There have been changes in the netselect code, maybe your firewall is
dropping the traffic. If you log the dropped traffic on the iptables
firewall, could you please look into your 'dmesg' output to see if you have
discarded traffic?
In order to fully debug this issue I would need you, if you agree, to run the
following (as root):
--------------------------------------------------------------------------
script /tmp/test_netselect.log
iptables -vnL
tcpdump -w /tmp/test_netselect.cap -s 0 -c 10000 icmp &
--->[ Please write down the process number that is shown here ]
netselect -I -vv ftp.debian.org ftp.de.debian.org
ping -c 5 ftp.debian.org
ping -c 5 ftp.de.debian.org
iptables -vnL
killall -i tcpdump
--->[ When asked, only kill the process number that matches the one
shown before ]
exit
--------------------------------------------------------------------------
What this does is: write all the output of the commands to a log file, print
out the iptables ruleset with counters, run a packet capture, then run the
tests I told you in my previous message, print out the iptables ruleset (to
see where did the packets sent match) and then kill the packet capture
process.
When finished, send me both the /tmp/test_netselect.log file as well as the
PCAP capture /tmp/test_netselect.cap. Please don't sent it to the bug report,
do it privately, as some of the information might be sensitive and the
information in bug reports are all publicly available
