hello list, Our setup:
- a MAN network with thousand of Mac computers running Mac OS X 10.4, 10.5 and 10.6 - two linux servers running dhcp-3.1.3ESV and bind-9.5.0P2, redundant as a cooperation, this is the main DHCP/DNS servers for the MAN - a multitude of servers running Mac OS X Server (10.4, 10.5, 10.6) for our clients, not centralized, connected to the MAN - 13 DNS zones - HSRP network by Cisco with circa 20 loop of a 23-bit range address (ex. : 10.29.32.1/23, 10.29.36.1/23, 10.29.52.1/23, .../23), that is the MAN Each clients computers are connected to the centralized DHCP/DNS Linux server's and are registered in the zone with the DynamicDNS function. We use the DHCP Client ID (option 61) of the service to redirect and register the client computer into the good domain The linux servers are in the main domain city.educational, at the first level, it's IP addresses is 10.28.25.50 and 10.28.25.51 All others zones are in the form: department.city.educational All clients machines are in DHCP. Servers are in DHCP with a statically assigned address The problem: On 10.5 computers, all are still okay, you can found all records using the host command and ping them: $ hostname 002378.department.city.educational $ host 002378 002378.department.city.educational has address 10.29.76.13 $ host 10.29.76.13 13.76.29.10.in-addr.arpa domain name pointer 002378.department.city.educational. $ ping -c3 002378 PING 002378.department.city.educational (10.29.76.13): 56 data bytes 64 bytes from 10.29.76.13: icmp_seq=0 ttl=64 time=0.547 ms 64 bytes from 10.29.76.13: icmp_seq=1 ttl=64 time=0.512 ms 64 bytes from 10.29.76.13: icmp_seq=2 ttl=64 time=0.482 ms --- 002378.department.city.educational ping statistics --- 3 packets transmitted, 3 packets received, 0% packet loss round-trip min/avg/max/stddev = 0.482/0.514/0.547/0.027 ms $ cat /etc/resolv.conf domain department.city.educational search department.city.educational city.educational department.city.educational nameserver 10.28.25.50 nameserver 10.28.25.51 on 10.6 computers, you can host but the ping does not work $ host 002378 002378.department.city.educational has address 10.29.76.13 $ ping 002378 ping: cannot resolve 002378: Unknown host This mean that you can not resolve 002378 without his FQDN Graphically example is the "Connect to Server" window form the Finder with the short name of the server resulting in a failed connection. On a 10.6, a printer like 500265 (FQDN = 500265.department.city.educational) does not print if you not utilize the FQDN. On 10.4 and 10.5 all this work If you setup your 10.6 clients statically with the DNS, example with the following command line: networksetup -setsearchdomains Ethernet department.city.educational city.educational the problem disappaers and all is okay If you read the /etc/resolv.conf from a 10.4, 10.5 or 10.6 clients, all lines are the same ! in DHCP setup or statically setup, on a linux box is the same result ! I think Mac OS X 10.6 not interpret correctly the domain search from a DHCP server because all others systems work well Please let me know if anyone in the list have the same problem or a workaround Help are welcome Thank you for reading Banana _______________________________________________ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
