Ubuntu :: Bash Script With Expect - Headers ?
Jul 6, 2011
I have a script which uses a function and also uses expect.
If I have #!/bin/bash as the first line, the function is recognised. The expect calls are not, failing first with spawn.
If I have #!/bin/expect as the first line, the expect and spawn work fine. The function is not recognised.
My friend Google brings up examples with both these lines one after another in script files, just like Im doing. Except for me it doesnt appear to work.
Where am I making my beginners mistake in not understanding how this works ?

I am trying to make a script that can be used to check server load on a remote server and produces sound on our local machine, when server load exceeds a particular limit.1. I want to execute command uptime or uptime | awk '{print$10}'on the remote server and store the result in a variable(say x), and later use it in the bash script.
Bash Part
#!/bin/bash
x=$(/root/Desktop/exp)

I have searched and searched and maybe I don't know how to articulate this issue with out just posting the problem I'm having. Every time I bring up a terminal window I get the following "Header"
declare -x COLORTERM="gnome-terminal"
declare -x CPLUS_INCLUDE_PATH="/usr/lib64/qt/include"
declare -x DBUS_SESSION_BUS_ADDRESS="unix:abstract=/tmp/dbus-xSFd6zqrYQ,guid=dc5e07974559da016842742900000090"
declare -x DISPLAY=":0.0"

To be honest I cheated and used the .bashrc / .profile files from Ubuntu and all was working fine for a while now and it seems something changed to cause this... any ideas on why I am getting this? I checked my .bashrc and my /etc/profile and it doesn't look like anything is amiss..

I am trying to embed expect in my bash script to perform some tasks
USER="username"
PASS="password"
NAMES=`cat full_list`
for i in $NAMES
do
echo $i
[Code]....
The script initially reads a files containing a list of rpm's on each line and then spawns the rpm2ipc command which uploads the particular rpm to a repository. During this process it tries to enter the credentials, where it is failing.

I am writing an expect script. At a certain point there is a rule that produces this debugging output:
Code:
expect: does " Address or name of remote host [x.x.x.x]? " (spawn_id exp8) match glob pattern " Address or name of remote host [x.x.x.x]? "? no This just times out When I use -exact for the expect keyword it does work What am I doing wrong? THe first should also match in my opinion because it is equal as well. Even if I remove the I still have the same issue if I try without -exact. I don't understand. I tried removing the but still got the same.

Yesterday, I think I did something stupid: I removed kernel-headers, gcc, glibc-devel and glibc-headers. My box is a CentOS 5.4 webserver (it has loads of packages installed, but that was done through Virtualmin config, so it's quite coherent all in all). The thing is that now I need to reinstall at least the headers and glibc, but hey! this is what I get :

been a programmer for a while; on windows mostly but I'm starting to learn all that I can about linux software.I've picked up a funky little NAS which has ssh access to its (i believe uLinux) environment. I've also managed to find a compiler for it (gcc compiled for ARM - GNU/Linux).The plot thickens.I've had some headaches but I've now managed to compile Apache2 without DSO support... so far so good.In getting this far I've been told by a number of people i will need "the headers" specific to the device (the NAS didn't come with source code).
Since Apache 2 (without DSO) compiled fine I know i definitely have some headers. But DSO won't build with errors that lead me to believe it may be a header issue.The question:So i have some headers which educated guess work suggests to me that these are the headers for the std c/c++ libraries.finding "the headers" to know what they are the headers for

I'm using a small "expect" script to automate password entry for some file copying.The automation works fine, but the "Password: " prompt still displays on the screen. How do I hide the prompts so the user doesn't see "Password: " on the console?Here's the relevant section of my script:
Code:

I've got an Expect script that establishes a ssh connection to the iLO interface of a server. Problem is it drops me back to the local terminal and I can't enter commands to be executed on the remote host. How do I get it so it logs me into the server then leaves me connected to it?
Code:
expect -f - <<-expect_script_end
spawn ssh -o StrictHostKeyChecking=no $user@$host
match_max 100000
expect "*?assword:*"
send -- "$pass
"
send -- "
"
expect eof
expect_script_end
The ssh server running on the iLO interface appears to be sending eof's which is causing expect to exit. How can I get it to ignore them?

Here's my code...
But this gives an error

I think this is because of /

I'm using expect to log into a remote server and run a script. I want to able to have expect edit the output from that script, on the remote server, in VI. Has anyone ever done this before, it seems as though the expect interpreter has nothing to expect once VI is started, the file pointer starts at the beginning of the line, and expect usually reads the characters before the pointer.
spawn ssh user1@$remote_server
expect "password: "
send "$password

I am moving my migration forward and am trying to get my expect scripts tested and found one that no longer works. Quite simply, it spawns a telnet session to a router.
#!/usr/bin/expect
set env(TERM) vt100
set timeout 3
set send_human {.1 .3 1 .05 2}
set timeout -1
#
spawn telnet 10.254.3.232
and that's it. The result of the script is that the command to spawn simply shows up on the screen like it is a puts command. On my older openSUSE system, it worked fine. I am running Ubuntu v9.10 desktop, and expect and its libs are patched to the latest rev, expect is 5.43.0.

I wrote an expect script that tests user authentication against a RADIUS server. The username is an email address, including an @ sign. I recently wrote an HTML/PHP front end to allow others to input username/password into a form and then see the results when they hit submit. Expect code that takes two args username, and password
Code:
expect "#"
send "test aaa group radius [lindex $argv 0] [lindex $argv 1] new-code
"expect "#"
[code]....
Every works as it's supposed to, except for the output of the script. When it displays on the webpage, it's segmented weirdly with all throughout. What I've found is when I remove the @ sign in the username input, it fixes it. Is there any part of HTML or PHP that treats the @ as a special character? 1 more thing is that I have another HTML/PHP/EXP script that works fine with the @.

I encountered a doc file recently that opened noticeably differently in OOo than it did in MS Office. I think the difference was a small change in spacing that pushed some text onto the next line. It's also feasible that the problem was on my end. My question has this.
1. Should I expect OOo compatibility with text-only .doc files to be absolutely, 100% perfect?
2. If not, any insights on where the problems usually are?

Is there a similar thing in expect, as there is 'read'(Read a line from standard input) in bash?I mean one could easily construct following script in bash:
Code: > cat script.sh
#!/bin/bash
read -p "Username: " uname

We have a vendor supplied device that requires user interation, so we are using expect to automate the process. unfortunately the vendor may change the prompts as we take patches, which breaks our expect script. What I need to do is find a way to evaluate whether or not the prompt expect receives matches and if it doesn't I want the script to exit and throw an error. Currently it times out and then moves on to the next prompt.
How do I make my expect script exit if the prompt doesn't match?

I am having some difficulties with an expect script. What I want is that as soon as expect sees a newline followed by a dollarsign ($), that interact is done. So I would expect something like this to work:
Code:
"
$" { interact }
However it doesn't.
This is debugging output:

expect: continuing expect
expect: does " " (spawn_id exp6) match glob pattern "#"? no

just as an excercise I'm trying to write a script that would automaticly install java using an expect script.I create the expect script with autoexpect and it works. But only if I don't change the size of the window. It always hang at the line with "--More--". So I changed the script and it boiled down to this
Code:
set force_conservative 0 ;# set to 1 to force conservative mode even if
;# script wasn't run conservatively originally

I'll post the entire code here, and then specifically highlight what is just failing in a fashion I'm apparently incapable of fixing a few hours later:
Code:
#!/usr/bin/expect
# The script should be called with a file in the directory called sshServerList
# That file has the following format:
# Line # | Contents of line
[code]....
I've had all kinds of different results and problems, but I've never been able to successfully log into multiple servers, though the first server in the list most times works okay (though might not on this iteration). I'm a bit hack and slash and I would be very greatful not only for a solution, but any tips on how I should have done this and places where I could clean up my code.

I want to write a function in expect/tcl which logins into a router. but the syntax is a little confusing .
case 1: router prompts for "username".. {we put in username and password .. if they are incorrect we try with another username and password. if we succeed into getting a prompt we return 1 .. if both username passwords are wrong or we time out we return 0 }
case 2: router prompts for "login" .. {we put in username and password .. if they are incorrect we try with another username and password. if we succeed into getting a prompt we return 1 .. if both username passwords are wrong or we time out we return 0 }
case 3: router prompts for "password" only .. { we login just using the password and get to the enable prompt}
