what is the process number of a "running application" ?
by Angelo Moreschini
Hi,
I would like to know the process number of an application that actually is
running (Netbeans in my case), with the purpose to kill it (when is froze).
But am am not able to know this process number..
- In the window of gnome-system-monitor the name "netbeans" isn't.
- The command line : "ps aux | grep netbeans", give me a full page of
references..
Could I know a simple way to have this information ?
Thank you
Regards

Blocking POODLE
by Matthew Saltzman
SSLLabs reports a couple of servers of mine have SSL v3 enabled and are
vulnerable to POODLE. I followed instructions for Apache httpd at
https://scotthelme.co.uk/sslv3-goes-to-the-dogs-poodle-kills-off-protocol/, but that does not seem to cure the problem. SSLLabs still reports the servers as vulnerable. Does anyone know what I'm missing?
The server also runs Trac and Subversion servers and a separate vhost
runs Jenkins. Does something special need to be done for those
services?
(These are, in fact, RHEL 7 servers running httpd-2.2.15-39.el6.x86_64,
but I hope someone here will know what's going on.)
Thanks in advance.

Thanks for your response, Mr. Hayes.
Mr. Sean, please download and check if "timeout" is still present with built RTL8153 module from REALTEK site, as Mr. Hayes proposed.

fedora 20 to 21
by Patrick Dupre
Hello,
I wish to update a fedora 20 installation to 21 by using a DVD.
Is it possible?
Actually, I burn a DVD bootable server fedora 21, but I did not find
the option update.
When I go to installation
then System, I can select my hard drive and manually partitioning
I can see the installed system (/ /boot and swap)
I can install fedora 21 but not on the same partition (I can reuse /boot)
I have to install it on a new /
I cannot have a mounting point / on the old fedora /
This seems to indicate that I cannot upgrade from this DVD.
How do you update a fedora 20 without network?
Thank.

kded issue
by Martín Marqués
Hi all,
I have a laptop with Fedora 20 (IIRC I had F19 and upgraded like 6 or 7
months ago to F20) and everything was working great til a few weeks ago.
The problem is that every now and then, when I try to sent the laptop to
sleep, by closing the top or pressing Fn+F4, it doesn't full finish the
sleep process.
Let me explain this last thing:
It takes some time for the laptop to sleep, and when you open the top and
press any key it wakes up but the screen isn't blocked and kded is draining
the CPU (I mean kded is hanged). This means that most kde applications
won't work (NM won't authenticate, for example)
The only way to get back is to kill -9 kded (yes, kill -15 doesn't kill
it), and start it again.
I'm going to install debugging symbols now so that next time I can gdb on
the process.
Anyway, has anybody else experienced this?

not able of booting into rescue mode
by Angelo Moreschini
Hi,
I'm not able of booting fedora 20 into rescue mode.
In the manuals is wrote:
Once you have booted, using one of the described methods, (booting from a
boot CD-ROM or DVD, ..., ...)
add the keyword rescue as a kernel parameter.
For example, for an x86 system, type the following command at the
installation boot prompt:
linux rescue
etc ...............
*but I can not see any prompt* where I can type
that command.
When I boot from my disk of installation (fedora live 20)
I get (only) the following menu:
-
start fedora live in basic graphic mode;
- test this media and start fedora live
- run a boot memory test
- boot from local drive
- return to main menu
( I opt for the first option (of course) and so by the installation of the
OS)
nothing to do with a recovery procedure .....
What am I doing wrong ?
Regards
Thank you

Mediacast to TV

I have a smart TV (Sony Bravia) and can use Android Cast Screen from my

Old Kernel Modules Directories not Cleaned up
by Stephen Morris
Hi,
DNF is currently configured to keep 3 kernel versions, consequently
when I exceed that number of kernels it automatically uninstalls the
oldest kernel, which I don't have any issues with, but what I do have an
issue with is when these uninstalls are done it does not clean up the
/lib/modules directories, they are left lying around. I had to delete a
dozen of these directories this morning manually, why are these not
removed when the associated kernels are removed? I didn't check what was
in these directories, but I do have the nvidia and virtualbox kernel
drivers installed as well, is it possible the removal of these when the
associated kernel is removed is not cleaning up properly?
regards,
Steve

Re: fedora 21 booting error with 3.17 & 3.18 kernels-SOLVED- still need info
by Paul Cartwright
I finally let the boot sequence error out, took about 5 minutes. I got
this line:
Dracut-initqueue[283] Warning: Cancelling resume operation. device not
found.
then the next line showed the UUID, ending in c063. That was the OLD
swap partition. I rebuilt the swap partition, did the swapon, and added
that UUID to /etc/fstab. Still errored out with same error. I removed
the 3.18.3-201 kernel & headers & module, reinstalled them, and now it
works. where is that old swap info kept, if not in /etc/fstab?? I
grepped for c063 in /boot and found entries in System.map-3.18.3-201...
but I am not sure it was the actual swap partition.
