Hide Password Ftp With The Same User

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?

In our environment i have to ssh to each an every servers
ssh <hostname> then which prompts for password for every login
i have to create a user name on 30 severs manually it takes much time so need a script to do this task i have googled and found some for loop scripts but it did not fullfill the requirement.
First i have to check whether the users exists and not and later add the user or reset the password for user using script

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!

Wow, I got my new Linux pc yesterday and it's very very fast. It's faster than my new MacBook.
So I go to the user account which also says administrator so I'm presuming that's the root owner?????? and I typed in my name and changed the password. The guy who sold it to me named the password user and the computer user. Yet when I go to the terminal my username and computer is still called user@user
How do I change the root password and computer name?

So I created this big script and want to ask for username and set a variable, however if the username exist in the username variable then continue with script otherwise ask the user to enter his name.

Flow:
-- start script "Enter User Name"
-- ask user to input username
-- if username is blank or different value then put that username in $USERNAME variable
-- then continue with the rest of the script

-- next time this user runs the script it will have his name loaded so he just presses enter to continue with the script.

-- If it is NOT the same user then, new user can erase existing input and enter a new name.

Hope it makes sense...

Thanks in advance for the help.

Hello Everyone,

I have a question about how to give sudo privileges to a user that log in via public key without password.

I created a normal user and I added this user to the "visudo" folder with ALL privileges.

when the user is logged in the system via public key and the user wants to become a root, a password is requested but i don't want to type the password.

Also to add the public key to the root it is not possible because i track the user log in in the system and if they log via root i cannot do that.

Thank you in advance.

I have two VM's on a Redhat 7 Base machine and installed Redhat 6 on both machnies. Trying to use FTP. I can ping both each other.
VSFTPD is installed,
firewall is enabled.
vsftpd.conf is also updated for anonymous user login.
I could login using anonymous user.
while uploading file
I am getting a message as ftp: connect: no route to host

user="john bob randy susan"
I extracted local user list as: cat /etc/passwd | cut -d ":" -f1

Now I need to write a script to find the difference in user between these two (users defined as above and local user). I tried many ways its not working. Any help

#!/bin/bash
users="john bob randy susan"
luser=`/bin/cat /etc/passwd | cut -d ":" -f1`
......
....


Thank you
