My understanding was that the primary limitation of running docker on other OSs was the Linux Network containers that made it possible. (Certainly for Macs).
Recently Microsoft announced a beta of a Ubuntu linux user mode running natively on Windows 10. This can run binaries compiled in ELF format on Windows (unlike cygwin which requires a compilation.)
My question is: Can you run Docker natively on the new Windows 10 (Ubuntu) bash userspace?
I've just update my Apache server to Apache/2.4.6 which is running under Ubuntu 13.04. I used to have a vhost file that had the following:
<Directory "/home/john/development/foobar/web">
AllowOverride All
</Directory>
But when I ran that I got a "Forbidden. You don't have permission to access /"
After doing a little bit of googling I found out that to get my site working again I needed to add the following line "Require all granted" so that my vhost looked like this:
<Directory "/home/john/development/foobar/web">
AllowOverride All
Require all granted
</Directory>
I want to know if this is "safe" and does not bring in any security issues. I read on Apache's page that this "mimics the functionality the was previously provided by the 'Allow from all' and 'Deny from all' directives. This provider can take one of two arguments which are 'granted' or 'denied'. The following examples will grant or deny access to all requests."
But it didn't say if this was a security issue of some sort or why we now have to do it when in the past you did not have to.
I run a particular program on linux which sometimes crashes. If you open it quickly after that, it listens on socket 49201 instead of 49200 as it did the first time. netstat reveals that 49200 is in a TIME_WAIT state.
Is there a program you can run to immediately force that socket move out of the TIME_WAIT state?
I have been poking around Amazon EC2, and am a little confused on some of the terminology. Specifically with regard to AMI, snapshots and volumes, and an EBS
Please correct me if I am wrong, or fill in any serious gaps in my following statements:
An AMI (Amazon Machine Image) is a full 'disk' capture of an operating system and configuration. When you launch an instance, you launch it from an AMI
An EBS (Elastic Block Storage) is a way to persist the state of any modifications you made once booting from a given AMI. In my mind, this is sort of like a diff on the final state of your instance vs the AMI.
A snapshot is ... well, I'm not sure. I can only assume it is a snapshot of a specific instance, but it is not clear to me how this differs from the state stored in an EBS. How is a snapshot different from creating an EBS AMI from an existing instance?
A volume is ... it would seem mounted disk space into which an AMI/EBS pair is loaded? I'm not sure on this one either. I can see (from the AWS Console) that you can create a volume from a snapshot, and that you can attach/detach volumes, but it isn't clear to me why or when you would do that.
Is there a way to view the members of an Active Directory group if you aren't a domain admin and can't log into to a domain controller?
