my last 2 Fedora 9 Installs i have had to disable the new Networkmanager utility and just enable networking in order to get DNS resolution. With the Networkmanager enabled my setup would not keep the DNS server names/addresses stored.

ah!

We would have got there as part of the network services check, but from your post - as you say - I inferred you were pinging the named address therefore DNS was working.

anyway, all working. well done and congratulations on your debugging.

Yes sorry about misleading you Keratos. Bit of a schoolboy error.

How do turn you network manager on and off.

Thank for all your help. I'm sure it won't be the last time.

turn it off in the services menu

there's a gui from the system menu (in Gnome). Sorry dont use KDE but I guess there is something similar.

you can also use the service command (man service)

tried to run gnome with startx gnome

and got the following error msg - (
EE)Failed to load module "intel" (module does not exist,0)
EE)No Drivers available

Fatal server error:
no screens found
giving up.
xinit: Connection refused (errno 111): unable to connect to X server
xinit: No such process (errno 3): Server error.

I think it has something to do with the graphics drivers. My laptop uses Intel GMA X3100.

use an editor (like vi) to open the /etc/X11/xorg.conf file

search for a line with "intel" in and put a # sign at the beginning of the line.

try again now.

EDIT: in fact Fedora 9 it pretty good at detecting your video config so you should just be able to delete the /etc/X11/xorg.conf file , i.e.

rm /etc/X11/xorg.conf

then try again!

That sorted out xfce which runs fine noe.

Still have the same problem with gnome. It cant find the xorg.conf config file wich of course has been deleted. It then sets up another intel driver and comes uo with the same msg as before.

UPDATE: That was the case until I rebooted and when the system came back up it came up with a gui login and the choice of using either Gnome and xfce and they both work.

So thank you.

I have 2 more probs and then hopefully I will be out of your hair.

I am having trouble with the wireless - I have set the network card but on boot and setting up wlan there is an error saying the ip address is already being used whgich isnt the case. Any ideas? The DNS keeps resetting itself to a wrong address that i first put in when i setup linux.



Chris

well done on fixing your X problem.

okay, the wireless, post the output of the following files (use cat <filename>) where filename is each of the following

/etc/resolv.conf
/etc/hosts
/etc/networks
/etc/netconfig
/etc/sysconfig/network

/etc/resolv
[root@linuxserver ~]# cat /etc/resolv.conf
# generated by NetworkManager, do not edit!



# No nameservers found; try putting DNS servers into your
# ifcfg files in /etc/sysconfig/network-scripts like so:
#
# DNS1=xxx.xxx.xxx.xxx
# DNS2=xxx.xxx.xxx.xxx
# SEARCH=lab.foo.com bar.foo.com
nameserver 172.16.0.240

The 172.16.0.240 keeos resetting to that everytime I reboot.

Change to correct dns's but only keeps them for that session

/etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 linuxserver localhost.localdomain localhost
192.168.1.2 linuxserver linuxserver

/etc/networks

default 0.0.0.0
loopback 127.0.0.0
link-local 169.254.0.0

no idea where the links-local comes from

This is going to be an internal webserver at my school which will provide web services and ftp etc. How should I name it, as it won't be external and have a .net, .com, .co.uk extension.

Hope that makes sense.

chkconfig NetworkManager off
chkconfig --levels 35 network on
/etc/init.d/network restart

then "system-config-network"

I understand that with those commands

you turn the networkmanager off - why? eveything I have read so I need it on for wireless.

you then change the levels and turn network on -why and what does this do.

you restart the network

and then this shows the network config.

It didn't work the wireless still has the same msg as above.
It changed the dns again.

Sorry about asking the why and wherefores but I want to learn not just do it parrot fashion and struggle from one problem to another.

Cal's post was helpful because he was turning off the NetworkManager in the hope that it would not update your settings on reboot, and he was checking that network service ran in runlevels 3 and 5 (multiuser/multiuser graphical).

I was not convinced it was a network manager issue , I still think you have edited some files (directly or inadvertently) that are confusing the system.


Here's one for starters...in the /etc/hosts file, delete linuxserver from the 127.0.0.1 line and delete one copy (you have two!) on the 192.168.1.2 line.

reboot. what happens now.

Thw wlan0 interface has failed again. Saying that 192.168.1.3 some host is already using that address.

After having taken out the bits the server hangs on postfix and just sits there for abt 5 minutes and then boots up.

And the DNS's still disappear.

Any ideas.

Chris

Postfix hanging is normal. it will sit for a very long time during boot if you are having DNS or /etc/hosts problems. Patience, it will eventually give up and continue startup.

I'm not familiar with any wireless connection on fedora, never had to, but i have sure had better luck using the old Network setup stuff than the new networkmanager. I'm not sure why you would need it, setup your info, save it, edit the hosts and resolve file to ensure no problems, and should be good to go.

Once you get into a mess that you can't really figure out how you got there, grab your install dvd, insert it into the appropriate drive, start over. A re-install can take about 20 minutes, you can waste that much time easy. I have also always disabled SE-Linux, never saw a point for it yet on my internal network servers.

Created my own mess this week, tar'd up a user maildir on an old mail server, untarred it on the new server into his home. This changed the /home dir ownership to his name, thus 50 other people could not access their maildirs. Took a bit of figuring to find that one once the calls started coming in.

you have got 3x interfaces setup, certainly eth0 and wlan0 , lets see what the other one is ... i suspect it is this that is causing the problem...we are nearly there mate:
