Aug 21 0329 server pppd[25615]: 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.
