Help!!! Urgent!!!! Internet Not Working!!!!

[The Unknown]

My internet story-

Internet was working in F7. I formatted and installed F8.

Now I am unable to get the IP address.

On setting a local ip 192.168.1.2 ; i can login to the DSL router 192.168.1.1 though I don't require it to tune coz reliance dsl is a web-login system @ reliancebroadband.co.in

NOW I AM NEITHER ABLE TO ACCESS INTERNET ON F8 OR F7

AND MY LAN CARD IS WORKING. PLEASE HELP!!!!

doesnt redhat systems default with iptables FW ON?
try as root "iptables -F" for a test and try.I think ur on pppoe builtin dialer mode?

Nilesh,
Im facing the same problem. Even i have reliance broadband connection
when I give the command "sudo /etc/init.d/networking restart"

DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 8
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 15
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 8
No DHCPOFFERS received.
No working leases in persistent database - sleeping.

It worked perfect before without any configuration. Its been like this for 2 days

Yeah its like this since 2 days. I am sending a complaint to broadband@relianceada.com

If they keep this like this then I think I'll have to move to some other ISP

[ChaiTan3]

Seems a Reliance problem.

Yeah I have sent them a strong email. I also stated that if they do not resolve this, then I am going to move to another ISP like Airtel or BSNL.

lol format once again. Maybe you formatted your ISP's servers.

hahaah. nice joke. then how am i on the same internet from my dad's win32 lappy ?

[The Unknown]

Bah! Humbug!!! The technician came home and tried to do something but he was unsuccessful. DSL worked on his win32 lappy but not on my Linux box.

Will Have to look to another ISP.

[mehulved]

check logs, always.

[praka123]

does it come with a router?esp ut300r2u?u can switch OFF the router and connect again while fedora is running.try if fedora's dhcp system detects the IP .
the simple thing u may have tried before?as root,

service network restart

I think fedora got a gui for services;right?
also restart dhcp service too.

[NucleusKore]

Your local IP is set correctly (192.168.1.2, subnet mask 255.255.255.0)

It looks like a DNS problem. Please update your DNS to OpenDNS and see.

208.67.220.220
208.67.222.222

Update: Oops, my bad, didn't read properly. Anyway just try changing the DNS numbers.

[vish786]

prob lies with ur system not with ISP.... roflmao

[ChaiTan3]

Same case here. The reliance connection is working in Windows but not in linux( ubuntu in my case).
In both the OS i have set configuration to automatic.

do you manually give any ip in windows ?

or its set to "Obtain IP automatically"

[ChaiTan3]

Its set to Obtain IP automatically

[NucleusKore]

I am still wondering how can it be a ISP problem. You said Windows is browsing fine. And since you can log into you router, the only two things left to check are
1. Default gateway (192.168.1.1)
2. Primary and Secondary DNS
3. Driver issues !!! funny but see this

Just see this too

[vish786]

system->admin->network *->set it to DHCP settings

on ubunbu -> sudo /etc/init.d/networking restart

on fedora ->login root: /etc/init.d/network start

or else reboot

btw wats the hostname u gave while installing fedora ?

[mehulved]

Can you explain how exactly you connect? You have a dialler or something? Any idea?

[NucleusKore]

You won't believe I just woke up to post this message, it might just work.

DISABLE IPV6

Goodnight

^exactly. LOL!

@NG aka "unknown":try switch OFF & ON ur modem while in fedora.then run(ALT+F2):

gksu system-config-services

^restart suspected services.

[ChaiTan3]

I've disabled IPv6 but still the same prob
heres the output of network restart

[NucleusKore]

Why is DHCPDISCOVER running, haven't you disabled dhcp? Please do so and assign a static ip. Also restart the network post the output of your ifconfig

[praka123]

@chaitanya:the problem is network is unreachable.I am not an expert with n/wing;still it seems that u have to edit the local ip range and/or subnet mask

what about the o/p of subnet mask and be clear,are u on fedora?

also,if u have network-manager thing installed on ur distro,why not purge it out?it is for n00b's who cannot do any network settings.

and what is this service?reliance broadnet using a router ? with webbased activation?

anyways observe the o/p of

route

also acc.to google reliance IP address is like 123.236.x.x or 124.x.x.x etc which is class A afaik so,In router,u may have to set these esp SUBNETMASK value to things may be.also this VPI/VCI things too needs to be noted.
I think reliance CC must be asked regarding the technical details like VPi/VCi,dhcp range,any other technical info to be done in router.

use subnet calculator to calculate if u know the ip assigned by reliance:
http://www.subnet-calculator.com/

I think you should assign 255.128.0.0 as Subnetmask.try!

[NucleusKore]

Praka123 I'd beg to differ. I have a class "A" IP (AirTel), but my subnet mask is still 255.255.255.0
That's the job of any hardware router (or even a linux router ) to interface between two different networks. His internal network can be class C and his external can be anything else.

I still feel as you said, its an IP and subnetting problem, that's why I asked for the output of ifconfig above.

I asked for IPv6 to be disabled as Reliance DNS servers may not be configured properly to handle IPv6 requests. Also, if I am not mistaken, if IPv6 is available, the TCP/IP stack preferrably communicates in IPv6 first and then in IPv4.

So it is advisable to
1) Disable IPv6. Use the system network config tool



Select your interface, click edit, and uncheck the Enable IPv6 configuration option. Enter static IP 192.168.1.2, subnet 255.255.255.0 and save.

2) Then click on manually, type gateway 192.168.1.1, primary and secondary DNS whatever Reliance gives you, or even better, OpenDNS - 208.67.220.220 and 208.67.222.222
Go Next and save your settings

3) In a terminal as root: service network restart

4) ifconfig
and post the output here

For reference: Fedora 8 Network configuration

[praka123]

yup.it is the function of h/w router to resolve the different IP classes.but..here the network is unreachable!some way subnetmask thing needs to be edited to correct value.
I think it needs the help of reliance CC to solve areas along with some linux knowledge

[NucleusKore]

Ok Praka123 lets see. Apparently our man here gets to use the net only at night Hope he is able to get to the bottom of this. I wonder though, why he did not have any problems with Fedora 7.
