Controlling dovecot caching decisions
Hello,
It looks like the "mail_always_cache_fields" and "mail_never_cache_fields"
can be used to control dovecot's caching decisions. I cannot seem to find
any documentation regarding how these fields should be used.
What are acceptable values for these fields? I am quite new to this so any
help would be much appreciated.
Regards,
Siva

Bursty writes - why?
I have a 24 x 1TB system being used as an NFS file server. Seagate SAS disks connected via an LSI 9211-8i SAS controller, disk layout 2 x 11 disk RAIDZ2 + 2 spares. I am using 2 x DDR Drive X1s as the ZIL. When we write anything to it, the writes are always very bursty like this:
ool 488K 20.0T 0 0 0 0
xpool 488K 20.0T 0 0 0 0

Inadequate error checking in rsync 2.5.5
I'm using rsync to mirror files from a Windows XP machine mounted via smbfs. Apparently I have something configured wrong as I get a "permisson denied" error accessing some of the files on the smbfs mount with cp, od, etc. However, rsync produces no error messages on these files. It happily creates files in the target directory that are the right size, but filled with null bytes.

SSD partitioned into multiple L2ARC read cache
What would the performance impact be of splitting up a 64 GB SSD into four
partitions of 16 GB each versus having the entire SSD dedicated to each
pool?

Jackknife in Logistic Regression
Dear R friends
I´m interested into apply a Jackknife analysis to in order to quantify the
uncertainty of my coefficients estimated by the logistic regression. I´m
using a glm(family=’binomial’) because my independent variable is in 0 - 1
format.
My dataset has 76000 obs, and I´m using 7 independent variables plus an
offset. The idea involves to split the data in let’s say 5 random subsets

Multistage Sampling
Dear WizaRds, dear Thomas,
First of all, I want to tell you how grateful I am for all your
support. I wish I will be able to help others along one day the same way
you do. Thank you so much. I am struggling with a multistage sampling
design:

Meet Me Configuration
I am trying to configure MeetMe so that external callers can enter the
conference rooms after an IVR menu. I have created Conf rooms for all
internal Ext's with a prefix of 8. When I call into the system from my
vonage trunck the IVR picks up but will not let me dial a conf room. It
tells me it is a invalid extension.
Can anyone help with a sample conf on this?
Thanks,

RE: Newbee question (hot phone numbers)
Just dropping a note about hot-desking
I believe hot-desking requires hot phone numbers. These hot phone #
should not be connected to physical phones but rather to a database
entry from where the physical phone(s) is(are) retrieved.
Users should be able to modify (securely) their own database record.
I'm currently trying to understand Bluetooth and the Norwood Bluetooth
initiative.

Priv Sep SSH has / as CWD
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hi,
This may or may not be a bug. However, it is DEFINITELY NOT how I would
expect and want to see sshd work!
If you run lsof against sshd on a privilege separated user, it shows
that sshd's CWD is /. I would hope that the CWD would be at a minimum
/var/empty/sshd and I would really have thought it would be something

rsync 2.6.0 (final) released
I've released version 2.6.0 of rsync. Two important things to note
in the new release:
1. The default remote shell is now "ssh" unless you tell
the configure you want to use something else.
2. Some bug fixes in the include/exclude code, while making
things work properly, have resulted in some user-visible
changes for certain wildcard strings. Read the

$HOME/.shosts and setegid()
Hello,
The ssh deamon from OpenSSH_2.5.2p2 first does a seteuid(uid) and then
stat($HOME/.shosts) to check whether a .shosts file is there. This
seems to be a problem when homedirectories are only accessible "by
group permission"; for example in the following (as I guess quite
common) case:
drwxr-x--- root mygroup 512 Apr 10 12:09 mygroup
And my personal homedirectory would now
