Hi!
I think i found bug in CBCP support in pppd 2.3.5.
When used AdminDefined Call Back I take:
rcvd [CBCP Request id=0x63 < AdminDefined delay = 0>]
length: 3
user admin defined allowed
cbcp_resp cb_type=8
cbcp_resp CONF_ADMIN
sent [CBCP Response id=0x63 < AdminDefined delay = 5 number = >]
rcvd [CBCP Request id=0x64 < AdminDefined delay = 0>]
length: 3
user admin defined allowed
cbcp_resp cb_type=8
cbcp_resp CONF_ADMIN
sent [CBCP Response id=0x64 < AdminDefined delay = 5 number = >]
rcvd [CBCP Request id=0x65 < AdminDefined delay = 0>]
Looks like pppd sends one byte more then required.
After applying patch i got normal connection:
rcvd [CBCP Request id=0x3d < AdminDefined delay = 0>]
length: 3
user admin defined allowed
cbcp_resp cb_type=8
cbcp_resp CONF_ADMIN
sent [CBCP Response id=0x3d < AdminDefined delay = 5>]
rcvd [CBCP Ack id=0x3e < AdminDefined delay = 5>]
id doesn't match: expected 61 recv 62
sent [LCP TermReq id=0x2 "Call me back, please"]
rcvd [LCP TermAck id=0x2]
May be this patch need to be commited into FreeBSD STABLE?
