RE: Ethernet Stopping Problem



Hi Danial,

Any ideas as to how I would be able to find out more if it was an arp
problem. I don't see how it could be because I have only 3 machines on the
network at the time that it died. The three where the router, the freebsd
gateway, and my notebook. Is there something I could enable on the sysctl
side of things? Or syslogd side of things to try and see if it is an arp
problem, and if it is, how can I rectify it ?

Cheers
Ian

Things that stop after 5-10 minutes are usually
ARP related, but I can't be certain.

Explain where you are getting the public
non-routable 10.0.0.0 ip
address from.
You say the ADSL router is using them.
Did you edit your real ip address to hide then
from this public
post?
Also you have to post your ppp.conf file.
Are you trying to configure PPPoe?

Hi,

I have a freebsd 5.2 box setup as my gateway
for my home network.
The
network is layed out as follows:

FreeBSD Gateway - 10.0.0.1/16
ADSL Router - 10.0.0.2/16

DHCP Network - 10.0.1.0 - 10.0.1.254 all /16
with default gateway as
.1

I have ppp enabled on the freebsd unit, and it
connects fine and
then
everything works perfectly for anything between
5 and 10 minutes. At
this
stage, the freebsd machine cant get to the
10.0.1.0 network anymore.
It can
still ping 10.0.0.2 fine and its connection to
the internet remains
perfect.
It just wont let anyone else come in from
anywhere else on the
network. It
kills all SSH sessions, web sessions etc. I
replaced the ifac card
with an
ed0 card, and also replaced cables and the
switch in between.

The card in question is both a dc0 and an ed0
card which I have
swapped into
another PCI port and it still does the same
thing there. Below is an
ifconfig:

ed0:

flags=108843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST>
mtu 1500
inet 10.0.0.1 netmask 0xffff0000
broadcast 10.0.255.255
ether 00:c0:df:fa:b8:74
plip0:
flags=108810<POINTOPOINT,SIMPLEX,MULTICAST> mtu
1500
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST>
mtu 16384
inet 127.0.0.1 netmask 0xff000000
tun0:
flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST>
mtu 1492
inet 165.x.x.x --> 165.x.x.x netmask
0xffffffff
Opened by PID 218
[root@gateway] ~ #


Here is a rc.conf:
[root@gateway] ~ # cat /etc/rc.conf
defaultrouter="10.0.0.2"
hostname="gateway.domain.local"
ifconfig_ed0="inet 10.0.0.1 netmask
255.255.0.0"
saver="logo"
sshd_enable="NO"
usbd_enable="YES"
blanktime="3600"
apache2_enable="YES"
mysql_enable="YES"
sendmail_enable="NONE"
gateway_enable="YES"
inetd_enable="NO"
kern_securelevel_enable="NO"
ppp_enable="YES"
ppp_nat="YES"
ppp_mode="ddial"
ppp_profile="dsl1"
dhcpd_enable="YES"
dhcpd_flags="-q"
dhcpd_conf="/usr/local/etc/dhcpd.conf"
dhcpd_ifaces="ed0"
[root@gateway] ~ #


I don't have any sysctl rules in place, and
everything else about
this unit
is standard.

I am not running a firewall at this stage and
was just wondering
what the
cause of this problem could be?

Cheers
Ian
