Hallo ! I habe schon länger Suse 7.2 auf meinem Server installiert. Dann habe ich tcpd für sshd in der inetd konfiguriert. Heute habe ich "bind" mit einem RPM für Suse 7.2. Ich habe die Konfig belassen wie sie im RPM war. Aber TCPD macht KEIN reverse lookup von IP Adressen 1) Wenn ich folgende eingebe um die Funtion des reverse lookup zu prüfen: root@fire-linux:/home/awuerfli > tcpdmatch sshd localhost warning: host address ::ffff:127.0.0.1->name lookup failed client: address ::ffff:127.0.0.1 server: process sshd matched: /etc/hosts.allow line 9 access: granted client: hostname localhost client: address ::1 server: process sshd matched: /etc/hosts.allow line 9 access: granted warning: host address 7f00:1:6c6f:6361:6c68:6f73:7400:0->name lookup failed client: address 7f00:1:6c6f:6361:6c68:6f73:7400:0 server: process sshd matched: /etc/hosts.deny line 1 access: denied root@fire-linux:/home/awuerfli > 2) Aber dann dürfte doch "nslookup" nicht funktionieren, oder ? root@fire-linux:/home/awuerfli > nslookup Default Server: localhost Address: 127.0.0.1

127.0.0.1 Server: localhost Address: 127.0.0.1

Name: localhost Address: 127.0.0.1 3) Dasselbe geht auch mit einer anderen IP Adresse (example: 62.99.189.10)

62.99.189.10 Server: localhost Address: 127.0.0.1

Name: static62-99-188-10.adsl.inode.at Address: 62.99.189.10 So - warum geht "tcpdmatch" und damit tcpd nicht ??
