[Dnsmasq-discuss] No space left in packet

Hi,

I'm currently testing replacing ISC dhdpc with dnsmasq. On one of the test
machines I got an error "cannot send DHCP/BOOTP option 43: no space left
in packet". This message repeated endlessly and none of the clients could
get a lease. All other servers worked fine so far. The other servers have
identical configuration, but the clients may have a different PXE BIOS.

What could be the cause of this? Following is the complete config file.
No command line options are used.

==================================
pid-file=/var/run/dnsmasq/dnsmasq.pid
no-poll
dhcp-no-override
domain=domain.local

dhcp-range=net1,172.16.73.1,172.16.73.254,1d
dhcp-range=net2,192.168.1.101,192.168.1.120,1d

dhcp-option=46,1           # netbios node type
#dhcp-option=47             # empty netbios scope
dhcp-option=net1,option:router,172.16.11.254
dhcp-option=net2,option:router,192.168.1.1
dhcp-option=6,172.16.1.1
dhcp-option=net1,1,255.255.0.0
dhcp-option=net2,1,255.255.255.0

dhcp-option=43,09:0f:00:03:0c:4e:65:74:77:6f:72:6b:20:62:6f:6f:74:0a:05:00:4d
:45:4e:55:06:01:02:08:03:00:03:00:47:04:00:03:00:00:43:01:41:ff

dhcp-boot=dummy.0,server043,172.16.1.53
bootp-dynamic

dhcp-lease-max=254
#dhcp-leasefile=/var/lib/misc/dnsmasq.leases
dhcp-authoritative
==================================

The network net2 is not used, there is no second network card in these
servers.
Option 43 is needed to boot some old PXE clients without a special PXE or
mtftp
server. Is there something wrong with the config file?

Thanks,
hjb
