Re: Win95 Dial-in Clients

Hi Bryan,

I've tried to annotate the (portion?) of the log you sent
based on my (limited?) understanding of what is happing.

Is this the full transcript?
It looks as if at least some LCP stuff is missing (but probably not =
important).

Is the client using a login script instead of PAP?
Did you just choose not to broadcast the users name & password?
It looks like the PAP exchange is missing (but probably not important).

=46inally, it seems that the client (Win95) seems to just give up when
the PM rejects it's request for NBNSs and SecDNS. It usually
just sends another IPCP Request leaving them out.
Could there have been more output that didn't make it
into your posting?

Puzzled,
Bill

Win95 asks PM to talk to it using these LCP opts.

Usually this comes in response to another conf req from Win95.
Notice this a reply to req #2. Where is req #2?

>Skipping: S7: LCP Open

The firmware on the PM recognizes that the LCP negotiation
has converged.

Normally PAP takes place now.
Is this client set up to use some login script instead of PAP?

Win95 says: Please use VJC and tell me addresses for these
other 5 things. Win95 seems to ask for the Netbio NSs even
if WINS is disabled; although puzzling, it is normal.

PM says: I can't tell you the addresses for these.

At this point Win95 normally responds with another IPCP Req
containing only VJC, IP adr, and Pri DNS addr.
Don't know why it wouldn't.
