Welcome to jnvilo.com

Soooo... somehow you found your way to jnvilo.com. This site contains linux stuff and other things I put online. Mostly notes, documentation and other things I want to remember or have access to wherever I am. I put them up online in the hope that they may be usefull to others. The site is also a sort of web development toy for me and technology test so to speak. The website is often rewritten in whatever framework I happen to be playing around at the time. Currently it is written in python using the excellent Django framework.

I want what so many flavours of Linux promised and never delivered – worktime productivity with sexiness and speed rolled into one overpriced silver package with backlit keys."[ posted by some other jason on the net ]   ....[read more]

Allow NFS traffic through firewall on Centos 6 and Redhat 6

Nov. 14, 2011, 6:20 a.m.
NFS is a protocol that uses more than one port and actually also uses both TCP and UDP. Another issue on the standard NFS setup is that NFS does not use standard static ports unless told to do so.
