To login to the antenna computer over the network, you have to use a secure shell (SSH2) client. For example, to login from hapuna (Sun workstation in the control room), type:
hapuna% ssh -l cso 128.171.86.90 cso's password: ****** Authentication successful. hau$
where cso is the user name for general use of the antenna computer. A password of the week can be found in the control room. If it is missing, please ask me.
Note that only the SSH version 2.0 protocol is supported. Connections using SSH version 1.x only clients (e.g., FISH on alpha1) will fail. Also, the host you are trying to connect from must be known by the antenna computer. Among the computers on the summit network, hapuna, kilauea (Sun workstations), and ahi (IBM PC) have a SSH2 client, and are trusted by the antenna computer.
The antenna computer's debug port (i.e., the console port) is connected to the serial port A of hapuna (/dev/term/a). Terminal emulators, such as kermit, can be used to access the antenna computer via the console. To establish a connection using kermit, type:
hapuna% kermit C-Kermit 7.0.195 Beta.05, 21 Mar 1999, for Solaris 2.6 Copyright (C) 1985, 1999, Trustees of Columbia University in the City of New York. Default file-transfer mode is AUTOMATIC Type ? or HELP for help. C-Kermit>set line /dev/term/a C-Kermit>connect Connecting to /dev/term/a, speed 9600. The escape character is Ctrl-\ (ASCII 28, FS) Type the escape character followed by C to get back, or followed by ? to see other options. ---------------------------------------------------- [RETURN] user name:root password:****** Lynx Real-Time Systems, Inc.
