CIDR to Netmask conversion with Python (convert short netmask to long, dotted format)

When you write scripts dealing with setting up or analyzing network interfaces you will eventually run into the task of converting a netmask from one format into another.

POSTFIX - GMAIL & HOTMAIL ERROR

Posted 09-03-2010 at 12:48 AM by maxshortte1982

Hi,

I am new to Linux and I have recently installed Postfix on my centOS system. When sending e-mails to gmail or hotmail my messages automatically get redirected to junk mail or dont get delivered at all. Does anyone know why this is happening? I am also having issue with receiving e-mails from gmail/hotmail accounts.


I have read on one website that this issue could be cause by my IP address being blacklisted OR could be caused by a dynamic IP. Is this true?...

Whooopeeeeeeeee!!! Ten minutes ago the postman delivered the long-awaited parcel. Now I'm going to be as patient installing it, as I have been waiting for it to arrive. Going to read all the instructions here, and here carefully, before I do anything else.

Todays miracles

Today God relieved a brother from his pkgsrc affliction after invoking the cvs prayer. In a twinkling of an eye, God's holy angels delivered cleansed make files into his /usr/ports/ subdirectory.

Praise the Lord!
