You can automate the login procedure for hosts connected by TELNET and rlogin sessions. When the session is established, the Operations Sentinel server receives messages that request a user-id or login, and a password. You can define a pattern to match these system messages and automate the sending of a command to the host with the user-id or login, and password. For multiple hosts that have different user-ids, logins, and passwords, you can use a hostid token as part of the message-matching criteria to send the correct login information, as explained in 7.2.2.
