dnsmasq in openvz slackware VE
Hi,
i'm in trouble with running dnsmasq as dhcp server in an openvz ve under slackware 14.0. DNS runs fine, dhcp doesn't work. No packet filters running, it shows the following behaviour:
In VE, ps ax and /var/log/messages show the following:
Code:
root@dns_dhcp:~> cat /etc/dnsmasq.conf
user=vmdnsmasq
group=vmdnsmasq
interface=venet0
#dhcp-authoritative
dhcp-range=192.168.0.190,192.168.0.200,96h
root@dns_dhcp:~> ps ax

...looks good for me, or is there anything wrong? If it's important: the IP range of the leases does not intersect with the IP addresses in /etc/hosts.
Now try to get an address by a client (physically a different machine):
Code:
root@multivac:~> dhclient eth0
root@multivac:~>
let's have a look at /var/log/messages:
Code:
root@multivac:~> cat /var/log/messages
<SNIP/>
Jan 21 14:22:14 multivac kernel: [16949.417422] ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
Jan 21 14:22:18 multivac dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 15

Jan 21 14:23:11 multivac dhclient: No DHCPOFFERS received.

Having a closer look with nmap to the VE running dnsmasq:
Code:
root@multivac:~> nmap 192.168.0.2
Starting Nmap 6.01 ( http://nmap.org ) at 2013-01-21 14:28 CET
Nmap scan report for dns_dhcp (192.168.0.2)
Host is up (0.00024s latency).
Not shown: 998 closed ports
PORT STATE SERVICE
22/tcp open ssh
53/tcp open domain
MAC Address: xx:xx:xx:xx:xx:xx (Netronix)
Nmap done: 1 IP address (1 host up) scanned in 0.79 seconds
Shouldn't port 67 be open?
I get the same result from other machines that try to get a lease.
Has anyone an idea or a hint?
confused
