to pppd when using PAP authentication so that it can select the
appropriate secret from /etc/ppp/pap-secrets.
-Microsoft also has a variant of CHAP which they apparently think is
-more secure than standard CHAP because they don't store secrets in
-clear text on the server. However, a bogus client only needs to know
-the encrypted secret to gain access, so the only extra security is
-that the bogus client would need to run something other than Windows.
-There is a client-side implementation of Microsoft's CHAP in ppp-2.3;
-see README.MSCHAP80.

either.)

+Q: I get a message saying something like "ioctl(TIOCSETD): Operation
+not permitted". How do I fix this?
+
+A: This is because pppd is not running as root. If you have not
+installed pppd setuid-root, you will have to be root to run it. If
+you have installed pppd setuid-root and you still get this message, it
+is probably because your shell is using some other copy of pppd than
+the installed one - for example, if you are in the pppd directory
+where you've just built pppd and your $PATH has . before /usr/sbin (or
+wherever pppd gets installed).

Q: Has your package been ported to HP/UX or IRIX or AIX?
IRIX includes a good PPP implementation in the standard distribution,
as far as I know.

+
+Q: Under SunOS 4, when I try to modload the ppp modules, I get the
+message "can't open /dev/vd: No such device".
+
+A: First check in /dev that there is an entry like this:
+
+crw-r--r-- 1 root 57, 0 Oct 2 1991 vd
+
+If not, make one (mknod /dev/vd c 57 0). If the problem still exists,
+probably your kernel has been configured without the vd driver
+included. The vd driver is needed for loadable module support.
+
+First, identify the config file that was used. When you boot your
+machine, or if you run /etc/dmesg, you'll see a line that looks
+something like this:
+
+SunOS Release 4.1.3_U1 (CAP_XBOX) #7: Thu Mar 21 15:31:56 EST 1996
+ ^^^^^^^^
+ this is the config file name
+
+The config file will be in the /sys/`arch -k`/conf directory (arch -k
+should return sun4m for a SparcStation 10, sun3x for a Sun 3/80,
+etc.). Look in there for a line saying "options VDDRV". If that line
+isn't present (or is commented out), add it (or uncomment it).
+
+You then need to rebuild the kernel as described in the SunOS
+manuals. Basically you need to run config and make like this:
+
+ /usr/etc/config CAP_XBOX
+ cd ../CAP_XBOX
+ make
+
+(replacing the string CAP_XBOX by the name of the config file for your
+kernel, of course).
+
+Then copy the new kernel to /:
+
+ mv /vmunix /vmunix.working
+ cp vmunix /
+
+and reboot. Modload should then work.
+

+
+Q: I'm running Linux (or NetBSD or FreeBSD), and my system comes with
+PPP already. Should I consider installing this package? Why?
+
+A: The PPP that is already installed in your system is (or is derived
+from) some version of this PPP package. You can find out what version
+of this package is already installed with the command "pppd --help".
+If this is older than the latest version, you may wish to install the
+latest version so that you can take advantage of the new features or
+bug fixes.
