FreeBSD: Jails (3) - VIMAGE

In order to create a jail with its own virtual network stack, with its own network interfaces, addresses, routing table and so on, the kernel must be compiled with the VIMAGE option for this to be available.

FreeBSD: Jails (2)

Here is another way to create a jail:

FreeBSD: Jails (1)

Here is the simplest way that I found to create a jail:

FreeBSD: pkg / installing nano

I've already installed additional software from the ports collection, now I'll try to use pkg. From the man page, the pkg is a package management tool. The difference is that you can use the FreeBSD Ports Collection for installing from source, and packages for installing from pre-built binaries.

- Upgrade the pkg
pkg upgrade (answer yes for all questions, if any)

- Installing nano text editor
pkg install nano

FreeBSD: Update and Upgrade

Updating, or applying security patches, is quite straightforward:

freebsd-update fetch
freebsd-update install

The first command will determine if any outstanding patches are available, and if so, will list the files that will be modified if the patches are applied. The second command will apply the patches.

Upgrades are divided in two types: minor and major upgrades:
- Upgrades from one minor version of FreeBSD to another, like from FreeBSD 10.1 to FreeBSD 10.2, are called minor version upgrades;
- Upgraded from one major version to another, like from FreeBSD 9.X to FreeBSD 10.X, are called major version upgrades.
Both types of upgrades can be performed by providing freebsd-update with a release version target:

freebsd-update -r 10.2-RELEASE upgrade

Chinese New Year Holiday: Orlando

I've been to Orlando, Florida in January 1999, I was 16 at that time. I still remember the old airplane that took the group from GRU (São Paulo) to MCO (Orlando) with a quick stop in Trinidad and Tobago for refuel. The Orlando trip was based on four main Disney parks, Universal studios (at that time the Island of Adventure was under construction or about to open, I guess), Bush Garden and Sea World. At the end we went to Miami by bus, mainly for shopping, and then came back to São Paulo.

Now I had the opportunity to go back to Florida with my family, at this time in February 2016 during Chinese New Year break. The weather is about the same (cold!!!) and now the journey started from HKG (Hong Kong) with stops in SFO (San Francisco) in the outward journey, and ORD (Chicago) when returning.
