has anyone gotten PPP and MPPE working with kernel 2.6.x yet??

[Jeffrey D. Means]

I am running kernel 2.6.5 and having a strange error message when I try
to start my ppp daemon about MPPE not available I am trying to use
PopTop 1.1.3 with pppd 2.4.2

In my mind this looks like a bug with the 2.6 kernel or could it be a
bug with pppd??

The radius plugin did not provide key material during the
authentication, and so MPPE cannot be started.

In my mind it looks to be a bug with the radius plugin, or a
misconfiguration of the radius pppd options leading to the result
observed.  I don't see any evidence of kernel being the cause, yet.

(Perhaps it worked before but didn't after upgrade of only the kernel?
If you upgraded pppd or the radius plugin, I'd suspect it more than the
kernel.)

nope just upgraded kernel and pppd same config files used for pppd and
radius

It might be a radius plugin incompatibility with 2.6.  It needs further
investigation by someone who uses the plugin.  Try the PPTP mailing
lists, I know some radius and pptpd users lurk there.  Perhaps someone
else on the PPP list will respond.

But I can answer the question in your subject; I've been using MPPE with
2.6.5 for quite a few weeks, without problems.
