how to connect to internet via mobile in rhel4

i am trying to connect to internet via mobile in rhel 4. i searched for the procedures in net and i found one which was given below. i did exactly how he explained and even scceeded to connect to the internet. the problem is in my mobile a symbol showing connection to internet is displayed but when i tried to connect from the browser of pc it is not connecting.even when i am disconnecting it is showing the amount of time it is connected to internet. any body please suggest the solution.

i just copied the text given below and paste in etc/wvdial.conf.
and run the command given.

For this you will have to copy the following as save it as /etc/wvdial.conf using the root account:

Modem = /dev/rfcomm0
Baud = 230400
SetVolume = 0
DialCommand = ATDT
FlowControl = Hardware(CRTSCTS)

Modem = /dev/ttyACM0
Baud = 230400
SetVolume = 0
DialCommand = ATDT
FlowControl = Hardware(CRTSCTS)

[Dialer GPRS]
Username = 1
Password = 1
Phone = *99***1#
Mode = 1
Inherits = Modem0

[Dialer DATA]
Username = <>
Password = <>
Phone = *99***1#
Mode = 1
Inherits = Modem1

[Dialer Defaults]
Modem = /dev/rfcomm0
Baud = 230400
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = AT+CGDCONT=1,"IP",""
ISDN = 0
Modem Type = Analog Modem
Area Code =
Phone = *99***1#
Username = <>
Password = <>
Ask Password = 0
Dial Command = ATDT
Stupid Mode = 1
Compuserve = 0
Force Address =
Idle Seconds = 3600
DialMessage1 =
DialMessage2 =
ISDN = 0
Auto DNS = 1

It will ask for the root password. Enter it and it should connect.

For dialing via data cable, you will have to pass the command:
sudo wvdial DATA

in the linux world there are many programs that use the pppd program. Point To Point Protocol Daemon wvdial uses it gnome uses gpppd kde uses kpppd wvdial is a comand line program I find using kpppd works fine just plug the usb device in and type lusb and to find out what com port it is using like this /dev/ttyACM0 dype dmesg and look for it.
if you are not used to command line programs try the gui ones and configure your device.

when you do
sudo wvdial DATA
make sure you have that part filled in.
Dialer DATA]
Username = <> <--------------------
Password = <> <-----------------
Phone = *99***1# <-----------------------
Mode = 1
Inherits = Modem1

The best option would be to connect your mobile via data cable and using the internet of the sim card services.

why do you want to connect the older rhel4 server to a mobil phone via a copper telephone line using 56k dial up ??
or is this using a usb cable ?
please give us a better discription of what it is you need to do and WHY you need to do it using the older rhel 4 operating system
( ps the older rhel4 might not have any support for new hardware -- to old)
the current red hat os is RHEL6

Welcome to LQ, krisbadsg

Interesting Q. I see you tried unsuccessfully to use "Code:" blocks, you can find more info about them at the BB code link near the bottom of this page.

John VV's points about RHEL4 being old & giving us an overview of your goals are good.

If you CAN connect to the internet (wvdial shows connected or whatever) try putting the following in /etc/resolv.conf


by the way, if your phone company routes all traffic through a wap proxy, you might need to set the proxy in your browser to the one your service provider uses.

by the way, i think username and password should be left blank. do you have balance in your phone? can you surf the net from your phone? gprs is slow (!) try opening a lightweight site (

I'm using two ways to connect my Crunchbang (debian squeeze) laptop to internet using android phone:

1) laptop > USB > android > mobile data
Using EasyTether app
Pros: No need for root
Cons: Free version of EasyTether doesn't support https, only http. Full version supports https.

2) laptop > WiFi > android > mobile data

Using WiFi Barnacle Tether app:
Pros: No additional software for laptop needed - using existing WiFi drivers, supports https, the app is free on the market
Cons: Needs android rooting
