Upgraded. But, I have unit 3 in options file (tried at the
command line also), but still:

pppd[10697]: Using interface ppp1

Yep.  That fix has been suggested for some other problem as well and seems
better.

Well, then I do not know. The unit option works such that the system
tries to use the requested unit, but if that is not available, it will
just ask for the next available unit. So there may be some reason why 3
is not available, or perhaps your kernel ppp deos not allow anything but
the next unit number (you never did tell us which kernel youwere
running-- sounds like a very old one), but I have no idea if that is the
problem.

linux /dev/ppp question

Does anyone know why the 2.2.x linux kernel does not require the creation of
the /dev/ppp and the "new driver" in the 2.4.x kernel does? I read the
documentation and looked at the pppd source, but that did not make it any
clearer.
Thanks,
dbg

It's almost certainly the problem.  The 2.4.0 kernel was the only one of
the 2.4.x series that pppd 2.3.11 could run under, and the 2.2.x kernel
series doesn't have kernel support for the "unit <n>" option.

I tried unit 2 - the same problem. Sorry about the kernel version, I wanted
to tell it, but forgot. It's 2.2.22 SMP, RH 6.2. Probably unit works only
with 2.4 kernels. OK, just tried 'unit 2' with 2.4 - it works. Is it possible
to make it work with 2.2 kernels also?

Nerijus

The kernel driver was completely rewritten for 2.4
 However what the detailed reasons for the different hook into the
 kernel driver I do not know.

Yes, upgrade to 2.4.
Or you could spend the next year of your life figuring out how to fit
the completely rewritten kernel ppp code of the 2.4 series into a 2.2
kernel. I think the first is easier.

I hope you are keeping up with the all the security updates for Redhat
6.2 as well.

Probably ;-)

Yes, but this has nothing to do with the subject.

Another problem, but probably specific to Red Hat, so I don't know if
anyone can help.

RH has /etc/ppp/ip-up, which calls ip-up.local if it exists when ppp
is up. I have in ip-up.local:

REALDEVICE=$1
PTP=$5

if [ "$REALDEVICE" = "ppp0" ]
then echo "$PTP" > /var/run/ppp0-ptp
fi
if [ "$REALDEVICE" = "ppp1" ]
then echo "$PTP" > /var/run/ppp1-ptp
fi

ppp0 is used by pppoe (roaringpenguin), ppp1 - dialup. The problem is,
that /var/run/ppp0-ptp contains only new line when ppp0 is up, while
/var/run/ppp1-ptp correctly has IP address of a gateway (P-t-P).
It is on the same system (RH 6.2).

There is no such problem on another system (RH 7.2) - when adsl comes
up, gateway gets written to /var/run/ppp0-ptp.

Regards,
Nerijus

Re: [PATCH] pppd/persist, linux 2.14.19+ - PPPIOCDETACH error

  There are probably things that this would fix, but I don't think it 
would help here, as I mentioned in my previous reply. The existing code 
in run_program() already closes the fd before it does the execve(). We 
just need to be sure that's done before the parent process proceeds. I'm 
sure my approach isn't the only way to do that (but it's worked 
flawlessly for me so far) - anyone care to suggest a better way?

BTW - I realised that I had malloc'ed the sigaction struct but forgotten 
to free it - there needs to be a call to free(tidysig) right after the 
pause().
