同事寫的auto ssh login script:
#!/usr/bin/expect -f
# by gwang
# default password list
array set passwd {
0 "password1"
1 "password2"
2 "password3"
}
# try login
spawn $env(SHELL)
match_max 100000
send -- "ssh -p $port $user@$ip\r"
foreach i [array names passwd] {
expect {
"(yes/no)" {
send -- "yes\r"
exp_continue
}
"password:" {
send -- "$passwd($i)\r"
}
"Last login" {
break
}
}
}

由于ssh client默認支持的密碼錯誤重試是3, 所以這里只支持3個備選密碼。
Google for "ssh client password retry" and find link which could help:
ssh login retry 介紹了只要修改ssh client配置文件里/etc/ssh/ssh_config的NumberOfPasswordPrompts選項就可以了。無需重啟sshd...
