User add already exist

newbie14 · 02-07-2012, 08:17 AM

Dear All,
I am trying to chroot a user to just a folder and trying to follow the steps here http://www.thisisnotsupported.com/sf...il-on-centos6/ .The problem I am stuck here useradd -d /usr/local/test1 -s /bin/false -G sftponly user1 it gives me useradd: user 'user1' already exits. The problem I have add user1 before this steps. So how to go about it.

If it is just a test user which you created then delete the user and recreate changing the default home directory and shell

and if the user is useful then

Code:

#usermod -d (path to new dir) -s (path to new shell) username

usermod may be what your looking for to modify an already existing user,

This will give you the error because you haven't given the shell.

You can do like this if you want to give /bin/bash shell.

Quote:

# usermod -d /usr/local/test1 -s /bin/bash test1

For more information about usermod:

Quote:

# man usermod

And also check these pages for useradd and usermod:

Code:

#usermod -d (path to dir) -s (path to shell) -G (group name) username

in your case

Code:

#usermod -d /usr/local/test1 -s /bin/false -G sftponly user1

Dear All,
Thank you all that works and even the securing works the user can just sftp and see only one folder. Will there be any loophole for this sort of settings where they can access the other files via other routes?

If you have used chroot for any user then he/she will not be allowed to move out of his/her box.

and I believe you got your answer so Please mark the thread as "solved"

It seems there is some problem as even i don't see any "solved" option in my thread. I will request the moderator to look into this.

Dear Deepak,
Yes I cant see the word solved any where either. Thank you.
