Tried to connect to internet through Wvdial in Ubuntu 10.04 unable to get connection
 

Dear All


I tired to connect my Huawei USB modem through wvdial in ubuntu 10.04. Wvdial was installed. I configured the wvdial according to the details given in the website below.

What to do next to get connected to mobile broadband Internet


Dalfish

Can you please paste the output of the following command?
ls -al /usr/sbin/pppd

The permission of this file should be like this.

$ ls -al /usr/sbin/pppd
-rwsr-xr-- 1 root dip 273312 2010-03-07 09:29 /usr/sbin/pppd

If you see difference, please execute the following command and then run "wvdial"

chmod 4754 /usr/sbin/pppd

Blue print thank you The output you requested is exactly the same

-rwsr-xr-- 1 root dip 273312 2010-03-07 09:29 /usr/sbin/pppd

i executed the command


chmod 4754 /usr/sbin/pppd
chmod: changing permissions of `/usr/sbin/pppd': Operation not permitted

what to do next

I am stuck with huawei 1553 and reading through to see a salvation... but here I can give you some rapid help. You should run "sudo chmod 4754 /usr/sbin/pppd" to get rid with the "Operation not permitted" as not being root you can not alter files at "/usr/sbin/pppd" and
sudo goes around this if you are registred at sudoers. Otherwise (very bad) use "su" and
turn administrator.

This is probably not your modem number but look at the configs......HERE

Thank you Tarcisio I have typed the following as per user request in the terminal


sudo chmod 4754 /usr/sbin/pppd


But still

The output is the same as above

This might explain your permissions problem...Here
