"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Can you ping - for example - www.google.com? Or at least an outside ip address like 8.8.8.8? If not, you have network connection problems. If yes, it seems your 'you' (Yast online Update) cannot connect to the repository servers. The reason could be a subscription problem.

Is your DNS configured? Is your routing has default router that can take you to the Internet?

ping www.google.com
gives me unknown host

ping 8.8.8.8
gives me network unreacheable

Note:  The server is on our network behind the same router. If I do a ipconfig from a windows machine I get an ip address 192.168.229.200
so I belive the router address that the linux box give is wrong.

I sort of think if the server can detect my router then it will get to internet - but I don't know where to set that up.

route command  on the linux machine gives me this
hanab1:~ # route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
127.0.0.0       0.0.0.0         255.0.0.0       U     0      0        0 lo

and
hanab1:~ # ip route show
127.0.0.0/8 dev lo  scope link
169.254.0.0/16 dev eth0  scope link
192.168.229.0/24 dev eth0  proto kernel  scope link  src 192.168.229.149

Open in new window



ifconfig gives me the below

in addition to my reply just before this ( pelase check )
also --  the
/etc/sysconfig/network/ifcfg-eth0
has these information.  below. Asuning the NETWORK= is the router address, should I change the address of the NETWORK= ?    -   do I need a restart of the server ? and what consequences could there be ?


BOOTPROTO='static'
BROADCAST='192.168.229.255'
IPADDR='192.168.229.149'
NETMASK='255.255.255.0'
NETWORK='192.168.229.0'

It seems no default gateway is set.

Please find out your default router IP address (from network admin or from some other m/c connected to Internet) and add. Please see steps in below link:

under "Add default gateway in SUSE Linux"

omarfarid thanks . I could not be sure how to correctly do using your link but I used YasT to update hoping it will do the same job - hope someone can advise
this is what I did and the result

yast - network devices - network settings - routing
default gateway set an ip address to 192.168.229.200
and after a reboot of the system found this line in the routes file
default 192.168.229.200 - -

rebooted the system and also did a manual start of the network but still cannot ping  - same results as before if I ping www.google.com  ,  I get unknown host

can you ping 192.168.229.200 ?

What about your DNS setup?

If you run command like:

nslookup www.experts-exchange.com

What do you get?

If dns is not setup then you need to configure it. You may use yast for this. Please see link:

mbertl -
yes I can ping  192.168.229.200

omarfarid
nslookup www.experts-exchange.com
gives me below
;; connection timed out; no servers could be reached
I will check your link re DNS

omarfaridCommented:
connection time out could be due to:

1- Routing issue to the DNS server
2- Some firewall blocking you from reaching DNS server

Check with your network admin
