I have trouble sync

[shia86]

I can't open http://spectrum.s3.amazonaws.com/kin.../wifistub.html due to my ISP.

Of course,i can contect isp with this problem

But i find that i can visit it using ip's way:http://72.21.211.167/kindle-wifi/wifistub.html

At first,we may think is DNS problem,but it's not.
Using `dig` command,i can see that it convert to ip properly
So i write
ip name
in /etc/hosts
But it doesn;t work as i expect.

what should i do

Copy what you wrote into /etc/hosts please, use the 'CODE' tags around it please.
(Note: the Windoze and the Linux hosts file use different formats and line endings.)

Also explain what you expected it to do and what it does.
"Does not work as expected" is worthless, since none of us can get inside your mind.

I expect the /etc/hosts file can take effect and then i can open the website using name not ip

Check that your /etc/nsswitch.conf lists 'files' as the first choice, like this **SAMPLE**:

# /etc/nsswitch.conf
#
# Example configuration of GNU Name Service Switch functionality.
# If you have the `glibc-doc-reference' and `info' packages installed, try:
# `info libc "Name Service Switch"' for information about this file.

passwd:         compat
group:          compat
shadow:         compat

hosts:          files mdns4_minimal [NOTFOUND=return] dns mdns4
networks:       files

protocols:      db files
services:       db files
ethers:         db files
rpc:            db files

netgroup:       nis

72.21.211.200 also resolves to this... as does 205.251.242.101, 72.21.215.165

You sure that IP is still good?

yes, file is in first place

everytime i can open using this ip.

[twobob]

Why not use someone else's nameserver? IIRC that is not such a hard thing to setup.

Still an extra NS record in your DNS resolution thingy - point at someone with decent results?

okay yeah I see http://aws.amazon.com/s3/

fair enough

[twobob]

[root@kindle root]# cat /etc/hosts

127.0.0.1 localhost.localdomain localhost kindle
192.168.15.200 usbnet-host-gw
72.21.195.161 spectrum.s3.amazonaws.com

and you have that?

But it is not the DNS problem as many people pointed out

And if you should, in the future, choose to add the BBB firewall . . .
Remember that those ranges will be blocked on the Kindle.
You will need to manually comment out the block on the access point to the S3 services you want to use.

And the file which twobob mentioned is: /etc/resolv.conf
Which may be over-written by things like your network manager thingy, dhcp, and other "we know best" applications.
Meaning you may have to tweak each of those "we know best" application configurations to make a lasting change in DNS nameserver.

[twobob]

Just so I am 100% clear on this..

It's YOUR ISP that is in some way messing up the resolution of the name. OR SOMETHING.
correct?

That is to say IT DOES WORK when you connect via 3g? correct?

Just trying to figure out how you know it's NOT working. Like, exactly what are you trying to do?

Okay USE CASE:


I open my browser on the kindle (for arguments sake) and type in your IP
72.21.195.161

The browser goes off and RESOLVES this (In the address bar where we can see it) to the aws.amazon.blah.blah.blah

What happens when you do this?

thanks.
