I have successfully configured our main Aix box to be a PPP server. We are
able to dial into the Aix box from home via Win95 and access other Aix boxes
on LAN as well as having access to the Internet.

However, I cannot access any NT Servers or Win95 Workstations on the LAN,
eg. either via "Network Neighborhood" or "Mapping a Network Drive". On my
home PC I have enabled all the protocols, ie. NetBEUI, IPX/SPX and TCP/IP,
in my "dial-up networking" utility, but I still cannot access any NT/Win95
boxes.

Is it possible to access the NT/Win95 boxes via an Aix PPP session ???
How do you do it ??

I know you can dial into an NT Server and you'll have access to the rest of
the LAN, but I hoping to keep the PPP link on the AIX box.

Any help would be appreciated.

This is a common problem with Windoze. The problem is that the MS
stuff uses UDP broadcast messages from the servers in order to locate
them on the client. Of course, those broadcasts aren't normally
forwarded across the PPP links, so the PPP users don't see the
servers.

It would be pretty easy to write a little applicate to listen for
broadcasts on UDP ports 137, 138, and 139, and then read the AIX
kernel interface tables and forward the datagrams out to all the
dial-up users ...

Try putting the IP address of an NT server in the file LMHOSTS (there is
already an lmhosts.sam in your windows directory)

For testing the connection you could also use the command nbtstat -A
ip-adres-of-server to check if you could get to the NT server.

Dear Bill,
I've tried under AIX 4.3.1 to setup dialin PPP from the 'cookbook'
instructions on the IBM AIX web site but it doesn't work for me. I am most
probably interpreting these instructions wrong but when you set up ppp, was
there anything you needed to do outside of IBM's normal setup to get it to
work? When I login as 'pppuser', the cookbook says I should see a line of
'garbage' on my screen as the system tries to do authentication and
eventually be presented with a login prompt. I don't get either of these.

Any suggestions would be appreciated.
Thanks!

Ken,

is pppcontrold running?
If you do netstat -in do you see your pp# network interfaces?
In your PPP user's .profile do you have:
exec /usr/sbin/pppattachd server

If that fails, ppp will put some debugging output to syslog. I
believe there are signals that can be sent to the pppcontrold
process to enable and disable detailed debugging (ie
kill -## process ID to enable or disable the debugging)

Regards,
Paul

Given that the "line of garbage" is not coming out (assuming that the original
poster is using
a terminal emulator program to login to AIX and not expecting the PPP protocol
information
to be showing in the dialup message) it is most likely that the .profile is not
execing the attachment
daemon.

To put full debugging to syslog (assuming that daemon.debug facility is enabled
in the syslog.conf
file) send SIGUSR1 (SIGUSR2 will turn it off). This works to PPPcontrold and
PPPauthd. The
attachd is pretty stupid and just connects the streams.
