hi i am memeber of linux,org

i am a linux user but i am facing a problem to setup a dhcp server on fedora for a vlan setup with layer 3 switch

my vlan 10 shuld be 192.168.10.x series ip
vlan 20 shuld be 192.168.20.x

vlan30 shuld be 192.168.30.x

its so easy with windows creating scopes but in linux , the service fails when i enter subnet

ddns-update-style interim;
dynamic-bootp-lease-length 86400;
max-lease-time 604800;
default-lease-time 604800;

subnet 192.168.10.0 netmask 255.255.255.0 {
option routers 192.168.10.1;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.10.255;
option nis-domain "xyz.net";
option domain-name "xyz.net";
option domain-name-servers 192.168.10.2;
option time-offset -18000;
authoritative;
option ntp-servers 192.168.10.2;
option netbios-name-servers 192.168.10.2;
option netbios-node-type 2;
range 192.168.10.50 192.168.10.220;
}

it works and when i try to create other subnets or scopes below ,, it fails to restart , i checked /var/log/messages ,, its says dhcp exited multiple subnet not supported i am using fedora 7

plz help me with this problem , is linux not a good opeating system for dhcp server , when compared to windows2003

i am fan of linux but this is dissapointing me now ,

thanks in advance , try to suggest some solution

you're configuring isc dhcp, which is *VASTLY* more common globally than windows based dns services, not even nearly a comparison. also note this has nothing to do with linux, but software which runs on just about ALL unix variants and windows to boot.... it's not fair to assume this is linux's fault, esp if you may have made a mistake, which you have.

So, your config is clearly wrong. the broadcast address for 192.168.20.0/24 is listed as 192.168.10.255, which doesn't make sense.

This may help;

if its wrong ,, i need correct example of dhcp.conf and settings
just saying wrong would not help me , i request u sir to provide me a sample which works for vlan clients to get ip address from my server

the site links only describe about single network , that is 192.168.0.x , with c class subnet 255.255.255.0

thats only single subnet , i know that how to use it

i need multiple scopes of different subnet

192.168.0.x , 192.168.1.x , 192.168.3.x with all subnet as 255.255.255.0 for all machines


can some one plz help me out , in linux , i am not able to understand how to make this server work for vlan

in microsoft win 2003 its so easy , just creating scopes ,, works but in linux it never works why ?

i've told what what *i* can see is immediately wrong, you just haven't read it...
