How to remove the 2 old Linux kernel modules from kernels 3.0.0-19 und 3.2.0-26?

~$ man dkms

"'dkms remove [module/module-version]' removes a module/version combination from a tree.'

What is a "[module/module-version]", please?

Please notice:

I do not want to remove old Linux kernel modules tp_smapi from a tree but I'd like to remove old Linux kernel modules from my Ubuntu 12.04.1 computer.

How to restore on another Ubuntu computer a MySQL database backup made by rsnapshot on an external USB hard disk? This seems to be difficult because the UID and GID of mysql differ on both computers.

I could work around by determining UID and GID of mysql on the target computer, copying the database in /var/log/mysql/ and running the command ~$ chown -R newuser:newgroup newdir.

Is there a more straightforward solution?

Midnight Commander 3.4.8.1 > File Find. What text do I have to put in the »Content:« text field and in the other fields? I tried several settings in the other fields but mc always returned no result. (This is not explained in 'man mc'.) My hope is to perform some grep-like action using mc. http://svn.dd-wrt.com:8000/browser//src/router/mc2/src/filemanager/find.c did not enlighten me.

I just experienced an unusual crash: I tried to click on a name entry in the contact list of Empathy. A crash happened. Usually I am asked then if I'd like to report the error to Launchpad, and Launchpad opens. This time the error message was:

"Excuse me. Ubuntu 12.04 noticed an internal error. If you notice further problems try to restart your computer. Send an error report to Launchpad to help removing this problem?"

This time Launchpad did not open automatically. A new window opened and I could read the relevant error report. Later I found the error report in the file /var/crash/_usr_lib_empathy_empathy-chat.1000.crash. Why went the course of action this time differently from other crashes? Why is the file /var/crash/_usr_lib_empathy_empathy-chat.1000.upload empty?

When dist-upgrading Ubuntu 11.10 to 12.04 UpdateManager asked to enter a "new" user password for MySQL. I denied 3 times. This asking was put misleadingly. I better should have entered a user password for me for the »MyQSL« privilege system, as I know now.

Now my database »mysql« > table »user« does not shows a password entry for me. I can do most administrative tasks on my MySQL database though. I feel that this is a security gap. I'd like closing it.

I entered a password. But now I cannot access my MySQL server through my LibreOffice Base frontend any more: "Access denied." How to rconcile both requirements?

[Ubuntu 12.04] When exporting large (100 MB) data from a table in LibreOffice 3.5.2.2 Base embedded HSQLDB to a Calc spreadsheet using the procedure outlined in LibreOffice Help, LibreOffice Base and Calc freeze after ~14 min. I can move the cursor though. The same process with a small table (~10 kB) works all right.

How to obtain an error message? Is it really necessary to install the DEB program package libreoffice-dbg and using gdb or strace?

Why does '~$ nc -z T43 1-1024' not produce any output although '~$ ping T43' is successful?

'~$ nc -z -v T43 1-1024' prints 'Connection to T43 22 port [tcp/ssh] succeeded!' and 'nc: connect to T43 port 1000 (tcp) failed: Connection refused.'

'man nc': "PORT SCANNING: It may be useful to know which ports are open and running services on a target machine. The -z flag can be used to tell nc to report open ports, rather than initiate a connection. For example: '$ nc -z host.example.com 20-30'.
