Git /usr/local/lib/liblber & /usr/local/lib/libldap_r no version information available error

MySQL Admin via SSH Tunnel
Lets create a ssh tunnel into our remote server so that we can connect MySQL Administrator. This will trick MySQL Administrator into thinking that it has a local connection to the remote machine when it doesn’t. This is great for getting around having only local MySQL access rights while trying to login from a remote machine.
Now boot up MySQL Administrator and connect to localhost or 127.0.0.1 port 3305. Bam, your into your remote mysql server.
You may notice some werid things like “Server not running”, ignore it. Basically it means that it has connected to the MySQL server but can’t find the program running locally. Also the MySQL Administrator interface will hang a bit when fetching data. Silly one threaded programmers. Always disconnect your UI from the data via threads!

Open remote application window over ssh – X11
You left the office but forgot to leave an application running. An application that requires it’s GUI, you try to open it via ssh but “Error: Can’t open display” prevents you.
Simple fix here, you will kick yourself.
