Re: pppd fails when init connection with kernel 2-6-28.10

[Sonia <xonia10@yahoo.es>]

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
