wired network connection troubleshooting

[jeretraca]

Hello friends

I have this problem with my wired network connection when i put in the manuat static ip adresses it doesnt go on and connect it tells me you are connected to a wired connection but on pinging any of the adresses in my network says unable to reach host

it tells me i have to restart the computer or network to be able to cange into the new manual static ip adress it does nothing after restart the ip adress typed in manually is deleted every ti me i put it in

Just a thought. Do you have the primary and secondary DNS entries configured? Also, the DNS search path? These can be found under System > Administration > Network.

[jeretraca]

well yes the primary dns
and the secondary dns are both configured as 195.202.64.1 and 195.202.64.2 well the dns search path what is supposed to be put there
one more thing after putting in the dns and dynamic ip adress gateway and all it demands a even restart the machine which i do dutifully after retart the active connection information on the menu bar tells me
interface wired ethernet (eth0)
speed unknown
driver tulip

ip adress 169.254.15.240
broadcast adress 169.254.255.255
subnet mask 255.255.0.0
primary dns nothing
secondary dns nothing

which is very different from the static ip adress i put

i have tried a variety of commands ithe following order

chconfig network manager off
service NetworkManager stop it said ok
chkconfig network on
reconfigured my settings
then lastly service network start

the following came up
bringing up interface eth0 RTNETLINK answers: invalid argument
then ok
all the commands have to be carried out through
/sbin otherwise they dont work on /etc

on trying the command
/sbin/service NetworkManager restart
it failed on the stoping of the network manager but suceeded on the
the starting up of the networkmanager is that an indicator of the problem

Here's your problem. NetworkManager does not work with STATIC ip addressing. If you want to use static addressing you will have to disable the NM services and configure your network settings at system ->administration ->network.

well Iam new user to linux i dont quite know how to do that to disable network manager the commands i run i just copied from a website so how do i do that

[Iron_Mike]

Goto system ->administration ->services, and remove the check marks from the 2 Network Manager services, then stop the sevices and save it. Just to clear things, peform a reboot. Now goto system ->administration ->network, highlight the device you want to change network settings and click the "edit" Uncheck the option "controlled by Network Manager" and add check marks to "allow users to enable/disable device" and if this is going to be a stationary device you can add a check mark to "activate on boot". Next uncheck the settings for DHCP and DNS and set it to STATIC then fill in the blanks for you Network. Make sure you fill in the gateway and double check the dns tab to make sure you have the correct DNS servers listed

Thanks Iron_Mike Ihave done all that it tells me i need to restart my network so in the network part of services i selected network as selected restart this is the error i got

selinux AVC denial click icon then the following is shown

Selinux is preventing /sbin/arping(netutils-l) "write" to pipe (unconfined-t)

what does that mean

[Iron_Mike]

It means SELinux is preventing the operation. Open a terminal window and change to root permissions using su - (the dash is important) and then type:

system-config-security, and set SELINUX to "permissive" or "diasbled" and test it again.
