更好的自动ssh登录

更好的自动ssh登录

解决~/.ssh/known_hosts 过期问题。
bash + expect

bash：ssh.sh

1. #!/bin/bash
2. help(){
3. echo "usage: [password]"
4. }
5. [ -z "$1" ] && { help; exit 1; } || {
6. case $1 in
7. -*) help; exit ;;
8. *) ip=$1;;
9. esac
10. }
11. shift
12. ssh.exp "$ip" "$@"
13. [ "$?" = "1" ] && ssh-keygen -R $ip && ssh_ivie.exp "$ip" "$@"

expec
ssh.exp

1. #!/usr/bin/expect -f
2. proc help {} {
3. puts {usage: <ivie_ip> [password]}
4. }
5. if {$argc<1} { help ; exit}
6. set ip [ lindex $argv 0 ]
7. set password rootroot
8. if {$argc==2} { set password [lindex $argv 1] }
9. # close the output
10. log_user 0
11. set timeout 30
12. spawn ssh -XY root@$ip
13. expect {
14. -re ".*:~ # " {}
15. "Password: " { send "$password\r" }
16. "(yes/no)?" {send "yes\r"; exp_continue}
17. "Host key verification failed" { send_user "run: ssh-keygen -R $ip" ; exit 1 }
18. timeout {puts "check your ip: $ip"; exit 2}
19. eof { puts "check your ip: $ip" ;exit 3 }
20. }
21. interact

我测试过在一个expect中完成，但是没有成功。还望有谁能够完成，给予指教。
