Multiple gmail account at same time in same web browser

Like me, most of my friends have more than one gmail accounts.Till now, to access different gmail account we had to logout from one account or install different web browser and login one account in one browser and another account in different browser. But now this problem is over. Google has come with solution. Now we can login in two gmail account in same browser at same time.

Visit to www.google.com/accounts and click the link next to"Multiple sign-in."




Select "On - Use multiple Google Accounts in the same web browser." and Save.


Now you will find dropdown arrow by the next of you account name. Click on dropdown arrow and select "Sign in to another account."


Login with other account and that's all. Now you can use multiple tab for multiple account.


No doubt this is a great feature but still there are a couple things we have to keep in mind -

1) We can use maximum two account at one time.

2) Some Google Services like Blogger and Picasa web album, don't support multiple login yet.

3) Multiple account sign-in only works on desktop browsers for now, so we can't use this feature on phone's browser.

Configure MTS Mobile Bradband on Fedora (Linux/Unix)

Recently I got a chance to use MTS wireless broadband. But like most of service providers MTS also doesn't provide support (at least to me) to use modem on linux. MTS Modem comes with dialler software for windows.But what if you want to install and use it on linux ??

I could install MTS USB Modem (Smart ZTE AC2726 (EVDO)) on Fedora 12. It should work on other distro also.

When you plug Modem linux detect it as usb CD-Drive, that's why linux network manger or wvdial doesn't finds modem and return error. To resolve you have to switch mod of usb modem.


1 - Install usb_modeswitch:

Run this command with root privilege.

#yum install usb_modeswitch                                                                                     


2- Find DefaultVendor and DefaultProduc:
To check Vendor and Product run -
#lsusb                                                                                                                         

3 -Configure switch mode:


Open /etc/usb_modeswitch.conf in your favourite editor.

Copy paste these lines...
#----------------------------------------------------------------------------------------------------------------------------------
# Smart ZTE AC2726 (EVDO)
#
DefaultVendor= 0x19d2
DefaultProduct= 0xfff5
TargetVendor= 0x19d2
TargetProduct= 0xfff1
MessageContent="5553424312345678c00000008000069f030000000000000000000000000000"
#--------------------------------------------------------------------------------------------------------------------------------
Cross check the DefaultVendor & DefaultProduct. It may be different according to your device manufacturers .

Now your usb_switchmod is ready to work. Run this command -


#usb_modeswitch -W                                                                                                 

To confirm you may run "lsusb" command again that if mode of your modem has been changed or not.  If it has been changed then you are ready to install Modem and if not, then there must be some problem. You should try again from step 1.


4 - Install Modem:

Run wvdialconf command to install modem.

#wvdialconf                                                                                                                

5 - Configure Modem
Edit "/etc/wvdialconf"
#gedit /etc/wvdialconf                                                                                                

Configuration (wvdialconf) files should look like -

#-----------------------------------------------------------------------------------------------------------------
[Dialer Defaults]
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = Analog Modem
Phone = #777
ISDN = 0
Username = internet@internet.mtsindia.in
Init1 = ATZ
Password = MTS
Modem = /dev/ttyUSB0
Baud = 9600
Stupid Mode = yes
#-------------------------------------------------------------------------------------------------------------------

Save and exit.


5 - To autodetect DNS every time you connect to modem run this command-

#echo "PREDNS=yes                                                                                                 
  DEFROUTE=yes">/etc/sysconfig/network-scripts/ifcfg-                                           

Its done. You are ready to use MTS Modem.

6 - To connect to your modem open terminal and run with root privilege

#wvdial                                                                                                                       

To disconnect use "ctrl +c ".

Note - To run TATA Photan+ follow from step 4.
