  • 772

I've try

vahid@DEMON:~$ ifconfig 
eth0      Link encap:Ethernet  
...

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
...

ppp0      Link encap:Point-to-Point Protocol  
...

vboxnet0  Link encap:Ethernet  
...

wlan0     Link encap:Ethernet  
...

Then

vahid@DEMON:~$ vnstat -i ppp0

and got this error:Error: Unable to read database "/var/lib/vnstat/ppp0". Then

vahid@DEMON:~$ vnstat -u  -i ppp0

And got these error: Error: Unable to read database "/var/lib/vnstat/ppp0". Error: Unable to write database "/var/lib/vnstat/ppp0".

Could you please help me?

    When you run vnstat -u you will need to use sudo

    so do the below command with sudo 

     sudo vnstat -u  -i ppp0

    If all goes ok it should create a database.

    Now configure /etc/vnstat.conf to monitor ppp0 interface 

    Interface "ppp0"

    and then restart vnstat 

    /etc/init.d/vnstat restart
