I have been using rsync for years now to sync directories around on VMware ESXi systems with great success.
Usually when upgrading to new physical machines, I synced the things to migrate to a big disk, then physically mounted that disk in a new machine.
Not this time: because of an unscheduled event I had to bring up the target machine in a different place before I could assemble the data on the big disk.
But since there was a network tunnel between the networks of both ESXi machines, I wanted to transfer over ssh: a thing I had done numerous times between various Linux and unix machines.
The cool thing is that rsync supports remote connections over ssh out of the box. Between ESXi machines, I bumped into this error though:
sh: rsync: not found
rsync: connection unexpectedly closed (0 bytes received so far) [Receiver]
rsync error: error in rsync protocol data stream (code 12) at io.c(226) [Receiver=3.1.2]
Command exited with non-zero status 12
The last three lines are collateral of the first line, which I queried [Wayback/Archive] “sh: rsync: not found” – Google Search. Further below I will go deeper into the rabbit-hole I took, but the actual solution was to Read the rest of this entry »

This archive seems to have very recent HTML5 renderings of many man pages from their troff or mdoc sources: [Wayback/Archive] Man Pages | ManKier.
I bumped into it via [Archive/Archive] ipmitool: utility for controlling IPMI-enabled devices | ipmitool Commands | Man Pages | ManKier when writing Some links on Dell R730xd fan noise.
The site is not only very up-to-date on rendered man pages, but the rendering has great features too. Read more on those at [Wayback/Archive] About | ManKier.
A nice history on how ManKier came to be is at [Wayback/Archive] Blog – ManKier. It’s less than a dozen posts, and recommended reading.
Oh, I almost forget: I have added the man search shortcut to my browsers; these two examples should get you going by adding www.mankier.com/?q=%s as a search template:

Some combinations of hardware/OS will result in high FAN speed despite low power usage on Dell R730/R730xd systems.
For me, altering the BIOS or iDRAC thermal settings did not solve it, nor did updating all firmwares to the most recent versions, so I went digging further.
Below are some links in case I want to resolve that (after figuring out that Dell R730 and R730xd are 13G systems).
There are lots of quotes in them as it will help me find back the information later on.
Note to self: I really wonder what the difference between raw 0x30 0xce and raw 0x30 0x30 is (I think 3rd party PCIe support and forced fan speed level) and how they differ from the system.thermalsettings.ThirdPartyPCIFanResponse setting.
