Thanks. In the dump we can see that connections reusing ports
always have their first SYN dropped and retransmissted three
seconds later. I'm not sure whats causing this yet, do you have
any firewall rules that affect loopback traffic?
No firewall.
And the "lp" is just to print to a [EMAIL PROTECTED]
# lpadmin -p lp -i /etc/cups/interfaces/lp -v lpd://localhost/file -o
printer-error-policy=retry-job
# lpadmin -p file -i /etc/cups/interfaces/file -v file:/dev/null -o
printer-error-policy=retry-job
Filter for lp is ..
cat $6
Filter for file is ...
cat $6 >/tmp/$$
Actually its probably the SYN/ACK that is dropped. Please try whether
modprobe ipt_LOG
echo 255 >/proc/sys/net/netfilter/nf_conntrack_log_invalid
and then running the test again logs something to the ring buffer.
You don't need to run the entire test, just until you get a log
message from conntrack.
