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 Running two subnets over the same physical LAN
Ok - I'll admit this is pretty similar to serverfault.com/questions/25907/… but I am not interested in using VLANs - just whether or not there are strong reasons for putting resources into fixing this, or I can stop worrying about it.

comment Is this a 'port scan'?
I would consider the first 2 steps not to be "beefing up" the security of ssh. They are minimum requirements as far as I am concerned.

comment Want to start using thin clients
If you are only looking at fixed workstations (no laptops) then you could go this way, but you need a minimum of two servers to have any redundancy. If you only have one server and it fails for any reason, there will be 25 angry users bothering you while you are trying to fix it.

comment Is it best practices to have a network card for each virtual machine on a server?
I'd go so far as saying that if you need the full I/O for networking, then you probably also need dedicated resources in other areas, so why use a VM for this? Virtualisation isn't going to be the best option for everything.

It's a community wiki so feel free to add things, or of course provide your own answer :-)

comment Can you help me with my software dependency issue?
I think it would be useful to provide a section that discusses the issue of library dependencies which can be a bit trickier to solve - but I am less experienced in this - anyone care to contribute?

comment Small remote network fileserver access
The subnet only allows for one host on the network, so how are you going to have any clients which are using this router? I think you need to brush up on your networking or get paid for help with this task.

comment DELL switch 6248 port and mac mapping using SNMP
This is making a bunch of assumptions about whether the OP has the infrastructure or knowledge to make use of this. Your answer would be more useful if it included information about what the OP will need to set up in order to use the code you give.

comment Small remote network fileserver access
You'll need to provide details of your VPN routers - what brand and model are they - before you can get any kind of answer. I can tell you right now that Location 2 won't work unless you are doing a bunch of other things - that subnet mask doesn't allow any other hosts in the same subnet. And Location 4 doesn't look like a valid private address.

comment Can't compile CentOS 5, Ruby 1.9.2 and OpenSSL 1.0.0c
@pstinnett You could investigate using different yum repos - there may be one out there that uses the version of OpenSSL that you need. Otherwise you are going to have to figure out how to handle dependencies when building from source - a basic skill for any sysadmin.

comment ESXI 4.1 -5.1 upgrade
I feel your pain on the distance issue - I look after hosts that are even more remote. But if you really need to do some maintenance of that host then it probably justifies either going there in person, or shipping a slot in replacement.

comment ESXI 4.1 -5.1 upgrade
If the CPU usage is worryingly high when running VMs on the server, then an upgrade probably won't help - you are simply pushing the host too far. If it is running high with no VMs running on it, then you have serious problems!

comment Why can't I RDP to a new Domain Controller with an account in Domain Admins group?
I removed the Active Directory Domain Services from the server. Then I disabled our anti-virus on-access scanning and ran dcpromo again. This time it seems to have worked. I guess that may have blocked some installation. Reenabling on-access afterwards configured to exclude for Domain Controller as directed by Microsoft .

comment Why can't I RDP to a new Domain Controller with an account in Domain Admins group?
No - fresh install of Windows Server 2008 R2 from boot media on a brand new VM, then added the Active Directory Domain Services role.

comment Why can't I RDP to a new Domain Controller with an account in Domain Admins group?
Thanks - if I am wiping this VM, do I need to follow any steps to undo the dcpromo that I already ran? I am assuming that if I just wipe it I will hit problems with my other domain controllers still trying to replicate with it - the setup does seem to have worked partially.

comment Why can't I RDP to a new Domain Controller with an account in Domain Admins group?
It's a VM so I can login locally through vSphere client console. But that isn't normally how we do things, and if RDP isn't working as expected then what else is wrong? There is a group called Remote Destkop Users on our domain - Domain Admins is a member of this amongst others.

Why not put your config right here in the question? You do want an answer don't you?

comment How to automatically get abuse email address based on IP address
Just because a tool is old doesn't mean it doesn't do the job well. The wheel was invented a long time ago - we don't need to reinvent it just because it is old.

comment Difference between GBIC and SFP
I think all the close votes and down votes are there because you used a bunch of abbreiviations in your question, and gave no background. This makes your question less likely to show up in searches making it less likely that the answer you got is findable and useful for someone else. Please write your questions a bit more fully in future, for the greater good.

comment Difference between GBIC and SFP
Both of them are all the same :-) This is the start of a joke right?
