[opensuse] how to block IP's with /etc/hosts.deny? (not working)
Hi all, I am having some trouble with one IP, that is bugging one of my servers for almost a week now with virusses. I have been putting this IP in /etc/hosts.deny, but it is not blocked when connecting to postfix. Why is this? Is it not possible to block traffic to port 25 this way? -- L. de Braal BraHa Systems NL - Terneuzen T +31 115 649333 F +31 115 649444 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

To answer my own question (or better how I solved the problem): I found out I can block it by putting the IP in /etc/postfix/access, this works.

Look TCP wrappers info : "A TCP wrapped service is one that has been compiled against the libwrap.a library" Maybe, you can use xinetd Anyway, you always can block incoming traffic with netfilter (iptables) 2009/6/3 Leen de Braal <ldb@braha.nl>:

Within hosts.deny how do you have your line define? I use it to block people trying to ssh to my by adding a line like this... sshd: xxx.xxx.xxx.xxx You may have to do smtpd: xxxxxx.xxx.xxx I know you are using postfix and found the access file to me that is the best pratice to allow and deny access postfix.
