Long-time Windows user here -- this is a beginners question, network-configuration (especially on Linux distributions) is not my area. I believe I've done my research, however. Although I might've got some of the terminology wrong.
I'm tasked with configuring a static IP network in Linux openSUSE 11.3 (32-bit, a discontinued release I believe), for which OS I'm doing this for the first time. I need to configure the network taking the following expectations into consideration:
- network is part of the
192.168.146.0/24domain, - network must support at least 21 clients,
- subnet uses as little of the original network as possible.
After doing the calculations, this comes down to the following bitmask:
110nnnnn.nnnnnnnn.nnnnnnnn.ssshhhhh
Where of course n network, s is subnet, h is host. This supports 30 hosts per subnet which is adequate, and from which the following subnets span:
- 192.168.146.0 - 192.168.146.31
- 192.168.146.32 - 192.168.146.63
- 192.168.146.64 - 192.168.146.95
- 192.168.146.96 - 192.168.146.127
- ...
I need to configure the network to use the 3rd usable subnet, and for the host I'm configuring this network on, to use the lowest possible IP address from that subnet (192.168.146.97, I believe). The network interface is eth0, and this is an internal network.
I'm certain either ifconfig or the ifcfg-eth0 file is what I need, but documentation is either sketchy, meant solely as a reference for linux experts, or just not where I should look at. I'm using the built-in Terminal window, and I of course have root access.
Long-story short, how can I configure the network so that:
- the host I'm doing the configuration on has the static IP of
192.168.146.97, and - the network is
192.168.146.96-192.168.146.127?

ifconfigwill work, but the settings will be lost after reboot. If this is just an academic exercise, that's fine, but you'd normally useyastto set things up and store the result into files, and you'd also specify a default gateway, the address of another system on the network to use as the gateway to the rest of your organization.

The file you need to make or edit is called ifcfg <interface>, where <interface>
could be e.g. eth0 or eth1.
On Freebsd and Debian I used :ifconfig <interface> <ip address> <netmask> and it worked please try it.

Just as I thought, this is possible using ifconfig. On the host being configured, type:
ifconfig eth0 192.168.146.97 netmask 255.255.255.224

This is only going to affect the run-time configuration. You need to edit the files underneath/etc/sysconfig/network-scripts/ifcfg-*(in this case/etc/sysconfig/network-scripts/ifcfg-eth0) This file is read when the system is booted or the "network" service is restarted.

@Bratchles Yes, you are right. In the end, I resorted to using yast, which provided a surprisingly convenient GUI for configuration. I believe it is writing to this same file when changes are made.

I've done all the above, but still nobody can connect, and upon investigation I find that it has reverted back to a dynamic ip assigned by the modem (according to ifconfig,) and /etc/sysconfig/network/ifcfg-eth0 still contains the static ip:
# ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.1.5 netmask 255.255.255.0 broadcast 192.168.1.255
ifcfg-eth0 file:
BOOTPROTO='static'
BROADCAST=''
ETHTOOL_OPTIONS=''
IPADDR='192.168.1.200'
MTU='1500'
NAME=''
NETMASK='255.255.255.0'
NETWORK=''
REMOTE_IPADDR=''
STARTMODE='auto'
ZONE=public
USERCONTROL='no'
Yast also shows the ip as static 192.168.1.200, but ifconfig says it's dynamic. What's going on, ho can I fix this?

Yast also shows the ip as static 192.168.1.200, but ifconfig says it's dynamic. What's going on, ho can I fix this?

I've done all the above, but still nobody can connect, and upon investigation I find that it has reverted back to a dynamic ip assigned by the modem (according to ifconfig,) and /etc/sysconfig/network/ifcfg-eth0 still contains the static ip:
# ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.1.5 netmask 255.255.255.0 broadcast 192.168.1.255
ifcfg-eth0 file:
BOOTPROTO='static'
BROADCAST=''
ETHTOOL_OPTIONS=''
IPADDR='192.168.1.200'
MTU='1500'
NAME=''
NETMASK='255.255.255.0'
NETWORK=''
REMOTE_IPADDR=''
STARTMODE='auto'
ZONE=public
USERCONTROL='no'
Yast also shows the ip as static 192.168.1.200, but ifconfig says it's dynamic. What's going on, ho can I fix this?

ifconfigwill work, but the settings will be lost after reboot. If this is just an academic exercise, that's fine, but you'd normally useyastto set things up and store the result into files, and you'd also specify a default gateway, the address of another system on the network to use as the gateway to the rest of your organization.– Mark Plotnick
