SSH Login Script

smekkley

Bash(expect) script to login remote machines via ssh.
Append -L:”local port”:”Remote host”:Remote port” to do port fowarding.
Associate sh files with /bin/mintty.exe if you are using cygwin.

To one host
#!/bin/bash

host=host
name=hostname
user=user
pass=pass
log=/cygdrive/c/Users/Public/logs/"$name"_`date +%d_%h_%Y_%H%M%S`
noansi=/cygdrive/c/Users/Public/script/no_ansi.pl

expect -c "
spawn ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null-l $user $host
expect password:
send $pass\n
interact
" | tee -a "$log"_raw.txt
perl $noansi "$log"_raw.txt > "$log".txt

Send commands to more than one host(telnet)
#!/bin/bash

hosts="host host1 host2"
user=user
pass=pass

for host in $hosts; do
expect -c "
spawn telnet \"$host\"
expect login:
send \"$user\n\"
expect Password:
send \"$pass\n\"
expect $
send \"ping 10.0.0.1\n\"
expect $
send \"exit\n\"
