I have written the title as "Fedora Core 5+Nokia 6070+CA 42+AirTel GPRS" so that searching for this particular problem might be easier. & if this problem is sorted out it can also help out many other newbees with same problem. I have Nokia 6070, a CA 42 USB-Serial Data Cable, AirTel GPRS connection, which works fine on Windows XP. After searching a lot how to connect the phone and use GPRS via the cable I came across this UBUNTU forum guide. I did not knew about WvDial before. I did just as mentioned there and configured my wvdial.conf which now looks like :- _______________________________________________ [Modem0] Modem = /dev/ttyS1 Baud = 19200 SetVolume = 0 Dial Command = ATDP Init1 = ATZ Init3 = ATM0 FlowControl = XONXOFF [Dialer Defaults] Modem = /dev/ttyUSB0 Baud = 230400 Init1 = ATZ Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 ISDN = 0 Modem Type = Analog Modem Phone = *99# Username = * Password = * Stupid Mode = 1 ________________________________________________ I have no internal(soft) or external modem except the N 6070 as it recognises. All set, I WVDIALed and got o/p as below :- ____________________________________________ [root@airtelgprs ~]# wvdial --> WvDial: Internet dialer version 1.54.0 --> 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*99# --> Waiting for carrier. ATDT*99# CONNECT ~[7f]}#@!}!} } }2}#}$@#}!}$}%\}"}&} }*} } g}%~ --> Carrier detected. Starting PPP immediately. --> Starting pppd at Mon Oct 2 10:38:04 2006 --> pid of pppd: 2504 --> Using interface ppp0 --> pppd: ults --> pppd: ults --> pppd: ults --> local IP address 172.28.37.241 --> pppd: ults --> remote IP address 10.6.6.6 --> pppd: ults --> primary DNS address 220.127.116.11 --> pppd: ults --> secondary DNS address 18.104.22.168 --> pppd: ults _______________________________________ Now it shows that GPRS is activated, which is also shown in the phone, the thw icons, open lock and small G within square as u ppl know when we use packet data connection. Now I should be able to browse net, but not a single page opens. What is the step I am missing ? Just see the last portion of the o/p in the post link I have given :- ___________________________________________ Carrier detected. Starting PPP immediately. --> Starting pppd at Wed Apr 26 23:11:44 2006 --> pid of pppd: 11096 --> Using interface ppp0 --> local IP address 10.33.228.142 --> remote IP address 10.6.6.6 --> primary DNS address 22.214.171.124 --> secondary DNS address 126.96.36.199 ____________________________________________ In my o/p I have this "pppd: ults" string after each line which he does not. Is only due to I use FC5 and he uses Ubuntu. Or do I need to configure pppd also. I read man pages of wvdial, pppd but could not find out where am I wrong. Also PINGed remote IP, which showed :- ________________________________________ [root@airtelgprs ~]# ping -c1 10.6.6.6 PING 10.6.6.6 (10.6.6.6) 56(84) bytes of data. From 188.8.131.52 icmp_seq=1 Time to live exceeded --- 10.6.6.6 ping statistics --- 1 packets transmitted, 0 received, +1 errors, 100% packet loss, time 0ms [root@airtelgprs ~]# _________________________________________________ --> What is "Time to live exceeded" ? Any suggestion is welcome.
