ganesha error ?
Hi,
I got these errors 3 times since I'm testing gluster with nfs-ganesha. The clients are php apps and when this happen, clients got strange php session error. Below, the first error only happen once but other errors happen every time a clients try to create a new session file. To make php apps work again, I had to restart the client. Do you have an idea of what's happening here ?

aggredating date data
I tried a date by date forecast of a time series and it seems to be
too wild. How can I aggregate the date into weeks or months as
required?
Thanks.
The input looks like
ID datadate("YYYY-MM-DD") value_for_day

-- ------ --------
and I want to be able to change it to

problem packaging S4 class that contains a slot of jobjRef class
Hello,
I'm trying to package some source files that link R to a broker using
a Java API and the rJava package. I am successful doing the connection
and operate on it using my R code. I would like to package the files and
release the package.
I created some S4 classes to hold several Java objects. I use WinXP and R
2.7.1. I've searched RSeek and the Wiki for help, but could not find a

reading csv files
the csv files are downloaded from a database and it looks like some
character fields contain the CR-LF sequence within them.
This causes R to see a new record/row and the number of rows it sees
is different (usually higher) from the number of rows actually
extracted.
Any suggestions?
Thanks.

2FA for Dovecot
I block all my email ports except 25 from countries where I am not going to be sending or receiving email. I also block many datacenters, but blocking Digital Ocean, Vultur and AWS will get you 90%of the way there. You will need to use 587, that is no auth on 25. Again no blocking on 25, just block the other email ports.
I get maybe one attempt to log into my email account a week. Yeah not as

Outputting csv file from dataframe with columns in a particular order
I have a dataframe with columns "ID",'date","estimate","actual" (but
not necessarily in that order - I do a merge somewhere and that
somehow messes up the order of the columns).
How can I output it to a csv file with the columns in the order that I
want?
Thanks.

OpenSSH3.0p1/PAM/Sol8
Hi there,
I just tried out OpenSSH3.0p1 running on Solaris 8 with PAM (--with-PAM).
The problem was mentioned some time ago and is still there :-(
When a password is expired you are prompted to change it now, enter your
login password and after doing so you are instantly disconnected. I think
this is a problem with PAM and not SSH, but how can I get a solution on this
?

R splits character fields in a csv file
I download a csv extract from a database and use read.csv to read it
from R and when there are large character fields with embedded blanks,
slashes etc. - R often sees one line as two lines (or more).
I verfied with readLines that an embedded blank in a character field
causes a spurious new line to be seen.
I am sure this problem has beem seen before - and would appreciate any
