Hi list, Please enlighten me if you have any experience with using the Tata Indicom USB Modem under the Plug 2 Surf scheme. I have recently taken their subscription and facing problems using it with Kubuntu 7.10 It works fine in windoze, but fails to get any data transfer in Linux. I tried connecting using wvdial and also using KPPP.
The following is a copy of what i get at the terminal on running wvdialconf:
$ sudo wvdialconf /etc/wvdial.conf Editing `/etc/wvdial.conf'.
Scanning your serial ports for a modem.

//////// It appears that it successfully detected a USB modem and created a wvdial.conf file accordingly.
But on trying to dial using "sudo wvdial", i get the following on the terminal:
kamal@kMax:~$ sudo wvdial WvDial<*1>: WvDial: Internet dialer version 1.56 WvModem<*1>: Cannot get information for serial port. WvDial<*1>: Initializing modem.

... and so on and so forth.. it keeps repeating connection attempts and gives the same error "WvDial<Err>: Connected, but carrier signal lost! Retrying..."
I have used wvdial for MTNL Garuda's USB modem on the same installation and it was working fine back then. Also, there was an existent wvdial.conf file with those old settings for MTNL Garuda connection until i executed "wvdialconf" again for the tata indicom USB modem. [* wvdial gave the same problem even with Ubuntu 7.04 installed on the same machine.]
While when i tried connecting with KPPP on Kubuntu 7.10, it did succeed in connecting, that is, it showed me that its connected and the USB modem's indicator too indicated a connection. But i still could not surf the net (or ping any websites)
Am i missing out something while configuring the connection. Could this be an issue with the DNS? The same modem is working fine for windoze on the same machine.
Any help or your experiences in this regard are greatly appreciated. Thanks.

check if you can ping them! ping 202.54.15.30 etc.. also if you might have eth0 or other interface on, check the default route # route -n

Thank you all; that was a great deal of help. I added the "Stupid Mode = yes" line in my /etc/wvdial.conf and that made wvdial to successfully get me connected, however that just took me one block ahead of where i was. It still isnt resolving any URLs. Firefox shows me the "Looking up...." msg for quite a looooooong time and then gives up eventually.
And if i got it right, i guess "disabling Carrier Check" is the same as adding the "stupid mode = yes" string in the conf file or is it something else?
Also, I tried using the OpenDNS service, by using their DNS server IP addresses, but it still changes back to another set of DNS ips the moment i disconnect and redial, may be because we are not assigned any static IPs by Tata Indicom(?)
Please help with this. Thanks a ton in advance.
PS: Please confirm if the list received multiple copies (7) of my mail in the beginning of this thread. I regret any inconvenience to you because of that if the list did receive all those mails shown to me only in my web-mail interface. I had no idea about them when i sent out the mail using Mozilla Thunderbird.

Does DNS work after using OpenDNS? If yes, then you can add OpenDNS IP's to the required configuration file. I am not sure as to which is that. Maybe you can try the solutions enlisted here - http://forums.opendns.com/comments.php?DiscussionID=235

km needs to add the opendns entries *after* the connection is established. It is being overwritten by DNS supplied by ISP but I don't think this is root cause of his problem.
I think km needs to verify his routing table as someone else pointed out earlier. If he has multiple interfaces like eth0 and ppp0, his earlier default route may be interfering even though ppp0 over WLL is established.
km, after the connection is established do a:
# route -n
this will give your routing table entries. If the default route is thru eth0 then you need to delete it (man route).
Alternately, before connecting to Tata, stop your networking (/etc/init.d/<network-script-name>), connect to the ISP, this should give you a workable routing table.

As per that thread, there is an option Auto DNS, setting it off might help, as in the case of one of the people there.Thus, the /etc/resolv.conf file won't be overwritten.

is there a way it can be worked around in Ubuntu? It worked fine with doze. All i needed to do there was enter the DNS server-ips of opendns mentioned on their website and it worked fine (on the same connection - tata indicom plug2surf).

I gave you a workaround; you have not reported yet whether it works for you or not.
read my other post, even though there is an option to ignore ISP DNS, the Ubuntu wvdial ignores it in and pops in the DNS servers from the ISP (this has been my experience).
Anyway, given that you have 2 NICs and now a Indicom connection (3 'net connections), you basically have a "def. route" routing problem.

I second that. In our excitement to get things working we forget about the existing eth0 that's the default route.
KM, simply run 'sudo route add default ppp0' after your usb modem's ppp0 is up. Once this is confirmed to be the solution, remove or comment the default gateway entry for eth0 in /etc/network/interfaces and reboot your machine.
Yes reboot, not restart networking services.

Many thanks. I think this is what got me going. However, I am sure I did something wrong with the commands initially and got it all screwed up. :P
AFAIR, after doing a # route del default gw I did not find the /etc/network/interfaces file in place; it just disappeared! (is this expected? could not understand that from the man page on route`.)
However, I had a backup copy (incidentally a much older, cleaner backup :P ) of the interfaces file that i restored. And things seemed workable henceforth.
Although, this seems to be a pretty dirty way of getting around a problem and i am still foxed as to what was a proper systematic approach to solve it. I am reading up on this, and will surely catch up pretty soon.
Apologies for late response. Reasons include trying to figure out things the D-I-Y way, though i wonder how much that worked :P, and of course, work-loads a wee-bit heavier than i could handle. :)
Many thanks again to all who helped. :)

No. route addition / deletion does not affect the interface file or the current ip.

usually in pppconfig there is an Advanced - Defaultroute option. you should enable defaultroute. Or simply edit /etc/ppp/peers/<your ppp config-name file> and add a the word defaultroute on a new line.
One can of course do all sorts of things by adding appropriate scripts in /etc/ppp/ip-up.d/ and /etc/ppp/ip-down.d/

the conf files and wvdial options are different. wvdial would not connect with cdma and gprs connections many years ago and used ppp since.

You can comment the entries you think are not necessary. If you are no longer using the ethernet, you can simply keep two lines. This is useful for those who use cablenet pppoe where there is no static ip for ethernet and no dhcp server at the other end.
auto eth0 iface eth0 inet manual
If you are not using dsl-provider, you can replace it with the one you are using (pppoe). The name should exist in the /etc/ppp/peers directory. The PPPoE entry is written to the interfaces file only because you pressed enter when you were asked if you want it to start during boot time.

i guess this is what i should give a try, however i have no idea what a routing table is and how it works. but i do have eth0 and eth1 attributed to the 2 NICs jacked in, and used eth0 to access the net for quite sometime before switching to Tata Plug2Surf.
Alternately, before connecting to Tata, stop your networking (/etc/init.d/<network-script-name>), connect to the ISP, this should give you a workable routing table.
err.. any sure-shot way to figure out the <network-script-name> if i dont know it? and how do we stop it?
Thanks a lot for all the help. :)

how about "ls /etc/init.d/*net*" ? this should give you the network script name. Execute the file without any arguments and it will show all the options. You will have to do it as "root" user.
Suggest you get familiar with basic Linux sys admin, there are several excellent e-books.
Start here http://www.linuxtopia.org/online_books/linux_for_beginners_index.html
Disable the "Carrier Check" option and it should work fine.

Hi list, Please enlighten me if you have any experience with using the Tata Indicom USB Modem under the Plug 2 Surf scheme. I have recently taken their subscription and facing problems using it with Kubuntu 7.10 It works fine in windoze, but fails to get any data transfer in Linux. I tried connecting using wvdial and also using KPPP.

WvDial<*1>: Sending: ATZ WvDial Modem<*1>: ATZ WvDial Modem<*1>: OK WvDial<*1>: Sending: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 WvDial Modem<*1>: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 WvDial Modem<*1>: OK WvDial<*1>: Modem initialized.

WvDial<Err>: Connected, but carrier signal lost! Retrying... WvDial<*1>: Sending: ATDT#777 WvDial<*1>: Waiting for carrier. WvDial Modem<*1>: ATDT#777 WvDial Modem<*1>: CONNECT WvDial<*1>: Carrier detected. Waiting for prompt.
... and so on and so forth.. it keeps repeating connection attempts and gives the same error "WvDial<Err>: Connected, but carrier signal lost! Retrying..."
I have used wvdial for MTNL Garuda's USB modem on the same installation and it was working fine back then. Also, there was an existent wvdial.conf file with those old settings for MTNL Garuda connection until i executed "wvdialconf" again for the tata indicom USB modem. [* wvdial gave the same problem even with Ubuntu 7.04 installed on the same machine.]
While when i tried connecting with KPPP on Kubuntu 7.10, it did succeed in connecting, that is, it showed me that its connected and the USB modem's indicator too indicated a connection. But i still could not surf the net (or ping any websites)
Am i missing out something while configuring the connection. Could this be an issue with the DNS? The same modem is working fine for windoze on the same machine.
Any help or your experiences in this regard are greatly appreciated. Thanks.
