Java Access in Firefox
by Stephen Morris
Hi,
I am currently using Firefox 49.0a1 on both Linux and Windows and
on both systems Firefox will not activate Java, this has been the case
for several versions of Firefox. I have to java plugin in the
appropriate mozilla directories, but Firefox will still not use it. I
have also checked about:config and there appears to be no java entries
in there whatsoever.
Does anyone know any way to activate Java in these versions of Firefox?
regards,
Steve

Maybe run xev and see what keystrokes it's actually sending.

by maderios
Hi
Is there a way to install wordpress on F23 and no http/apache2
dependency? Nginx is installed on my system, I don't want apache2.
Thanks

keyboard with a numeric keypad which does not work in Fedora
by Chris Murphy
Hi,
I have a laptop with its own keyboard which lacks a keypad, and a USB
keyboard with a keypad. I plug in the keyboard and the keypad doesn't
work anywhere in Fedora. So... how do I make that work?
I don't care for it to work in the console, I only care if it works in
GNOME Calculator really.
Thanks,

Entropy from TPM of Fedora 23?
by D. Hugh Redelmeier
I have a server that I want to use to test Libreswan VPN software. This
requires a lot of entropy (for random number generation).
Unfortunately, the box, a Dell, has a processor with no RdRand
instruction. But it does have a TPM 1.2 module, and that is supposed to
be able to generate entropy.
I don't know how to get the TPM to feed entropy to the Linux kernel RNG.
Is there a cookbook explaining how to do this?
I installed Trousers to handle the TPM device. That provides "tcsd"
the daemon that manages "Trusted Computing resources" (including TPM).
I installed tpm_tools.
I initialized the TPM with
tpm_takeownership -y -z
rngd is the daemon that is supposed to feed hardware entropy to the
kernel RNG. It is part of the rng-tools package. I would have
thought that enabling the TPM would allow rngd to harvest entropy from
the TPM. That does not seem to be the case.
rngd can open /dev/tpm0 but cannot read from it. (This isn't obvious
since rngd's diagnostics are not very specific.)
I think that the problem is that only one thing is allowed to open the
TPM at once, and that one thing is currently something else. Probably tcsd.
Here's a closed bugzilla against RHEL7 that seems relevant:
<https://bugzilla.redhat.com/show_bug.cgi?id=921122>
My problem certainly isn't the same. tcsd seems to be running and
happy. Compare this with what Steve Grubb said in Comment 5.

[build@bluebird ~]$
(The read errors are from trying to read /dev/hwrng. The error code is for "No such device".)
Here's a run of a version of rngd that I instrumented:
[build@bluebird ~]$ sudo ./rngd -f -v -r /dev/NOTHING
Unable to open file /dev/tpm0: Device or resource busy
can't open any entropy source
Maybe RNG device modules are not loaded
[build@bluebird ~]$
-f: don't daemonize
-v: verbose
-r /dev/NOTHING: replace /dev/hwrng with a meaningless path to preven using it.
According to this old page <https://fedoraproject.org/wiki/Features/rngd_default_on>
Note that when using TPM, rngd currently conflicts with tcsd
from TrouSerS. The solution to that is a kernel module which
is probably going to be merged upstream in the 3.7 kernel, as
it unfortunately missed the 3.6 merge window; however, it is a
small patchset and it can be trivially backported. It should
be in James Morris' linux-security git tree shortly; otherwise
search for Kent Yoder on LKML.
I don't know what that module is, whether my system has it, and if so,
is it actually loaded. There are two loaded modules with tpm in their name:
tpm_tis 20480 0 - Live 0xffffffffa033b000
tpm 40960 2 tpm_tis, Live 0xffffffffa0104000
It is even possible that the TPM is being used now. Monitoring
/proc/sys/kernel/random/entropy_avail seems to show more entropy that
I observed yesterday. But it isn't enough for what I'm trying to do.

firefox javascript
by Patrick Dupre
Hello,
I just update my firefox to 46.
When I try to connect to dogpile, the javascript does not seem to
be working any more.
I use the option "activate", but it is not enough.
I am the same issue with gmx.com
What you I do ?
Thank.

using rex (rexify) soes not do a command properly...
by dcw
I use Rex to maintain remote servers. Using Rex to do a upgrade on the
remote server using the following commands does not work:
yum -y upgrade vim-X11-2:7.4.1718-1.fc22
yum -y upgrade vim-common-2:7.4.1718-1.fc22
yum -y upgrade vim-enhanced-2:7.4.1718-1.fc22
yum -y upgrade vim-minimal-2:7.4.1718-1.fc22
Rex does a sudo for each command.
Also logging in to the remote server and doing the above upgrades work as it should.
I manage remote systems with both F22 and F23 and each has the same failure.
All other upgrades are done correctly, it is just the ones related to vim that fail.
All other commands work correctly.
Any ideas on how to troubleshoot this?

FC23 Managing printers as non root users
by Javier Perez
Hi
How can I allow users to manage printers in FC23? For example if hey need
to pause/resume the printer, right now they need the admin with the root
password to do it. This is a home setting so I do not mind people doing it
(but I do mind having to go to their rescue :) )
I tried already adding them to the lp and even created a printers group but
still I get the prompt for the root user when I try to manage the print
queue
Thanks
Is there a document that describe the printing process as applied to the
FC23 environment what choices and limitations have been applied and where
to look to troubleshoot stuff?
Thanks
