F14 AMI passwords
by Pete Zaitcev
Looking at the /etc/shadow in our official AMI ami-6e3a6a2b, I observed
that root and ec2-user have passwords. Why are they left in? I suppose
they do not hurt much, since sshd_config sets PasswordAuthentication
and PermitRootLogin to no. Still, I'm just curious what they are.
Even better, let's think in reverse: if the creator accidentially
used a real root password, can I crack any interesting servers by
cracking the root password and then applying it to bits of Fedora
infrastructure (I know it's not 3-DES anymore, but still)?

Cloud SIG Meeting on 2010/11/25 - Cancelled!
by Robyn Bergeron
Hi Folks,
I realize that not all of us celebrate US holidays, but I for one will
be stuffing my face with delicious turkey tomorrow, and then preparing
for my Friday holiday shopping blitz.
Since a good chunk of us are based in the US, I'm hereby cancelling
the regularly scheduled Cloud SIG meeting. Don't let that stop you
from meeting anyway if a bunch of people show up - anyone can use the
power of meetbot :)
I hope everyone has an excellent holiday, and for those not in the US,
I hope you enjoy the lower volume on all your mailing lists :)
See you all at *next* week's Cloud meeting! And keep those features coming :D

Broken 32-bit F14 EC2 images?
by Steven Moix
Hello,
I just tested the Fedora 14 EC2 AMIs, 32 and 64 bit and there are
visible problems...Here is a scenario where I just launch an instance,
install Apache and start it. It works on the 64-Bit box but not at all
on the 32-Bit box... On the 32-Bit box, Apache just never starts (it
hangs at Starting httpd until you hit Ctrl+C) and in any case there are
RPMDB errors...
Any clue on what's going on?

yum doesn't work on FC14
by István
Hey,
you might have came across with this:
# yum update
Config time: 0.007
Yum Version: 3.2.28
COMMAND: yum update
Installroot: /
Setting up Package Sacks
Error: Cannot retrieve repository metadata (repomd.xml) for repository:
fedora. Please verify its path and try again
I can download any repomd.xml wo/ trouble using wget and filling up the
variables in the URL by hand.
Unfortunately there is no strace installed yet so I can't just trace what is
happening. I am going to install it from rpm and see what is going on. Any
advice is welcome.

disk IO inside EC2 instance
by Denis Shaposhnikov
Hello!
I'm trying to use Fedora 14 inside EC2 instance. First I converted
instance-store AMI to ebs one. Basically it works but any program which
trying to something "heavy" with file system is eating 99% of CPU
forever. I saw it with mysql trying create privilege databases,
bacula-fd trying to backup /etc and even logwatch.

perl module install hanging on getdents64
by Simon Smith
First - thanks for getting Fedora updated on EC2! I've been using FC8 there
and FC13 (now 14) on Rackspace.
Things are working fine, except: on the EC2 Fedora 14 image I've installed,
I can't install perl modules. I've tried with several, and when I do "perl
Makefile.PL", it just hangs at "Checking if your kit is complete...". When
I do an strace, it seems like its hanging on getdents64 (last few lines at
bottom of this email).
Note: on my Rackspace Fedora 14 instance, I do not see this behavior and am
able to install perl Modules OK.
Any tips or pointers on where to go, debugging-wise, would be much
appreciated.
Thanks!
Simon
