Adding traces to pppd all I can see is a warning in pppd/main.c
pppdb = tdb_open(_PATH_PPPDB, 0, 0, O_RDWR|O_CREAT, 0644);
Warning: couldn't open ppp database /var/run/ppp/pppd2.tdb
Although the file exists in the file system:
# ls -l /var/run/ppp/
-rw-r--r-- 1 0 pppd2.tdb
And the error getting the channel with ioctl in pppd/sys_linux.c in function generic_establish_ppp:
if (ioctl(fd, PPPIOCGCHAN, &chindex) == -1) {
error("Couldn't get channel %d from %d",chindex,fd );
goto err;
}
But I don't know if this error is causing the signal or only an effect of the signal,
Thank you in advance,
Sonia
