Troubleshooting MySQL Workbench SSH Connections on Ubuntu: A Comprehensive Guide

MySQL Workbench is a powerful tool for managing MySQL databases, but sometimes connecting via SSH can be tricky, especially on the latest Ubuntu version. In this article, we’ll explore common issues and provide solutions to ensure smooth SSH connections.

SSH Key Configuration:

  • Make you sure that you have copied your SSH keys into the right places. If you’re using a snap packet of MySQL Workbench, make sure you’ve given yourself the right to have the SSH keys in the snap permissions dialog. 
  • When you connect using ssh, it’s possible that a pop up from the command prompt saying “SSH tunnel could not be opened, please check authenticity of host” appears to your screen. Confirm the connection (e. g. Finally you have to click “OK”, and don’t worry about crashing as there is a chance it can happen. )
  • If MySQL Workbench fails to add the SSH fingerprint, it will result in a regular prompt. Simply confirm that the SSH key is not being accosted by the known_hosts file. 

Known Hosts File:

  • The known_hosts file is absent or unwritable as the reported cached error shows MySQL Workbench attempting to both read and write to it. Nevertheless, it faces the challenge of permission. 
  • In order to do this, create an empty known_hosts file in the right folder (runtime location if applicable). g. , /home/user/snap/mysql-workbench-community/12/. ssh/known_hosts). 
  • Under “Edit” menu, you can set the known hosts filename providing in “Preferences > SSH > Known hosts filename”. 

Upgrade Paramiko Package:

  • In case you are using the Python-based MySQL Workbench, it is very important to upgrade the Paramiko package. Paramiko is Python's library that realizes SSH connections. 
  • The old or incompatible Parrtik ping version might be the root cause of the issues sometimes. And upgrading to a newer version might be the solution to the problem. 

Check Server Configuration:

  • Check `your` MySQL server configuration to ensure `that` it permits SSH connections. Ensure that Spesialpaalman SSH is running and properly configured. 
  • Copy SSH key (converted to OpenSSH format) and paste into the authorized_keys file on the server. 
  • After a round of changes, simply restart the SSH (sshd) and MySQL services (MySQL might require some commands). 

Strace Output:

  • Well, what you have seen in the strace output is that there is a bit of a problem because MySQL Workbench is reading and writing into a known_hosts file and then immediately crashes. Find out about the permissions and ownership of that file. 
  • Ensure that the murderer of MySQL Workbench has the appropriate permissions to peruse and modify the mentioned file. 

Keep in mind that troubleshooting SSH is more complicated than MySQL Workbench or MySQL server and SSH configuration, which means you have to check both client-side components and server-side components as well. In case of any additional difficulties, you can still try asking for help on the relevant forums or community support channels. I hope your connection to MySQL Workbench blows you away.
