terminal that is connected to the selected serial port to connect to the OnSite. When the attached dumb terminal is turned on, the OnSite opens a telnet session on itself. The user then can use any of the OnSite’s Linux commands. An administrative user can also create a Terminal Profile menu (under Access>Terminal Profile Menu in Expert mode) that enables the user to quickly launch sessions on any number of remote hosts. Dedicates a dumb terminal that is connected to the selected serial port to access a specific remote host using the raw socket protocol. When the attached dumb terminal is turned on, the OnSite opens a raw socket session on the host using an IP address and TCP port number you must specify on the “Other” screen.
