ssh from Mac OS X to ESXi: “WARNING: terminal is not fully functional”

Posted by jpluimers on 2019/03/29

When connecting from my Mac to my ESXi rig, some commands (especially less) show this output:

WARNING: terminal is not fully functional

So I created this alias to connect from my Mac to the internal address of my ESXi rig:

alias ssh-esxi-X10SRH-CF-internal='TERM=xterm ssh -p 22 root@192.168.71.91'

The trick is the bold part: TERM=xterm (which you can also replace by export TERM=xterm; if you want future ssh sessions to use the same [wayback] TERM setting).

The reason is that the Mac defines the TERM variable as containing xterm-256 which is defined on the Mac itself, but ESXi has a hard time coping with it.

Some Mac OS and Xcode combinations had a problem with xterm-256 not being present ([WayBackmacos – Terminal strangeness after installing Xcode on Lion – Super User), but this isn’t the case on my system:

$ ls -alh `find /usr/share/terminfo | grep 'xterm-256color'`
-rw-r--r-- 1 root wheel 3.2K Jul 30 2016 /usr/share/terminfo/78/xterm-256color

On the Mac you really want to use xterm-256color as it looks way better than xterm-color or xterm: [WayBacklinux – What is the difference between xterm-color & xterm-256color? – Stack Overflow (thanks [WayBack] Chris Page!)

It seems I already did something similar on ESXi itself to get esxtop working: ESXi: when esxtop shows garbage. That was on the ESXi side and works as well for this problem too.

However, it is a bit harder to have a script run during ESXi boot time that sets this, so it is easier to fix this on the Mac side.

It works for all OS X and ESXi versions I’ve tested so far.

Many Mac OS X / MacOX / whatever versions: Unable to modify the volume with the keyboard – Ask Different

Posted by jpluimers on 2019/02/22

This has happened to me on most Macs with most Apple Mac OS X / MacOS / whatever versions: the built in sound controls for internal speakers and head phones fail to work (keyboard shortcuts and UI both fail).

The solution at [WayBackmavericks – Unable to modify the volume with the keyboard – Ask Different works, but be sure to require the kernel module steps:

open up a Terminal window and run:

sudo killall coreaudiod
sudo kextunload /System/Library/Extensions/AppleHDA.kext 
sudo kextload /System/Library/Extensions/AppleHDA.kext

For my memory:

What’s new in this update:

It’s time for the first update of the year! We appreciate all your comments sent to us through the App Store, in-app feedback and email; and continue focusing on making this app better with each release.

In this version we addressed the following issues:

  • Added support for the AVC (420 and 444) codec, available when connecting to current versions of Windows 10.
  • In “fit to window mode”, a window refresh now occurs immediately after a resize to ensure that content is rendered at the correct interpolation level.
  • Fixed a layout bug that caused feed headers to overlap for some users.
  • Cleaned up the Application Preferences UI.
  • Polished the Add/Edit Desktop UI.
  • Made lots of fit and finish adjustments to the Connection Center tile and list views for desktops and feeds.

Please continue to send us feedback. We read it all and factor it into our planning. If you encounter any errors, you can always contact us via Help > Report an Issue.

NOTE: There is a bug in macOS 10.14.0 and 10.14.1 that can cause the “.com.microsoft.rdc.application-data_SUPPORT/_EXTERNAL_DATA” folder (nested deep inside the ~/Library folder) to consume a large amount of disk space. To resolve this issue, delete the folder contents and upgrade to macOS 10.14.2. Note that a side-effect of deleting the folder contents is that snapshot images assigned to bookmarks will be deleted. These images will be regenerated when reconnecting to the remote PC.

TigerVNC on Mac OS X with homebrew to check why a Screen Sharing.app connection fails.

Posted by jpluimers on 2019/01/18

Two installation options for TigerVNC:

The [WayBackTigerVNC  viewer gives a bit more details on failing VNC connections than the stock OSX Screen Sharing.app does: after performing the logon, the connection would just stall, but TigerVNC would should  “write broken pipe (32)” after the logon. Most of the linked search results indicated the VNC server was having a state problem.

So I restarted the VNC server, after which connections could be made again in both tools.

I actually prefer the stock Screen Sharing.app as:
