Using the ETS
Connecting to Services
6-5
If necessary, you can specify a login to an explicit port on the remote host by adding :xxxx to the end of the
hostname or IP address. For example, the following command attempts a Telnet connection to TCP port
2005 on the specified host, rather than the default Telnet port.
Figure 6-5: Specifying a Port Number
On some Telnet connections, padding of Newline characters may be a problem. By default, the ETS will
pad newlines with a Null character (ASCII 0x0) as part of the Telnet specification. Two commands are
provided to override this default: Set/Define Port Telnet Pad and Set Session Newline. Set Port Telnet Pad
controls whether a null character is sent after the newlines in an interactive session; Set Session controls
which character is actually sent as the newline character (usually a carriage return).
6.3.3 Connecting to Local Ports
Users can connect to local ETS ports. This is useful, for example, when configuring the unit from a serial
port. To connect to a local port from an ETS login, use the Connect Local command at the Local> prompt.
Figure 6-6: Connecting Locally
The connection will be made to the specified port provided that the port is available. Once the connection
is established, commands may be issued to the device attached to the serial port (such as a modem or
printer).
6.3.4 Connecting to Remote Hosts Via Rlogin
If Rlogin connections are enabled on both the ETS and the remote UNIX or VMS hosts, you can use the
Rlogin command to connect from the ETS to these hosts. Because Rlogin can bypass the normal password/
login sequence, it is a potential security problem and might not be enabled. The format of the Rlogin
command is identical to the Telnet command.
Figure 6-7: Rlogin Command
If Rlogin is enabled, your ETS username is used for the remote login. If the username is unknown or is
password protected, you will still be prompted for a login password on the UNIX host. If password
protection is turned off for the username entered, you will be logged in normally.
You can optionally specify a username to be used instead of the current one for your port.
