Hello, Which software are you using/recommending as a softphone client on Windows? I will use it for connecting my SIP account. I installed X-Lite, but it is not accessible at all. Thanks.

Re: [Blind-sysadmins] Access to VMware ESX 5.5 (both gui and VM guest console)

Hi, When I am talking about Packer, I am talking about Hashicorp's Packer that builds the image. When working with VMWare, it has two options, either to start from an ISO image or a VMX file. The thing I like about Packer on ESX is it gets you past the boring part of logging onto the console, pressing escape at the right time etc. You then get a predictable image every time that can be used in other places later on. This saves you time as it means that you don't need to provision a new machine and wait for that to complete etc. How many times have you tried to provision a new machine and have some part of it fail as it couldn't access a network file, or something went wrong with deployment etc.? I realise that in most enterprises this type of technology is seen as very new and certainly in the place where I work the team I am in are the only ones using this type of workflow, the rest of the teams are still using older ways to get machines up which are not as usable. I think that in time we will see a lot more of this automation which is good news for us. >From an AWS point of view you need to think about servers very differently, the servers I spin up in AWS last only for a few weeks, and in AWS terminology for a lot of places that is a long time. I am different in that I am working with a Windows stack, although I do use some Redhat in some places. The AWS console is not too bad, but the real power comes from automating the provisioning of the network and the systems. I typically make heavy use of the AWS PowerShell, and Hashicorp Terraform to build the infrastructure. I am building the infrastructure from the networks, each subnet, connectivity between the subnets, firewalls, network appliances etc., all controlled via Terraform. In terms of the machines itself I have set things up so I never really need to log into a machine, the machines have health checks to identify whether specific services and files are in place, and if these fail the machines are killed. I know a machine is up properly because at the end of the Chef run the system calls out to a deployment server and so I can see the machine requesting application code and the code going on the server. All very accessible and no interacting with a server rack or network cable! I realise a lot of enterprises are a long way from this, where I work we have an enormous amount of ground to make up in getting other parts of the business on-board with the new technology, and it changes fundamentally the way in which a team works. For example I am having to do a lot of architecture work, as well as work on lower levels of the network stack, for example creating and testing the firewall rules, whereas before I was only working on the server side. I don't know how long I will be able to continue this, as there are lots of changes being proposed, so for now I am trying to learn as much as I can until I have to move. Hope this helps, Andrew. -----Original Message----- From: Blind-sysadmins [mailto:blind-sysadmins-bounces@lists.hodgsonfamily.org] On Behalf Of Ryan Hutchings Sent: 01 April 2017 22:56 To: 'Blind sysadmins list' <blind-sysadmins(a)lists.hodgsonfamily.org> Subject: Re: [Blind-sysadmins] Access to vmware ESX 5.5 (both gui and VM guest console) Hi Andrew, We do use packer along with kickstart files that are stored on a network server; virtual machines are then instructed to boot from PXE to kick (install os), and then we have a postinstall script executed after the os is installed, which installs puppet and configures iptables, ssh etc after which point I have ssh access and can connect to the machines.

Need recommendation for voice recording?
by Can Kırca 02 Apr '17

02 Apr '17

Hello, I know that there are system admins in this list. Maybe this is an off-topic, but decide to ask. We are using cloud based telephone system with Red5 to receive calls, dial numbers and talking between locations. I have to record welcome and some IVR messages at 8KHZ-16bit. Do you have any accessible voice recorder software recommendation? I know that audacity is working, but looking for an other solution for that. I have Sonar and Samplitude as well, but not sure how to set above settings with them . Thanks in advance.

Hello, Which software are you using/recommending as a softphone client on Windows? I will use it for connecting my SIP account. I installed X-Lite, but it is not accessible at all. Thanks.

Windows Server 2016
by George Bell 01 Apr '17

01 Apr '17

I've a feeling it won't be too long before some of you may be faced with installing Windows 2016 Server. You may want to bear the following in mind as it cost us a week and much frustration before stumbling on the solution. The initial setup of a Dell PowerEdge R330 server took some time itself to get set up since its BIOS and associated iDrac needed to be set up to boot from either CD or USB drive before the hard drive. Once we found a good technical support person at Dell, that issue was soon resolved. Installing Server 2016 from the USB drive was a surprisingly easy and intuitive operation. I cannot speak for accessibility, but I was assisted by telephone a totally blind friend with much server experience. His comment was along the lines that Microsoft had finally managed to tidy the whole process up leading to Server Manager. Within a very short time - less than an hour in fact - we had one Windows 10 and 3 Windows 7 workstations all subscribed to the new domain. However, we soon found issues in accessing (or rather NOT accessing) the Internet. We checked all manner of things in Server Manager to ensure the Gateway was correct, etc., etc., etc.. We contacted our ISP, who advised us that all was well at the Router, which we could both ping and access. Finally we rang Dell, who spent over an hour going through all the same settings yet again. Eventually we found we did a Windows + R on workstations, enter \\[Domain name] see the shares there we would be able to run IE. Now bear in mind that during the 2016 server install, we had elected to use only one of the two Ethernet ports, and disable the second, and all indications in Server Manager confirmed this. It was pure chance that I had reason to look at Device Manager, and spotted that the second Ethernet port was operational and moreover had an IPv4 IP address way outside our Domain. Back to Server Manager and it said it was disabled. So back to Device Manager and disabled it there. Suddenly after a reboot, all began to work as it should. Have since reported this to our ISP and our Dell guy, and it appears they had begun to get others with the same problem - which of course they could now resolve. I hope this helps at least one of you. George.
