Mail script

Braynid · 07-11-2006, 03:22 AM

With:

Code:

send "pass $PASSWORD\n"
expect {
  "+OK*\n"      {send_user "$expect_out(0,string)"}
  -gl "-ERR"    {send_user "Username or password incorrect.\n"}
}

I get:

Code:

root@MainThinkTank:~# bmail a b
send: spawn id exp6 not open
    while executing
"send "quit""

In other words, what i want do to is echo "User/pass invalid" if the expect "+OK" afer 'pass $pass' fails. But if the pass is invalid the 'expect "+OK"' fails and the script returns error message. Another thing, how can i use a line like:

Code:

/usr/bin/expect <<EOF | grep '+OK logged in.' >/dev/null && echo "User/pass corecte pe domeniu" | grep 'Connection closed by foreign host.' >/dev/null && echo "User/pass INCORECTE pe domeniu"

Thanks.

I don't know where that error message comes from, remove "log_user 0" from the script to see what's going on. As for the "other thing", that line doesn't make much sense. Use the send_user commands to modify the script's output.

I have no "log_user 0" in my script

So here's what i want to do:
1) telnet to host.com
2) send user $user
3) send pass $pass
if (user/pass correct) I) TRUE echo "User/pass correct"
II) FALSE echo "User/pass incorrect"

So how do i do that?

I'm now reading some information on expect but i really love some support, thanks for all the kind information you already give me.

P.S: The 'send_user' writes nothing on the screen.

That's strange, my last script should do precisely what you're asking for (except that its output looks a little different). Below you'll find that script's output with false user/password, once with "log_user 0" and then with "log_user 1". The send_user output is marked red, Expect's regular output is green.

Code:

ada@barnabas:~/tmp> ./test nobody unknown
Connection established.
Username or password incorrect.
ada@barnabas:~/tmp> sed -i 's/log_user 0/log_user 1/' test
ada@barnabas:~/tmp> ./test nobody unknown

Ok, i was trying to run it with 'function' in .bashrc !
I have added the following script in a separate file:

Code:

#! /bin/bash

LOGIN=$1
PASSWORD=$2

/usr/bin/expect <<EOF

log_user 0

spawn /usr/bin/telnet mail.rdslink.ro 110
expect {
  "+OK"         {send_user "Connection established.\n"}
  timeout       {send_user "Timeout.\n"; exit 1}
}

send "user $LOGIN\n"
expect {
  timeout       {send_user "Timeout.\n"; exit 1}
  "+OK"
}

send "pass $PASSWORD\n"
expect {
  "+OK*\n"      {send_user "\$expect_out(0,string)"}
      -gl "Connection closed by foreign host."    {send_user "Username or password incorrect.\n"}
}

send "quit"
EOF

Thanks for all the hints!!
Have a nice day!

That should still work. I just tried, and it gives the same result.
