Dear all,
I'm using buc for a while and have done a new setup of buc v3.1 few weeks ago.
Since them, I observe very long delay when connecting on SMTP from LAN to the
Internet. Waiting about 10 sec for opening SMTP (25).
Furthermore I observed:
1) All other TCP services ports are working normaly.
2) IPTRAF on the firewall shows NEW connexion from LAN to FW and
from FW to target SMTP server about 10 sec after having sent the message.
3) In the mean time, no particular traffic happens on IPTRAF screen except DNS
traffic.
4) This is not a Auth missbehaviour (rejected with nodelay insteed of droped).
5) Connecting my workstation directly to the modem allow normal SMTP traffic.
In that case, modem allow all outgoing traffic.
6) My WS is permanently firewalled by shorewall, allowing only few outgoing
traffic.
7) I'm using following buc packages:
LRP="root config etc local modules iptables libcrpto libm libz mawk
shorwall ulogd dropbear ntpdate ntpsimpl dhcpd daemontl djbutils
dnscache tinydns"
My questions:
Q1) Do anybody have made some analog experiments or
have any idee about such a behaviour ?
Q2) How may I refine diagnostic in order to get more acuracy in
problem description ?
Many thanks in advance for your hand
Kindest regards
bib
