OpenSuse 11 DHCP Server

English Network/Internet
#1

hi all

ive been using opensuse since 10.x
and it really served my needs

i just wana as if Opensuse 11 is capable of being a MULTISCOPE Dhcp Server , i tried it as a single scope dhcp server a long time ago , it worked like a charm…im planning to make it as a backup dhcp of our network

thanks all in advance

#2

What is a multiscope server? More than one interface? For sure. It’s ISC DHCPD.

#3

a DHCP server serving around 5 VLANS

192.168.20.x
192.168.24.x

subnets sirs

Should be no problem. See the ISC DHCPD doco. You probably have to configure with a text editor, I don’t think YaST caters for such a complex use case.

backup dhcp? Well anyhow… yes… it supports multiscope and VLAN
combo ranges, bootp, failover and a TON of features.

#6

is this the YAST DHCP config or the isc dhcp…?

thanks for all the replies keep it coming

more power

#7

YaST is only a frontend to the ISC DHCP config files and it won’t do complex stuff.

#8

so in my case ill have to do this manually on the CLI or kwrite?

sirs?

#9

So sad, but yes.

#10

oki…trying this out…

#11

Create a shared-network def in dhcpd.conf and
place the subnet declarations inside.

hi all

i change the title coz i think its a little bit confusing

heres what i want to do and my scenario

we are on a VLAN Network my issue is on the dhcpd.conf side coz wana configure My opensuse 11 box to serve ip’s (DHCP Server) on diffrent VLAN , Wana Replace our Windows DHCP Server for some Technical Reasons , my susebux has only one phsysical Network interface (eth0), is this possible to serve all VLAN? iphelper is already confgured on our L3 Switches , actually OUr Windows DHCP Server is already runnning and serving this vlans , but i just wana replace it with linux

is this a dhcpd issue to vconfig?

heres is our VLAN Scheme

Dept.1

VLAN # xx
Range : 192.168.24.xxx-xxx

Dept.2
VLAN # xx
Range : 192.168.24.xxx – xxx

Dept.3
VLAN # xx
Range : 192.168.24.xxx-xxx

Dept.4
VLAN #xx
Range : 192.168.24.xxx-xxx

Dept. 5
VLAN # xx
Range 192.168.20.xxx.xxx

#20

here is my dhcpd.conf

-----------VLAN 201--------------#

subnet 192.168.20.0 netmask 255.255.255.0{
range 192.168.20.150 192.168.20.254;
option routers 192.168.20.129;
option subnet-mask 255.255.255.0;
#option broadcast-address 172.27.0.255;
option domain-name-servers 192.168.20.11;
}

----------- -VLAN 243 -------------#

subnet 192.168.24.0 netmask 255.255.255.0{
range 192.168.24.226 192.168.24.230;
option routers 172.27.1.1;

#option broadcast-address 172.27.1.255;
option domain-name-servers 192.168.20.11;
}
