Using Linuxconf in RedHat 6.0, I could connect to the world wide web with ppp0, then I also could connect using the AnotherLevel Usernet applet, as recommended in the "Getting Started" book. However, I could not disconnect from ISP except by halting the RedHat session. Not a desirable solution. What should I do?
This problem shows up with some ISPs and some modems, and I do not know what all combinations provoke it. Some people see it regularily, some rarely, and some never. For Red Hat Linux 6.1, I re-architected the PPP management so that ifup and ifdown are both very reliable. Unfortunately, I do not know if you can just drop the new initscripts package in place on Red Hat Linux 6.0. There is really no way to fix this without the new architecture. If you like, you can try installing the new initscripts package from Red Hat Linux 6.1 on your Red Hat Linux 6.0 system and see if it works; if you do try it, have the old initscripts package ready to revert to if it breaks anything.
