vsftp Error -203: miscellaneous error occurred while trying to login to the host

Your ftp user needs to have a home directory. 


Try creating your user this way instead:

sudo useradd -d /home/ftpusername -m ftpusername

sudo passwd ftpusername


Ps. If you need to delete your existing user, use:

sudo userdel ftpusername

Mail in Ubuntu. Sendmail log file says 'User unknown'

I was getting the error'

I realized it was because my domain name was set in the local-host-names file.

To fix this I:

1. opened up the 'local-host-names' file
i.e.
sudo nano /etc/mail/local-host-names

2. Removed my domain name from the file.

3. Then restarted sendmail:

/etc/init.d/sendmail restart

It doesn't seem critical, but seems a bit annoying. To fix this, I added the following line at the bottom of "/etc/apache2/apache2.conf"


ServerName localhost


Then restarted apache.

Installing Java 1.4.1 on Ubuntu 9.10 (Karmic Koala)

Installing Java 1.4.1 on Ubuntu 9.10 (Karmic Koala) turned out to be nothing but a pain.

Firstly, Java 1.4.1 has now reached End of Life, so Sun doesn't support it any longer.

1. So, download Java 1.4.2_07 from the archive: http://java.sun.com/products/archive/j2se/1.4.1_07/


2. Then when you try to set the file to executable by 'chmod -x' and then run it, you're likely to get an error message like:

"tail: cannot open `+341' for reading: No such file or directory"

Then something about the download being corrupt.

This is because (according to here) the tail program in Linux has changed slightly since then and has a different syntax.

To get around this, I unzipped the .bin file using 7Zip on a Windows system; but I guess p7zip can be used on a Linux system too.

3. Then I placed the 'j2re1.4.1_07' folder into my /usr/lib/jvm/ folder and did the procedures 5 to 6 as in the previous post.

4. Then finally, manually added the plugin (so that it works in Firefox) to the list of plugins as given in the 'Java Applet Runtime Settings' -> 'View' in the GUI for the ControlPanel command.

Downgrading Java Version in Ubuntu and Firefox to 6 update 11

Fortunately Ubuntu allows for users to change the Java version used and also run multiple versions of Java. To do this:


1. Download JRE 6u11 from here:
http://java.sun.com/products/archive/j2se/6u11/index.html

2. Chmod +x it. i.e.:
sudo chmod +x jre-6u11-linux-i586.bin

3. Move it to the jvm folder
sudo mv jre-6u11-linux-i586.bin /usr/lib/jvm/

4. cd to that folder and run it

cd /usr/lib/jvm/
sudo ./jre-6u11-linux-i586.bin

5. Now add it to the alternatives:
sudo update-alternatives --install /usr/bin/java /usr/lib/jvm/jre1.6.0_11/bin/java 500

6. Then you can select to use that version of java by running:
sudo update-alternatives --config java

Now that's all well and good; but it will still be running the newer version in Firefox. So:

7. Run the java control panel, by typing:

ControlPanel

Then click on the tab 'Java' and the button 'view' under 'Java Applet Runtime Settings'

From there, you can disable any unwanted Java versions.

8. The plugin inside Firefox's setTest your Firefox java version here:

Unfortunately my Cisco PIX 501 Manager STILL does not work with this.
