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.

10 kids, 1 computer. You could teach them Extreme Programming in five groups of two :-)

Are those voting to close suggesting this is better on IT Security (security.stackexchange.com)?

comment Spanning Tree required/desired for Port-Channel?
Ended up doing this. We had all kinds of problems because we had MSTP set up on our Cisco switches, and this was not noticed by the consultants who installed the Dell switches, which didn't have MSTP set up. Dell switches at core, so unless everything stopped working we weren't in a position to experiment. I got promoted and it is no longer in my sphere of interest...

comment Should email system be virtualized?
Virtualisation may be quickest way to balance your risk (although not your load). Strongly recommend that you don't consider Physical to Virtual (p2v) conversion if you do virtualise.

comment sshd running but no PID file
@ChrisS - yes. As stated above, the PID file exists after a reboot. After killing the sshd process that was running, and then starting it with service sshd start the PID file exists again. Haven't seen it disappear again yet.

comment sshd running but no PID file
Ok - with sshd_config using default AddressFamily (any) I only get the output showing bind to IPv6 addresses. With AddressFamily set to inet I see 0.0.0.0:22 in the netstat output. Anyway, that isn't really the problem I'm trying to resolve. I've edited your script so it captures the info you want, but I don't think it indicates any compromise of sshd.

Your grep expression is not returning any results. netstat -lptun | grep ":22" outputs the lines relating to port 22. It's not listening on any other ports that begin with 22.
