[Ilugc] Need Help Sify Vs Linux

Have you tried this when you are not able to browse?
If this is successful
when you are blacked out from internet, then your
service provider is not
blocking your http and most probably your browser is
at fault (because you
are able to access port 80 from a different
application). If your telnet on
port 80 is also blocked, then there is some problem
with your modem or
service provider. In my opinion, service provider will
never block any
traffic simply because the OS is Linux, so the second
possibility is very
rare.(I am assuming that "ping
www.google.com" is successful when you are
blacked out)
By the way you should have tried "GET /" and
not "/ GET", though it doesn't
make any difference in this trouble shooting.

Hi Muneer,
That i did when I 'had' access to the net. Then after 30 minutes later when it
went down I tried this and the output is:
root@ubuntu:~# telent google.com 80
-su: telent: command not found
root@ubuntu:~# telnet google.com 80

When I try to ping Google, this is what I get:
root@ubuntu:~# ping google.com
PING google.com (64.233.167.99) 56(84) bytes of data.

Another strange thing is when I am blacked out:
1. I cannot browse the Internet whereas when I put Microsoft.com, it opens
flawlessly. It cannot open any other site.
2. Even Synaptic can download things at good speed.
3. However, Synaptic cannot index repositories when I am in 'no net cloud'
However it can 'download and install software.
4. If I use any other Internet application, it works well.
5. Sites it opens is Microsoft.com, winap.com, download.com, cnet.com etc but
not other like google, yahoo, ubuntu and many more...
This all is making it complicated. If there is something wrong with browser,
why does it open sites at sometimes but not at other times...?
