I don't really know how you will fix this if this in Xubuntu 8.10.

If the release you are using is really Xubuntu 8.10, you should upgrade
to a supported release. Xubuntu 8.10 has not had any updates since
about April of 2010, so it is highly unlikely any kind of update or
anything caused this to vanish. It is strongly suggested to upgrade
this to at least 10.04, which is an LTS release, supported for three
years from its release. That makes Xubuntu 10.04 good until October of
2013, if you don't like upgrading.

Hello Charlie,



Thank you for your swift response. I apologize for the mistake:

I once started with 8.10 but now I work with Ubuntu 10.4.



Kind regards,



Daniel Hoogland

Hi there,

I did not alter anything of the system.

What do I have to do to get the connection to the Internet back again?

Default The Network Manager applet has vanished from the top panel in Ubuntu 8.10

Hello Mike,



Thank you for your help. After I gave in the command I got the
following reply:



An instance of nm-applet is already running.

** (nm-applet:1840): WARNING **: <WARN> constructor():

Couldn't initialize the D-bus manager.



It seems that the problem has to do with the D-bus manager (???).

Any idea how to proceed from here?



Thanks again, regards,



Daniel

Dear Mike,

From the above output, it seems that both your ethernet ports are down. Which one do you use to connect to the Internet. Try the following commands in a terminal. Atleast one might work.

sudo /etc/init.d/networking restart

ifup eth0
ifup eth1

Hello Alok,



After the command 'sudo /etc/init.d/networking restart' and
after supplying the password, Ubuntu replied:

Then I typed 'ifup eth0', and the system answered:



ifup: failed to open statefile /var/run/network/ifstate:

The same with 'ifup eth1':

How to proceed from here?

please add sudo in front of the command.

sudo ifup eth0
sudo ifup eth1

Then use the "ipconfig" or " ip addr show" to check whether your ethernet is up.

Default The Network Manager applet has vanished from the top panel in Ubuntu 8.10

Hello Mike,

The icon of Sound Preferences (a picture of a loudspeaker) is the only
icon that has been present all the time.

Nevertheless I followed your advice: I added the Notification Area which
added the Network Connection icon (a picture of a connected male-female
plug between a wired line) and the Rhythmbox icon (a picture of a
speaker box).
Then I opened Epiphany and received emails again. Browsing is also
possible.

Thus, adding the Notification Area proved to be the solution!.

Mike, thank you very much for your help! I am very glad that I can use
Ubuntu again.

Kind regards, Daniel

Default The Network Manager applet has vanished from the top panel in Ubuntu 8.10

Hello Alok,

I followed your advice. The system responded:

Ignoring unknown interface eth0=eth0.

then I typed: sudo ifup eth1

the answer was:

ifup: interface eth1 already configured


Another Linux user thought that the Notification Area icon had vanished
from the top panel line, and suggested to bring it back again via Add to
Panel, Notification Area, Add.
And this turned out to be the solution to the problem. So, I am back in
business again!. I am very glad that I can use Ubuntu again.

Thank you very much for your help,

kind regards,

Daniel
