device p3p1 entered promiscuous
by Paolo Galtieri
Today I noticed for the first time that I'm getting the following messages
in /var/log/messages on one of my F19 systems.
Jul 23 10:55:03 terrapin kernel: [ 122.662105] device p3p1 entered
promiscuous mode
Jul 23 10:55:08 terrapin kernel: [ 127.669312] device p3p1 left
promiscuous mode
These messages occur every 5 minutes and last 5 seconds.
I have 2 other F19 systems running on the same network that do not show
these messages. The system that is seeing this problem is a Dell Inspiron
7537.
Anyone seen something similar?
I have attached the output of ps axlw in case someone can see which process
might be doing this.
This problem seems to have started on July 6 based on looking at the old
logs
[pgaltieri@terrapin Downloads]$ sudo grep promisc
/var/log/messages-20140629 | wc -l
27
[pgaltieri@terrapin Downloads]$ sudo grep promisc
/var/log/messages-20140706 | wc -l
21
[pgaltieri@terrapin Downloads]$ sudo grep promisc
/var/log/messages-20140713 | wc -l
1752
[pgaltieri@terrapin Downloads]$ sudo grep promisc
/var/log/messages-20140720 | wc -l
2843
Any help is appreciated.

partitioning
by Dustin Kempter
Hi all, I am an SA in training and ive been reading a lot about the
importance of separating out your workspace/server into separate
partitions such as /, /data, /home, /ftp, /usr, /boot vs dividing it
into just a /, /boot, /data. and it seems that doing it how Ive been
reading about with more partitions is more secure but what about when
one partition becomes full? isnt that more of a problem vs one big /data
partition where that is not an issue? what would you guys say the best
solution would be? also read that you want to have twice as much swap as
RAM and that dividing swap into 2 partitions helps with performance. is
this true?
thanks

CPU/Memory
by Patrick Dupre
Hello,
I have 2 machines running fedora 20, one from 2007 with a dual processor
and 3 Go, and a recent one (2013) with a quad processor an 8 Go.
But it is a lot more convenient to use the old machine!!!
The recent one is always busy, 4 processors running
53.1 55.9 /usr/bin/python -Es /usr/sbin/setroublesootd -f
and the memory becomes full quickly requiring swapping!!
8 Go for the OS and firefox! Something is wrong.
Should I kill setroublesootd?
What is wrong? I cannot see.
Thank.

wlan0 not working - F20 arm
by Robert Moskowitz
I have this old Trendnet usb 802.11bg adapter plugged into my server.
It is not showing in Network manager (see prior message) so I am trying
via command lines:
# ifconfig wlan0 up
# iwlist wlan0 scan
wlan0 No scan results
Don't tell me that, my notebook is connected wirelessly and I can see
b/g support in the APs here.
and
# ifconfig wlan0

NetworkManager not running? F20 arm xfce

In my vnc connection to my server, the xfce system bar's network manager
tells me:
Networking disabled (when I place the mouse over the network icon)
Network Manager not running (when I click on the network icon, and this
text is grey)
Yet in my ssh session to the server:

vncserver not starting today

OK. New day, new testing. I can get IPv4 setup quickly and routing
right. Yeah me (with a little help from my friends I got by)!
So I go to start vncserver where I was up to yesterday where I got the

Problems with Fedora 20
by Roger
Couple of things seem to have gone awry.
I think Ubuntu update to 14.04 has messed around with Fedora 20 grub
boot because booting now takes for ever and defaults to Ctrl D to
Continue or root password for maintenance, then takes 30-50 seconds to boot.
2nd, With the latest updates and kernel-3.15.5-200.fc20.x86_64
something seems wrong. The machine used to be quite fast but now is very
slow.
Any processes like opening and deleting emails, screen refresh,
opening or closing files is very slow and the hard drive is working
overtime with every mouse click or key press.
CPUs are running at 20-50%, memory runs at 85%, temp directory is
running overtime.
Whereas performing the same in ubuntu 14.04, 386 memory runs around 35%,
cpu's 20-50%, no hard drive temp used at all, and emails open and delete
immediately.
I have cleaned repositories, removed unused files and software in both
setups, run sudo yum autoclean, sudo yum clean packages. top shows
nothing untoward.
I am running 3.15.4-200.fc20.x86_64 for this email and the system seems
to be better but the hard drive works overtime with each change.
kernel-3.14.8-200.fc20.x86_6 produces inode errors and boot fails.
There is a command to rebuild grub boot but I don't remember the
details, can someone please point me to how this should be done.
What should I look for as to why the system is not operating as before.
Help much appreciated
thanks

Figuring out a headless server's zeroconf addr
by Robert Moskowitz
I have a headless system that I cannot connect to. So I was thinking to
put a direct connection to it and my notebook. Both ethernets would use
the zeroconf (169.254.0.0/16) addresses. I could then use fping
fping -g 169.254.0.0/16
And SHOULD be able to get its address, and then SSH into the box.
Any other thoughts? I can't get to the box to recable it and reboot it
(as that is the only way I can figure out for it to readdress eth0)
until this evening.

Memory
by Patrick Dupre
Hello,
Is it normal that /usr/bin/python -Es /usr/sbin/setroublehootd -f (2 shells)
consumes 8 GO of RAM (i.e. 49% and 46% of the total)?
Thank.
