I work at a large international development charity in London, as International Operations Manager. I manage a team of Regional ICT Service Managers, based in developing world countries, who keep our users happy through fixing problems, setting up great connectivity and generally making sure users can do their day jobs.

I previously worked at the same place as International Network Systems Analyst. I looked after a bunch of ICT systems in offices in the developing world, as well as looking after systems in our HQ. I gained a lot of knowledge in that job, and the techy side competes with the people stuff in the new role, hence I still hang out here a lot.

I'm passionate about the use of ICT in developing countries, both in terms of dealing with the inherent problems for ICT in those places, and using ICT as a tool for development.

comment How should I manage a domain that has certain nameservers but MX records pointing elsewhere?
Setting the NS record for the domain defines the server that is authoritative for the domain. Unless you have a good reason to do that, I would leave those settings alone. The Linode DNS management is there since they offer the service. You don't need to use it unless you know why.

comment Ubuntu Server and Hyper-V
Give some more specifics - just because DHCP works for some PCs over there, doesn't mean the settings it assigns will work on a server over here. Use Static addressing until you have figured out how to make it work, then if DHCP assigned address is still broken, you can look at what is assigned and see if there is a problem with it.

In Sharepoint 2007, the help page does indeed say it is 2007!

comment Best Linux for hosting a server
Generally though, CentOS is stable, but if you are interested in upgrading your packages easily, you should note that the official packages for CentOS tend to be rather out of date. Complicating things further, if you want to upgrade say PHP to the latest version on CentOS5, you will either have to upgrade to CentOS6, or use alternative repos, as the official repos for CentOS5 are locked to previous versions. I think we can stand to be a bit faster moving these days. I don't believe Ubuntu has quite the same issues.

Centos has multiple CDs including all the packages you might want to install. You might not use all the CDs in the install process - it all depends which packages you choose and which CDs they are on.

comment Which server solution for an office that doesn't really “need” a server?
I'd recommend having internal DNS if you have 20 PCs accessing the internet. It will speed things up.

You need DNS somewhere, unless no-one ever access the internet, and/or you really really like maintaining host files accross multiple machines. Maybe you just use your ISPs DNS. In terms of running on a different machine - you don't have to, but it is good to keep your core network services separate from other things.

comment Testing whether jumbo frames are actually working
If your path includes a tunnel of some sort (e.g. IPSEC VPN) then it is possible that is clearing the DF bit - which would mean your packet is getting fragmented even though you specified not to. Packet analysis will show if this is the case - your echo-reply packets will be fragmented.

Look up the options and someone might vote you up.

comment Are there any benefits to using a Distributed vSwitch for iSCSI?
This turned out to be a moot question. We had the top of the range Enterprise license for ESX 3.5, but they introduced Enterprise Plus with vSphere, and we found our selves no longer with the full functionality without spending more. Guess which license you need for distributed vSwitches?
