panic at boot
by Emilio Lopez
Hello!
I just started fedora 16, and I get a panic message before kde starts.
I did a hard reboot (laptop power button pushed for a while) and there
are no problems.
I think a boot.log should exists, and this information should be
useful to develop team. Where is that file, and where should I send
it?
Thanks.
Emilio.

statically-built qemu-[arch] on Fedora
by Mr Dash Four
Is it possible to get/compile/build static qemu-[arch] similar to the qemu-user-static in Debian?
I am making use of binfmt_misc and need to execute statically built qemu-[arch]. Using the "standard" qemu-[arch] won't work because I am executing this in a chrooted environment where all the libraries qemu needs to link to are outside of the chroot.
I tried to use the qemu source rpm in order to build it (using the --static ./configure option), but unfortunately I can't do it - the .spec file is created in such a way that it cannot be easily adapted for building statically linked qemu executables. Any help with this would be much appreciated, thanks!

abrt isn't catching crashes
by Michael Cronenworth
I have a Gnome Shell bug[1] that I noticed was not being caught by abrt
so I tried to purposely crash other Fedora apps. They are not being
caught either. The abrt GUI doesn't seem to have any on/off switch and I
know I have not purposely disabled it (and it is running in the
background). Any ideas on why abrt isn't working?
Fedora 16 box

test local rpm file in place for consistency, size, etc.
by Skunk Worx
I have a set of .rpm files restored from backups.
They have nothing to do with my current install except they are in the
file system.
Is there a command that will sweep these (several hundred) .rpm files
and test their internal values against the file itself, in place, to
check for any problems with size / consistency / corruption?
TIA,
John

They nvidia drivers are fine. This is the error message received after
attempting to install them.
iwl4965 0000:0c:00.0: Aggregation not enabled for tid 0 because load =

Solve this mystery and the installation will go smooth.

'avc denied'
by Jackson Byers
# uname -r
2.6.35.14-103.fc14.i686.PAE
I haven't paid much attention to avc warnings.
did /.autorelabel, reboot, to see if that could stop avc.
Still see
'avc: denied' in auditlog, involving firefox, plugin-config,...

no 'file_t' seen:
[root@f14 audit]# grep file_t audit.log
[root@f14 audit]#
I have put only minimal effort into learning selinux syntax, methods.
Overwhelming, to me.
are there simple rules on how to respond to 'avc denied'?
If I do nothing?

iptables in linux
by Roger
I'm learning about iptables...
I find the same ip address sometimes 100 times or more and trying the
same user name.
After reading and applying much of the help in google I have tried and
failed to achieve a successful result.
for example: /var/log/btmp shows:
user ssh:notty Thu Nov 10 17:10 - 17:10 (00:00) hn.vtc.vn
some 30 times
user ssh:notty Thu Nov 10 17:10 - 00:20 (1+07:10) hn.vtc.vn
3 times with varying duration.
user ssh:notty Thu Nov 10 13:14 - 17:07 (03:53) 58.250.71.43
25 times with varying duration.
and similar page after page.
Is there a way to limit:
-number of log in attempts to 2,
-the duration of a log in attempt to 3 seconds or less
-the number of times a username can be tried, prefer it set at 2 and
then not again for 24 hours if it fails.
Also is there a way to DROP ip addresses after 2 attempts and not allow
that ip address for say 24 hours?
I did not find anything about this in the tutorials.
iptables does not seem difficult to grasp but I am completely stumped on
how to create tighter limits.
in part I have:
DROP tcp -- anywhere anywhere tcp dpt:ssh state NEW recent: UPDATE
seconds: 90 hit_count: 4 TTL-Match name: SSH1 side: source
And have tried seconds between 5 and 90 but find even login attempts of
2-5 minutes are not dropped.
hit_count set between 1 and 4 I still see 30+ attempts using the same
username attempt.
Help gratefully appreciated
thanks
