[Pppext] IPCP Negotiation Failure

[amyng <ang at shoppertrak.com>]

Apology if this is not the correct forum, but I'm on my last straw.

I'm running 2.4.4 pppd on Solaris trying to connect to a device (which I can
get to by window rasppp btw).

After receiving "Could not determine local IP address" IPCP confReq (see
following ppp log)...

$ pppd options in effect:

I specified the local IP address in /etc/ppp/options and got a different
error:

I have an output of a successful ppp connection from the same pppd connected
to a similar device using the same options:
$ pppd options in effect:
debug           # (from /etc/ppp/options)
kdebug 31               # (from /etc/ppp/options)

local  IP address 192.168.129.2
remote IP address 192.168.129.1

I noticed that the failure case, the last IPCP ConfReq is sent without the
specified local IP Address:
sent [IPCP ConfReq id=0x2]
whereas the successful case, it does:
sent [IPCP ConfReq id=0x2 <addr 192.168.129.2>]

Any help would be greatly appreciated!!
