I have a test CentOS 4.4 workstation that I am trying to configure to use vendor options from a W2003 DHCP server.
A vendor class with the custom options has been created on the windoze box and I seem to be receiving the info in the vendor-encapsulated-options shown in the lease file. What I don't know is how to decode these options so that the CentOS client uses them. I have searched the web and read the man pages and come up with a configuration for the /etc/dhclient.conf but as yet I am unable to get the extra options to work and to be honest I don't fully understand how the dhclient.conf should be written.
Can anyone shed some light on what I am doing wrong or missing.
/var/lib/dhcp/dhclient-eth0.leases
lease { interface "eth0"; fixed-address 192.168.80.10; option subnet-mask 255.255.255.0; option dhcp-lease-time 691200; option dhcp-message-type 5; option dhcp-server-identifier 192.168.80.1; option dhcp-renewal-time 345600; option dhcp-rebinding-time 604800; option vendor-encapsulated-options 28:a:70:75:62:6c:69:63:6e:65:74:0:29:8:c1:76:c0:21:c1:76:c0:18:2a:8:c1:7 6:c0:18:c1:76:c5:5e:77:1e:63:6f:6d:6d:2e:61:64:2e:72:6f:6b:65:2e:63:6f:2 e:75:6b:20:72:6f:6b:65:2e:63:6f:2e:75:6b:0; renew 1 2006/9/25 12:41:13; rebind 5 2006/9/29 10:32:59; expire 6 2006/9/30 10:32:59; }
/etc/dhclient-eth0.conf
send host-name "test"; send vendor-class-identifier "CentOS"; vendor option space "CentOS"; request CentOS.nis-domain; request CentOS.nis-servers; request CentOS.ntp-servers; request CentOS.domain-search-list;
Thanks
