The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

problems to configure my LAN

Asked by kar10s in Linux Networking

Tags: host, workgroup, addr, lan

Hi,
First of all, apologize for my poor english.
I need urgently an solution, so I will give another 500 points for a quick solution to this matter.

I have been during several days trying to configure my network without success.I can not see the other pcs on lan or navigate on Internet.(ADSL)

Can I have a step by step guide to do it.

The network runs perfectly on 3 pcs with windows, but I have problems to configure the box with Mandrake
(Runs ok with windows 2003)

  internet -------router
                         | --------- PC1(Mandrake9.1 and windows2003)
                         | --------- pc2(windows98)
                         | --------- pc3(windows98)


router(ZYXEL)
-------
It works as dhcp server . and provides ip addresses to pcs between 172.16.0.5 and 172.16.0.10
Local IP of router =172.16.0.1

When I start mandrake:

[root@PC1 Desktop]# ifconfig

why eth0:9 ? why inet addr:169.254.146.205  Bcast:169.254.255.255  Mask:255.255.0.0 ?


[root@PC1 kar10s]# /bin/netstat -r

127.0.0.0         *               255.0.0.0         U         0 0          0 lo

When I make a ping to router or other pcs on lan (By their names or addresses) I obtain a message that says "destination is unreachable"

[root@PC1 kar10s]# ping 172.16.0.1
connect: Network is unreachable


I have tried a lot of things and modify a lot of parameters in config files.
for example:

[root@PC1 kar10s]# ifdown eth0
[root@PC1 kar10s]# ifconfig eth0
