LibO won't connect to remote database using Java Connector


I’m using Libo base to manage my addresses and much more. But it seems I cannot connect to a remote database (mysql) using the java database driver.

On a localhost it will connect, however I have setup a database on a ubuntu server 12.04 LTS version somewhere on my LAN.

When I connect I get the following error:

SQL Status: 08S01

Communications link failure

The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

It looks like there is a problem on the server end but I have setup the firewall to let port 3306 thru, so the firewall shouldn’t be a problem.

This is my setup.


  • linux mint 13 LTS (maya)
  • Libo: version (Build ID: 360m1(Build:102))
  • JDBC-driver: 5.1.22 (from Oracle/mysql)


  • Ubuntu server 12.04.1 LTS
  • Phpmyadmin
  • Mysql server 5.5.24

I do connect by IP. For Libre office should it be like: :3306

My question is, why is it not connecting to the server?

Showing the URL string used to connect, maybe someone can verify it.

Thank you, i do connect via IP. So i fill out the fields like this: server: Port: 3306. I did try it be name also but no luck.

I’ve got just about the same problem…
I had to replace my server, re-installed on new hardware and now it doesn’t work anymore… I can connect from my workstation to the dbase with phpmyadmin, but not with LibreOffice… SQL Status: 08S01 Communications link failure.

Client side: Win7
Server side: Ubuntu 12.04.1

I think I have the same setup as before, but now it doesn’t work… I can’t figure out what’s wrong… Could it be the “mysql_secure_installation”? I think that is the only difference… Thanks…

Take a look to this thread, about “Debugging Communication Link Failure exceptions in Connector/J”.
