Passing Password To Encfs

Hello.
How can I write an Script that enter my password for "sudo" command automatically?
for example, I want to run a command that need root permission and when I write it in a bash script, it ask me "sudo" password for user but how can I automate it?
Can it possible for other program like logging via SSH too?

Thank you.

Hi everybody,

I used to be a Linux developer, but I have not used Linux or anything UNIX-like for a long time (more than 10 years). I had it installed by someone else and assumed that the root password is not set. Turned out - it has been. I can logged in as "owner" because I have guessed the password ("password") but no such luck with root. Can anything (other than reinstallation) be done? Is there some default password that root gets at installation that someone at this forum knows? Any other suggestions?

Thank you in advance.

Hello Friends,

I want to pass string variable with its value taken by user as command parameter in shell script, example below:-

echo "Enter New Password:="
read password


perl -pi -e
's/PASSWORD=.*?,/$password,/' abc.txt

Please let me know...
Thanks In advanced.

I first did the "try it", running it from the CD. I had the option to install from there and did. I cannot download any thing. My user name is John and there are 5 dots in the password space? My version is: ubuntu 14.04 lts. I was not able to change the root to read-write so I could change the password. Nothing worked unbuntu does connect to my wifi.
I'm a real newbie but what I 've tried in ubuntu has impressed me.
Help please

I have a shell script that calls an expect script I wrote to ssh login to another host and get user input regarding that host's network configuration. I pass four arguments to the expect script: the remote host ip address, the username, the password, and the list of commands to run. My expect script is below:

#!/usr/bin/expect
# Usage: expectssh <host> <ssh user> <ssh password> <script>

set timeout 60
set prompt "(%|#|\\$) $"
set commands [lindex $argv 3];

spawn ssh [lindex $argv 1]@[lindex $argv 0]

expect {
"*assword:" {
send -- "[lindex $argv 2]\r"
expect -re "$prompt"
send -- "$commands\r"
}

"you sure you want to continue connecting" {
send -- "yes\r"
expect "*assword:"
send -- "[lindex $argv 2]\r"
expect -re "$prompt"
send -- "$commands\r"
}

timeout {
exit }

expect -re $prompt
send -- "exit\r"
}

The script runs well, except that if I send a command such as 'read' that requires user input, the script does not continue or exit after the user presses enter. It just hangs.

The commands I pass to the expect script and it's call are as follows:
SCRIPT='hostname > response.txt;netstat -rn;read net_card?"What is the network interface card number? " >> response.txt; read net_mask?"What is the subnet mask? " >> response.txt'

/usr/bin/expect ./expectssh.exp $hostip $usr $pswd "$SCRIPT"

Any suggestions on how I can pass a command to my expect script that requires user input without it hanging?

On a side note because I know it will come up - I am not allowed to do key-based automatic SSH login. I have to prompt for a username and password, which is done from my main shell script.

Thanks for any suggestions and help you can provide!

I'm sorry to ask such a simple question but every time I think I figure something out or think I'm going somewhere get stopped dead in my tracks. My friend installed linux on my computer and then moved away immediately so I have no one to help me!

I downloaded the webcam program Cheese. I found through some tutorials that I have to copy the folder to the /opt/ folder and the only way to do that is through the terminal. I found this tutorial and still can't manage to copy the folder. These are the problems I run into:

1. I don't know where to open the terminal. I've tried opening it from the extracted Cheese folder in my downloads folder and from the /opt/ folder itself. It opens up but:
2. when I type the command sudo cp -r cheese /opt/ it will ask for modernnewspeak's password. When I try to type this in nothing happens, even though it JUST let me type in the command. I pressed "enter" thinking maybe it was hiding my password and I get the message "cannot stat 'cheese'. No such file or directory"

please tell me what I'm doing wrong! I tried to follow that tutorial and look through the FAQ here but I cannot figure this out. Thank you in advance!

I want to get the time when program starts and finishes. But it always show the same time. Here is my shell script. But it always show that `START TIME` is same as `END TIME`.
Code:

host_list=("c15-0330-01.ad.mtu.edu" "c15-0330-02.ad.mtu.edu" "c15-0330-03.ad.mtu.edu" "c15-0330-04.ad.mtu.edu")
program=("L_1" "L_4" "L_3" "L_4")
subject="The job is finished"
START=$(date +"r")
address="/home/campus27/zwang10/Desktop/AWRR/program/power/vmodel_1/nprot/K_10"
ssh -f "${host_list[0]}" "cd '$address' && nohup Rscript '${program[0]}.R' > '${program[0]}_sh.txt';echo 'The job\n $address\n${program[0]} is finished\nSTART TIME = $START\n' END TIME =`date +"%r"` | mutt zwang10@mtu.edu -s '${host_list[0]} - Job ${program[0]}.R finished' -a '$address/${program[0]}_sh.txt';"

In Linux Mint, I have right clicked on a folder and selected
"Sharing Options" -> checked the boxes to "Allow others to create and delete files in this folder" and "Guest Access..."

When I access the shared folder on Windows 7 it asks for a password. If I type a password in, it works.

I would like to configure it to not ask for a password, but just open the share.

Hi - I have the most aggravating problem. On my RHEL 5.2 w/s using gnome (or KDE), if you select "lock screen" from the pulldown and then try to unlock the screen with your password you logged in successfully with in the first place, it comes back shaking it's head INCORRECT PASSWORD. I did some digging and the /var/log/secure file is spitting out:

gnome-screensaver-dialog: pam_unix(gnome-screensaver:auth): authentication failure; logname= uid=500 euid=500 tty=0.0 ruser= rhost= user=username

Then below that also:

gnome-screensaver-dialog: pam_unix(gnome-screensaver:auth): auth could not identify password for [username]

I find this is happening on a few of my other RHEL systems too: RHEL 5.5, 6.0, and 6.5.

Help!

I have an expect script to SSH to a remote host and obtain some user inputs and information about the server/network configuration. The responses are saved in a text file that I then need to copy to my local host so that I can read the lines into variables for use in the parent shell script.

Is there a way to do this without needing to enter the username and password for the local host to use function scp? I have tried the following in my expect script to no avail:
Code:

spawn scp $usr@$host:$flnm .
expect {
	-re "(.*)assword:" { 
		send -s "$pswd\r"
	}
}

I have also tried to directly scp the file and enter the username and password to try to debug the issue, and that doesn't work either:
Code:

spawn scp file.txt user@host:file.txt
expect {
	-re "(.*)assword:" {
		send -s "password\r"
	}
	"you sure you want to continue connecting" {
		send -s "yes\r"
		exp_continue
	}
}

In both scenarios I have used exp_internal 1, and there are no errors. But I do not end up with the file on my local host.

Following the copy, I would like to delete the file from the remote host. Any suggestions on how to accomplish this?
