I also have SELinux disabled on this particular box :(

Hand cranking it in the foreground gives a seg fault, but nothing in

The weird thing is that it was working fine until I had to do a power
cycle a couple of days ago to free up a locked serial port.
Any ideas?

Re: [SLUG] Videos in presentation software
On Thu, 2005-05-05 at 12:30 +1000, James Gregory wrote: Hi all, I need to give a presentation which will include some videos. Currently they're avi files, but I'm just as happy to make them mpeg or whatever. I ended up using the 100build of OpenOffice 2 beta. I used the instructions on this page: http://www.ucolick.org/~zingale/OOo_movies/ It worked ok but dropped a lot of frames in the first video I showed with it. Don't miss the step about altering your classpath *inside* OpenOffice; That drove me mad for quite a while. It also seems pretty fussy about what codecs it will use; but less fussy than doing the same thing in PowerPoint. Another oddity is that it behaves differently with different JDKs. Sun's 1.4 JRE opens up a new window for the video while the 1.5 one will embed the movie correctly but it only works once. Anyway, you *can* do it. I thought others here might find the information useful.

Re: [SLUG] ntpd won't start
Looking deeper into a link from one of the links I posted below :
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=151262 shows it to
be a registered bug.
An excerpt suggests the following :
ntpd randomly segfaults, compiled with the default RPM_OPT_FLAGS...
turning off exec-shield-randomize cures the segfaults
can do this by doing the following as root :
echo 0 /proc/sys/kernel/exec-shield-randomize
or to make it permanent :
add /kernel.exec-shield-randomize = /0 to //etc/sysctl.conf
/Might be worth a try - although you should note that by turning off the
randomisation of Linux memory, it is making the system less secure -
although with SELinux turned off already it's probably not that much of
an issue for that box.

Re: [SLUG] ntpd won't start
Urgh - don't know what happened in that post but the line to make it
permanent should be :
add kernel.exec-sheild-randomize = 0 to /etc/sysctl.conf
for some reason when I sent the email as plain text - thunderbird added
the slashes you see below.
Hopefully it works this time round ;)
Cheers,
Paul

Re: [SLUG] ntpd won't start
Thanks for that, it certainly worked. Now I need to look at the other
implications. :( Probably time to do some study on the /proc/sys
settings :)
