 Posted: Tue Apr 13, 2004 1:43 am Post subject: Routing after rebooting |
 |
|
Thanx to the search function and many topics related to this, I've managed to setup a working router...
I've emerged dhcp and iptables, and added iptabled and dhcp with rc-update to default so they will start at boot. Iptables works fine, but dhcp just gives [!!] while booting, and I have to run the command dhcpd again after I have logged in.
Another problem is the ip forwarding. Everytime the system boots I have to log in and run the command
| Code: | | # echo 1 > /proc/sys/net/ipv4/ip_forward |
Anybody knows howto automatically start dhcpd and set ip_forward standard to 1? |

There is a setting in /etc/sysctl.conf that you can change that might fix your ip forwarding issue. Just uncomment it and set it to 1.
I don't know anything about the rest of your problem. Sorry. |

To fix your forwarding problem try:
| Code: | | nano -w /etc/conf.d/iptables |
then set the
ENABLE_FORWARDING_IPv4="yes"
Regarding your DHCP problem, i think its just an error in your config, thats causing the failure, check that again and try examining the logs.
My dhcpd.conf look something like this:
| Code: |
subnet 192.168.1.0 netmask 255.255.255.0
{
option broadcast-address 192.168.1.255;
deny bootp;
option domain-name "mydomain.com";
option domain-name-servers 192.168.1.254;
default-lease-time 172800;
max-lease-time 345600;
option netbios-dd-server 192.168.1.254;
option netbios-name-servers 192.168.1.254;
option netbios-node-type 8;
option subnet-mask 255.255.255.0;
range 192.168.1.101 192.168.1.150;
option routers 192.168.1.254;
}
host eden.mydomain.com {
hardware ethernet 00:01:02:36:01:64;
fixed-address 192.168.1.151;
}
|
Please note that the internal IP address of your DHCPd server should not
be included in the range option. In my case the
DHCPd server has the 192.168.1.254 IP and the
range 192.168.1.101 192.168.1.150;
HTH
BTW, i found your post because of this thread:

Okey, I've changed /etc/conf.d/iptables, and for as far as I know my dhcpd.conf is correct?
My dhcpd.conf:
| Code: | # dhcpd.conf
option domain-name "home.nl";
default-lease-time 600;
max-lease-time 7200;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.0.255;
option routers 192.168.0.1;
option domain-name-servers 213.51.129.170, 213.51.144.170;
ddns-update-style interim;
ignore client-updates;
subnet 192.168.0.0 netmask 255.255.255.0{
range 192.168.0.2 192.168.0.254;
option broadcast-address 192.168.0.255; |

Are you sure you did not miss the closing "}" while copy pasting?

I emerge'd dhcp on my gentoo box today just to check.
I used your dhcpd.conf (with the closing "}") just to check and it won't run too.

Obviusly your [fixed]dhcpd.conf is not the problem.
It's /var/lib/dhcp/dhcpd.leases.
I fixed it by:
| Code: | | gen2h dhcp # touch /var/lib/dhcp/dhcpd.leases |
then..
| Code: | | gen2h dhcp # chown dhcp.dhcp /var/lib/dhcp/dhcpd.leases |
then tried again..
| Code: | gen2h dhcp # /usr/sbin/dhcpd eth0 -d
