Xen 3.4.1-rc7 network problem (vif/tap)
Hi,
I''m now blocked for 2 days on getting the network to work in my domU. Here is
the problem :
The domU refuses to start when a vif is configured. It''s just staying paused
for about 1m40s, then the xm create command line give back with an
"Error: Device 0 (vif) could not be connected. Hotplug scripts not working.",

data(eurodist) and PCA ??
If I perform PCA on the 'eurodist' data, should I get an accurate
geographic layout of the cities with biplot?
(barring inversions, i.e. their is no way to define north.. but you get
the idea...)
I have a complex distance matrix, and I am thinking about how to cluster
it and how to visualize the quality of the resulting clusters.
If I could 'see' the clusters in space I could

bwplot puts the bars in the wrong place
Dear R-Help,
With the attached data set, I am still getting incorrect bwplots
> xyplot(gdf$tt~gdf$OnHour |gdf$Runway, data=gdf) # Is correct
> bwplot(gdf$tt~gdf$OnHour |gdf$Runway, data=gdf, horizontal=FALSE) #
Puts the boxes on the wrong x-axis values

What is happening?

Using the output of strsplit
I successfully combined my data frames, and am now on my next hurdle.
I had combined the data and quarter, and used tapply to count the
entries for each unique date/quarter pair.
ar= tapply(ewrgnd$gw, list(ewrgnd$dq), sum) #for each date/quarter
combination sums the gw (which are all 1)
dq=row.names(ar)

But I need to split them back into the separate date and quarter. So I

How to select a row from one dataframe that is "close" to a row in another dataframe
I have two data frames of flight data, but they have very different
numbers of rows. They come from different sources, so the data are not
identical.

Looking for a SSMTP alternative
Hello all, since the default repositories (base, updates, addons,
extras) don't have a package for SSMTP I'm looking for another small
and simple MTA.
What do you suggest? Should I just stick with Exim?
Thanks for reading,

syslog question
I have a 64bit centos 5.2 system. My router supports sending logs to a
syslog server, so I was hoping to send them to my centos box so they are
easier to keep an eye on.
I've been googling for howto's etc, but I didn't think syslog would be
that difficult. Do I need to use syslog-ng or can I use the syslog
that's installed with centos 5.2?
Any suggestions or guidance?
Thanks,

Xen and bonding on Centos 5.2
Hi folks,
I am stuck with a weird phenomenon.
I have set up two servers as xen servers with bonded interfaces (mode 1).
The bond interface works fine on both servers as long as xen is not used.
When using xen's network-bridge script (with netdev=bond0), one server
works fine without problems, and the other starts upping and downing the
slave interfaces of the bond in a very fast manner

How to manipulate tables
I am sorry to be bothering the list so much.
I made a table of counts of flight arrivals by hour:
cnts=tapply(Arrival4,list(Hour),table). There are up to 15 arrivals in a
bin.
> cnts

$`1`

3 2 2 1
$`2`
1 3
2 2

My first problem is how to get this table filled in with the 0 slots.
