Dear All I have already post this on the pptpclient list, but it may be also useful to let Fedora Core community know about this. I have just updated the kernel to 2.6.13-1.1526_FC4, and now I cannot use pptpconfig, getting the following error: /usr/sbin/pppd: This system lacks kernel support for PPP. This could be because the PPP kernel module could not be loaded, or because PPP was not included in the kernel configuration. If PPP was included as a module, try `/sbin/modprobe -v ppp'. If that fails, check that ppp.o exists in /lib/modules/`uname -r`/net. See README.linux file in the ppp distribution for more details. pptpconfig: pppd process terminated by signal 4 (failed) pptpconfig: SIGILL Regards, Paul
