Hi,
I'm trying to set up mpd (3.18) on a FreeBSD server to allow windows and
linux clients to connect. Currently I've only been trying to make the
linux connection succeed (Ubuntu with ppp-2.4.4), but I get the
following output from the linux pppd client:
CHAP authentication succeeded
sent [CCP ConfReq id=0x1 <mppe +H -M +S -L -D -C>]
rcvd [IPCP ConfReq id=0x1 <addr 10.0.0.1> <compress VJ 0f 00>]
sent [IPCP TermAck id=0x1]
rcvd [CCP ConfReq id=0x1 <mppe +H -M +S -L -D -C>]
sent [CCP ConfAck id=0x1 <mppe +H -M +S -L -D -C>]
rcvd [CCP ConfRej id=0x1 <mppe +H -M +S -L -D -C>]
MPPE required but peer refused
sent [LCP TermReq id=0x2 "MPPE required but peer refused"]
rcvd [LCP TermAck id=0x4]
Connection terminated.
I don't understand why the linux client sends a TermAck on IPCP without
getting a TermReq first, but apart from that mpd seems to be failing to
negotiate mppe even though I configured mpd to allow ONLY mppe-128,
i.e., in my mpd.conf I have the following:
# Microsoft Point to Point Encryption
set bundle enable compression
set ccp enable mppc
set ccp enable mpp-e128
set ccp yes mpp-stateless
set ccp no mpp-e40
Am I doing something obviously wrong? Does anybody know how to fix this
problem? Any advice is welcome!
Thanks in advance,
Sebastiaan
P.S.: I have attached the mpd.conf, mpd.links, mpd.log and ppp.log files
for completeness.
