Hi all!

I'm trying to connect a FreeBSD 2.2.6 box to a AIX system with user PPP.

The AIX box is setup as follows:

- there's a user with a regular login

- in his .profile there's: 
  "exec /usr/sbin/pppattachd server 2>/dev/null"

- the interface config for PPP is:

	interface
	server
	local_ip  10.8.11.240
	remote_ip 10.8.11.245
	netmask   255.155.155.0

It's AIX version 4.1.5.0 and the above is what the AIX manual suggested.
This worked out of the box with Windows 95 as a client.


I set up FreeBSD /etc/ppp/ppp.conf like this:

default:
	set device /dev/cuaa0
	set speed 19200
	disable pred1
	deny pred1
	disable lqr
	deny lqr
	set redial 30 3
	set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \"\" AT&FX3 OK-AT-OK \\dATDT\\T TIMEOUT 120 CONNECT"

blabla:
	set log chat lcp ipcp
	set phone 0w0033387282534
	set timeout 300
	set openmode active
	set login "TIMEOUT 30 ogin:-\\r-ogin: blabla ennwort foobar"
	set ifaddr 10.8.11.245/32 10.8.11.240/32 255.255.255.0

(Don't be fooled by the "ennwort" - this stupid thing asks for the
 password in German ;-)

Now, when I try to use 57600 or 38400 DTE speed, even the login fails.
When I use 19200, login, lcp and ipcp seem to work:

But, when I try to ping, the modem transmit LED flashes, but i don't get
an echo back. The admin on the other side isn't too Unix experienced,
but from what he told me, his routing table looked OK. The interfaces
on both sides seemed to be up, the routes correct - but noone could
ping the other end.


Any suggestions?

Patrick
