[Dnsmasq-discuss] dnsmasq: failed to create listening socket: Address already in use
Hello, The OS is Scientific Linux 6.3 (which is similar to redhat, centos and fedora) and I have installed dnsmasq with the following configuration | interface=eth1 domain=hpclab expand-hosts dhcp-range=10.0.2.51,10.0.2.100,static dhcp-option=42,0.0.0.0 dhcp-boot=pxelinux.0 enable-tftp tftp-root=/var/lib/tftpboot dhcp-host=08:00:27:69:73:7A,ws04,10.0.2.51 | and current node (which runs dnsmasq) has this ip | eth1 Link encap:Ethernet HWaddr 08:00:27:A9:20:C0 inet addr:10.0.2.15 Bcast:10.0.2.255 Mask:255.255.255.0 inet6 addr: fe80::a00:27ff:fea9:20c0/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 | However, I get error when trying to start the dnsmasq service | [root@localhost mahmood]# /etc/init.d/dnsmasq status dnsmasq is stopped [root@localhost mahmood]# /etc/init.d/dnsmasq start Starting dnsmasq: dnsmasq: failed to create listening socket: Address already in use [FAILED] | netstat command shows the following information | [root@localhost mahmood]# netstat -anlp | grep -w LISTEN tcp0 0 0.0.0.0:111 0.0.0.0:* LISTEN 1252/rpcbind tcp0 0 127.0.0.1:631 0.0.0.0:* LISTEN 1445/cupsd tcp0 0 127.0.0.1:250.0.0.0:* LISTEN 1685/master tcp0 0 0.0.0.0:46556 0.0.0.0:* LISTEN 1348/rpc.statd tcp0 0 :::111 :::* LISTEN 1252/rpcbind tcp0 0 :::80 :::* LISTEN 4884/httpd tcp0 0 ::1:631 :::* LISTEN 1445/cupsd tcp0 0 :::51096:::* LISTEN 1348/rpc.statd | What missconfiguration causes such error and how can I fix that? -- Regards, Mahmood ___ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss
