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 Cisco VPN endpoints disconnecting from a VLAN
My config is almost exactly the same. Only missing the management tunnel line. Each VLAN we have gets a subnet, so I expect you are right on that count. So are you saying that each subnet gets its own tunnel, and for some reason that is timing out? Interestingly, we have lost this problem on one of the ASAs by removing a cheap router from the equation. The D-link used to be connected in between the ASA and the ISP equipment. Now the ASA connects directly to the ISP equipment, and the problem has gone. In some cases the cheap routers is the ISP equipment though, so not quite as easy.

That looks like exactly what I am looking for. Thanks!

comment Dealing with moved documents and sites in Sharepoint
Unfortunately, the rewriter at www.iis.net seems to be only for IIS7 - we're still in IIS6 land as far as our Sharepoint infrastructure is concerned.

comment Dealing with moved documents and sites in Sharepoint
When you talk about the long terms scan and update - are you suggesting there is some way of fixing links within Office documents stored in Sharepoint?

comment Configuring subdomain using apache virtualhost problem
That looks ok to me. The config file you are using is definitely the one that Apache is using right? You've cleared the cache in your browser? You haven't set ServerName or ServerAlias anywhere else in the config?

comment website cannot be found unless I put IP address in host file
Remember that in DNS www.domain.com is different from domain.com unless you are using wildcards.

comment ESX(i) Interface Bonding ala Linux?
That sounds super simple indeed. I guess that this only works for redundancy - can you do bonding where each interface is connected to a different switch. vSwitches are only on vSphere (ESX 4.0) right? Gotta upgrade our clusters!

comment sendmail vs smtp server
+1 keep it as simple as possible, unless you know a good reason to make it more complex. If you do have a good reason, get postfix, buy a book on it, and learn all about MTAs.

comment Dealing with moved documents and sites in Sharepoint
Those articles discuss moving sites between content databases, which doesn't necessarily result in changed URLs. We want to change the URLs so they reflect the site and organisational structure, yet make sure as few links as possible break (or handle broken links in a user friendly way).

comment How do I calculate the Number of Web FrontEnd Servers For SharePoint
+1 - this is a good place to start. In case you are thinking of doing this in VMware or HyperV (which would make rolling out additional WFEs even easier) you should check out blogs.msdn.com/uksharepoint/archive/2009/02/26/… which discusses in detail. One bit of advice I wish we'd had originally was to make sure the index server is physical not a VM, due to the IO. With 40k, you might also want to look at something a bit more substantial than windows NLB for load balancing/high availability.

comment Really clear introduction to Sharepoint architecture
Just to clarify - I have been administering Sharepoint for three years. I really need to explain some of this to other people, as we probably need to redo our Sharepoint architecture. I need to be able to discuss this with people who have no idea what a managed path is etc.

comment Trouble with IIS SMTP relaying to Gmail
I agree - if you have the TLS box ticked in the SMTP server config, then for some reason this isn't working right, and something like Wireshark may help you figure out why.

comment Can any of the popular IM networks work like this?
+1 That's a great answer - use one IM product for internal system, and use a client that allows access to multiple IM systems. That gives you your redundancy and doesn't rely on your customers using a particular IM network. Pidgen will hook into XMMP locally, then all the major IM networks apart from Skype.

comment Slow Read/Write Performance over iSCSI SAN
"You probably are also using ethernet instead of fibre which is also not help performance." I'm not sure this is always the case. If you have a dedicated ethernet network for the SAN with decent switches, and bonded links to your SAN array and hosts, you may get performance better than some fibre channel solutions.

Nice discussion on some of this here - grimwell.wikispaces.com/tftpd

comment TFTP uploads failing
Aha - a bit of a breakthrough. I installed auditd, and things started to appear in the audit log relating to tftp. I then used grep tftp /var/log/audit/audit.log | audit2allow -M tftpwrite to generate a SELinux rule to allow tftp to write. I then applied this with semodule -i tftpwrite.pp and restarted xinetd. Now I am able to save over existing files, which gets me some of the way there. I am still unable to create new files, despite the presence of the -c flag in the config for xinetd. Would be nice to be able to create from network devices saving their config via TFTP.

comment TFTP uploads failing
Ok - I've now tested running outside of xinetd using the following command: in.tftpd -l -c -v -u root -s /tftpboot This seems to work ok. However, when running with the following xinetd config, which I believe does the same thing, I get the same error with writing files.

comment TFTP uploads failing
Unfortunately I do have the -s flag set. Reading files works just fine, so connectivity is functioning. There is no /var/log/audit/audit.log. Not familiar with strace - I guess that is the next thing to try.
