Re: Ethernet Questions

Re: Ethernet Questions

[Ray Olszewski]

OK. Networking 101. Your system needs a valid IP address, a routing table
that includes a route to a working gateway to the Internet, and access to
DNS servers that can resolve names for you. (It may need other things too,
but this is the base.) To let us help you figure out what it wrong, report
the following (from your machine, AFTER it has received its DHCP lease):

        1. The complete, exact output of "ifconfig -a"
        2. The complete, exact output of  "netstat -nr"
        3. Try to ping the IP address reported in step 1.
                Tell us either that the ping works or EXACTLY
                how it fails ("-1" isn't enough; we need to see
                the text that precedes the -1).
        4. Try to ping the gateway address reported in step 2 --
                the routing table (assuming there is one).
        5. The contents of the file /etc/resolv.conf .
        6. The results of pinging the first address listed in
                /etc/resolv.conf .

You may also have a hardware problem. I don't want to take the time to write
out those tests right now; if the results of this first set suggest a
hardware problem, I'll return to it. Oh, one more thing ...

        7. The output of "uname -a"

In responding, please don't paraphrase or summarize the results. From what
you have written,I'd say you don't know enough to decide what is and isn't
important in the output. Provide the details, though, and I (or someone else
here) can probably help you.

Linux Mandrake Startup

[Richard Foy]

Up until a year ago I used Amigas. Then I got a laptop pc running windows.

Recently I got a PC box with a very simple "Internet Appliance" linux system
on it. Now I have installed Linux Mandrake 7.2. I have managed to get it to
startup and show a screen where I can login as root or as a user, and thus
get into a bash shell.

However, I haven't found out how to get into a graphical interface, either
KDE or Gnome. when the system is booting it runs by lots of things but I
don't see anything that appears to me that would allow me to get into KDE or
Gnome.

I never seem to see the little window that my manual shows that shows
"Session type" and then a pull down item with KDE in it.".

Can someone give me a clue as to what I need to look for?

TIA

Richard

Re: Linux Mandrake Startup

[docv]

Assuming you are able to log in, you must start an Xwindows session, 
which if Mandrake is like it's parent RedHat (which is what I am 
running), should automatically run KDE or Gnome. You should be able to 
do this by using the command 'startx'.

I don't know Mandrake specifically. But during the install process, yuo
should have been asked about installing X (or X11 or X11R6) ... providing
information about your video card, your monitor, and perhaps other things.
KDE and Gnome are both windowing environments for X, and you might have been
asked about installing either or them, or Mandrake may automatically select
one to install.

There are two ways to start X ... as the default login method or from the
command line. Apparently your system does not use it for login; to start it
from the command line, type "startx" and see if you have any luck. If not, X
may not be installed, or there may be an error in installation that prevents
it from starting.

A Mandrake user may be able to give you more help, help that is specific to
your distro. My comments are at the generic-Linux level.

Re: Ethernet Questions

[Paul Furness]

I'd just add to all the info you have been given that you generally need
to be root to run most of these commands - not because you need root
privelages, but they are usually not in the defined command path for
normal users.

ifconfig is usually in /sbin or sometimes /usr/sbin, so if you are a
regular user other than root and you type "ifconfig -a" at the prompt
your system is likely to complain that ifconfig is a "command not
found". If you do it as root, it should work fine.

I only played with mandrake a couple of times, and that was over a year
ago, but it definitely had ifconfig installed.

If you are really missing this and possibly other essential system
tools, it is possible that your install didn't work right or you
accidentally told it not to install some stuff which you (at the time)
didn't recognize as important.

Worst comes to worst, it could possibly involve a rebuild of the system,
selecting different install options, but hopefully you can avoid that
for now!

Paul.
