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 What are the basics of taking care for a common server?
It is a generic question, but I think it is legitimate as this may well be a customer's only specification initially - the OP is asking for a general list of things that they should consider when asked by a customer to do something unspecific.

comment Multiple Ports Forwards, Most Working, but Not All?
Could you maybe post the relevant parts of your config rather than pasting the whole thing? No-one here is interested in reading your banner!

comment Running Thin behind Apache2
Sounds neither short nor clear then. To be considered a good answer here it should, in the vast majority of cases, stand alone. Links are great, but can be broken all the time so in two days/weeks/years your answer may not be of any use if it just contains links.

comment Tool to monitor for success or failure within a given amount of time
It seems that you already have an alert system in that emails are sent out by your backup system reporting what happened - why go further? Otherwise, can you specify what does your backups? If you want to monitor it by nagios, most likely forget the built in email, and see if it talks SNMP etc. You tagged this with a bunch of monitoring systems - if you are trying to ask which is best, this question will get closed here.

Welcome to Server Fault. Please add some details of what is particularly helpful in the linked to article, in case the link breaks in future.

comment ESXi 4.0.0 with ASUS M5A78L-M LX Motherboard isn't seeing the onboard NIC
It clearly isn't working well if ESXi doesn't see the NIC. Is your motherboard on the compatibility guide? vmware.com/resources/compatibility/search.php

comment ASA 5505 base license and Voice vlan
I don't think this is really a licensing question - basically your limitation around the number of VLANs is due to licensing, but you are asking whether you can do this with the VLANs you have already. Is that correct?

comment Running two subnets over the same physical LAN
The first two are reasons to have a separate broadcast domain for IP camera's but not necessarily reasons not to have two subnets on the same broadcast domain. The third is a good reason, but to be honest, we wouldn't be in the situation we are now if we were working with people who weren't confused by networking anyway... I don't agree with the suggestion that unmanaged switches aren't proper switches - they do the job in a vast range of use cases.

comment ASA 5510 - Routing between Interface
I'd advise downloading the Configuration, CLI and ASDM manuals for 7.0 from the Cisco website, and reading them rather than grabbing configs from some forum - you need to learn how to use your equipment. If you are just starting out, or don't expect to deal with your firewall often, ASDM may be a shallower learning curve for configuring the ASA. Finally, if this is ASA isn't being used in production yet, I would suggest upgrading it to the most recent version it will support (depending on how much memory is installed in the ASA).

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.
