Yes, when I say "his" address, I'm referring to the ISP.
Here's my ppp.conf...
default:
set log Phase Chat LCP IPCP CCP tun command
set device /dev/cuaa0
set speed 19200
set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT (wrapped)
5 \"\" AT OK-AT-OK ATE1Q0 OK \\dATDT\\T TIMEOUT 40 CONNECT"
allow users djp sybase
ExecPC:
set phone 9686400|8306240
set login
set authname uid
set authkey pwd
set timeout 600
set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.0 0.0.0.0
add default HISADDR
enable dns

Do you mean /dev/cuaa0?. It's an external modem, it dials,
handshakes and the proper lights are blinking. I run either
interactively or with -background or -auto switches and it
get connected. I'm verifying the assignment of IP addresses
with ifconfig. Here's an example:
% ifconfig -u tun0
tun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1514
inet 169.207.24.236 --> 169.207.111.79 netmask 0xffff0000
so I assume the device is initialized. Here's a netstat
% netstat -rn
Routing tables
Internet:
Destination Gateway Flags Refs Use Netif Expire
default 169.207.111.79 UGSc 2 0 tun0
10.20/16 link#1 UC 0 0 ed0
10.20.10.28 0:10:5a:d3:cf:a1 UHLW 1 132 ed0 1129

Yes. Here's rc.conf...

moused_enable="NO"
saver="fade"
blanktime="300"
keyrate="fast"

ifconfig_ed0="inet 10.20.1.121 netmask 255.255.0.0"
# gateway_enable="YES"
hostname="canaan.newresources.com"
Here's resolv.conf... Note: these are all ISP entries,
nothing from my LAN
% cat /etc/resolv.conf
domain execpc.com
nameserver 169.207.1.3
nameserver 204.29.202.6
Here's hosts
% cat /etc/hosts
127.0.0.1 localhost.newresources.com localhost
10.20.1.121 canaan.newresources.com canaan
10.20.1.121 canaan.newresources.com.

The machine is running on a corporate intranet behind a novell
firewall. The addresses you see in netstat and ifconfig are real.
User ppp was working until about two weeks ago. I had an
unexpected power interruption (I accidentally pulled the
wrong plug out of a power strip). This was on a Friday after-
noon and when I think back on it, I don't think ppp has worked
since then, but I won't swear it happened then.
Could a file or device have been corrupted?
I'm wondering if somehow the IP requests are being routed not
through tun0 but ed0. The blasted novell firewall only allows
http requests through, thus my need to dial out.
Thanks for your help!
