Re: [opensuse] Re: simple LAN

Eberhard,
my complaint ("not easy") refers mainly to Ch 21.4 Basic Networking in
the SuSE documentation. It's really too long and complicated to set up
a simple LAN, and it asks to enter IP addresses but never mentions
ifconfig or ip commands to find them.

Regards, Robert

Hi Robert,

Congratulations!!!
It's easy, isn't it?

No. Kenneth on this list learned me about the command ip a which is
not mentioned in O'Reilly's Nutshell or the SuSE manual. Ch 21,
Basic Networking in the Reference documentation should include info
about how to find unknown IP addresses of computers in a LAN.

well, Kenneth's command works but I think, the more usual command for
this is:
/sbin/ifconfig
This is surely documented in the Nutshell. And it is easy, I memorize
it as i(NTER)f(ACE)config(URATION)

Yes, it covers two pages in the Nutshell.

If you are root, a simple "ifconfig" works, as an ordinary user, you
need /sbin/ifconfig

but only after tearing down the firewall

on machine fam, I assume?
That is ok, if your internet router acts as a firewall for your
local network.

It is a Speedtouch ADSL modem. Don't know about firewall
capabilities.

At least something is giving you the 192.168.x.x ip Adresses. If they
come from your Speedtouch and it converts them to "real" Internet
Adresses, this acts in fact as a router.

If you feel better enabling the firewall on fam, you need to
allow ssh traffic on port 22 as has already been said in another
mail. You can do that easily with yast on machine fam.

No. I can't find it in YaST2 / Security and Users / Firewall.

Yes, you can: ;-)

Yast2 / Security and Users / Firewall / Allowed Services (for
External Zone) / Service to allow / choose SSH from the List / klick
on Add
And: you are done!!

Don't understand. I use fish (or sftp, not ssh) to transport files in
the LAN which I suppose is in Internal, not External Zone. Port 22 is
never mentioned in these zones.
I'd like to put the firewall between the LAN and the Internet.
Currently I pull out the phone line from the router when I disable a
Firewall.

In case that there are more problems that you encounter or you have
more questions, just do not hesitate to ask.

This list has only one sole reason for existence: It is here to help
people achieve what they are heading for!!!

I was amazed that so many people responded to my question. Thanks to
all!

And Linux may not be easy, especially when you are beginning to
explore it, but chances are, you will never ever regret it.

I use SuSE Linux since vs 8.2 and explore other distros on 3 other
partitions, but SuSE is my favorite.

Eberhard

Kind regards,
Robert
