I gonna add this rule to udev-113-r1, but that will not solve this problem. It just will prevent the device from disappearing after rmmod ppp_generic. KERNEL=="ppp", MODE="0600", OPTIONS+="ignore_remove" How do you use /dev/ppp? By using some baselayout net-scripts like net.ppp0? Or by yourself calling pppd. In later case I suggest adding correct ppp module to modules.autoload.d, or adding modprobe into the script calling pppd.

I use wvdial to work with modem and pptp to start VPN over ethernet. Adding ppp_generic to autoload looks like help, and it is more clean solution than my adding call of mknod to start scripts. But so if I create device inode using mknod, udev can in every moment just delete it? >By using some baselayout net-scripts like net.ppp0?

debian's udev start script does create this at boot? should we also do this?
So why can't wvdial load the modules itself if /dev/ppp0 is not present?
Correction: there is no such device /dev/ppp0. The only related device is /dev/ppp. The device can be created by loading ppp_generic module, which IMO should be done by pppd. Questions are: a) Does anyone have objections about that? b) What command line do you think is more appropriate, "modprobe -q ppp_generic" or "modprobe -q /dev/ppp" ?
wvdial is just establish connection, and when all done, call pppd, pppd if /dev/ppp not present, say: Feb 25 11:24:50 rain pppd[17182]: pppd is unable to open the /dev/ppp device. You need to create the /dev/ppp device node by executing the following command as root: mknod /dev/ppp c 108 0 and exit
net-dialup/ppp-2.4.4-r10 solves this issue through dev-ppp patch. Feel free to close this bug.

(In reply to comment #13) This doesn't help me much. See if: a) you have ppp_generic kernel module b) /dev/ppp gets created by udev when you run modprobe ppp_generic. Be sure it isn't already loaded (lsmod | grep ppp_generic) before running the aforementioned command.

Ups... seems modprobe ends before creation of the ppp device, which results in pppd's failure when executed for the first time. Udev peeps, please advise. Should I run "modprobe -q ppp_generic" then sleep for 1 second if /dev/ppp don't exist?
The second, even more ugly possibility is: mknod /dev/ppp when it is needed, it will then trigger kernel to do modprobe when opened.
The source already contains something like that, but is excluded from compilation by a #if 0: fd = open("/dev/ppp", O_RDWR); #if 0 if (fd < 0 && errno == ENOENT) { /* try making it and see if that helps. */ if (mknod("/dev/ppp", S_IFCHR | S_IRUSR | S_IWUSR, makedev(108, 0)) >= 0) { fd = open("/dev/ppp", O_RDWR); if (fd >= 0) info("Created /dev/ppp device node"); else unlink("/dev/ppp"); /* didn't work, undo the mknod */ } else if (errno == EEXIST) { fd = open("/dev/ppp", O_RDWR); } } #endif /* 0 */ I could simply remove the #if 0 and add S_IRGRP | S_IWGRP to the permissions mask.
Fixed in ppp-2.4.4-r11 by using the solution presented in comment 18.
