Autologin Expect scripts for telnet/ssh

Tired of typing over and over  your username/password when using
telnet/ssh ? Here are Expect http://expect.nist.gov/ scripts to autologin by Telnet and ssh
Notes:
- Yes, it is not secure to keep you username/password saved somewhere, so know
what you do . In my opinion  as long as this
is a dedicated for remote logins server, that has no access from outside, and hardened accordingly
(pertinent to the scripts – only owner/root can read user’s home folder, etc.,) the risk is acceptable.

Note 2: password is saved in a file named “sword”

cat tel
#!/usr/local/bin/expect   Change to the location of your Expect package
 
proc Usage {} {
  puts “\n tel <equipment to enter> \n”
  return
            }
 

set  argnumber  [llength $argv]
 
if {$argnumber==0} {
      puts “You need to specify at least one piece of equipment to log into\n”
      Usage
      exit
 
   }  elseif {$argnumber>1}  {
       puts “You specified too many arguments, only one please\n”
 
      Usage
       exit
                  }
 
set hostName [lindex $argv 0]
 
 puts “Entering $hostName”
 set username “myusername”
 set HANDL [open "sword"]
 set password [gets $HANDL]
 close $HANDL
 spawn telnet $hostName
 expect {[Uu]sername*} {
  send “$username\r”
 }
 
 expect {[Pp]assword:} {
 send “$password\r”
 }
 

#Cisco specific block – to enter enable level, you may remove this block if not needed
 expect {*#}  {
 send “enable\r”  }
 
 expect {[Pp]assword:} {
 send “$password\r”
 }
 #End of Cisco specific block

 interact
 

Now SSH login script
> cat essh
#!/usr/local/bin/expect   Change to the location of your Expect package
 
proc Usage {} {
  puts “\n essh  <equipment to enter> \n”
  return
            }
 

set  argnumber  [llength $argv]
 
if {$argnumber==0} {
      puts “You need to specify at least one piece of equipment to log into\n”
      Usage
      exit
 
   }  elseif {$argnumber>1}  {
       puts “You specified too many arguments, only one please\n”
 
      Usage
       exit
                  }
 
set hostName [lindex $argv 0]
 
 puts “Entering $hostName”
 set username “myusername”
 set HANDL [open "sword"]
 set password [gets $HANDL]
 spawn ssh $hostName
 
 expect {[Pp]assword:} {
 send “$password\r”
 }

#Again goes Cisco – specific block , remove if not needed
 expect {*#}  {
 send “enable\r”  }
 
 expect {[Pp]assword:} {
 send “$password\r”
 }
 #End of Cisco – specific block
