Erwarten: Verwenden Sie die Ausgabe von Remote-Befehl

Question

Ich bin neu zu verwenden erwarten, und ich habe eine Antwort auf die folgende Frage gesucht, aber noch nicht gefunden. Ich versuche, mich bei einem Server anzumelden und einen Befehl auf diesem Server auszuführen. Der Befehl gibt Text aus, einschließlich eines anderen Befehls, den ich ausführen möchte, und eines Passworts, das ich brauche.

z.

#!/usr/bin/expect -- 

<initialization of variables> 

spawn ssh $user@$host 
expect -re ".*sswor.*" 
send "$password\r" 
expect $prompt 
send $command 
expect magical stuff that I can use to create the next command 
send $next_command 
send $new_password 
<more stuff> 

Die Ausgabe von oben "$ Befehl senden" ist

-bash-3.00$ <command from send> 
Log into the next device by copying and pasting the following line: ssh new-user@new-host 

The password to login is: Ex17dsk5                   


-bash-3.00$ 

Nun, was ich brauche ist "ssh new-user @ new-Host" und "Ex17dsk5" und sie in $ zu packen next_command und $ new_password. Ich denke, ich muss expect_out (X, string) verwenden, wenn ich Ausdrücke anpasse, aber ich bin nicht in der Lage, herauszufinden, wie man alles macht.

Jede Hilfe wird sehr geschätzt.

Danke für den Tipp! Es funktioniert jedoch immer noch nicht, aber viel näher. Der Code, den ich zur Zeit verwendet, ist:

expect { 
       -re "Log into the remoteHost by copying and pasting the following line: ssh (.*)?\n?" {set remoteHostlogin "$expect_out(1,string)"; exp_continue} 
       -re "The password to login to the remoteHost is: (.*)\r\n"        {set remoteHostpassword "$expect_out(1,string)"} 
     } 

Mein Gedanke war, dass die? würde es nicht gierig machen. Es scheint jedoch zu dem letzten \ n im Puffer (siehe unten) zu passen. Und da es mit dem letzten \ n übereinstimmt, enthält expect_out (1, string) die Kennwortinformationen, die ich mit expect vergleichen möchte. Der Code erzeugt die folgende Debug-Info:

You must ssh to the remoteHost from one of the log servers. Login to either Log Server 1 or Log Server 2 before logging into the remoteHost. 
Log into the remoteHost by copying and pasting the following line: ssh 0005B9-cdmaremoteHost-0002F5007546@5.0.31.62                  
The password to login to the remoteHost is: B4dZsePI

EDIT

Danke Jungs für Sie helfen! Im Folgenden finden Sie, was schließlich für meinen Matching auf I angesiedelt: :

expect { 
       -re "Log into the remoteHost by copying and pasting the following line: (ssh .*\[0-9]+\.\[0-9]+\.\[0-9]+\.\[0-9]+)" {set remoteHostlogin "$expect_out(1,string)"; exp_continue} 
       -re "The password to login to the remoteHost is: (\[0-9a-zA-Z]{8})"       {set remoteHostpassword "$expect_out(1,string)"} 
     } 

Answer 1

einen Schuss des Geben. Verwenden Sie auch exp_internal 1 in Ihrem Skript, um die interne Diagnose zur Fehlerbehebung zu aktivieren.

expect -re "Log into the next device by copying and pasting the following line: (.*)\n" { 
    set loginstr "$expect_out(1,string)" } 
expect -re "The password to login is: (.*)\n" { 
    set passwordstr "$expect_out(1,string)" } 
send "$loginstr\r" 
expect "*?assword*" 
send "$passwordstr\r"
