I'd like to try out EC2 and so I'd like to launch a cheap spot instance to play around with. The hi1.4xlarge is supposed to have 2 SSDs, but I can't find them on the machine. I've launched the instance with ami-58a3cf68 image, which is a 64-bit paravirtual Ubuntu 12.04 instance storage image.

During the setup phase, it says the disks will be /dev/sdb ad /dev/sdc.

enter image description here

However, when I log onto the machine, these disks don't appear to exist:

$ ls /dev/sdb
ls: cannot access /dev/sdb: No such file or directory

I'm trying to setup the logentries service. If a log entry has a token in it then I would like to send it to api.logentries.com:10000. The token is a guid in the format aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee.

Right now I'm doing:

# If there's a logentries token then send it directly to logentries 
:msg, regex, ".*[a-z0-9]{8}-[a-z0-9]{4}-[a-z0-9]{4}-[a-z0-9]{4}-[a-z0-9]{12}.*"
& @@api.logentries.com:10000

I checked the rsyslog debug logs and my regex is not matching, but I can't figure out why or how to fix it:

5245.961161378:7fb79b514700: Filter: check for property 'msg' (value ' fb1c507f-2ede-4d7f-a140-2bd8d56e133 - application - [play-akka.actor.default-dispatcher-1] - Found user: 4fb11ea5e4b00a1aeebe2800') regex '.*[a-z0-9]{8}-[a-z0-9]{4}-[a-z0-9]{4}-[a-z0-9]{4}-[a-z0-9]{12}.*': FALSE

I'm trying to setup passwordless SSH access.

My username is bmccann, so in /etc/ssh/sshd_config I added:

PermitRootLogin no
PasswordAuthentication no
AllowUsers bmccann nx

I ran ssh-keygen on the client and put ~/.ssh/id_rsa.pub from the client into ~/.ssh/authorized_keys on the server.

I can now login with no password using the ssh command. However, I can no longer access the machine via NX as long as /etc/ssh/sshd_config has "PasswordAuthentication no".

Server error logs:

$ grep NX /var/log/messages
Feb 11 01:25:51 bmccann-htpc NXSERVER-3.4.0-12[23552]: ERROR: Failed authentication. NXSsh exit status is:255 'NXNssUserManager::auth'
Feb 11 01:25:51 bmccann-htpc NXSERVER-3.4.0-12[23552]: Failed SSHd authentication for user 'bmccann', to '127.0.0.1', port '22': 'NX> 204 Authentication failed.\n ' 'NXNssUserManager::auth'
Feb 11 01:25:51 bmccann-htpc NXSERVER-3.4.0-12[23552]: ERROR: Error while trying to authenticate user:bmccann. NXNssUserManager::auth returned 255 'NXShell::handler_login'
Feb 11 01:25:51 bmccann-htpc NXSERVER-3.4.0-12[23552]: ERROR: failed 'sshd authentication' for user 'bmccann' from '108.29.137.64'. NXShell::handler_login NXShell 373

What do I need to do to restore my NX access? Is there something I need to setup in the NX client so that it no longer asks me for a password?

I'm just setting up Hamachi, but having some trouble. I have a Hamachi instance running on my Linux machine at home and I'm trying to connect to the Samba share on it via my Windows laptop. The Hamachi UI on my laptop shows a 5.x.x.x IP address with a blue star next to it. It also shows a 5.x.x.x IP address for my Linux machine with a green star next to it. I can't access any of the network services or SSH to my Linux machine. If I try pinging it from the Hamachi UI that also fails. Is it expected that the pinging would fail since I don't have a web server running on my Linux machine? What else can I do to troubleshoot? Could I be having problems because I'm behind a firewall at my workplace?
