# &kde; applications

&kppp;

Many &kde; users report problems using &kppp;. But before you complain about &kppp;, make sure you have already checked the following:

- Can you dialup to your ISP without using &kppp;? If you cannot, then perhaps &kppp; is not the culprit after all.

- Have you gone through the &kppp; documentation at least three times and followed its instructions and trouble-shooting suggestions?

The &kppp; documentation can be accessed through the &kde; Help Center. Last, but not least, the &kppp; homepage is at http://ktown.kde.org/~kppp/.

Now, if you still encounter problems, here's what might help you solve them:

How do I change the &MTU; setting in &kppp;?

  Open up the &kppp; dialog box and select Setup. Choose an existing account and click Edit, or New to create a new dialup account. Select the Dial tab and click Arguments. Type what you want to change in the Argument textbox (⪚ `mtu 296`) and click Add. When you are satisfied, click Close.

  To check whether the options took, do one of the following:

  - In a terminal window, run ``/sbin/ifconfig` ppp0` and look at the reported &MTU; in the output. It should match your request.

  - Add `debug` and `kdebug` (each on a separate line) to your `/etc/ppp/options` file and restart your &PPP; session. You will find debugging messages in `/var/log/messages`, including &MRU; and &MTU; settings.

  If you want, the &MRU; and &MTU; settings can be added to the `options` file, one complete setting per line, no quotes or dashes.

&kppp; connects at a slower speed than normal.

  The following might do the trick:

  - Try executing `setserial spd_hi`.

  - The default &MTU; value is 1500, which maybe too large for a dialup connection. Try changing it to a smaller value like `296` or `576`.

  - Check in your `$`HOME`/.kde/share/config` for the `kppprc`. Ensure the correct modem speed is actually defined there.

How do I page-up or page-down?

  Use Shift Page Up and Shift Pg Dn.

How do I perform a simple copy from &konsole; to anything else?

  When I do a `ls`, first I select with the mouse the desired text, press &Ctrl;C, then I make the target application active, point the mouse to the relevant part and press &Ctrl;V. Alternatively, highlight the text by dragging with the &LMB; down and paste by clicking with the &MMB; (or both buttons if you are using a 2 button mouse with 3 button emulation).

Why can't &konsole; find the 9x15 and the 2 console bitmap fonts installed with &kde;?

  FontConfig must find the three fonts installed in: `$`KDEDIR`/share/fonts`. If the &kde; install does not install these fonts in a directory that already exists (⪚ `/usr/share/fonts`) then you must add this directory to the configuration file `/etc/fonts/local.conf`. This should be the first line after <fontconfig>. For example:

      <fontconfig>
      <dir>/usr/kde3/share/fonts</dir>
      </fontconfig>

  After adding the directory, run (as root): ``fc-cache` -v` and check that it found the directory.
