Guest kedar Posted August 26, 2008 Report Share Posted August 26, 2008 Hi all, I am trying to use TATA Indicom CDMA USB modem on Mandriva Linux 2008 using wvdial. I have edited wvdial.conf file as per company's suggestion and it looks as follows: [Dialer Defaults] Init1 = ATZ Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 stupid mode = 1 Modem Type = USB Modem ISDN = 0 +FCLASS = 0 Phone = #777 Modem = /dev/ttyACM0 Username = internet Password = internet Baud = 460800 I know it works because I have used it on Open SUSE on same computer and have got no problems. On Mandriva, when I run wvdial and then disconnect using Ctrl+C, I get following output: [root@localhost kedar]# wvdial --> WvDial: Internet dialer version 1.56 (abuild@mandelbrot) --> Cannot get information for serial port. --> Initializing modem. --> Sending: ATZ ATZ OK --> Sending: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 OK --> Modem initialized. --> Sending: ATDT#777 --> Waiting for carrier.

I manually created the file but problem persisted. I have also tried adding the two IP addresses in hosts file using Mandriva Linux Control Centre, but no solution. What is happening ? Because of this I am not able to connect to the internet. Regards, Kedar Link to comment Share on other sites More sharing options...
adamw Posted August 26, 2008 Report Share Posted August 26, 2008 Have you tried using the Mandriva network connection setup tool rather than wvdial directly? Link to comment Share on other sites More sharing options...
Lexicon Posted August 26, 2008 Report Share Posted August 26, 2008 My sentence if You use KDE this best is KPPP .....Lex Link to comment Share on other sites More sharing options...
David Batson Posted August 27, 2008 Report Share Posted August 27, 2008 If Adam's suggestion does not work or work well, try kppp as Lex recommends. That is what I use with my HSDPA/EDGE/GPRS card. Tried WVDial and I don't remember if I ever got it to work. I much prefer kppp. Link to comment Share on other sites More sharing options...
Guest kedar Posted August 28, 2008 Report Share Posted August 28, 2008 I have already tried KPPP. But it doesn't recognise my modem, although it is showing correctly in network centre. I have installed open SuSE again. and after running wvdial from it, I have figured out that wvdial starts the ppp daemon (pppd) which then executes the ip-up script. In Mandriva, pppd starts correctly but not ip-up. So, I will take back up of ip-up and ip-down scripts in open SuSE, install Mandriva once again compare the scripts there and get back to you folks.

David Batson Posted August 28, 2008 Report Share Posted August 28, 2008 I have already tried KPPP. But it doesn't recognise my modem, although it is showing correctly in network centre. I suspect you just did not set it up right. See below how I set up kppp to work with my cellular PC Card modem. Of course your setup will be a little different. BTW, kppp is just a front end for ppp - same as wvdial. http://forum.mandriva.com/viewtopic.php?p=399588#399588 Link to comment Share on other sites More sharing options...
Guest kedar Posted September 10, 2008 Report Share Posted September 10, 2008 (edited) I tried using kppp in Open SUSE and my internet connection was running fine there. So I set up the same settings in Mandriva 2008 and tried to connect. Once again I was not able to open any webpages. Following are the messages I got in kppp: Modem Ready Logging on to Network then in kppp's debug window: ATZ OK ATQ0 V1 E1 SO=0 &C1 &D2 +FCLASS=0 OK ATM1L1 OK ATDT#777 CONNECT Starting pppd Then I get a pop-up from system tray Network is up on interface ppp0 But I am unable to connect to internet. Also I have found out from network monitoring programs that after the initial handshake not a single byte is transmitted or received. What I think I missed was commenting out lines in link ifup-ppp script as provided in link by you (but there was no reason to do so in open SUSE) and I am using dynamic addresses (I am seeing correct primary and secondary DNS addresses in resolve.conf). But I will try these out too and let you know. Mandriva 2008 on Acer Laptop Edited by Kedar: I followed the instructions provided by you line-by-line. Still no help Here is the output: root@localhost kedar]# ifconfig eth0 Link encap:Ethernet HWaddr 00:16:D3:ED:C0:A7 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:17 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:128 errors:0 dropped:0 overruns:0 frame:0 TX packets:128 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:11248 (10.9 KiB) TX bytes:11248 (10.9 KiB) ppp0 Link encap:Point-to-Point Protocol inet addr:121.245.29.92 P-t-P:172.23.129.14 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1400 Metric:1 RX packets:4 errors:0 dropped:0 overruns:0 frame:0 TX packets:5 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:3 RX bytes:40 (40.0 B) TX bytes:67 (67.0 B) [root@localhost kedar]# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 172.23.129.14 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0 0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 ppp0 What am I missing ?
