I want to read the primary and secondary dns addresses from the system and want to change it to any user given address. Is this possible through some library. An alternative approach is that I read the /etc/resolv.conf and do the changes, which is what I've done. BTW the current solution I have is for Ubuntu OS, and for now if I get ...

I have a series of python scripts with execute permissions in Linux. They are stored in SVN. If I then run svn up to update them, the overwritten files are back to 644 - ie no execute permissions for anyone. Yes I could just script it to chmod +x * afterwards, but surely there's a way to store permissions in SVN or to maintain them wh...

Very simple question, hopefully. So, in Python you can split up strings using indices as follows: >>> a="abcdefg" >>> print a[2:4] cd but how do you do this if the indices are based on variables?
