I sync'd up with stable a couple of days ago and
I am having problems with ppp (used with -auto). If the IP address is not
explicitly specified in ppp.conf, then outgoing packets get sent with a source
address of 0.0.0.0, even though the inteface appears to be configured correctly:
bash# tcpdump -n -i tun0
tcpdump: listening on tun0
23:40:00.184347 0.0.0.0.53 > 128.9.0.107.53: 58951 A? internic.net. (30)
23:40:01.194388 0.0.0.0.53 > 192.33.4.12.53: 58948 A? internic.net. (30)
^C
bash# ifconfig tun0
tun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1500
inet 131.252.218.8 --> 204.203.69.20 netmask 0xffff0000
The relevant bits of /etc/ppp/ppp.conf are as follows:
default:
set device /dev/cuaa1
set speed 57600
disable lqr
deny lqr
set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \"\" AT OK-AT-OK \\dATDT\\T TIMEOUT 40 CONNECT"
set ctsrts on
server:
set ifaddr 0 204.203.69.20
add default HISADDR
I probably should be including something else, but I don't recall what....
I have tried using both the 2.2.6-BETA kernel and an earlier (January-ish)
kernel that I had installed before the upgrade, but that didn't help (thereby
suggesting the bug is not a recent addition to the kernel). I tried cvsupping
and rebuilding ppp, but that didn't help. I tried talking to a PPP server
where my IP address is statically assigned, so I could set my own ifaddr, and
that *did* help.
Useful comments appreciated. I might try throwing away the ppp and/or netinet
sources and rebuilding, but I do not have the network bandwidth to do that
available at the moment -- something about PPP problems.... (-:
