[pptp-server] GRE: read error: Protocol not available

[George Vieira]

He most likely only supports 40bit encryption.. he might have to download
DUN1.4 from microsoft and update it.
Did you compile your PPPD driver as a module or built into the kernel?
Can you paste a small section of a complete pppd connection which fails..?

hey, 

i am getting inconsistent errors. some times i get the error " Error with
select (), quitting" 
and some other times, i get the error " PTY read or GRE write failed" 
i am using kernel 2.4.6, ppp 2.4.1 and pptp 1.0.1 , 1.1.2 ( i had been
getting the same problem with both). 
client is win 98 machine ppp link is fine with mppe -40 encryption. 
also, if i enable only "mppe-128" on the server, he fails to connect. 
any ideas?

in an hours time if the changes I did may have helped or not...

Hey peeps,Rebuilding my firewall and reinstalling all the patches etc for
Kernel 2.4.16 and pppd 2.4.1 but I got errors when connecting about a
protocol not avialable.. I assume it's GRE as below.Which options could this
be in the kernel? Should it be a module or built into the kernel? It's been
a while since I've built kernels and done anything with pptp.....argh!Dec 10
