Greetings,
I have an unusual problem with diald. Our team has setup a system whereby
engineers may dial directly into a customer's server to support it. We utilize
Win98 and NT 4.0 clients running a VB program that calls scripts via rsh to
create a connection via diald on our
Linux dialout server, which contains kernel 2.2, Red Hat 5.2, Diald 0.16, and,
Chat 1.17.
All customers have identical NT servers, with identical setups.
We currently support 50+ sites and diald has proven to be an excellent piece of
software for gaining access to a customer's server. I was hoping for some
feedback concerning the following specific behavior:
Three sites that we connect to, all with identical configuration/script files
as any other site we support (except the IP addressess and secrets of course)
have the ppp daemon returning our Linux dialout server gateway address, rather
than the supplied local IP address after a connection has been established. I
have tried sleeps at various points throughout the scripts, adding the keyword
'dynamic' to the site's diald config files, as well as, pausing the VB program
to allow scripts to complete their runs.
I have also tried substituting the local IP addresses of these three sites with
another site's local IP that returns the correct local IP after a connection.
The ppp daemon returns that a connection has been made and that the host local
IP is correct. Once I use the correct local IP address, our local gateway is
returned (?).
I have consulted the man pages and read some rfc to try and understand this
behavior to no avail. I'm just at the 'comfortable' stage with Linux and am by
no means a pro with this OS... ok, ok, I'm in the wannabe stage - so teach me!
<g>
All the IP addressess are class III, and below I have listed samples of
scripts. Any help you may have on this would be greatly appreciated!
Thanks in advance,
-Brady

Configuration file used by my VB program for users to dial remote sites.
Users click site they want and underlying call to rshell runs appropriate
script
-------------------------------------------------------------------------------
----------
#Each site has an associate diald file using the File <Name> below for a
reference
#File Phone Number Primary IP Display Name Server
"Site_1","9,1,800,5551212","255.0.0.0","Steel and Stuff","DIALOUTSERVER"
"Site_2","9,1,888,1234567","255.255.0.0","Plastics-r-us","DIALOUTSERVER"
"Site_3","9,1,900,9998888","255.255.255.0","CustomerMoneyBags","DIALOUTSERVER"
-------------------------------------------------------------------------------

Chap-Secrets file - Nothing special here; customer sites have matching secrets.
(Handshakes work perfectly - all sites are configured identically)
-------------------------------------------------------------------------------
----------
# client server secret
DIALOUTSERVER Site_1_Server Secret_1
DIALOUTSERVER Site_2_Server Secret_2
DIALOUTSERVER Site_3_Server Secret_3
-------------------------------------------------------------------------------
----------
Chat file - again, pretty simple, just assign the applicable environment
variables.
(Chat never errors out - sites connect, but IP address returned is our gateway,
not the local IP address we need to thread through a customers network).
-------------------------------------------------------------------------------

#!/bin/sh
# PPP connection script for Steel and Stuff
PHONE_NUMBER="9,1,800,5551212"
SITE_NAME="Site_1"
. /etc/diald/chat.dialer.ppp
-------------------------------------------------------------------------------
----------
chat.dialer.ppp script - The VB user program also uses the report for last
connect time and connect speed or a site.
-------------------------------------------------------------------------------
----------
# -r == report using stderr
chat -r /var/log/diald.$SITE_NAME.connect
-------------------------------------------------------------------------------
----------
conf.Site_1 - This works fine for all but three of 50+ sites we dial directly
into...

Last but not least, here's a 'ps x' screen dump. Of course, all IP's have been
changed to protect the innocent <g>. All the FIFOs have been established, and
dialing out works great except for three sites. The server is very clean, only
the bare necessities loaded.
