I am a very beginner in Linux. I have installed fedora Core 1 and I would like to
know what is my domain to be able to connect my machine throuth telnet.

Thanks

First, use ssh, not telnet, which passes passwords in plain text.

Anyway, how can anyone answer your question without any details? Where is the machine and how is it connected to the internet? Or you talking about dns domain or thinking of something like a Windows domain?

Generally, ssh to a machine can be done with ip address or dns name.

BTW, if you're thinking of connecting via a Windows box there is a free ssh client for Windows called Putty, so that you don't have to resort to telnet.

Steve,

I will use ssh instead of telnet. Anyway, I am in a dynamic DNS and dynamic IP network with all other computers running Windows and I just want to have access to my machine from the other computers (that run Windows) via ssh or whatever.

As I said I am a very beginner in Linux and also in subjects related to network, and I do not know how to identify my computer in the network to be able to use ssh. I tried to rename my machine editing the /etc/hosts as:

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
127.0.0.1 mcslinux.okstate mcslinux

but it is not working. When I try to run telnet mcslinux.okstate.edu from Windows nothing happen.

Thanks

wether or not you can use a hostname depends on several factors. You can either have someone that manages DNS for your network to add an entry for you box, or you might have a hostname assigned to you automatically.

you can run ifconfig eth0 (assuming your network card is eth0) and get your ip address. Then just use that to connect. If you have contact withthe network admin, try to get an IP specifically set for your box (so IP doesn't change often ) and maybe even get a host name entry in the DNS server.

I have a similar setup at work and have my workstation email me its ip in case it changes, but let's save that for later if you want to know how.

One thing about ifconfig: if not running as root in the terminal window you'll probably have to use the full path. Mostly likely it's /sbin/ifconfig.

Try "locate ifconfig" if you can't find it, or do an "su -" first.

Also, I'd change the /etc/hosts entry back. The 127... is the loopback address for localhost. It is not networkable.

Try this: From the Fedora menu--probably the hat--in the lower left corner, go to System Settings, then Network. Enter the root password when prompted. On the devices tab, look for a device called "eth0", highlight it and click the "edit" button. Click the button for "Automatically obtain ip address settings with" and make sure that the drop down box is on DHCP. Click ok. Back at the initial tab you may have to do a "file, save".

That should set you up for DHCP to get a network address automatically just like the Windows boxes.

You can change this later if you get a fixed ip like paintcheck mentions.

They proved domain naming solutions for non static ip's.

Been using em for a year now, brilliant !!!!!

Did i mention it was free??? Heh
