[gentoo-user] ISDN problems

[gentoo-user] ISDN problems

[Alex Schuster]

Hi there!

I am having big trouble setting up ISDN. I'm a long-time ISDN user, I need 
this for connecting to some remote systems that do not have an internet 
connection. I always used my server for this, but due to a sudden 
breakdown of phone+dsl on that machine (which is far away, I have no 
physical access), I tried setting up ISDN on my machine here. BTW, all 
machines on which I have set up ISDN have AVM Fritz PCI cards.

Trouble, big trouble. Normally, it should be just a matter of emerging 
fcpci for the fcpci.ko kernel module, emerge capi4k-utils, edit a line in 
/etc/capi.conf to define my card, then create a little config in 
/etc/ppp/peers, and set the PAP login data in /etc/ppp/pap-secrets. But 
that does not work now.

net-dialup/fcpci does not compile, but I found a patch on bugs.gentoo.org, 
and the module seems to load file. Apart from a message ("IRQ 20/fcpci: 
IRQF_DISABLED is not guaranteed on shared IRQs"), but I saw thsi in some 
other howtos, so it's probably not a problem.

But /etc/init.d/capi fails to start, when calling 'capiinit activate':
ERROR: cannot open /dev/capi20 nor /dev/isdn/capi20 - No such device or 
address (6)

This file is existing:
crw------- 1 root root 191, 20 22. Jun 23:35 /dev/capi20

Changing permissions does not help.

I also tried the other kernel modules, net-dialup/fritzcapi, but that does 
not build either - it does not find linux/auconf.h. Huh? I have this in 
/usr/lib64/klibc/include/ only. On other Gentoo systems, this should be in 
the kernel's include directory. Maybe 2.6.33 is too new for that?

Then I tried mISDN, and guess what, it also does not compile at all. There 
is a bug report (#265581), but its over a year old without progress.

So I downloaded mISDN and built it according to http://www.misdn.org/, 
which seemed to work. But I get the same capi error. So it's probably not 
a problem with the ISDN card kernel driver, but with the CAPI setup.

I'm out of ideas. What's wrong with /dev/capi20?

I'd got the same message while setting up a hylafax-server. I solved it 
by creating a new 50-udev.rules:

###
~ $ cat /etc/udev/rules.d/50-udev.rules
KERNEL=="capi",                 NAME="capi20", SYMLINK+="isdn/capi20 
faxCAPI", GROUP="uucp", MODE="0666"
KERNEL=="capi[0-9]*",           NAME="capi/%n"
~ $
###
You may waive the faxCAPI-directive.


###
~ # capiinit status
1 fcpci      running  fcpci-bc00-17    A1 3.11-07 0xbc00 17

###
~ $ faxstat

Sorry for not responding until now. My imminent ISDN problem was 
workarounded, I got access to a machineI could use for that. And then my 
phone problem was finally fixed, so I again have a PC I can use for that. 
But I will shut it down soon, it's too much of a waste fo energy to let it 
run only for being able to use it for ISDN, and das server for CVS and my 
Wiki.

I first thougt your suggestions would just adjust the permissions, and 
that does not seem to be the real problem, but I tried anyway, and got a 
partial success! The error message is gone, and capiinfo shows stuff. 
Thanks!

But still, pppd call <peer> does not work. The system seems to be dialing, 
I see familiar messages, but that's it, no more messages at all.

When I just tried that again, the system even hung, I could not even 
switch to a text shell, I had to reset. I suspected this had to do with 
multiple drivers being loaded, these are running after system startup:

weird ~ # lsmod|grep -i isdn
mISDNipac              17480  1 avmfritz
mISDN_core             78152  3 avmfritz,mISDNipac

But I just tried again, after removing all avmfritz and mISDN modules. The 
last message I get is:
capiplugin: using /dev/capi/0: "" -> "022112345678" outgoing  (pcli=...)

I removed all modules again, commented out fcpci in /etc/capi.conf and 
enabled avmfritz, started capi. But then capiinfo again gives the "capi 
not installed" message.

I'm not sure what to do now, maybe have a deeper look at the mISDN 
project. Why can't these things just keep working? And even worse, they 
make my PC crash, which makes trying around further no joy.

Strange anough, I was able to dial to the arcor peer, which is an example 
that comes with capi4kutils. When using the same file, except with 
different number, user and password, the system hangs. Sort of. When in 
text mode, I can still switch terminals, and it also works when using 
screen. I can also enter text, but the enter key does nothing, and 
ctrl-{C,D,Z} also do nothing.

Whatever.

I upgraded to tuxonice-sources-2.6.34, removed a single line in the fcpci 
sources which made them not compile, and now all is working just as 
expected.

Should the ownership be different than root:root perhaps?  e.g. have you tried 
root:tty, or root:dialup, or root:uucp, or whichever group is appropriate for 
ISDN?
