Yes, it looks good.

I use the following to connect via User PPP.
:::::::::::::
/etc/ppp/ppp.conf
:::::::::::::
default:
set device /dev/cuaa0
set log Phase Chat LCP IPCP CCP tun command
set speed 115200
set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \"\" AT OK-AT-OK ATE1Q0 OK \\dATDT\\T TIMEOUT 40 CONNECT"
ISP:
set timeout 120
# 888 str is my IP (static), 777 is the ISP's gw box
set ifaddr 888.88.888.88 777.7.7.777 255.255.255.0 0.0.0.0
# Here is the primary NS / gw
add default 777.7.0.7 777.7.0.777
# Here is the 2nd NS / gw
add 777.7.0.77 777.7.0.777
enable dns
set phone 5551212
# Here is an accurate description of the usr
set authname doofus
set authkey silly_bugger

I get errors from route that the network is unreachable, however, this
seems reasonable as we are not connected yet. Is this correct???
If I run netstat at this point, it does not list my ISP's nameservers
despite the fact that they are indeed listed in /var/log/ppp.log
So I run the following script:
------------------------------------------------------------------------------
:::::::::::::
/home/doofus/route.sh
:::::::::::::
#!/bin/sh
# ident: route.sh
route add 777.7.0.7 -netmask 255.255.255.0 777.7.7.777
route add 777.7.0.77 -netmask 255.255.255.0 777.7.7.777
# forcing the issue...just to prove I can telnet to something!!!
route add 666.66.0.666 -netmask 255.255.255.0 777.7.0.777
------------------------------------------------------------------------------
Now route complains that it already knows about the nameservers...
Then I run ifconfig and all looks OK...
------------------------------------------------------------------------------
:::::::::::::
ifconfig -a
:::::::::::::
xl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500

------------------------------------------------------------------------------
I run netstat and it sees the gw and ns1 and ns2.

netstat -rn

But telnet dies --- "No route to host" even tho it finds the IP of the
box in question. ???
Thanks!
