Hi!
There is gdb's output:
0x280d7ea4 in _poll ()

There is a part of my config file. There IS "delete! default":
default:
delete! default
set log Phase Chat LCP IPCP CCP tun command +debug
set device /dev/modem
set speed 57600
set reconnect 1 50
set timeout 300
set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \"\" AT OK-AT-OK
ATE0Q0S0=1
pmdemand:
delete! default
set phone 777777
set login "TIMEOUT 120 ogin:--ogin: cbdv word: XXXX string: YYYYY
CONNECT
set log +debug
set timeout 300
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
There is netstat -rn:
home# netstat -rn
Routing tables
Internet:
Destination Gateway Flags Refs Use Netif
Expire
default 10.0.0.2 UGSc 0 0 tun0
127.0.0.1 127.0.0.1 UH 0 33 lo0
When I delete default, ppp works OK:
home# ppp -auto pmdemand
Working in auto mode
^C
home# route delete default
delete net default
home# ppp -auto pmdemand
Working in auto mode
Using interface: tun0
home#
Is it enought to make you sure that it isn't user error? :)
You can reprodyce the problem by:
1. uncommenting 'pmdemand' section and add there delete! default
2. starting ppp with 'ppp -auto pmdemand'
3. killing it with -9
4. starting it again

Are you doing anything funny with ``hostname'' on your machine ?
The only reports I've heard where ppp hangs at startup is when your
``hostname'' won't resolve (see http://www.FreeBSD.org/FAQ/userppp.html).
If this isn't the problem, I'd appreciate if you could build ppp with
-g and when it hangs, run ``gdb -p whatever'' and do a ``bt''.
Cheers.
