EXPECT: Can not telnet/ssh to switches directly - Only one switch to others

Can not telnet/ssh to switches directly. Can only ssh into a ASR/switch then from the switch ssh to each switch.

ACL only allows ASR device to SSH to each switch.

This can be done with a for loop within the "expectscript.exp" script.

Create a file with the names/IP’s of the devcies you want to connect to from the ASR:

STEPS:

1. [root@localhost script]# vi device-list
    10.x.x.1
    10.x.x.2
    10.x.x.3
    10.x.x.4

2. [root@localhost script]# vi from-one-device-TO-ALL-others.exp

#!/usr/bin/expect -f

# Set variables - some of which were sent from the calling bash script

    set hostname [lindex $argv 0]
    set username "YOURUSERNAME"
    set password [lindex $argv 1]
    set enablepassword [lindex $argv 2]
    set timeout 5

# Where to put the Log file results
 log_file -a /root/script/results.log

    spawn ssh -o StrictHostKeyChecking=no $username\@$hostname
    expect "*assword: "
    send "$password\r"

# SSH to each IP/Hostname in local file named "device-list", do a "show clock", then exit

    set devicelist [open device-list]
    while {[gets $devicelist line] != -1} {
    expect "*>"
    send "ssh $line \n"
    expect "Password:"
    send "$password\r"
    expect "*>"
    send "show clock\n"
    expect "*>"
    send "exit\n"
    expect "*>"
    }
    close $devicelist

    send "exit\n"
    expect ":~\$"
    exit

3. Now RUN it:

[root@localhost script]# ./from-one-device-TO-ALL-others.exp
