[maengyi]

I've just installed the fedora 7. And i did nothing, even the update.

But i can't find my pc via network. I tried ping, but no response, also ssh.

Have i forget something or have to do some setting?

ps:
I always can not found my pc via network from i switch to fedora from ubuntu.

I'm new to linux & fedora, What kind of information you need?

Give me some command.

Thx.

It's difficult to know what information to give when you are first starting.

So, question 1, what kind of ethernet card? Is it a wireless card, and if so, do you know what kind of card it is?

If it's not a wireless card, again, do you know what kind of card it is?

(If you're not sure, but have a commercial brand of computer, that is, a Hewlett Packard, Dell, or whatever, please give the model number--someone might be able to guess what sort of card it is from that. If you're also running Windows on the machine, Windows will also have that information).

Did the card work on Ubunutu? (That part of your post wasn't quite clear, whether it worked or didn't work.)

From your description, my most likely guess is that it's a wireless card, and you'll have to do a few things to get it to work, but this often depends upon which wireless card it is.

Yes we need a LOT more info!!!!!!!

At a minimum pls give us the print of the command ifconfig -a
As Scottro mentions, we need to know how you are connecting.
WIth your other machines (or this machine before you put on Fedora7), how was it set up when it was working - do you use static IPs or is it DHCP? (If you have no idea about this and never changed any such settings, it will be DHCP).
Can other machines connect?

hi there bro!
im also a newbie (2 weeks practicing and exploring Fedora6). if you are really a newbie like me, most probably you have made your PCs to "Automatically detect IP using DHCP" without actually configuring the DHCP server itself. That way, you really can't ping. You should configure the DHCP server OR set your PCs to have static IPs. that will ping. if not, then it will be a hardware problem.
'hope I've helped :)

First of all, Thank you all so much for your help.

Now, I can't find out the type of my ethernet card. My card if not a wireless card, And I very sure that, the
driver of this card is good. Because, I using this card to access this forum. The connection to the internet is totally good.

The card was working on Ubuntu, and also can access via ssh.

Here is the information of command ifconfig -a

The IP address of eth0[inet addr](local address) is sat by my self, when i install the fedora. actually, in the case of windows, this address is given by my router automatically.
The IP address of ppp0[inet addr](global address) is given by ISP automatically, & it changes everytime I boot my computer.

As you know, I have local ip address and globle ip address. The local ip address is sat by my self, and globle ip address is given by the ISP.
So, I think I did what i have to do. Maybe i have to set my router.


And I have another guess. Firewall. probably, the firewall blocks all the request from outside. Maybe I have to change the setting of firewall. BUT NOW, I have no idea, how to do that.

[johannlo]

to turn off firewall

as root

service iptables stop

then try pinging the computer should work. Your LAN IP is 192.168.1.10

Thank you.

When i stop the firewall, I can connect to my pc via network. :)

My next job is to configure the firewall. :p

glad to see its working for you.
Another tip: if you have SELinux enabled, some services will behave very strangely unless you configure it correctly or turn it off. When I was a linux newbie, I spent a whole weekend trying to get a samba (windows file sharing) server to work, basically got everything right apart from SELinux and spent 48 hours bashing my head on a brick wall because all the stuff I was reading was linux general, not specific to Fedora /RedHat (like SELInux is).
