I am using the address listed on the note of the computer, it looks like an IP address, and its first 3 numbers are the same with the gateway. So I think this is the IP address.

when I type
ifconfig eth0 [IP] netmask 255.255.14.0 bcast 129.112.14.255 up
result is

SIOCSIFNETMASK: Invalid argrment
bcast: Host name lookup failure

what did you use as IP address?

and now I can't access google or any other websites.

when I type route -n
there is only one line
and the gateway is 0.0.0.0

129.112.14.31

?????????????????????????
okay, in order of execution, enter this,please

next

and try to ping google

let's see

I typed

ifconfig eth0 129.112.14.31 netmask 255.255.14.0 bcast 129.112.14.255 up
result is
SIOCSIFNETMASK: Invalid argument

and I typred
route add default gw 129.114.14.254
result:
SIOCADDRT: Network is unreachable

and why the bcast is 129.112.14.255 and the route added is 129.112.14.254
it's not a typo, right?

of course, netmask 255.255.255.0, then...

Can you get extra info from teh campus' IT manager?

Hello everyone,

Just trying to catch up.

Let us start from beginning. As OP said that the issue is he is able to browse sites when he log in with root account but he is only able to browse google when he login with any other account. At first instance it does not appear to be me as a network issue the reason being if it was then root user should also not be able to browse the internet. I may be wrong but this is what I think.

omizt,

Is the issue still the same? Are you able to browse the sites with root user and not with a regular user? If yes, could you please try creating a test account and see if you are able to browse sites using that account. If not then try the following thing:

1. Login to the machine using test user account which you have created.
2. Open up terminal
3. su - root
4. Enter the root password. Make sure your prompt chage from $ to #.
5. Run the following command:

Try to browse the sites using this firefox and let us know if you are able to browse. If yes, then it appears to me it has either sometime to do with permission. If not then it has something to do with profile.

Apart from the above test it will be good if could share the output of the following:

1.2.3.4.5.

Hi Thor_2.0,

You're welcome.

After a long time we are in the same thread :-)

Yup, and happy to be! Maybe I can pick something up...

I was able to access the internet under root account, and was not able to access the websites except google in another account(let's say account B). At that time, I set up another test account (account C). Using account C, it's the same situation with account B. I can't access any other websites except google.

But now I can't access any website even under root account.
And I don't know what's wrong.
I think I just use the command of "ifconfig" or "route add" like I was told.

so should I change into the test account? or just stay at root account?

@ Thor

Same here. :-)

@ omizt

Don't worry, it will be fine. If you could share the output of the commands that I have mentioned then we will be able to help.
