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 NPS will not add Radius client
Not only that, it doesn't even evaluate a CIDR IP address to check how many clients are covered - I'm using a /27 which is only 30 addresses. I tested all the way to /32 and the error message is always returned. I'd class this as a bug.

comment Which field to use when authenticating against Active Directory?
Thanks for that - I was looking for the formats they accepted in the paramter list, but they put it in remarks. Great.

comment Which field to use when authenticating against Active Directory?
Does LookupAccountName accept UPN or sAMAccountName or fully qualified DOMAIN\sAMAccountName, or all of the above? It isn't clear from the documentation you link to.

comment Which field to use when authenticating against Active Directory?
I've encountered a few applications (both internally developed and things other people have done) that authenticates through LDAP using the cn field. This field now gets updated automatically in AD Admin Center (it's labelled Full Name) if you change the first or last name fields, meaning you can't assume that the cn field can be considered a username field. Have these developers been using the wrong field, or has Microsoft broken cn?

comment How can I run a scheduled task on a Windows 2008 R2 Domain Controller as a non-admin user?
I checked and the user was already a member of this group - that hasn't enabled them to run this script.

comment Fetching all PHP files and store their size
It's not that people don't like links. Its answers that ONLY have links - so don't do much more than Google, and if the link goes dead all the value of the answer is gone. But you seem wilful in not understanding this, so welcome to your downvotes...

comment How to check who blocks ICMP during MTU path negotiation?
In my experience, many ISP have some network equipment which has enough of ICMP blocked to break Path MTU Discovery. I suspect some vendor is shipping equipment with this blocked by default. This results in some ISPs having some routers/switches where PMTUD breaks - dynamic routing makes the problem intermittent. Traceroute and ping used correctly can help you determine where the problem arises.

I'll give you the benefit of the doubt that your aren't trolling. Link to the site by all means, but why not include some context with your answer, like how to use OSSEC for integrity check. That adds value to the link and makes for a good answer.

There are a whole slew of reasons why link only answers aren't valued here. Respect the feedback that others give you. Read serverfault.com/help/how-to-answer

comment Fetching all PHP files and store their size
While this link may answer the question, it is better to include the essential parts of the answer here and provide the link for reference. Link-only answers can become invalid if the linked page changes.

You might go into detail about how you would use OSSEC to do an integrity check.

comment Is it okay to use a SSH key with an empty passphrase?
Until your client laptop gets stolen and used to breach your perimeter before anyone has a chance to revoke the SSH key. A passphrase on the key would give you more time to revoke the keys.

comment User security settings for scheduled task on Windows Server 2008 R2
There is a hard coded SQL server account in the EXE that has the permission to write to the database. This is separate from the AD user used to run the scheduled task. When the executable is run as an AD Domain Admin, it works, when it is run as a normal user, it doesn't. Are you suggesting that the AD user the task is run as has a bearing on whether the exe can talk to SQL?

comment Windows 2008 R2 AD servers on fanless flash based systems
Update - I've now deployed four of these with another 11 to go. Very happy with this choice. The fanless stuff looked cool, but the cost of the microservers was so low it was hard to argue with.

comment Measuring network latency
Requests for recommendations of products are off topic, but saying what tool to use, particularly generic ones, surely is on topic, else most of the content here will have to go.

comment Multiple-NIC vMotion in vSphere 5 with separate core switches
Oh yes - it is a lesson learnt but not a lesson easy to put into practice. Still stuck with the two cores - next hardware refresh will be the first opportunity to make a change.
