Hi,
I'm runninng diald v.0.98-1 and I'm having a problem with (presumably)
netbios
packets that keep bringing the link up. Iptraf shows udp/netbios-ns and
udp/netbios-dgm packets that seem to throw the link up. I've got the
following
lines in standard.filter:
--- COPY ---
# Don't bring the link up for rwho.
ignore udp udp.dest=udp.who
ignore udp udp.source=udp.who
# Don't bring the link up for RIP.
ignore udp udp.dest=udp.route
ignore udp udp.source=udp.route
# Don't bring the link up for NTP or timed.
ignore udp udp.dest=udp.ntp
ignore udp udp.source=udp.ntp
ignore udp udp.dest=udp.timed
ignore udp udp.source=udp.timed
# Don't bring up on domain name requests between two running nameds.
ignore udp udp.dest=udp.domain,udp.source=udp.domain
# Bring up the network whenever we make a domain request from someplace
# other than named.
accept udp 30 udp.dest=udp.domain
accept udp 30 udp.source=udp.domain
# Do the same for netbios-ns broadcasts
# NOTE: your /etc/services file may not define the netbios-ns service
# in which case you should comment out the next three lines.
ignore udp udp.source=udp.netbios-ns
ignore udp udp.dest=udp.netbios-ns
ignore udp udp.source=udp.netbios-dgm
ignore udp udp.dest=udp.netbios-dgm
accept udp 30 udp.dest=udp.netbios-ns
accept udp 30 udp.source=udp.netbios-ns
# keep routed and gated transfers from holding the link up
ignore udp tcp.dest=udp.route
ignore udp tcp.source=udp.route
# Anything else gest 2 minutes.
accept udp 300 any
# Catch any packets that we didn't catch above and give the connection
# 30 seconds of live time.
accept any 30 any
--- CUT---
As you see I'm ignoring nearly all of the udp packets that in my view
are brining
the link up, and are just packets windows seems to the network for fun.
Here's
a line from my /var/log/messages:
Mar 4 15:24:15 neutron diald[4724]: Trigger: udp
195.170.128.4/53 195.170.129.129/62788
195.170.128.4/53 seems to point to my ISP's nameserver and port 53 to
a domain-request? Now, if I disable udp/domain the link won't be
triggerd at all,
if I start Communicator or IE on a client. Has anyone ideas?
