Configuring and Running KPPP
|
||
|
|
============================
|
||
|
|
|
||
|
|
In order to use KPPP, you must first be a member of the "dip" group.
|
||
|
|
Membership in this group is a prerequisite for any and all use of ppp in
|
||
|
|
Debian. If you are not a member of this group, you will not be able to run
|
||
|
|
the ppp daemon (pppd) or make a dialup connection. Since KPPP's backend
|
||
|
|
runs SUID root, membership in the "dialout" group is not needed to access
|
||
|
|
device nodes.
|
||
|
|
|
||
|
|
KPPP also requires that the ppp daemon be run with the "noauth" option.
|
||
|
|
However, pppd's default setting, in /etc/ppp/options, is "auth", and for
|
||
|
|
security reasons it should remain so. To work around this problem, uncomment
|
||
|
|
"noauth" in /etc/ppp/peers/kppp-options. You should then be able to connect.
|
||
|
|
|
||
|
|
Note that if "noauth" is uncommented, a setting of "noauth" in
|
||
|
|
/etc/ppp/options will conflict with KPPP. Note also that uncommenting
|
||
|
|
"noauth" opens the possibility that other malicious members of the "dip"
|
||
|
|
group might potentially abuse the ppp daemon.
|
||
|
|
|
||
|
|
Finally, if you are uncertain as to which device node represents your modem,
|
||
|
|
you can try to find out by running "dmesg | grep tty". The output of this
|
||
|
|
command will sometimes provide the needed hint.
|
||
|
|
|
||
|
|
If the answer seems to be that your modem is on a node, such as ttyS28, that
|
||
|
|
KPPP does not accept as a configuration option, then you should create a
|
||
|
|
symlink from that node to /dev/modem (by running, as root,
|
||
|
|
"ln -s /dev/ttyS28 /dev/modem", where ttyS28 is replaced by whatever node your
|
||
|
|
modem is on). Then simply configure KPPP to use /dev/modem. Further modems
|
||
|
|
with non-standard device nodes can likewise be symlinked to /dev/modem[0-3].
|
||
|
|
|
||
|
|
If you use udev, then symlinks in /dev will not be preserved
|
||
|
|
across reboots. In this case, you should edit, as root, /etc/udev/links.conf,
|
||
|
|
adding a line that resembles "L modem /dev/ttyS28". You must then either
|
||
|
|
reboot, or run "/etc/init.d/udev restart", for the link to be created.
|
||
|
|
|
||
|
|
If you believe that your modem node should be included in KPPP's default list,
|
||
|
|
and you are using a common type of hardware, you can always file a wishlist
|
||
|
|
bug against the kppp package, although the package maintainers maintain the
|
||
|
|
right to judge your device node too esoteric for inclusion.
