Unfortunately AWS has been severely neglecting meaningful IPv6 support. Their "solution", if you can call it that, is to throw a non-VPC ELB in front of your application. For many reasons that is a non-tenable solution for many use cases. As a stopgap fix, the tactic I've seen used by several organizations is to stand up an IPv6-capable VPS with another ...

It's 50 user per AP, but there's no way for you to load-balance who connects to what AP. Just because you have 3APs doesn't mean you'll be able to have 150 concurrent users. That's only in an ideal world. You really should invest in APs that can auto-loadbalance and do smart channel select. Depending on how many concurrent users you plan on having, you ...

You can do it with PF as well. However, rdr only accepts incoming packets. Thus, you have to first route those packets to lo0, then add a rdr-rule there (which will catch them as they will be routed in from "somewhere") to send them to your local SSH-server. The order is necessarily: rdr stuff, then filter stuff (like pass), but chronologically the 2nd rule ...

We're just trying to bring our Macs into the fold here. My original plan was to use Backup Exec's Mac agent. Then I found out that the agent doesn't support 10.9, or even 10.8. So if you're keeping the OS up-to-date, that's out. I've heard legend tell that the next SP will get it up to speed, but I'm not holding my breath. It has been a few years, but ...

Acronis supports Macs and a centralized backup server. Symantec also supports Macs and has a centralized appliance. There's also Retrospect, a long-time established Mac backup package that also appears to support a local backup server. I'm sure there are more. (I've intentionally excluded cloud services.) Of course, the way we're using Acronis (for ...

I used to use CrashPlan at a previous job to back up a couple of hundred Mac laptops, a few Windows VMs, and even a couple of Linux servers. They have a cloud based solution, but we used the on-premise server (I think they've since renamed it to CrashPlan ProE) and it was rock solid. I liked it enough that I use their cloud consumer solution to back up all ...

You can create IPv6 records for your ELB by prepending ipv6. to your ELB's public hostname. Hostnames and IPs redacted due to it being a customer environment - this is in the eu-west-1 region in a non-default VPC. craig@zeus:~$ dig AAAA ipv6.blah-0000000000.eu-west-1.elb.amazonaws.com +short 2a01:xxx:3::xxx:3314 2a01:xxx:3::xxx:ff14 2a01:xxx:3::xxx:7f20 ...

Apple used to supply their own version of Java, but have moved away from that in favour of donating the code to the OpenJDK project. The fundamental reason is that Java is portable, but the JVM isn't - especially components that are about the platform, such as sound, file-system, and GUI components. What Apple did was write the OS-X parts of the JVM, and ...

It's a legitimate address range - if Apple's using it as a default address for their routers, then they're doing it wrong. ARIN confirms that the whole 6.0.0.0/8 range is assigned to "USAISC", and if you take a look at a BGP looking glass, you'll see that 6.3.0.0/18 is being actively routed on the internet by AS668, which is assigned to the US DoD.

I'm afraid not sorry. That said the vast majority of iOS apps are either 100% compatible between v5 and v6 or need a simple recompile with the XCode 4.5 to be ready, and dev releases of v6 have been available for 4-months+. So it's a shame that your devs didn't put the effort into fixing the root-issue, it would've save you having to go out of your way to ...

Apple Remote Desktop's Copy Items & Install Packages features don't have the specific filtering ability to do that, but you can do it in two easy steps with a Smart List: Click the "+" button in the lower-left corner of the Remote Desktop window and select "New Smart List..." Name the new "Smart List" where "Mac OS Version" is "greater than" version "10....

I believe the "extend wireless" option is for extending the wireless using wireless :-) When extending over cable, Apple seem instead to call it "Roaming type network". So reset your units and start over. Connect each unit using cable and create a wireless network on each one using exactly the same SSID, encryption, password etc. The only special one ...

I just had to handle this. Finding the backup In my case, mysql lives in /usr/local/mysql/ (where the last part is actually a symlink to the current installed version of mysql). It actually does correctly back up the files, and the whole structure exists on the backup. But for some reason, even if you navigate to the correct local path in finder, if you ...

The router isn't providing DNS. Your Macs can all see each other because they use mDNS(Bonjour) for local name resolution. You can install and configure Ahavi on your Ubuntu machine if you want it to work the same way, or you can set up an actual DNS server.

The JAMF Casper Suite of products is the industry leader for OS X deployment and management. Think of it as being very similar in function to SCCM for Windows machines. That said, SCCM 2012 and later can deploy applications to OS X in a very similar way to how it deploys applications to Windows clients. If you're already leveraging SCCM, you can extend it ...

No: It is not possible to PXE boot any arbitrary OS. Let me explain why: After the first stage of booting a PXE enabled hardware has loaded some code of the OS into the memory of the target computer, this code has to "know" that the boot process should continue over network and not from some local media. So every type of OS you need to be able to boot ...

I think what you're looking for is sw_vers. You can create a script that calls it and parses the output. If it matches (or doesn't match) then call the package installer. Sample output: Marks-MacBook-Pro:~ mark$ sw_vers ProductName: Mac OS X ProductVersion: 10.8.2 BuildVersion: 12C60

Internal SATA connections are required to work with cables up to 3.3 Feet, yes. eSATA are required to work up to 6.6 (but simply adding a bracket doesn't change what the original port is capable of). That said it's been my experience that most ports are simply built for the higher spec as the costs are negligible and the chips are more flexible that way. I ...

A couple of options, in order of hack-ness: Install OS X Server ($50). Expensive, as you have to dedicate a mac to it, but you do get a lot of other stuff in the box. Install FreeNAS, which is appliance-like, and now supports Time Machine (see http://forums.freenas.org/archive/index.php/t-1157.html which indicates that as of August, support was in the ...

I use Backblaze for many of my clients and on all of my machines (well, all the Win and OSX anyway - no support for anything else)- I can recommend them highly. The downsides are that the inital backup can take a while and it can be cumbersome to do a complete restore (they will overnight a drive for something like $200, but it can take time to prepare it), ...

You probably want to look into implementing Open Directory, or setting up an Active Directory forest, and integrating your Macs into that. Which you choose should probably be determined by whether you're going to be an all-Mac shop or not. If you plan on just having Macs as being the only devices you want to manage centrally, use Open Directory. If not, ...

You can certainly do this, but unless you script it (see below) there's no single-step solution. The basic steps are going to be: Bind the Mac to AD. Delete the local account, but leave the home folder alone. This can be done from the command line with dscl, or in System Preferences -> Users & Groups (just be sure to select "Don't change the home folder"...

The Xserve Setup Guide states that all the DIMMs must be identical. Therefore, you cannot mix different sizes of DIMMs in the same Xserve. (Note that identical means that they must have the same specifications for size, speed, and timings. They don't necessarily have to be the same brand, but using RAM that Apple didn't sell you may invalidate the support ...

In us-east I use an IPv6 tunnel broker to provide an IPv6 tunnel which allows the instance to be addressed directly using an IPv6 address. Since the tunnel broker's point of presence is cross-connected to Amazon locally, this adds only about 1ms of latency. The down side is that, to get IPv6 to other instances in the subnet, you have to route it yourself (e....

Came across an interesting article (published 1 December 2016). https://aws.amazon.com/about-aws/whats-new/2016/12/announcing-internet-protocol-version-6-support-for-ec2-instances-in-amazon-virtual-private-cloud/ You can enable IPv6 on VPC's in the "Ohio" region.

Buy a NAS system supporting Time Machine. Many SOHO class devices do. Set up a system with MacOS Server and use the built-in TM feature. A Linux server with Netatalk installed should work as well. This is what is used internally by the aforementioned NAS devices in many cases.

This could be an MTU issue... I'm assuming you have an intermediate device between the ASA firewall and your Apple wireless devices. Your Cisco ASA is not a wireless access point. Please check that intermediate device and provide more information about it... There's nothing inherent to the use of a Cisco ASA 5505 that would impact or prevent good ...

The UEFI in modern Macs does not support PXE as an older BIOS does. Macs netboot using BSDP (Boot Server Discovery Protocol), not PXE. There are extensions to the isc-dhcpd (the package snoweagle mentioned) that support BSDP. To take advantage of this and have only one boot server for your windows and macs you'd need to get away from WDS (my understanding ...

I'm using PXELinux so I'm not sure if this will help. I was getting a headache setting all the flags etc to boot winpe from files. So I told it to forward the iso instead. I'm not familiar with macs. If there is something like a pe disk you could theoretically send the pe disk to the mac and theoretically have it establish either a nfs or smb share, then ...

If I were you, I'd use network home folders over NFS or AFP and have a standardized image built from something like Deploy Studio or Apple's built-in deployment solution. When a laptop fails, all of the data and user state is safe on your server (which is being backed up by something more enterprisey than Time Capsule, hopefully) and you can lay down a ...
