comment Performance Monitor in Linux
I don't think this is a duplicate of the linked question, as he is clearly looking for something simple. I think this is just a case of "I'm not familiar with the basic tools", and not "I need to implement a monitoring infrastructure".

comment ping: unknown host google.com
-1: This question is poorly worded and doesn't explain the actual problem is. I'd edit it myself to correct, but I can't really figure it out enough to even do that. I'll remove the minus one once the question is corrected to be clear enough to determine what it is actually asking.

comment how I can Specifying tcpreplay speed
+1, but wouldn't .086 round to .09 instead of .08? Also keep in mind that depending on the actual packets being replayed, they may not round evenly into the time frame/speed you are attempting to achieve.

comment FreeBSD performance tuning: Sysctl parameter, loader.conf, kernel
This is one of my favorite posts, but I'd really love to see more guidelines about when to adjust some of the various settings posted above. For example, the Shared memory entry towards the top of the sysctl.conf section: how do I know if I want to increase it? How far should I increase it? There are too many different entries here to simply do trial and error with each one. Thanks!

comment Why need to send ARP to ask for MAC address when IP address is already unique?
What happens when station A changes network cards? Or when it adds another?

comment Ping “replies” from same computer with 'Destination host unreachable' (no route to other computer)
+1 I was wondering what the problem was. Wish I could double +1 for the mini wifi sniffing tutorial (I always just bust out kismet in a VM connected to a USB wifi adapter). Too bad srekel never came back to post what the real problem was.

comment XenServer: Editing clone configuration before boot
I'm sure there are good reasons, but I'm curious to hear more about why DHCP isn't an option. Thanks!

comment XenServer: Editing clone configuration before boot
+1 These are the two solutions that I was going to propose, although I'd like to know more about why DHCP isn't an option. I usually just use DHCP and configure my DHCP server with static entries for MACs that I assign to the VMs (ok, not really, I clone the VMs, then run a script that collects their MACs and generates the appropriate dhcpd.conf block, which I then stick into my dhcpd server before booting them; but same difference really).

comment Move VMware ESXi VM to new datastore - preserve thin-provisioning
FWIW, you can also do this from a command line using ovftool.

comment Move VMware ESXi VM to new datastore - preserve thin-provisioning
Assuming version 4.1 or newer, you'll be prompted to use thin or thick when it is imported.

Keep in mind that in the free version of ESXi 5, you are capped to 32GB of RAM.

comment Accessing VMWare Management Network from a different subnet
Perhaps if you articulate exactly what IP addresses and netmasks both the server and the system you are attempting to connect from have, along with their default routes, we might be able to better assist in troubleshooting.

comment Citrix XenServer: how to add RAM to a guest VM without XenCenter?
Sorry Joe, but I do not believe so (although I can not definitively prove it, since I don't have an XS 5.6 up and running). Jesse's answer links to the 5.6 guide that references adjusting memory from the CLI, and portforwardpodcast's answer actually has an example. His example won't actually work in 6.0 though, as the command appears to have changed slightly (I'll post an answer with this info momentarily). Sorry to downvote you.

-1. This is an incorrect answer, at least for the current XenServer.

comment ESXi: Allowing a guest OS to use other disk drives in server
Do you just want the raw space or is are you trying to avoid formatting the RAID10 as VMFS?

comment Can't install python-setuptools with yum on Ubuntu. Missing repolist
Honestly, I have no idea. If I wanted to use yum, I's use a RedHat based system like CentOS instead of a Debian based system like Ubuntu. My understanding is that yum in based on aptitude anyway. If you really want to learn about it, I'm sure man yum will get you started.

Oh yea, and make sure there isn't some new firewalling going on post-upgrade.
