Accepted AnswerWhere does dnsmasq keeps it's list of dynamic/static clients ?
Does it have any other config file?
I ssh into the box and manually stop the service, with ./etc/init.d/dnsmasq stop.
that seems to work., I reboot the box, and dhcp was still off, ok.
Now I enable dhcp for eth3 again, and gest what? yes ? it is finding the tftp server and boot file with out me tell it where to look or what file name to ask for !!!!!
all I can do now it uninstall dnsmasq 2.72 or just kill the server and re-do it from
Anyway any help will be welcome.

If what you need is in 2.72, you should be able to get it there.
FWIW, that rpm is being heavily tested right now due to a dependency in upcoming apps. Should be pretty stable.
I did just this, but I have a major problem.
I have now disable dhcp on my eth3 in webcofig, that's the only one that had dhcp enable.
but my workstation is still getting dhcp from this box. WHY?
I also remove any --dhcp-option=* from /etc/dnsmasq.d/dhcp.conf
I also remove the dhcp-boot=* option from the /etc/dnsmasq.conf file. but my network boot is still getting dhcp & tftp info. WHY?
Accepted Answerdo you know the syntax in 2.7.2 for :
dhcp-boot= 'as pertain to interface
dhcp-option= 'as pertain to 66 & 67, with interface
I still can't believe that
option work, but the
did not work.
I don't thing dhcp-helper is neede any more, because 2.72 support
but I can't make a rpm from it.
Accepted AnswerDNSMasq does not have any native DHCP relay features. However, a major writer of DNSMasq has written dhcp-relay which is a very light weight DHCP relay worker. We don't have a package for this yet and you would have to install this via building it on your server. BIND is an alternative but it also does DHCP and DNS and will collide with DNSMasq so you'd have to turn off DNSMasq to use the ISC BIND package.
Accepted Answerno you are not the only one!
I am using 6.5.0 how do I enable dhcp relay ?
setting up Citrix PVS and need this feature
-eth0 -external (internet)
-eth1 -lan (dns,dhcp,AD,files,sql,mail,wsus,ca,printsrv,web) 192.168.100.0/24 (vlan10)
-eth2 -lan (eqxDB,eqxApp,eqxAdmin) 192.168.101.0/24 (vlan20)
-eth3 -lan (xenLic,xenDDC,xenSF,xenAPP,xenPVS,xenvdi-##) 192.168.102.0/24 (vlan30)
how can I setup dnsmasq to dhcp-relay from eth3 to 192.168.100.3 (AD-Domain-Controller) ?
Accepted AnswerThe router is routing several different subnets and I want a single DHCP server that exists on only one of the subnets. The router needs to forward the DHCP packets to the proper server when it sees them come in. On other linux distributions this is typically available in a package called dhcrelay, but I don't see this package available in the clearos repository.
