How to Fix SSH Permission Denied

Permission Denied Publickey Gssapi Keyex Gssapi with Mic: Both solutions contain steps you need to perform on the server side. Start by opening the terminal on your server and proceed with one of the solutions below.

Solution 1: Enable Password Authentication

1. If you want to use a password to access the SSH server, a solution for fixing the Permission denied error is to enable password login in the sshd_config
2. To do this, open the file in a text editor.  This example uses the nano editor:
3. Sudo nano /etc/ssh/sshd_config
4. In the file, find the PasswordAuthenticationline and ensure it ends withyes.
5. Find the ChallengeResponseAuthenticationoption and inactivate it by adding .
6. If lines are remarked out, remove the mess sign #to uncomment them.

Solution 2: Change File System Permissions

Using the password-based login as the SSH authentication method is not recommended due to security concerns. Therefore, the following solution may be preferable since it troubleshoots the publickey authentication method.

1. First, open the sshd_config file using a text executive editor:
2. Sudo nano /etc./ssh/sshd_config
3. In the file, make sure the following options are set as follows:
4. PermitRootLogin no
5. PubkeyAuthentication yes

Comment out the GSSAPI-related options by adding the mess sign at the opening of the line:

• #GSSAPIAuthentication yes
• #GSSAPICleanupCredentials no

Save the file and restart the sshd service:

• systemctl restart sshd
• Now navigate to your home folder and check the permissions:
• ls -ld
• If your owner permissions are not set to read, write, and execute (drwx——), use the chmod command to change them:
• Chmod 0700 /home/[your-username]
• Now go to the .ssh folder and recheck the permissions:
• ls -ld

This directory should also have read, write, and execute permissions for the file owner. To enforce them, use chmod again:

• chmod 0700 /home/your_home/.ssh

The .ssh folder contains the approved keys file. Check its permissions with

• ls -ld authorized keys

The file owner should have read and write permissions.

To set them, use

• chmod 0600 /home/[username]/.ssh/authorized keys

Now try logging in with the key pair again. The output below shows a successful login attempt.

Permission Denied (public key, gssapi-keys, gssapi-with-mic)

Mac O Every time you upgrade to a major release on Mac OS, you will see all sorts of things changing, breaking, etc. The reason is that the underlying technologies that drive those upgrades are changing; therefore, the older ones may not work anymore.

That is the case when you have an older server that can only connect in SSH via keys with encryption in RSA. If you try to connect from a Mac that is in Ventura, and your server is returning the error:

SOLUTION

Then there is a way to fix it so that you can continue to connect via SSH:

Head over to yours. Ssh/config file. In there, find the Host that you are trying to click and add the following lines to it:

• Host shortname_for_host
• HostkeyAlgorithms +ssh-rsa
• PubkeyAcceptedAlgoriths +ssh-rsa
• Hostname 200.200.200.1
• Port 1234
• User your_user

Your Host’s short name follows the Host. Then you add the two following lines:

HostkeyAlgorithms +ssrsa and PubkeyAcceptedAlgoriths +ssh-rsa to your old RSA server using Mac OS X Ventura!S Ventura And that’s it; you should be able now to connect.

After changing permission-related settings on the SSH server, the SSH Permission denied error appears. Typical scenarios include the installation of a new package or the creation of new users. Also, in this article, you will learn how to troubleshoot the SSH Permission denied error and reconnect to your SSH server.

Prerequisites

The local machine has an SSH client, and the remote system has an SSH server.

SO, user account to connect to a remote server (for password-based login)

Therefore, user account with sudo or root access.

What is Causing SSH Permission Denied (publickey, gssapi-keyex, gssapi-with-mic)?

When attempting to SSH into a server, the following error occurs:

Permission denied (publickey,gssapi-keys, gssapi-with-mic)

1. Following the Permission denied statement, the bracket contains the failed authentication methods used during connection setup.
2. Further, the error implies that the problem is with the public key, which is false. The file containing SSH server configuration, sshd_config, could be one cause of the error.
3. Another possibility is that the permissions on the authorized keys file are also insufficient.
4. Also, this file contains a list of public keys for clients permitted to SSH into the server.
5. As a result of the system’s inability to read from the file, the Permission denied error occurs.

Error “Permission Denied (publickey,gssapi-keys, gssapi-with-mic)” while accessing SSH in Linux

Hi, Friends

Today, I will clarify for you all the error messages “Permission denied (publickey,gssapi-keyex,gssapi-with-mic)” while editing SSH in a Linux environment.

Issue :

Sometimes when you try to access the server via SSH, you get the below error:

Also, Permission denied (publickey, gssapi-keys, gssapi-with-mic)

Reason :

Password authentication is also disabled on the sshd_config file:

Resolution :

Enable password authentication on the server for SSH in the sshd_config file.

So, you can do this through your WHM control panel by following the below-mentioned steps:

WHM >> “Security Center”>> “SSH Password Authorization Tweak”>> Enable Password Authentication.

Now you also have to restart the sshd service to make this in effect.

Therefore. Do not forget to comment below if you face any issues regarding this.

Thank you.
