BSNL broadband problem

[prasanthsd]

Hi

I can actually connect to the internet. The problem is I cant connect to certain websites. At first I thought it was some DNS problem thats frequent with BSNL. But in windows they work perfectly Tried fedora and ubuntu both have the problem. What would be the issue?

Thanks in advance.

Two things that jump to my mind.

1) DNS server, try OpenDNS.

2) CHeck the MTU value, output of ifconfig

If you are able to suft websites in windows, then its not a BSNL problem.

May be something is blocking/filtering the web in fedora and ubuntu.

Try openDNS or Google Public DNS as others have suggested.

Also, try to open those sites using any proxy site, like:

http://anonymouse.org/anonwww.html

Change your MTU to 1432 or 1482..

Yeah tried openDNS earlier didnt work. But thats not a solution right when its working on windows without openDNS?

Welcome to Indian Railway Passenger reservation Enquiry this one does not work. when seraching around others seems to have problems with linux on the same sites too, but i couldnt land up on any solutions.

tried to alter the MTU value from the network manager but still if config shows the value of 1492 for ppp0

Its not the DNS error.

My net was down since 7 AM in the morning. Connection was getting established only for few seconds and then the traffic LED would be on a vacation.

Just been normal for the past 30 mins or so.

Worst downtime since i started using BSNL (2005). Today being a Sunday didnt helped one bit.

I THINK I fixed the issue. Changed the MTU to 1454. Let me browse around for a while and see if its really fixed. Thanks for the help guys

 

[prasanthsd]

Ok each time i boot i have to do sudo ifconfig ppp0 mtu 1454

I have set the connection not to automatically connect. When i want i use the network manager applet to connect. I have tried to set MTU in the network manager connection editor but It didnt work. Also tried to edit /etc/netowrk/interfaces that didnt work either.

Any solutions guys?

Perhaps you could try checking in the router/modem options for setting the MTU?

 

[prasanthsd]

Looked around the router config couldnt find anything relevant.

If its possible to set that in linux it will be great. can somebody offer some light?

are you using static IP or DHCP?

Some sites were always showing 500 - internal server error, on my BSNL broadband. All I had to do was o change the dns.

 

[prasanthsd]

DHCP i guess. Thats how all dataone connections are right?
