Someone tell me what Im doing wrong here. Ive set a static IP on this box with following config:

nano /etc/network/interfaces

auto eth0
iface eth0 inet static
address 172.18.240.25
netmask 255.255.255.0
gateway 172.18.240.1

Then

service networking restart

Then run

update-rc.d networking defaults

Which generates the following:

update-rc.d: warning: networking start runlevel arguments (2 3 4 5) do not match LSB Default-Start values (none)
update-rc.d: warning: networking stop runlevel arguments (0 1 6) do not match LSB Default-Stop values (0 6)
System start/stop links for /etc/init.d/networking already exist.

Any time I reboot it, it pulls a new DHCP address until I restart networking again.

can you post the DHCP address generated?

Your network has multiple subnets?

I think it's telling you that your configuration does not meet the "Linux Standard Base." (If so, that's a rather cumbersome way of saying "syntax error.")

You don't mention what distro/version you are using, which is useful information because there can differences among how different distros do things. I can share my static ip configuration from my Debian system.

You might also check your router configuration. Most routers allow you to identify a pool of addresses for DHCP. The last one I installed started DHCP with xxx.xxx.xxx.2 (something I changed immediately). If yours does the same and the address you want to use as static is in that pool, it could be causing some confusion with the static IP.

with frankbell posts, i notice in your settings have dhcp and static.

so I guess system takes the first parameter auto eth0.
take out auto eth0 and static ip addressing should work fine

The auto stanca has nothing to do with dhcp. At least not when its on the beginning of a line. Its just to say that if ifup -a is called that this device should be configured. Also this does not help solve your problem. Just telling so you don't remove it.

MAybe check output of dmesg and take a look at network configuration.

I seem to recall that ifupdown uses the first entry in /etc/network/interfaces for any given interface.

It could just be that you're not in the same subnet with the gateway and client. Both must be in the private A, or B, or C subnets, not mixed. And you have to make sure network-manager isn't running also, because it disables ifupdown.

static IP is not in dhcp pool.
dhcp pool is same subnet.

Its a debian knockoff. I dont know much more than that other than some german guy made it. Its got a tool set in it Id like to use.

for the static IP to work;
the LAN cable connected to your server or pc must be connected to a router or a switch which has the same subnet you had specified on /etc/network/interfaces

I don't think you need to do the update-rc.d after changing your network interface settings. The rc.d system in debian is/has been going through a some changes over the years, and certain parameters in the various configuration files are deprecated. I think the error messages from that step are not part of your problem.

Is that your entire /etc/network/interfaces that you posted, or are there more bits inside? Also, are you using anything like network-manager or wicd in a gui or is this all cli stuff for you?

thanks.

d.o.

Maybe this can help:

Anyway what version of Linux you use might not be important in this case,
just make sure there is no network manager disabling the use
of /etc/network/interfaces file.


Since you are refering to a German made version of Debian
I presume it could be a (live) Knoppix cd or hdd install.
If it is installed to disk it can be changed
and also when booted from cd with the toram boot option that puts it into memory
(runs very fast).
but if it runs directly from cd some important files cannot be so easily changed.

Kind regards and succes
