Trying to set static IP opensuse 42.1

No, a firewall is an essential part of security. At the very easy a router with NAT and firewalling implemented.

Please excuse me, I am not trying to oppose your suggestion good sire, is it optional to have a firewall? coz what i have here is a test PC. for some reason, that i am not quite sure… HDD is cloned from another PC… is it possible that i am just having an issue with a mac address or does it retain the previous IP settings before configuration, Apologies for my dull conclusion, i haven’t navigated much about this PC and all i did was follow a set-up guide from youtube and stuff accordingly. but your suggestion is very much appreciated

Thanks!

Your unprotected machine is visible to the world. If I were you I’d disconnect it immediately. I’ll send you a PM with the port scan results I just got. It’s not the correct way to connect the machine to the internet. You will get hacked!

You also need to tell us whether you’re using NetworkManager or wicked

systemctl status network

The output will quickly tell you which service is running.

I am using a wicked network since its the only one available from the option

For a server with a network connection that is not likely to change that makes sense.

Get yourself a decent router with ethernet WAN port, so that your network looks like this

DSL Modem-----(WAN port)Router/Firewall(LAN port)-----Your server

Your server can be set up with private IP address (DHCP via router or a static IP address). If the server is going to be used as a web server you will need to configure port forwarding in the router. There are lots of guides on how to do this when the time comes.

Just to give you a basic idea…

Thank you good sire,

I will immediately look for decent router with your advised feature. hope i still get answers when i get back soon

Thank you so much!

[deano_ferrari]

Just for completeness. I checked the vicibox instructions… in particular the network configuration section, and it mentions about assigning a static IP address (via YaST > Network Devices > Network Settings). When you do this you will need to assign an IP address, netmask, gateway address (which will be the router address), and valid DNS servers for name resolution.

HOWEVER, all this assume that you are behind a router - not directly connected to a DSL modem. So, do that first and we can help you again when you get yourself sorted.

Thinking about what you posted,
I verified that whoever is configuring your networking made a fundamental design mistake.

Is one reason why I insisted on knowing your netmask…

Which is 32 bits and never used except in very rare instances.
Here is a netmask table if you don’t want to do the calculations yourself…
http://www.unixwiz.net/techtips/netmask-ref.html

As the table informs,
A 32-bit netmask only allows for one valid host address.
Which means that you can certainly configure an address, but not another for a second machine.

No, the DSL circuit is likely using PPPoE. A /32 address is often associated point-to-point links like this. The OP needs to install an internet-facing outer.

See here for example…

How would a router with /32 WAN subnet mask communicate with the rest of the Internet?

ok, yes.
post #16 says he’s 'connecting directly to a modem."
And, that is one of the “direct connection” scenarios where a /32 netmask can be valid.

In that case, his configuration is radically different.

So, to the @OP,
Did your ISP provide you with specific information how to set up your connection?
Simplest is to simply drop in a device but with the right information you should also be able to configure your openSUSE without a special device (but requires work).

If you’re really setting up a PPoE on openSUSE, I recommend you do this in Network Manager

Good Day,

They didn’t provide stuff, they just gave us what our Static IP assignment will be which is somehow easy to find, that’s it. since they didn’t want to step-in with the server configuration which i thought would be smooth since i have followed a guide from installation and stuff which didn’t gave me much trouble until this eth0 issue configuration.

Thanks!

Ask to speak to someone higher up.
Ask to see your ISP agreement about whether you can set up your own Gateway device.

Assuming you really are setting up a PPoE device,
As I described, open up your Network Manager and explore the steps to set up a PPoE connection, that’ll tell you what your ISP needs to provide you.

Good Day,

Thank you so much for your suggestion good sire, i will contact my ISP and seek for assistance immediately.

Thanks!

Just wanted to ask if there is a possibility to access a routers GUI on openSUSE?

Thanks!

Do you mean that you now have a router, and want to access its web interface? If so, use a browser. Just point it at the gateway address.

Good Day,

It will arrive within the day sir, I ordered the most affordable upon your recommendation the same day you mentioned i need a firewall.
btw Sir, just for clarification, I have to plug it on another PC to configure it right?

Thanks!

Yes - any PC that you can connect to its LAN port.

Good Day,

I am a bit confused why it shows 192.168.1.4 on the static IP, also i tried setting up the openSUSE PC’s mac address i’ve seen some of your guides to get it and tried to input not sure why it doesn’t accept my input. apologies for the trouble.

Thanks!

You need to explain a bit more to us. We’re not over your shoulder to see for ourselves

Have you connected your local machine in to a LAN port? The router should be connected to the DSL modem via a WAN port.

DSL modem----(WAN port)Router(LAN port)----local machine(s).

[xlyreb]

Apologies for my vague details,

I double checked the set-up and indeed, it was DSL modem–(wan port)Router—(lan port)Machine set-up i did.

Any static IP address that you assign for your ViciBox should be in the same subnet as your LAN.

From the router image you sent (via PM), it appears that the router is configured to provide DHCP addresses in the 192.168.0.0/24 address range.

If you can reserve an address for your ViciBox then you can simply configure this to use DHCP and it will get the same address served each time. Alternatively, you might also be able to restrict the range of IP addresses the router can serve, and then you can configure your server to use a static IP (eg 192.168.0.100) outside the DHCP range (192.168.0.2 - 192.168.0.99).
