I verified that root password is correct, but no matter how many times I tried, I can't su in
Where's my su permission
-rwxr-xr-x 1 root wheel 24060 Mar 22 2007 /bin/su*
here's inside /etc/group
wheel:x:10:root,hen
im able to login to root via SU perfectly
One problem: All my old files and folders are owned by ROOT so that means my SU account named XXX cant edit/add/delete anything from my SFTP because of folder/file permission.
Is there anyway my SUDO(wheel) account can still edit these files own by ROOT?
I tried to disable direct root login but had to struggle to find step-by-step instructions and have written the steps one needs to follow to disable direct root login.
This is an additional security measure where we prevent direct root logins and instead create a user to login and then use a command ‘su –‘ to gain root privileges.
The only risk in this procedure is that you may prevent root login but forget to add the user to the wheel group - effectively locking yourself out of the system.
Follow the steps below and you will not face a problem.
STEP 1: Let us create a user and add it to the wheel group.
For e.g. we want to create a user neonix and give him root privileges.
SSH into your server as root and follow the below commands to create a user.
groupadd neonix
useradd neonix –gneonix
passwd neonix
enteryouruserpasswordhere
verifyyouruserpasswordhere
// Please note -g in the second line
// You can replace neonix with any username of your choice.
STEP 2: Add user to wheel group.
Use your browser to Login to your WHM panel and click on Manage Wheel Group Users.
You will see the user you just added (neonix). Select the user and click ‘Add to group’.
You will see that the user has been added –
Users Currently in the wheel group root,neonix
You have successfully added a user to the 'wheel' group who will be able to 'su -' to root.
LOGOUT OF SSH
Before we disable root login, let us check if the user can login and su – to gain root privileges.
SSH into your server as 'neonix'
Login as: neonix
Password : enteryouruserpasswordhere
su –
password: enter root password here
You have successfully logged in and have root privileges. Now let us disable root login.
STEP 3: Disable Direct Root Login
(The below steps are from webhostgear.com)
1. Copy and paste this line to edit the file for SSH logins
pico -w /etc/ssh/sshd_config
2. Find the line
Protocol 2, 1
3. Uncomment it (Remove #) and change it to look like
Protocol 2
4. Next, find the line
PermitRootLogin yes
5. Uncomment it (Remove #) and make it look like PermitRootLogin no
6. Save the file Ctrl+X then Y then enter
7. Now you can restart SSH
/etc/rc.d/init.d/sshd restart
Now, no one will be able to login to root with out first logging in as 'neonix' and 'su -' to root, and you will be forcing the use of a more secure protocol.
Just make sure you remember both passwords!
Currently I have a server that has direct root SSH access disabled (have to login as regular user then su to root), but I am currently working on setting up authentication via SSH keys, but I can't seem to get it working with direct root SSH access disabled? Is this normal, and if so is there anyway to work around it?
Basically I'd like to be able to authenticate both ways; both with SSH keys or by logging in as a regular user and su to root.
I have a website which has a FLV player serving .flv files which are hosted in the server. I notice that some users are directly downloading the files using the direct URL and they seem to be using download managers for that which is opening several Apache connections and open slows down Apache. I want to prevent this. I thought of preventing it using a .htaccess file but did not help. This is what I used:
<Files *>
order allow,deny
allow from 127.0.0.1
allow from localhost
deny from all
</Files>
I thought this would work but it doesn't as it is blocking the FLV player from playing the file. Can anyone tell me the right way to do it?
in order to secure my server against instrusion, i disabled ssh root login and created a user for myself. however in order to access the user i need to enable SSH Password authentication
I dont enable password authentication all the time and i keep it disabled unless i need to do something via ssh.
Now my question will be, is there a way to keep the user i created and keep the root login disabled and password authentication disabled but use ssh keys for the user i created?
I was informed that if i opt to login to ssh via the user i created, the only way to do that is to enable password authentication as it cannot work with ssh keys. is this true?
I really hope someone can help me how to use the user i created together with ssh keys so i dont have to enable password authentication when loggin to ssh
I use a login script on my hosting site. and i was wondering if there was any way or any program that would allow me to Block people from going mydomain.com then cpanel?
And forcing them to go to my site to use the cpanel login script on my website?
Im sure that if there was a way to disable Cpanel login it would aslo block the scipt on my site.
Is there a solution to my little perdicament here?
Any software or scripts that do what im looking for?
I was worry about which is more seucre to login to the server
disabling the direct login and using the public key (ssh-dss) with 2084 bit length ?
or use the direct login?
and if the public key is more secure , should we use passphrase when generating the key? or no?
I'm Running (just) Direct Admin On a Centos 4.3
Due to a typo at the comand line as Root, ive manages to change the owner ship of unknown mounts of files.
The command that was processed (Before it was complete)
chown -R reseller:reseller /
I managed to stop the process ctr+c
and these were the last files to see fly past.
The last one in the list is where it stopped at.
Code:

At the moment the server is still running and it seems only to be log in issues with Direct admin. All user / reseller / Admin accounts can no longer log in.

View 4 Replies View RelatedIs it possible to disable direct root login on Cpanel servers?
if yes, please how.
If not, what would be the best to do to secure 'root' account.
Meaning you can't use the user root to login to WHM.
Is that possible?
We have an internal server running Red Hat 8 or 9 that was taken offline at least 18 months ago. The guy who set up the box is long gone. Unfortunately with him went the root password. It wasn't a big deal until we realized there is some code we do want to get off of that box now that may be useful in a future project. In particular the database structure for one project. Is there any way to get access to this data or is it just lost?

During the installation of Plesk, at first it used the root password, and then had me create an "admin" user.
When I log in using either I don't see any difference in the UI or options. Is there a difference or a reason to use one over the other?
Or is it just to give someone access to admin Plesk without giving them full root password of the server itself?
I have read that although chained root ssl certificates can be more difficult to install they are actually more secure since the root certificate cannot be compromised, only the intermediary.
Is this true? It looks like both google and amazon both use chained SGC certs.

Browse to www.mydomain.com/webmail and get login box > login accepted and taken to Horde/Squirrelmail choice screen > choose Squirrelmail and get login box ... login not accepted! > Retry and choose Horde ... login not accepted!
The login is correct and the results are the same when logging in as root, or through /cPanel or /Webmail.
