For most of the existence of my email server, i had kept it to a minimum configuration and to make sure things were configured correctly so the big players, Gmail, Hotmail, Outlook and others will deliver my email to their accounts, the only thing i had done was to make sure i had the Sender Policy Framework (SPF) record correctly set in my DNS.
This SPF entry, in the DNS, main objective was to prevent email spoofing and improve the delivery of emails from my domain.
In the little projects I am doing and using a database, sometimes I have the need to either backup and restore a database from and to the same server, but also when I want to do some development while traveling I want to have a copy of the database or databases in my laptop.
I have been having some troubles with mounting a samba shares in my Kubuntu desktop for some time. I am able to mount them but it seems the mount is not done correctly or the permissions are not fully right.
I wanted to get my head around this and started investigating it and see what was the problem, be it the way I am doing it, or the way the samba server is configured.
After having done the configuration to allow remote connections from the local network to PostgreSQL so i could development from different machines, but still using the same database so to avoid duplication of data as well duplication of PostgreSQL instances.
