How to connect Reliance netconnect +(Huawei EC156) in ubuntu

I tried to connect a new reliance netconnect in ubuntu…i used the usual wvdial method but it was a failure…when i tried to connect using wvdial i got the error message that /dev/ttyUSB0 does not exist…

 

 

i tried lsusb and dmesg…This were the outputs

 

 

 

 

dmesg output

 

 

on dmesg output i can see the data card is detected as cdrom device…

from lsusb output i got the product and vendor id of the data card 12d1:1505

cd  /etc/usb_modeswitch.d

Create a new config file named 12d1:1505

copy and paste the following content to the file

DefaultVendor= 0x12d1 
DefaultProduct=0x1505
MessageContent="55534243123456780000000000000011062000000100000000000000000000"

Save the file..Then issue the following command from /etc/usb_modeswitch.d

sudo usb_modeswitch -I -W -c 12d1\:1505

you can see the device get detected and can see a description like this

USB description data (for identification)

-> Run lsusb to note any changes. Bye.

After this try to connect using normal wvdial method or if its is configured it may connect automatically or try a restart it will fix it

Happy Hacking……. 🙂

edit the /etc/apache2/httpd.cong

$sudo vim /etc/apache2/httpd.conf

usually it will be blank…add the following to httpd.conf

ServerName localhost

if httpd.conf contains some data then add at the top like this…

ServerName localhost
<Directory /var/www>
Options Indexes Includes FollowSymLinks MultiViews
#AllowOverride AuthConfig
AllowOverride all
Order allow,deny
Allow from all
</Directory>

Now restart apache the problem is fixed 🙂

$sudo /etc/init.d/apache2 restart
