A2. Upgrade pppd on Fedora Core 4 / 5 / 6

A2.1 Fedora 5 and 6
(last update: 19 May 2007)

FC5 comes with ppp-2.4.3-6.2.1 and FC6 has ppp-2.4.4-1. MPPE support is already enabled. If ppp is not installed, use yum to install it.

[root@pptp ~]# yum install ppp

Note: Information on how to update ppp module on FC4 is in the next section.

A2.2 Fedora Core 4
(last update: 6 March 2006)

FC4 comes with ppp-2.4.2-7. It is required to be upgraded to a patched version which supports MPPE. The patched version can be found in here. Download the rpm for FC4. At the time of writing, the latest version is 2.4.3-5. Get the FC4 rpm:

ppp-2.4.3-5.fc4.i386.rpm

Upgrade the ppp with the downloaded version:

[root@pptp ~]# rpm -Uvh ppp-2.4.3-5.fc4.i386.rpm

Note: If you are a Gentoo user, and are using kernel v2.6.15, the ppp-2.4.3-5 does NOT work because of MPPC. You may find more information from here.
