I am the typical "computer nerd", with skills in a number of programming languages and a wide range of computer hardware and software.

comment How should I package a VM template to be cloned repeatedly, along with a single large storage volume for all instances to share?
I've seen OVFs before configured such that the first time you boot them you are prompted for hostname, network config, etc. And you can clone that OVF repeatedly and configure each instance differently. I just don't know what that software/technology is called, to find it and include it in my solution to this problem.

I won't have control over the VM deployment system that the recipient of the template uses.

I feel like this answer falls short in two ways. First, exporting an existing VM as an OVF doesn't give me the configuration options of an exported template. How do I make sure that VMs copied from that OVF get unique hostnames, empty-to-start log files, etc? Second, an OVF export of one of the VMs is not going to contain that 50GB shared volume, is it?

comment What sorts of hardware exists for doing enterprise level web serving in small packages?
@sciurus neat concept, but VGA (or, at the very newest, DVI) is still somewhat of a standard in all of the environments I deal with servers in. I don't think the server market is ready to move to HDMI.

I'll update the question with answers to some of those

comment Can multiple self-registered chef Nodes use the same Client identification?
@jgoldschrafe I do want to create node entries for each of my systems. I don't want to create client entries. The two are distinct on the server, they just seem to be linked in the validation/registration process by default. I want to unlink them.

@ACKumen you should edit the question to omit mention of the error

and by "sudo su" you mean "sudo -i" or at the very least "sudo su -", right?

comment Why did my CentOS 5 production server reboot?
sadly I've got this same problem and /var/log/messages contains no useful information. Nothing is logged for 5-30 minutes prior to syslog registering a restart

@alexus many modern clients show the received date, not the sent date, to protect against malicious or malformed date headers

comment Understand IP addresses and location
@Chris S do you disagree with my 99%? To clarify, I am saying that out of every /24 in the world, the average number of geographic area splits in a single /24 is 2-3. Does it sound more believable that way?

comment Understand IP addresses and location
@ErikA as you realized, "many" from among billions can be "doesn't happen very often", which means that the opposite case is "generally" true. There could be a BILLION pairs of numerically adjacent but physically distant IPs... and the other three billion would still be close to their neighbors.

comment Understand IP addresses and location
@John I am not aware of any single piece of material that would cover this. Assignment of /8 blocks follows some rules, and those rules are published somewhere. One of the emergent results of those rules is that blocks allocated to an entity (most of whom are countries or geographic regions) tend to be sequential, even when they assignments are made years apart. Once a local authority (like ARIN) has a /8, how they distribute it is again governed by rules, and THOSE rules have emergent properties. This continues right down to ISP nodes, which have rules for which house gets which IP(s).

I think you missed the "generally" in the question.

I know it's not fair, but once he edited his question then your answer because [more obviously] wrong. The only way to fix that is to -1 your answer out of the top spot, or for you to edit your answer. There are some discussions on the various meta sites about fixing this phenomenon.

comment Reliable email service for personal use using own domain name
How could an HTTP 500 or 502 possibly be the user's fault? Some users see more downtime with google apps than others. Some accounts have far more downtime. I think it's most likely that Google has one bad machine in a 100-machine cluster, or something similar, so a specific one percent of their users see crappy service while everyone else has no problem.

comment What is the best way to address users storing and streaming music within your company?
@GWLlosa When I purchase a CD, I also have the Fair Use right to format and time shift the contents of that CD for personal use [margin too small for citation]. WHERE I format-shift it to has never been an issue tested in court, but I can't imagine it mattering. I concede the backups point. Easy solution, don't backup mp3 files.

comment How can I prevent someone else's name server registration from pointing to my IP addresses? (i.e. change com zone file)
No. tp.com's registrar (who is a second level registrar, not the .com root authority) is the one who says that ns1.tp.com is a nameserver.

So then that's even worse... If someone is still coming to you as ns1.tp.com then they have cached an old response from ns1.tp.com for ns1.tp.com, and you'd be stuck trying to convince a single internet user (or ISP, or whoever) to clear their DNS cache manually.
