The Eicon Diva T/A is an external ISDN terminal adapter capable of MP,
BACP, and other niceties. Since it's external, it's just a serial device
as far as Linux is concerned. We've had good luck with it in the past.
However, one user is having a problem that baffles me.
The user is a dedicated 24x7 customer, and as such has a private BRI to
dial into. The channels on the BRI are not in hunt, and ComOS 3.7.2
doesn't do BACP, so he currently must dial two numbers (xxxxxxx&xxxxxxx).
When set for regular async-to-sync PPP (single channel), he can connect
just fine. However, he cannot login using MP. Judging from his pppd
debugging output, he's seeing continual LCP requests for MS-CHAP, which he
NAKs in favor of PAP. This is weird because ComOS doesn't do MS-CHAP (and
we don't even have regular CHAP enabled). It's even more weird because
debugging on the PM2 shows that we are only sending requests for PAP.
I should point out that in testing an identical Diva on my own Linux box
(kernel 2.0.36, pppd 2.2.0), it connects without a problem. The customer
is not willing to back down to a 2.0 kernel. The unit also has no problem
connecting from Windows (tested by us and by Eicon).
The customer has posted the problem to several Usenet newsgroups, and all
of the replies thus far thought it was absurd that Linux could be the
problem. Likewise, the folks at Eicon say their unit is not to blame.
And we all know that ComOS has never been capable of MS-CHAP, so it can't
be the problem.
If anyone has any experience with using the Diva on a Linux 2.2 system, I
would love to hear from you. I'm hoping that someone has had the same
problem, and hopefully found a solution. Thanks in advance.
