General :: Run Script From Another With Multiple User Inputs And Expect

Jun 5, 2011

I am literally bashing (pun intended) my head against the keyboard at this minute! I am trying to automate a script via cron for my centos server. The script requires two user inputs (e.g. read VAR). However, I do not want to edit the original file, as I would like to be able to run it normally as well. It is also made by someone else, and so if an update becomes available, it will be easier to install. My idea is that i create a cron script, to run this second script from, and the only way i could find was with expect. However I am having troubles, In order to test out expect, I have created the following:


It looks as if the second input is completely ignored ?! what i am doing wrong? or if there is a more elegant solution to running a script from a script with user inputs?

General :: Expect: Line Seems To Match Exactly However Expect Thinks Not?

Jun 16, 2010

I am writing an expect script. At a certain point there is a rule that produces this debugging output:


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.

"do something funny, using OpenFOAM"
cd system
sed 's/oldvalue/oldValue+increment/' -i sampleDict
cd ..

So basically, can you for instance create a constant "a" and increase it for every loop interval and use it for sed?

General :: Embed Expect In Bash Script

May 14, 2010

I am trying to embed expect in my bash script to perform some tasks

General :: Using The Expect And Send To Execute List Of Commands Inside A File?

Feb 2, 2011

i am working on some kind of PBX and i have list of telephone numbers inside a file, i have to insert these numbers into the correct command and then telnet to a remote server and execute these commands. i can read the telephone numbers and insert them into the command with no problem, but when i try to insert these commands into the send i face problem. here is the basic code

read msisdn < input


i can make external loop inside the Bash which read the input file and issue the command and then telnet and execute, but this will make the script connects and disconnects again for each line which cause high load on that server and hardwar problem. i am wondering if there is an option inside the expect interperter which makes the send read directly from a file... somthing like this:

expect "<"
send "input-filename
expect "<"
expect eof

Hardware :: Ps2 And Usb Ports Won't Recognize Inputs

Sep 19, 2010

He doesn't do anything except emails, Internet search and sort pictures and I don't think he or his wife do anything I haven't shown them. The computer is an older model but I'm unsure of the brand, the motherboard is Intel entry server S845WD1-E. Recently his mouse stopped working, then his keyboard. I am going to try a ps2 card (the ps2 is internal to board). We are unable to use a usb mouse or keyboard. I have installed a new usb card but that did not work. I've tried different memory but have not run memck on it with another computer. After trying several suggestion from various support sites, including Intel, I finally cleared CMOS, removing the battery and then reset jumpers. Now I can enter Setup, but of course can't use the keyboard to change the settings in BIOS. I want to load CD-ROM first, but can't access via keyboard to change. I suspect the motherboard is going out, but still have hope. This couple is elderly and fixed income so I'm trying to milk it for all I can. I can use his HD on my system just fine.

Debian Configuration :: Preventing Multiple Instances Of User?

Sep 6, 2010

Currently, a user is able to log into multiple terminals simultaneously, creating a copy of their roaming profile on each, and potentially causing problems if the instances are logged out in the wrong order. Is there any way to prevent this, so that if a user has logged in on a machine and not logged out (and perhaps some timeout has not yet expired) then their login attempts on another machine will be rejected.

OpenSUSE Install :: User Locked Out After Multiple Passwords?

Dec 5, 2009

I am having a problem with some users who get locked out after more than 3 failed attempts at login. This is exactly what I want to see - they will eventually remember those stronger passwords (maybe?) - but how do I re-enable their access? I haven't tried this on a live box but I can easily recreate the situation via vnc to the server in question and I assume the result would be the same. I like the policy that leads to this but I do need to let them back in - eventually. Where is the blacklist kept and how do I edit/reset it?

Software :: Monitoring User Account Used By Multiple Users?

Feb 3, 2011

I am in the process of setting up a user account for an SFTP server that will possibly be used by multiple users. I am aware of the security risk involved, but it is a necessary evil.

I am trying to come up with an effective means of monitoring the user account. So far I have a script that runs the finger command, and emails me once an hour. Is there something else that I can do to keep a close eye on the account?
