hello list. i seem to have a recurring problem with the ip_conntrack_ftp-module. it was not loaded by default, so i've put a line into the iptables-script , which does a : modeprobe ip_conntrack_ftp it should then track all incoming ftp-connections, ports source/destination high above 1024. but at all, it does not work. the lsmod says : ip_conntrack_ftp 4000 0 (unused) ip_conntrack 19724 2 [ip_conntrack_ftp ipt_state] ftp-users can login, but get no data-connection :( the basic question is : where is the dokumentation ? :)) do i have to activate the module with different switches than the iptables -m switches ? thx.gerhard -----Ursprüngliche Nachricht----- Von: Vladimír Dvorak [mailto:dvorakv@suse.cz] Gesendet: Donnerstag, 5.

Hello List,
I still have problem with my Postfix installation. I can send/receive mail locally but remote users can not. With "telnet localhost 25" i can write mail, but "telnet 1.2.3.4 25" says "Connection refused". SMTPD_LISTEN_REMOTE = yes. What could be the problem?
TIA istvan
netstat -ltn | grep 25 You probably see: tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN But there should be for all incoming traffic: tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN See in /etc/postfix/main.cf if there is inet_interfaces = all --vlada -- Best Regards, Vladimir Dvorak, Internal IT --------------------------------------------------------------------- SuSE CR, s.r.o. e-mail: vlada@suse.cz Drahobejlova 27 tel:+420 2 96 542 373 190 00 Praha 9 fax:+420 2 8309 5374 Czech Republic http://www.suse.cz -- Check the headers for your unsubscription address For additional commands, e-mail: suse-security-help@suse.com Security-related bug reports go to security@suse.de, not here
