dev/modem link keeps vanishing in SUSE 10.0

I had been using the netzero dialer (from the netzero.deb) package sucessfully with SUSE 9.2, under the sudo program in my user directory. I then installed SUSE 10.0 as an update. The same arrangement still works with netzero, but I have to almost continually re-define the modem with YAST, because the modem link file keeps vanishing (/dev/modem). I don't understand this. Anybody know a workaround? I hope it's not re-installing v. 10 from scratch, instead of as an update.

SuSE 10 is probably setup for udev, which dynamically creates dev links as needed. In /etc/udev, you would have to edit the udev.rules to have udev create the link for you when needed.

The alternative is to reconfigure for static dev, which does not remove links when no longer needed.

Thanks for putting me on the right track. I bogged down in studying man udev for a while, and found a web page for writing udev rules. I finally found the recipe I needed in a ubuntu forum, using google. What I needed was a file named 10-local.rules placed in the /sda3/etc/udev/rules.d subdirectory. All the file needed was the line following:

KERNEL="ttyS1", SYMLINK="modem"

Now the modem node in the /dev directory doesn't vanish anymore.

Thanks DeekBeek. I was having the exact same problem.

Thanks DeekBeek
I've had the same problem too.

I'm embarrassed about being thanked, here, since I really had no idea that udev was the problem (bigrigdriver pointed it out). Google found the rest. Funny code module, that udev, kind of hyperactive (at least in the default state SUSE 10.0 installs it).
