Description rbiern01 2000-01-10 16:30:11 EST
I have set up my redhat 6.0 box for incoming PPP connections using mgetty
and pppd with Chap aithentication. When a win98 dialup client trys to
conect, they appear connected from thir end however they cannot ping
anything because of timeouts. The /var/log/messages goes crazy while the
win98 clients are connected and just keeps printing out the following
until they hang up

pppd[1080]: Protocol-Reject for unsupported protocol 0x7263

protocol 0x5072

I dont have any problems like this if someone using NT dials in and they
can use the internet fine.

From my reading of the IANA PPP assigned numbers list
(http://www.isi.edu/in-notes/iana/assignments/ppp-numbers),
it appears that protocol 0x73 is MP+, a protocol related
to bandwidth management.  Protocols 0x5072 and 0x7263 is
an unregistered non-standard protocol.

This is similar to bug 8254.  Do the clients have any additional client
software installed (VPN, PPTP, etc)?  Documentation on the peculiarities
of the Windows 98 TCP/IP stack is pretty scarce, unfortunately.

Closing due to old age.
