Hi, I wanna configure dhcpd and named in chroot jail for security reason. Dhcpd and named work well but dhcpd does not update named and in the log files i have nothing that help me to understand the problem. I use suse professional 9.1. I read the document in /usr/share/doc/packages/bind but i do not know where is the problem. Could you help me ? Best regards, Cristian Del Carlo. My configuration is the following : 1) /etc/dhcpd.conf default-lease-time 600; max-lease-time 7200; include "/etc/named.keys"; authoritative; allow unknown-clients; ddns-update-style interim; ignore client-updates; subnet 10.1.1.0 netmask 255.255.255.0 { range 10.1.1.101 10.1.1.185; option domain-name "test.it"; option domain-name-servers 10.1.1.1; option subnet-mask 255.255.255.0; option routers 10.1.1.1; option domain-name-servers 10.1.1.1; ddns-domainname "test.it"; ddns-rev-domainname "1.1.10.in-addr.arpa"; zone test.it. { primary 127.0.0.1; key DHCP_UPDATER; } zone 1.1.10.in-addr.arpa. { primary 127.0.0.1; key DHCP_UPDATER; } } 2) /etc/named.conf acl PROVIDER { 192.168.9.30; }; acl BIND { 10.1.1.1; 127.0.0.1/8; }; acl RETELOCALE { 10.1.1.0/24; 127.0.0.1/8; }; options { directory "/var/lib/named"; dump-file "/var/log/named_dump.db"; statistics-file "/var/log/named.stats"; forwarders { 192.168.9.30; }; listen-on port 53 { BIND; }; listen-on-v6 { any; }; allow-query { RETELOCALE; }; allow-transfer { none; }; allow-recursion { RETELOCALE; }; notify no; }; < .......> include "/etc/named.conf.include"; include "/etc/named.keys"; zone "test.it" in { type master; file "test.it/master.zone"; allow-transfer { 127.0.0.0/8; }; allow-update { key DHCP_UPDATER; }; }; zone "1.1.10.in-addr.arpa" in { type master; file "test.it/10.1.1.0.zone"; allow-transfer { 127.0.0.0/8; }; allow-update { key DHCP_UPDATER; }; }; 3) /etc/named.keys key DHCP_UPDATER { algorithm hmac-md5; secret "<samething>"; }; 4) /etc/sysconfig/named NAMED_RUN_CHROOTED="yes" NAMED_CONF_INCLUDE_FILES="rndc-access.conf /etc/named.keys" NAMED_ARGS="" 5) /etc/sysconfig/dhcpd DHCPD_INTERFACE="eth0" DHCPD_RUN_CHROOTED="yes" DHCPD_CONF_INCLUDE_FILES="/etc/named.keys" DHCPD_RUN_AS="dhcpd" DHCPD_OTHER_ARGS="" DHCPD_BINARY="" 6) ls -al /var/lib/named drwxr-xr-x 10 root root 4096 Sep 23 14:02 . drwxr-xr-x 58 root root 4096 Sep 28 08:34 .. -rw-r--r-- 1 root root 192 Apr 6 04:06 127.0.0.zone drwxr-xr-x 2 root root 4096 Sep 28 08:27 dev drwxr-xr-x 2 named named 4096 Apr 6 04:06 dyn drwxr-xr-x 3 root root 4096 Sep 28 14:55 etc -rw-r--r-- 1 root root 158 Apr 6 04:06 localhost.zone drwxr-xr-x 2 named named 4096 Sep 24 12:07 log drwxr-xr-x 2 root root 4096 Sep 23 14:02 master -rw-r--r-- 1 root root 2517 Apr 6 04:06 root.hint drwxr-xr-x 2 named named 4096 Sep 23 12:11 slave drwxr-xr-x 2 named named 4096 Sep 28 18:54 test.it drwxr-xr-x 4 root root 4096 Sep 23 09:31 var
