expect giving problem

prasad_15 — Thu, 05 Jun 2003 16:44:32 GMT

Anybody can send me a expect script for logging into the system.
this following script is failing

set username testuser
set oldpasswd tesyy344
set newpasswd 1Xe7tfyz
set timeout_org $timeout
set timeout 3

set prompt "(%|#|\\\$) "

spawn rlogin -l $username localhost

expect "assword: " {
send "$oldpasswd\r"
} timeout {
set timeout $timeout_org
send_user "Time Out\n"
exit
}

Any suggestions !

Expect inclues a number of examples. The README file in the example directory contains a complete list as well as full explanations about each of the examples. The example called "passmass" logs into another system and changes the password. You can probably modify this for your requirements.

The README file in the distribution also describes the locaton of the Expect archive which holds even more scripts.

http://expect.nist.gov/FAQ.html
is the url for the expect FAQ

http://expect.nist.gov
is the url for the expect home page.

the home page includes links to the examples that are included with expect.

Here is a script I've used many times... it works perfectly.. you need to edit you username and password.

if {[llength $argv] != 1} {

}

set prompt "(%|#|\\$) $" ;# default prompt
catch {set prompt $env(EXPECT_PROMPT)}

set timeout -1
eval spawn rlogin $argv
expect eof exit -re $prompt

set env(DISPLAY) "[exec hostname].[exec domainname]:0.0\r"
}
send "setenv DISPLAY $env(DISPLAY)\r"

just a note... the script i attached was made using autoexpect from my linux box. autoexpect comes with expect....

type:

autoexpect -f telnet servername

then commense to logging in and doing your thing. when you hit ^d (control d) it writes to . you will then need to do some editing of the file and remove the datestamp and a few other lines... use my script attached in my earlier message as an example.

Hi All,

Finally what I was able to do is as below.
It takes both cases
1- when the password expires
2- whenever you need changing the password

Any suggestions to improve this.

#!/usr/local/bin/expect -f
#

#USAGE big_exp.exp [host] [username] [oldpw] [newpw]

set host [lindex $argv 0]
set username [lindex $argv 1]
set oldpw [lindex $argv 2]
set newpw [lindex $argv 3]

set pw_stat 0 ;# set to 1 for expired passwords

log_file /tmp/JUNK

set force_conservative 0 ;# set to 1 to force conservative mode even if
;# script wasn't run conservatively originally
if {$force_conservative} {
set send_slow {1 .1}
proc send {ignore arg} {
sleep .1
exp_send -s -- $arg
}
}

set timeout -1

spawn rlogin $host -l $username
match_max 100000

expect {

-exact "Password: " {
send "$oldpw\r"

send "$newpw\r"
send "passwd $username\n"
expect "password:"
send "$oldpw\r"
expect "password:"
send "$newpw\r"
expect "password:"
send "$newpw\r"
}
-re "expired" {
send "$oldpw\r"
send "$newpw\r"
send "$newpw\r"
}
}

send "exit\n"
send "exit\n"
expect eof

Thank You All.
