sun java plugin problem on Fedora 14

[Dr. Michael J. Chudobiak]

Hopefully this will save other people time: if you can't get the Sun jre 
java plugin to work after upgrading from F13 to F14, try:

setsebool allow_execstack 1

Bad code on Sun's part.

OK, this works too and is narrower in scope:

chcon -t execmem_exec_t /usr/lib64/firefox-3.6/firefox

It's worth checking the Firefox context too.

Allowing execstack everywhere isn't such a great idea.

Whoops, there should be a "-P" in there to make the change permanent.

It is labelled correctly (java_exec_t), but I still needed "setsebool -P 
allow_execstack 1".

[mjc@xena ~]$ ls -Z /opt/jre1.6.0_22/bin/java
-rwxr-xr-x. root root system_u:object_r:java_exec_t:s0 
/opt/jre1.6.0_22/bin/java

what does ls --lcontext /blah/blah/java say?

It should be

-rwxr-xr-x. 1 system_u:object_r:java_exec_t:s0 root root 36548 Oct 13 13:53
/usr/lib/jvm/jre-1.6.0-openjdk/bin/java*

The "java_exec_t" is important.  I think "execmem_exec_t" would also
work.

I have had same intermittent prolems in F13, and I still get them once 
in a while.
Problem is gvfs. Sometimes it just fails to mount the media's storage.

Hi Jason! Humm, in Fedora 13/14 you can work with any kind of USB performing
normal tasks,
try another port and plug your usb again to start copyng/reading files from
it.

Some programs like UnetBootin need to mount the usb trough the console:

1.- fdisk -lu

2.- mount -t vfat /dev/sdc1 /mnt (Here you have to put the correct device
you want to mount acording to the fdisk list)

And that's all... Verify your USB is OK with Gparted.

Good Luck!

Also occurs on some emails if you use Thunderbird, so the bad code isn't
only on Sun's part...Mozilla has some, too.

Can't mount USB drive in F14

[Jason E. High]

I just installed F14 yesterday, and I'm coming from Ubuntu.  In Ubuntu,
whenever I plugged in a thumb drive or connected my Motorola Droid, it
would automatically mount.

In F14, it tries to mount but just an error pops up and tells me that
I'm 'Not Authorized.'

It lists the drive in the Places menu, and I've tried adding my user
accounts to various groups, including root, with no success.  I've seen
a few threads online with similar complaints, but have yet to come
across any solutions.

Help?
