FreeNAS 0.7 live: fix the annoying IPTOS_LOWDELAY error

If you are tired of this error in log:

smbd[16703]: [2009/12/13 10:26:43, 0] lib/util_sock.c:set_socket_options(237)
smbd[16703]: Unknown socket option IPTOS_LOWDELAY

you have to do a little trick on /etc/rc.dsamba to remove “IPTOS_LOWDELAY” in socket options, doing this (you can add those lines to a script and make it launched after boot, like explained in this article):

sed 's/IPTOS_LOWDELAY//' /etc/rc.d/samba > /etc/rc.d/samba2
mv /etc/rc.d/samba2 /etc/rc.d/samba
chmod +x /etc/rc.d/samba
/etc/rc.d/samba restart

That’s all.

FreeNAS 0.7 live: how to install packages (like mldonkey)

If you want to install FreeBSD packages on FreeNAS live you have to “move” your /usr/local directory where you have more space.
This is what you have to do to install mldonkey, for example:
Create a directory local inside your storage:
mkdir /data/local
now copy the content of the current local directory to the new one:
cp -a /usr/local/ /data/local/
and link it in it’s new place, after removing the old one:
rm -r /usr/local
ln -s /data/local /usr/local

Now your /usr/local dir have more spaces and you can install whatever you want. I’ve installed mldonkey with
pkg_add -r
(since FreeNAS it’s based on FreeBSD 7.2) then i’ve moved my home dir to the storage doing the same things above.
NB: mldonkey needs, you can download it from here and you have to copy it at boot time in /usr/lib.
To have all the jobs done at startup you’ve to create a simple script (and put it in your storage, i’ve created mine in /data dir):

rm -r /usr/local
ln -s /data/local /usr/local
rm -r /usr/home/simplex
ln -s /data/simplex /usr/home/simplex
cp /data/ /usr/lib

Now chmod +x the script and tell FreeNAS to launch it after boot.
Go to System->Advanced->Command scripts and add the command sh /data/ or whatever you’ve called it and set type PostInit.
I’ve also added screen to launch mlnet inside it.
Enjoy mldonkey on FreeNAS!

United States Patent 7,617,530: Rights elevator. Microsoft patent sudo. Or only the gui to have administrator privileges?

This is ridiculous but at the same time so sad. USPTO accepted the request, and now Microsoft have the patent for that is common know as ‘sudo’. Or only for the gui?
Reading from the patent:

This invention relates to elevating a computer user’s rights.
And after:
Rights elevator 114 is capable of elevating a user’s rights; including permitting a task that is prohibited by a current user’s account or the controlled-access application. The rights elevator may enable a user to elevate his rights from that of a limited-rights account, such as a standard user (e.g., non-admin) account, to a higher-rights account, such as an administrator account. The rights elevator may enable the user to elevate his or her rights through user interface 116, such as by presenting a name of a higher-rights account and enabling submission of an authenticator for that account.
Does Microsoft invented this? Really? I don’t think so.
From the webpage of sudo:
Sudo was first conceived and implemented by Bob Coggeshall and Cliff Spencer around 1980 at the Department of Computer Science at SUNY/Buffalo. It ran on a VAX-11/750 running 4.1BSD. An updated version, credited to Phil Betchel, Cliff Spencer, Gretchen Phillips, John LoVerso and Don Gworek, was posted to the net.sources Usenet newsgroup in December of 1985.

Now, i don’t get if this patent is strictly related to the user interface that permit this temporary “privilege escalation” or if they really have the patent for the concept behind sudo, plus a graphic interface.
This patents are getting ridiculous, really.
