PPP to MS RRAS Server Protocol errors

PPP to MS RRAS Server Protocol errors

[Rick Blair]

hi all,

I can connect to a microsoft RRAS server on Windows 2003 server.

Setup Fedora 15 64 bit 
Kernel 2.6.41.10-3

I am using wvdial

I successfully authenticate with MS-CHAP V2

PPP options
nobsdcomp
refuse-eap
require-mppe-128
mppe-stateful
noaccomp
nodeflate
nopcomp


Everything looks good,  except every packet I receive from the windows box I get
Unsupported protocol xxxxx received

where xxx seems to have a fairly random value.
Any clues?

Thanks

I've ran in similar trouble a year ago. The difference in my case was
that I was connecting from windows box to linux server, but the issue
seems to be same.

You can look at my original post to this mail list here:
http://marc.info/?l=linux-ppp&m\x129753728204109&w=2

But I had no response to that. It seems, nobody here is interested in
getting stateful mppe encryption work. MPPE stateless mode works good,
however.

Try the pptp specific lists (client and poptop server). Provide more 
information when you do (use "verbose" flag).

It's not only PPtP specific. It's a PPP-specific (both PPP daemon and
kernel module levels), which also affects PPPoE and possibly other
underneath transport types.

Maybe so, but you've already noticed that "nobody here is interested in 
getting stateful mppe encryption [to] work". If you want to find such 
people, try the pptp specific lists.
