[gentoo-user] amavisd-new needed for spam-only filtering with SpamAsssassin?

2011-11-15 Thread Pandu Poluan
I'm setting up my company's email server (Postfix), and I want to use
SpamAssassin to weed out the spam messages.

Do I need to use amavisd-new? Or can I just pipe Postfix to
SpamAssassin directly without using amavisd-new?

Rgds,

Nice! Thanks! I've been using nvidia-settings which is GUI based and
nice to look at but not something you can save as text. Nice to have
another option.

Note that the 465 has two IDs but nvidia-smi doesn't show temps for

Re: [gentoo-user] {OT} Are push backups flawed?

2011-11-15 Thread Michael Orlitzky
On 11/14/11 20:54, Grant wrote:

 If you're intent on making a two-stage pull work; you can do it by
 creating a 'backups' user on your servers, and then using filesystem
 ACLs to grant backups+r to every file/directory you want to back up.
 That way, an attacker on the backup server can't decide to peruse the
 rest of your stuff.
 
 I like that.  So use ACLs to grant access to the backups instead of
 using ownership/permissions so that the ownership/permissions stay
 intact.  I've never used ACLs.  Do they override
 ownership/permissions?  In other words, if the ACL specifies backups+r
 to a file owned by root that is chmod 700, backups can read it
 anyway?

Yup, they work like Windows ACLs if you've used those. You can grant one
user read permission without affecting anything else.

The '700' mode doesn't really make sense anymore after you apply an
ACL.. the whole permissions-as-bits concept gets highly convoluted[1]
but if you just want to add read access for one user it's easy.

You can use setfacl to add permissions, and double-check with getfacl
that they do what you think they do. The examples in `man setfacl` are
pretty easy to understand.


 The easiest method, though, is to just add a third stage. Either move
 the backups on the backup server to another directory after the backup
 job completes, or sync/burn/whatever them off-site. In this case the
 backup server can't access anything you don't give it, and the
 individual servers can't trash their backed-up data.
 
 I don't see how that could work in an automated fashion.  Could you
 give me an example?

We do push backups to one server, backup1, every night. Then, every day,
backup1 syncs to another server, backup2. The individuals servers have
no access to backup2, and it's physically separate from backup1.

I make physical, removable, backups of backup2 every once in a while,
but not as often as I should.

True. Unfortunately, I don't have 'exotic' hardware to test mdev against,
and USB pass-through is not yet supported on XenServer 5.6 (which I'm using

I can try it inside VirtualBox on my Windows workstation though. Will that

[gentoo-user] Upgrading gcc: both 4.4 and 4.5 needed?

2011-11-15 Thread Jarry

Hi,
today I upgraded gcc from 4.4.5 to the last stable version
4.5.3-r1. I followed Gentoo GCC Upgrade Guide:

# emerge -uav gcc
# gcc-config 2
# env-update  source /etc/profile
# emerge --oneshot libtool

# emerge --depclean
# revdep-rebuild

But at the and I noticed gcc 4.4 has not been unmerged
and my world file is somehow larger. To my surprise,
it contains these lines:

sys-devel/gcc
sys-devel/gcc:4.4

I did full backup before, so I compared world-file before
and after gcc-upgrade just to find out, these two lines
have been really inserted now, during gcc-upgrade. And my
question is: what does it mean? Does my system need now
both gcc 4.4 and 4.5? Why is actually gcc in world-file,
when it is part of system?

Because your forgot the -1 / --oneshot flag when manually upgrading gcc.
However, in system, multiple gcc slots do  not exist, so if you need gcc:4.4 for
backwards compatibility or gcc:4.6 for forwards compatibility, it'll show up in
your world file.

 I'm pretty much clueless in python so can't interpret the messages -
 hopefully someone more knowledgeable will chime in.
 
'Broken pipe' just means the remote closed the connection. It's a pretty
standard error in this context, which the server should handle.

A process normally gets a SIGPIPE which will by default terminate it, which 
is what you want if you have a pipeline'd command whose output is no longer 
required. An example would be checking there is at least one matching file 
somewhere in a directory hierarchy with:
  read -d '' f  (find /base/dir -type f -name 'foo*' -print0)
  [[ $f ]] || echo 'no foo* files'

-- find will terminate after the first filename has been read.

In this case, signal(SIGPIPE, SIG_IGN) or the equivalent has been called,
which gives EPIPE instead; a process ignoring the signal is supposed to deal 
with the error. So I'd say it's a bug.

I think you are correct.  When you use the -u option, it shouldn't add 
anything to the world file.  Than again, weird things happen from time 
to time.  Take the two entries out and see what emerge says to a emerge 
-uavDN world which should catch about everything.  Then see what -a 
--depclean says.  If it tries to remove the older version then that may 
be why it was added.

Hi, Gentoo.

My gcc now fails to work.

I upgraded it earlier on (I think) after doing an emerge --sync.  I

of them.

lipgmp has a lot to do with my problem.  After my last emerge -uND
world, I think libgmp was upgraded.  At any rate the messages on the
screen directed me to

revdep-rebuild --library /usr/libt64/libgmp.so.3

, which I did.  They then informed me I could safely delete libgmp.so.3,
which I also did.  :-(

Now, when I attempt gcc on the command line, I get the error:

/usr/libexec/gcc/x86_64-pc-linux-gnu/4.4.5/cc1: error while loading
shared libraries: libgmp.so.3: cannot open shared object file: No

symlink it to the later version, or copy the lib over from another
system.

Then rebuild dev-libs/gmp and dont delete the lib!

I got bitten by this but only on one system - the file is supplied by
the later ebuild so I dont know why it asks to delete it.  Was in the
middle of a major snafu when it bit so didnt bug report it - should
have.

Check to make sure a gcc is selected:

gcc-config -l

Sometimes if a old version is removed the link is sort of left dangling

 Nope, not here. Besides, F5 really is set to Refresh. I also cannot find

Thanks for checking this.  Are you using std.vcf or the Kmail 'Personal

The kaddressbook that was hosed with pressing F5 was in std.vcf.  I'm not sure 
I understand the difference between these two akonadi resources, other than 
that the std.vcf is the old KDE format under .kde4/share/apps/kabc/std.vcf, 
while the Personal Contacts seems to be stored under .local.share/akonadi/ ).

I'll be using my existing water cooling setup, so no need to worry about
that. However, after some research, I've decided to stick with Intel and
orders an i7 2600k today. I wasn't sure whether it was worth the extra
over the i5, but knew I would only regret it the first time I had to wait
for something. I rationalised the cost by getting only 8GB of RAM, but
leaving the slots free for another 8GB should I feel the need for it.

 I just start to compare. 6 cores, yep, sounds good for both

The Intel chips are only four cores, but appear to give a lot more
bang-per-core, especially with the i7's hyperthreading.

The old GCC version does not get removed.  This is a good thing just in

If it works OK, you can manually unmerge the old version:

Before doing that, however, make sure the new one has been activated

I did some more testing, the lock occurs also when booting from CD so I

Re: [gentoo-user] swapping processor problem

 I have two gentoo boxes, X has an ASUS M2NPV-VM with AMD64 3500+ CPU, Y
 has a AMD64 X2 5600+ CPU. Since I need more juice on X I thought I could
 swap CPUs.

 After updating X's BIOS the system with the 'new' CPU boots up to the
 MythTv screen with no error but does not respond to the USB keyboard nor
 to the remote control keypresses. More precisely:

 - keyboard is fine at grub boot, I can select up and down or edit the
 entries
 - keyboard is no longer responsive at the init scripts start (when you
 can press 'I' to select services)

 My first thought was that X (and Y) WERE compiled with '-march=native'
 GCC flag and maybe the 5600+ does not execute properly the 3500+ code.
 But a quick search on wikipedia shows that 5600+ has a superset of the
 3500+ so I should have problems putting the 3500+ in the Y box, not
 vice-versa.

 Any suggestions?

Play with your BIOS settings. Look for things like legacy USB support.
Also, double-check that all the relevant USB drivers (UHCI, EHCI,
XHCI, HID, etc) are either built-into the kernel, or are loaded as
modules. Consider rebuilding your kernel.

Just because one processor has a superset of the instructions of the
other doesn't mean there may not be other compatibilities. Some time
back, a thread on here discussed how to find out what -march=native
becomes, in terms of -march and a bunch of other parameters. I've
noticed parameters like cache line sizes and cache sizes, among a
couple others. I imagine a bungling of, e.g., cache line sizes could
break code that has heavy dependency on data locality and/or memory
models; it might have broken your USB drivers, for example.

But, really, I think BIOS settings and driver presence are the more
likely culprit.

sys-devel/gcc: Add support for the framework for loop optimizations
based on a polyhedral intermediate representation

So, a new, experimental optimization model and framework inside your
compiler. If it's specifically for optimizing on loops, I'll venture a
guess it's going to be mostly effective for graphics libraries and
apps. I've got some slightly riskier educated guesses on how it works
and what some numeric side effects and consequences might be, but they
scare me, so I think I'll leave it to someone who actually knows more
about it...

I don't think it was a software issue because the same lock happened
also booting from a live-CD. I ended up swapping the motherboards, now
live-CD boots fine but I need a new kernel.

The march=native thread looks interesting, do you remember the subject
line so I can search it in the archives?

Here it is:

gcc -Q --help=target  -march=native

I agree tho that checking those BIOS setting is a good start.  If that fails, 
boot a CD or something, chroot in, do a emerge -e system.  Maybe make some 
corrections to the kernel then try booting.  Oh, I'd rebuild the input drivers 
to, mouse and keyboard.  Check the USE flags too.  I'm not sure what all 
options they have.
