ioctl(PPPIOCGUNIT): Operation not permitted

[Peter Pilgrim <nospam [at] db.com>]

Hi

I recently changed distribution on my laptop computer from
Slackware 3.4 to SuSE Linux 6.1. I did a clean installation.
I am trying to get SuSE Linux to
connect to Demon Internet, but I keep getting errors
from `pppd' where it said `operation not permitted'
in the file `/var/log/messages'. I have also downloaded
latest `pppd' 2.5.8 and it still did not work. Here are the
messages:

pppd[345]: pppd 2.3.8 started by root, uid 0
pppd[345]: kernel tty_io.c process (345) pppd used obsolete
`/dev/cua2' up date software to use `/dev/ttyS2'
...
pppd[345]: Serial connection established
pppd[345]: ioctl(PPPIOCGUNIT): Operation not permitted
pppd[345]: tcsetattr: Operation not permitted
pppd[345]: Exit

I checked everything that I could think of. I made sure that I tried
to connect as the superuser. I checked that `/dev/modem' is
symbolically linked to `/dev/ttyS2'. I also checked that the access
permissions for the program `pppd' and device files were set to
`root'. I have no difficulty dialing up to my ISP with my modem, but
everytime the connection is completed, the `pppd' collapses. I suspect
that has something to do with the second message about the obsolete
`/dev/cua2'. I am clueless where to look next to solve this
ioctl(PPPIOCGUNIT)
problem and I exhausted the suse-linux-en [at] suse.com list

I have also done

find /etc -follow -type f -print | xargs grep -n cua

rm /dev/modem
ln -s /dev/ttyS2 /dev/modem

/etc/pcmcia/serial stop cua2
/etc/pcmcia/serial start ttyS2

I also did `grep cua2 /etc/rc.config'
and then `find /etc -follow -type f -print | xargs grep -n /dev/cua'
but could find nothing.

I also checked the `MODEM=/dev/ttyS2' was set in /etc/rc.config

Any help greatly appreciated.
