This is probably a Bad Idea. Try maxusers 16 or maxusers 32. If these boxes are JUST doing ppp, the original maxusers 10 is actually probably just fine. Setting maxusers too high will lead to high kernel memory utilization - you are wasting memory. This could potentially cause a panic, but I have no idea if it would be the panic that you are seeing. > the /etc/ttys is > > ttyc0 "/usr/libexec/getty std.38400" unknown on secure > for the CYCLOM terminals > > ttyd4 "/usr/libexec/getty std.38400" unknown on secure > for Musa terminals > > I tried to change "unknown" to dialup, but nothing changed. Makes no difference. That is the initial setting of the TERM environment variable. ... JG
