Hey everybody, I am just newbie at Python. I wanted to write a script in Python to change DNS.

But I learned that resolv.conf is read-only file, after writing that code. Because I took that error: IOError: [Errno 13] Permission denied: ‘/etc/resolv.conf’

myFile= open("/etc/resolv.conf", "w")

Then, I made a little search and found os.chmode() and I wrote a new line to remove all privileges of resolv.conf which is:

os.chmod("/etc/resolv.conf", 0777)

But now I’m taking that error: IOError: [Errno 13] Permission denied: ‘/etc/resolv.conf’

I can’t get over this question and I’m waiting for your advices.

Thank you.

    /etc/resolv.conf is typically owned by root. Unless your script is run in such a way that it has root privileges, it won’t be able to change the file.
