F14 AMI passwords
by Pete Zaitcev 01 Dec '10

01 Dec '10

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)? -- Pete

Cloud SIG Meeting on 2010/11/25 - Cancelled!
by Robyn Bergeron 24 Nov '10

24 Nov '10

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 -Robyn

Broken 32-bit F14 EC2 images?
by Steven Moix 18 Nov '10

18 Nov '10

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? ************ 32-Bit: ami-669f680f ************ Appliance: fedora-14 appliance 1.0 Hostname: domU-12-31-39-03-81-83 IP Address: 10.249.130.113 [ec2-user@domU-12-31-39-03-81-83 ~]$ sudo yum install httpd ...usual yum stuff...

yum doesn't work on FC14
by István 16 Nov '10

16 Nov '10

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. # uname -a Linux ip-5 2.6.35.6-48.fc14.x86_64 #1 SMP Fri Oct 22 15:36:08 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux Regard, Istvan -- the sun shines for all http://blog.l1x.me

disk IO inside EC2 instance
by Denis Shaposhnikov 15 Nov '10

15 Nov '10

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 12 Nov '10

12 Nov '10

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!
