Installing FreeBSD 9.1 64bit on Windows 8 pro Hyper-V

FreeBSD installs without any issues if you add Legacy Network Adapter, instead of standard one in VM settings before install. I used ISO file 64bit  FreeBSD-9.1-RELEASE-amd64-dvd1. I assume the 32bit would have the same procedure.

update: out of box there are no Integration Services (heartbeat, time, reboot, etc..), but there is a patch that MS is trying to incorporate into FreeBSD / refer to

the patch is sort of ready for 8.2 but not yet for 9.1, anyway this is what you can do to try to add hyper-v support in 9.1, run:

# pkg_add -r git
# cd /usr
# git clone
# cd /usr/freebsd-head
# make buildworld
# make buildkernel KERNCONF=HYPERV_VM

for 8.3 or 8.2 follow the instruction here

The hyper-v  on Windows 8 pro will complain that network adapter hn0 is in degraded mode and that integration service upgrade required.

freebsd-update error

Freebsd-update error:

root@FreeBSD:/ # freebsd-update fetch
Looking up mirrors... 3 mirrors found.
Fetching metadata signature for 9.1-RELEASE from done.
Fetching metadata index... done.
Inspecting system... done.
Preparing to download files... done.

The following files will be added as part of updating to 9.1-RELEASE-p2:

root@FreeBSD:/ # freebsd-update install
Installing updates...install: ///usr/src/crypto/openssl/ssl/s3_cbc.c: No such file or directory

to solve it, just create that missing folder - mkdir -p /usr/src/crypto/openssl/ssl

This happens if you did not install sources tree.

Nessus 5.2

Quite exciting new features of Nessus 5.2, such as including screenshots in the reports(as example if RDP port was open - screen of RDP login), full IPv6 support and other...!

Nice looking HTML5 interface, flash also available if you miss it.

Note that:

"With the release of Nessus 5, all Nessus server configuration is managed via the GUI. The nessusd.conf file is deprecated. In addition, proxy settings, subscription feed registration, and offline updates are managed via the GUI" :(

To set update of plugins to everyday as example, go to Configuration - Advanced - verify auto_update - yes and auto_update_delay - 24 (this are the hours).  This way it seems there is no need to cron anything. Anyway you can  start update manually via GUI or by the script (FreeBSD example: /usr/local/nessus/sbin/nessus-update-plugins )

iBooks issue in offline mode

There is an issue with iBooks in 6.1.3 on iPad2. When iPad is in offline mode (disconnected from iTunes server) and you try to click "Store", it will complain that iTunes store is not available, but will not let you to go back to iBooks. The only way to read you books again is to reboot iPad.

Sharepoint SQL db recovery model: full vs simple

There is certain issue in the logic of recovery model of SP: the recommendation is to use full recovery,  as it keeps transaction log data,  instead of simple. However,  if you use  Sharepoint backup the log never gets flushed.  And so it keeps growing,  until you run sql backup log command. But since you already did full db backup,   the backup log file is actually not needed and can be deleted.  Work of Sisyphus... The way out is to use simple mode, although it not recommended.  Anyway talk to you dba...

IT governance: doing the right things and doing things right

Easy to remember principles of governance are ilustrated by Gartner:

IT governance addresses two major topics: demand governance (“doing the right things”)
and supply-side governance (“doing things right”).

PS: for more staff for IT governance refer to an elaier post and

PPS: there is an interesting analysis on centralised vs decentalised model - refer to Figure 5 in this document

Intel chipset Z77 vs X79

As anyone who is trying to get more than 32GB on a home lab PC, I asked the same question: What motherboard do I need to obtain more than 32 GB RAM. The answer is not so simple, as the popular Z77 and H77 are not supporting RAM over 32GB. At this moment the only choice is X79.  The drawback is that you need LGA 2011 socket processor and that fact is that Z77 is more recent than X79. So, no 3rd generation  I7 support for this one. Waiting for Intel to tic-tac further and hopefully further price drops...

So from timing and price point of view, anyone should be happy with Z77 (or H77 locked) and quite affordable CPU I7-3770K (or I7-3700 locked) = limited to 32GB RAM and 4/8 cores.

If you are ready to wait until June 2013, then you may save some money on current lineup since a new one is getting ready: 4th generation of Intel CPU and Z87, H87, etc. chipsets - refer to

Why you want to buy Samsung or Intel SSD disks?

One of the reasons is the fact that these companies produce NAND chips themselves (

and they have a theoretical right to select the best quality batches to be used in their own final products.
