Semi-OT: very weird vi behaviour
This is weird. As in, *deeply* weird.
I ssh as root from one box to another (there are keys involved), and I go
to vi a file, such as
# line 1 #
# line 2 #
# line 3
# line 4
And what I see in vi is
# line 3
# line 4
BUT, if I scroll the cursor over each line with the arrow key... I see all
four lines. I've also looked at another file, and same thing. Just checked
it out on the server I

Intel VT-d Support
Hello all,
please tell me, how can I be sure that
my Xen installation is built with Intel VT-d support?
Something like
xm info | grep -i KEY-REGULAR-EXPRESSION
xm dmesg | grep -i KEY-REGULAR-EXPRESSION
What line I should look for?
And if it''s really built with it,
how can I be sure, that Xen has successfully
initialized VT-d hardware?

how many people still use NIS?
Hello listmates,
I have discovered a very strange SFTP problem which I can not connect to
anything but NIS thus far. See here:
http://www.linuxquestions.org/questions/linux-server-73/sftp-seems-to-fail-for-nis-accounts-under-openssh-5-x-816020/
http://readlist.com/lists/suse.com/suse-linux-e/38/193419.html
Hence the question: is NIS (YP) still in use much anywhere for
authentication?
Thanks.

Disabling user switching in CentOS 6
Installing CentOS 6 on a lab full of workstations, and I want to disable
fast user switching. With CentOS 5, I simply made sure that the
"user_switch_enabled" entry in
/etc/gconf/schemas/gnome-screensaver.schemas was set to false. However,
that doesn't work with CentOS 6.
I've found various proposed solutions to this issue, such as

Getting confirmation for power button
Using CentOS 5.8:
Currently on my workstations, when I press the power button the computer
immediately does a 'shutdown -h now' (per /etc/acpid/events/power.conf).
Is there a way to change it so that a confirmation dialog comes up, rather
than an immediate shutdown?
I assume that I am going to need to change that power.conf file to tell
some program that the power button's been

Insert the second CD of an install
Using CentOS 5.5 x86_64.
I am trying to install software that comes on two discs. I can start the
install just fine, but when it comes to taking out the first disc and
putting in the second, the system won't let me eject it.
I remember reading something on the internet once about something needing to
be enabled to allow this to work, but I can't find it now. Does anybody have
a clue as

updating 5.6 but not going to 6.0
I'm confused as to how to install updates for CentOS 5.6 without upgrading
to 6.0. When I do a "yum check-updates", the new *-release packages for
6.0 are listed, so I don't think I want to do a simply "yum update".
Is there a way to update 5.6 without going to 6.0?

restricting access to an NIS netgroup
I am using CentOS 5.7. I have an /etc/security/access.conf file which has
the following:
+ : root : LOCAL
+ : @mynetgroup : ALL
- : ALL : ALL
I thought this is supposed to restrict access to the system to only root
and the accounts in the mynetgroup netgroup; however, anyone NIS account
is still able to login. It appears that the access.conf is being ignored
completely, so I'm thinking

Well, if I just run audit2why again, it always tells me the same thing. However, I have now discovered that if I unset allow_ypbind, and then reset it to 1, audit2why then says

setting up auto logout in CentOS 6
I would like to have my lab workstations logout a session after the person has been idle for a certain period of time. After some searching on the web, I got into

and set the default value of max_idle_action to ?forced-logout?:

Script to monitor websites and generate RSS feed when they change
Looking for the above. I have found sites where you can register the sites you are interested in - as well as yourself - but I would rather run something myself on my server to monitor websites etc which do not have RSS-feeds.
Does anyone use something like this?

Best practices for copying lots of files machine-to-machine
An entire filesystem (~180g) needs to be copied from one local linux
machine to another. Since both systems are on the same local subnet,
there's no need for encryption.
I've done this sort of thing before a few times in the past in different
ways, but wanted to get input from others on what's worked best for them.
One consideration is that the source filesystem contains quite a

CUPS not generating a printcap file
According to all of the documentation I can find, an /etc/printcap file
(or whatever filename is specified with the Printcap directive) is
generated by cupsd ever time a printer is added or removed. On all of my
CentOS 6.7 systems, this is NOT happening. I can restart cups and add or
remove printers over and over and it still doesn't generate the printcap
file.
Is this a known issue, or is
