Sorry to bother you good folks again quite so soon, but I'm still having
problems with my new machine.
I've just installed FC5 to a brand spanking new machine. I've managed to
get most things working, including being able to use grub to boot linux
from an IDE drive, and W2k from a sata drive.
I do still have some problems though, and given my lack of experience I've
exhausted all my own thoughts and ideas.
Problem 1
The mouse pointer vanishes as soon as the login screen appears. This is
less important as I can get by without it, but it is irritating as I have
to guess where the mouse is pointing.
Let me say first that I am no guru.
If it were me, I would run linux in text mode for the time being
(by responding "linux text" to the boot prompt)
and hope to sort out the mouse problem later.
In principle you need correct mouse (pointer) setting
in /etc/X11/xorg.conf , but this is normally setup automatically.
Problem 2
The ethernet device starts okay during boot-up, and the configuration
utilities all say that it is configured and working. It can ping itself
using both the loopback address and it's own IP address, but it cannot
ping anything else on the network, and nor can anything else ping it.
I'm using static IP addresses throughout as one of the machines that
connects to the network runs RISCOS3.7 and this has no useful DHCP
support.
Networking should work equally well with static or dynamic addressing.
(You can use dhcp even with static addresses, I believe -
well, I know, as I do it.)
I think you just have a problem with routing.
Did you try "system-config-network"?
But you can setup routing "by hand" using the ip or route commands.
Ive added the appropriate IP to the hosts files of all the machines, and
added their IP's to the new machine. I tried disabling the firewall just
in case that was causing a problem. SElinux is installed but only at warn
level. I've tried reconfiguring the network from scratch.
The ethernet chip is an nVidia CP51 on the motherboard.
You could run "lsmod" to see if an appropriate driver is loaded.
I would suggest you run "ifconfig" and "route" and post the results.
As I said, I am no network guru,
but it sounds to me as though you just have a small configuration problem.
Problem 3
This could be related to problem 2. I cannot run the software update or
add/remove software routines, as both then throw up a box saying
'Retrieving update[software] information', which then fail after about 30
seconds saying 'Unable to retrieve update[software] information'.
If you cannot access the internet then updating will not work.
