expect script + expect miss the send string + delay issue

view full story
linux-howto

http://serverfault.com – I write the active.ksh script (based on expect) in order to login automatically to some Solaris machine and execute the hostname command (login to virtual IP in order to verify which hostname is the active machine - I have two cluster solaris machines ) The problem is with expect; expect sends the password string (pass123) and it misses the Password question, and it still waits for the password. So actually the password (pass123) was entered after password question. On most cases the expect script works fine but sometimes it missed the password. EXAMPLE OF THE PROBLEM ./active.ksh spawn (HowTos)

grep output of expect script 23 weeks 17 hours ago

I'm trying to run some expect language, and grep/parse the output all in one script.

Hello All,

I am writing an Expect Script to execute some commands over ssh then exit the script. The script works just fine if I automate everything and assuming the correct password was entered.

So this Expect Script gets executed from a Bash script...

is it possible in expect script 3 years 22 weeks ago

I created a script wherein it will change password of a user

Quote:

#!/usr/bin/expect

spawn passwd [lindex $argv 0] set password [lindex $argv 1] expect "New UNIX password:" send "$password\r" expect "Retype new UNIX password:" send "$password\r"

Hi. Here is beginning of my script

Code: #!/usr/local/bin/expect -- set timeout 15 spawn /usr/local/account.sh -n modify expect "Password:" {send "mypassword\r"} But due to some terminal control sequences (or something else, dunno exactly) my password prompt is looking like this:

Code: [[61;157R-n Password: and expect doesn't recognize it.

I am trying to build and expect script to log into multiple aix boxes and change password.

I am building a simple ssh login wrapper tool to help auto login to one of hell lots of servers. It first takes descriptions from user input and then extract the corresponding (most relavant) server ip and password stored safely somewhere, using which it synthesis a piece of expect script.

Shell Scipt: temp.sh <code> su - <$username> expect pass.exp <code>

Expect script: pass.exp #!/usr/bin/expect -f # Login ####################### expect "Password: " send "<$password>\r"

it comes up with Password: but doesnt take password passed throguh file.

The target of the following simple expect script is to get the hostname name on the remote machine

Sometimes expect script fail to perform ssh to $IP_ADDRESS ( because remote machine not active , etc )

so in this case the expect script will break after 10 second (timeout 10) , this is OK but......

There are two options

Expect script perform ssh successfully , and performed the command hostnam
