interface not starting

[DJak]

Hello,

i´m having a problem while loading cipe module. After patching version 1.6.0
with patch for kernel 2.6.14 i could load module cipcb0 an got the following
messages in message file:

kernel: cipcb: CIPE driver vers 1.6.0 (c) Olaf Titz 1996-2003, 100 channels, \
debug=1
kernel: cipcb: cipe_alloc_dev 0

After that if i try to start the interface i got:

/etc/dev.d/net/50-ifup.dev[17524]: SIOCSIFFLAGS: No such device or address
ifup: Cannot enable interface cipcb0
ifup-route: interface cipcb0 is not up

Doing an ifconfig -a i can see cipcb0 but not without -a. So the interface was
not startet.

As i could not find any solution for this problem perhaps somebody can help me
with that.

Distribution: SuSE 9.2
Kernel: 2.6.15 from kernel.org

Regards and thanks in advance.

Dirk

The device won't be fully enabled until you have a ciped-cb daemon
running - and the daemon won't stay running until it has a peer to
talk to.

Rather than trying to access a device that's not really there yet, try
using it - bring up a tunnel, using pkcipe for example.

Hello,

well, my problem is that on my remote server there is no pkcipe running. It is
running a cipe daemon, waitiing for a connection. So i have to do it this
way. Using pkcipe means to use it on both sides i think (hopefully read
correct in documentation)?

Thanks for your answer.

First, an apology for my error in saying the ciped-cb daemon won't
stay running without a peer.  Static listening daemons have been used
for years - it's just been awhile since I last used one.

However, it is true that your cipcb0 device won't be fully enabled
until you have a daemon running.  If you simply load the module, it is
*normal* for ifconfig -a to show the cipcb0 device as neither UP nor
RUNNING.  Running the daemon (with a valid options file) will bring
the cipcb0 device the rest of the way up.

You can start the daemon without any ptpaddr or ipaddr options in the
options file and then do a manual ifconfig, but it's normal to let the
daemon assign the addresses.

Hello Dick,

thank you for your description.

Yes, ciped can run and i am able to start it now. I set it up with all
requested options and have now to set up correct routing to send the udp
packages through my dsl modem.

Regards.
