Linux uses expect scripts to automate remote machine logon

First create a expect script ssh_expect with the following file contents:

#!/usr/bin/expect-fSethostname [lindex$argv 0]SetUser [lindex$argv 1]Setpasswd [lindex$argv 2]SetTimeout -SetForce_conservative1if{$force _conservative} {SetSend_slow { -.1}}spawn SSH$user@$hostname; expect {"*continue connecting (yes/no)?"{Send- S "Yes\r"; Exp_Continue}"*assword:"{Send- S "$passwd\ r"; }}interact

Then define some command aliases, such as:

alias   h101=‘ssh_expect 192.168.0.101 <user> <password>‘alias   h102=‘ssh_expect 192.168.0.102 <user> <password>‘

These aliases can be written to the ~/.BASHRC file.

Then execute h101 to automatically log on to the 192.168.0.101 machine.
