sudo apt-get install expect
Login telnet :
#!/usr/bin/expect
spawn telnet 192.168.1.1
expect Login:
send root\r
expect Password:
send password\r
interact
tftpput :
#!/usr/bin/expect
spawn tftp 192.168.1.1
expect tftp>
send bin\r
expect tftp>
send "put $argv\r"
expect tftp>
send quit\r
interact
這樣使用 tftpput FILENAME
SSH LOGIN :
#!/usr/bin/expect -f
# Expect script to supply root/admin password for remote ssh server
# and execute command.
# This script needs three argument to(s) connect to remote server:
# password = Password of remote UNIX server, for root user.
# ipaddr = IP Addreess of remote UNIX server, no hostname
# scriptname = Path to remote script which will execute on remote server
# For example:
# ./sshlogin.exp password 192.168.1.11 who

# set Variables
set password [lindex $argv 0]
set ipaddr [lindex $argv 1]
set scriptname [lindex $argv 2]
set arg1 [lindex $argv 3]
set timeout -1
# now connect to remote UNIX box (ipaddr) with given script to execute
spawn ssh root@$ipaddr $scriptname $arg1
match_max 100000
# Look for passwod prompt
expect "*?assword:*"
# Send password aka $password
send -- "$password\r"
# send blank line (\r) to make sure we get back to gui
send -- "\r"
#expect eof
expect "#"
這樣使用 ./ssh.sh password ipaddr 解釋: expect "#": 結束expect 返回.
interact : 最後加這一行, 把控制權交給控制台，這個時候就可以手動操作了.
proc Login {username server password} {
set prompt "(%|>|\#|\\\$) $"
spawn /usr/bin/ssh $username@$server
expect {
-re "Are you sure you want to continue connecting (yes/no)?" {
exp_send "yes\r"
exp_continue
#continue to match statements within this expect {}
}
-nocase "password: " {
exp_send "$password\r"
interact
}
}
}
#!/usr/bin/expect
set timeout 1
set cmd {uname -a}
spawn ssh root@$argv
expect_after eof { exit 0 }
## interact with SSH
expect {
"(yes/no)?" {send -- "yes\r"; exp_continue}
"password:" {send -- "123456\r"}
}
expect "# "
send "$cmd\r"
expect "$cmd\r"
expect "(.*)\r"
send "exit\r
