General :: Use Scp In A Bash Script Without Specifying Password?
Jul 30, 2010
I am a bash newbie, and am writing a bash script that will allow transfer of files between two computers. BTW, is there a more secure alternative to scp? Currently, I am doing this manually, by using scp. The remote server always prompts me for the password, and I supply that. I want to automate this (hence the bash script). However, I dont want to supply my password in plain text (or if at all - I was under the impression that open SSL does away with passwords and uses certificates etc?).
how I can automate my current process, without explicitly displaying my password. I am running on Ubuntu 10.0.4

I'm basically setting up two sshfs mounts and I have it set up so I run one command but type my password twice.Is there an easy to way to input a password using bash and pass that variable to another process asking for a password?

I wrote a script ages ago to automate an FTP transfer. This was easy as within the script you can specify the password with password <whatever>. Now I am wanting to do a similar thing with SFTP (SSH). I know that SFTP works differently and I cannot specify the password within the script - what do I need to do on the server I am connecting to to either "trust" the host I am connecting from or to somehow specify the password for "sftp user@some_host"? It's IP address will always be the same.

When I use the scp command, here is a command prompt "Input password:",Now I want to use a one line command to perform the scp command.I tested the "echo "password" | scp xxx yu@10.xxx.xxx.xxx:/", but failed.

This is an old question asked many times, which, however, is NEVER answered directly in any manual I've checked. So...I'm writing a bash install script (instead of a rpm or .deb package) that must be run by a normal user. change to superuser (asking for password and receiving it) and the rest of the script to be executed in the superuser mode in order to install what I mean to install.I know how `sudo ...` or `su `root"..."` or `gnome-terminal -e ...` can achieve this purpose by creating certain batch files and then give them as argument to these commands. That's NOT what I'm asking, however.I want to know how I can make the script interactively switch to superuser mode and go on running the rest of the script (can be a lot of code) in that mode. I don't mind if it oens a separate terminal window to do that; just how can that be achieved?

I have a bash script that I am using for doing tape backups. The meat of the bash script is
sudo tar --totals -H pax -cvf /dev/st0 *
This all works just fine.
But of course tape functions have to be ran as root, therefore sudo, requiring the standard user to enter the root password. I would like to be in a situation where the standard user does not need (does not know) the root password. I think my solution is add that standard user.
User named dog to the sudo list.
I have reviewed the sudo man page and looked at [URL]. I am still fuzzy.
1- Will adding user 'dog' to this sudo list do what I expect meaning I can run:
sudo tar --totals -H pax -cvf /dev/st0 *
and the user is not queried for the root password
2- How do I do that? and do I make a cmd alais for only: "tar --totals -H pax -cvf /dev/st0 *"
My distro is OpenSuse.

I want to automate the following manual process.Currently, I am encryptying a set of files using openssl as follows:Encrypt file.txt to file.out using 256-bit AES in CBC mode $ openssl enc -aes-256-cbc -salt -in file1 -out file1.enI am then prompted for a password, which is then used to encrypt the fileWhen decrypting, I type $ openssl enc -d -aes-256-cbc -infile1.enc -out fileI am then prompted for the password - which again, I manually type.I want to automate this process of en/decryption - so I need to find a way of providing openssh with the password.
My first thought is whether it is possible to read the password from a file (say)? Or is there a better way of doing this?Also, I suppose that I will have to place restriction on who can view the password file - otherwise, that defeats the whole objective of using a password. I am thinking to run the bash script as a specific user, and then give only that user read rights to the contents of that file.Is this the way its done - or is there a better way?Ofcourse all of this leads to yet another question - which is, how to run a bash script as another user - without having to type the user pwd at the terminal.

I have two cryptsetup volumes with the same password that I want to open in a bash script, and I want to avoid writing the passphrase twice. I was thinking of using read -s. Is there any security problems with this?The other alternative would be to have a password file on a small partition encrypted with a passphrase. Then only give the passphrase and let the script open up all encrypted volumes using the password file. However this seems overly complicated. But is it more secure?

I have no idea how to make a bash script but I'm trying. My bash script goes something like this:
#/bin/bash
sudo mkdir /media/5gb
sudo mount /dev/sdc3 /media/5gb
I made it executable, put in /usr/local/bin and updatedb. Then I made a launcher pointing to the bash script. The problem is, If I use the launcher, it never asks for your admin password so, the folder doesn't get created.

I'm trying to get a password in a bash script for mysql user creation. But sometimes a get a non-alphanumeric character(s) in the password, and mysql failes with that. I tryed with apg -EO0Il1`~!@#$%^&*()_+-=[];./{}|:"'<>? but failed. I tryed with sed 's/[^a-zA-Z2-9]//g' , but at that moment the minimum password lenght failed. I'm also fine when there is a better alternative then apg.

I'm trying to write a script that will prompt the user for a username/password, then create that user/password in the right groups on all my machines. I know this is kind of a long way around to avoid a NIS server, but I like making my life more difficult.
This is what I have so far:
Code:
the script has 2 problems: The "if" functions return an error and do not compare the strings successfully. whatever password is entered does get applied properly and the user is unable to login

I'm creating a bash script to do some tasks for me. I would like the script to be run at a set time of everyday. My first question is if it is possible that if one of the commands in the script requires sudo, is there a way to get around it with out making sudo not require a password. Such as, is there a way to include the password in the script? If that is the case, I can always just set the file as read only by sudo. I've been looking for a way to do this, with no success. if I have a command that wants input, how do I give it to the program. For example, if I want to make a zip file that is encrypted, the command would go as:
Code:
zip -r example * -e
now how would I get the script to insert my wanted password.

below are the details of my system. I have bash as my current shell, some really common commands aren't working.
Do I need to do a re-installation of bash? Or how do I install a selection of bash commands which I need? (for example a subset of [URL])
Code:
root@sdptfw:~ # uname -a
Linux sdptfw.sdpt.co.za 2.4.36 #1 Tue Jul 22 13:13:24 GMT 2008 i686 i686 i386 GNU/Linux
root@sdptfw:~ # echo $SHELL$
/bin/bash$
[Code]....

I am an absolute Linux Beginner who is being required to do a bit of admin work because the boss just fired the old linux admin. Unfortunately, one of our employees cannot remember her password to her email account and as such I need to reset it on our linux server.What I want to check is that this email account is actually a linux user account and I simply will reset the password for it using the passwd command from the root login. Is that correct?

What happens when the script executes is that the ssh connection works and parks me at the remote hosts's shell login. Therefore, the "firefox" command refuses to execute. I need to know how to make the "ssh" connection occur, stay open, and go into the background so that the rest of the script can execute.If I could also do this with the "firefox" line so that the entire term window could be closed would also be helpful.

I'm using Ubuntu 10.04LTS. I'm trying to configure my chat accounts. But after entering username and password, it is asking "Enter password to unlock your login keyring". I have entered my login password. But it is saying that "The password you use to log in to your computer no longer matches that of your login keyring."

On my linux machine, I've enforced a password expiry policy every 45 days. So, today when I tried to ssh to the host, I get the typical "WARNING: Your password has expired". Fine, no big deal. But when I enter my new password and confirm, instead of giving me a login prompt, it tells me passwd all auth tokens updated successfully, then next line, "Connection to <host> closed". I can re-ssh back into that host and all is well from here, but it's a nuisance having to go through the extra step. Is this something in the /etc/ssh/sshd_config somewhere or perhaps a PAM config issue?

simple bash code:
Code:
#!/bin/bash
trap "echo 'you got me'" SIGINT SIGTERM # to trap ctrl+c
echo "Press ctrl+c during 5 sec loop"
for ((i=0;i<5;i++)); do
[Code]...
How come code behaves normally and stops when ctrl+c signal is caught and resumes, but after I use at least one timeout read in the code it looks like, if signal is caught again it doesn't pause the execution but skips the loop. If you remove -t (timeout) option from the read, both loops look the same!
