yes, but is it 'basic serial UPS' or is it 'enhanced serial UPS' ? the
former do NOT use the rx/tx data of the serial port at all, they ONLY use
the serial port control signals, and they probably

serialize() takes too long when serializing to a raw vector
...a very long time:
> system.time( serialize(matrix(0, 1000, 1000), NULL) )
[1] 38.25 40.73 81.54 NA NA
> system.time( serialize(matrix(0, 2000, 2000), NULL) )
[1] 609.72 664.75 1318.57 NA NA
I was using this in Rmpi, where a clustered call returned a large matrix. However, serializing to a file or sockets is very fast for the very same matrix -- hence I wrote this function which runs much faster:
.mpi.quick.serialize <- function (object)
{
fname <- tempfile("Rmpi")
stream <- file(fname, "wb")
on.exit({
close(stream)

redirecting guest serial to file on the host
Greetings,
I have a vm to which I can access using virsh console vm1/
I'd like in addition to be able to dump the serial of the vm in to a file on the host.

New DNS-Records not aviable
hi again.
after some tests, (on my operational domain and on a new testdomain) i
detected this behavior:
on samba 4.11.6 sometimes the new DNS-records finisches on a wrong dns

the problem occurs, if more then 5 records are created with the same
name in more then one domain zone
for example:

can't delete recursive DNS entry
Due to a mistake I created a subdomain with the name of the domain itself.
In my case the domain is briesebaer.intern and I created the subdomain
briesebaer.intern.
Using DNS RSAT Tool I see under briesebaer.intern the subdomain intern and
then a recurrence of the whole domain.
That means: under intern there is briesebaer and all of the dns query
beneath.
The query shows the Name=intern

disabling serial in pxelinux
Hello from Vienna, Austria!
I'm happily using pxelinux since years. However, I encountered problems
on several machines, because they don't boot up properly with PXE. The
problem is, that there are recently some devices connected to the serial
ports of those machines. pxeboot echoes and listens to the serial
console and the output of the menu results in (silly) input back from

[PATCH OSSTEST 0/6] Support for serial logs from marilith boxes
The marilith boxes use a conserver (http://www.conserver.com/) setup for
serial access. Our installation exports the logs via http allowing us to
grab them with wget.
Sending debug keys with is handled separately via xenuse. xenuse
ultimately speaks to the conserver too but it abstracts away the IP and
port to use so this is preferred.
With these changes the correct Serial hostprop for a

[PATCH 001/001] core/serial: Add support for serial output functions.
This patch adds support for serial output functions.
It may be useful for debugging purposes since you can separate ordinary outputs from debugging dumps.
Just add "serial.h", and use either serial_print or serial_puts as you would use printf and puts respectivelly.
For QEMU, you only need to specify the option -serial stdio.
If you use another VM, find how you can redirect the serial

everything works fine and I can get output/input to the serial console. The

Unable to use more than 4 serial devices at once.
Hi All.
I'm trying to setup a guest within my hypervisor that acts as a Console

I have attempted to add the Serial Connections to a Guest, using both

detecting width overflow in serialized column with mysql
So I''ve got an ActiveRecord model pointing to a MySQL db, with an
auto-serialized column ("serialize :columnName").
Thing is, MySQL, depending on how it''s configured (like, by default),
has a bad habit of just truncating your data if it''s too wide for the
column, with no error raised. Yeah, I can probably reconfigure MySQL
and/or my AR connection to it. But

Serial Console + VGA Console
Hi,
Trying to get vga console and a serial console to both work.
I can get either one to fully work but not both.
When using serial, I do still get a login prompt on the vga,
But not all the boot up output. Seems like half to the vga
and the rest to the serial port
I added lines to /etc/inittab
# console port

And added to /etc/lilo.conf

Reduce memory peak when serializing to raw vectors
Presumably one could stream over the data twice, the first to get the size,
without storing the data. Slower but more memory efficient, unless I'm
missing something.

It is not clear if you used USB from APC UPS to USB port on the machine
side or USB - to - "serial". USB to USB with standard USB cable will work.
