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

brew update reminder

Posted by jpluimers on 2019/01/01

Reminder to self:

==> Caveats
==> nss
nss is keg-only, which means it was not symlinked into /usr/local,
because Firefox can pick this up instead of the built-in library, resulting in
random crashes without meaningful explanation.

Please see https://bugzilla.mozilla.org/show_bug.cgi?id=1142646 for details.

If you need to have nss first in your PATH run:
echo ‘export PATH=”/usr/local/opt/nss/bin:$PATH”‘ >> ~/.bash_profile

For compilers to find nss you may need to set:
export LDFLAGS=”-L/usr/local/opt/nss/lib”
export CPPFLAGS=”-I/usr/local/opt/nss/include”

For pkg-config to find nss you may need to set:
export PKG_CONFIG_PATH=”/usr/local/opt/nss/lib/pkgconfig”

==> sphinx-doc
sphinx-doc is keg-only, which means it was not symlinked into /usr/local,
because this formula is mainly used internally by other formulae.
Users are advised to use `pip` to install sphinx-doc.

If you need to have sphinx-doc first in your PATH run:
echo ‘export PATH=”/usr/local/opt/sphinx-doc/bin:$PATH”‘ >> ~/.bash_profile

==> sqlite
sqlite is keg-only, which means it was not symlinked into /usr/local,
because macOS provides an older sqlite3.

If you need to have sqlite first in your PATH run:
echo ‘export PATH=”/usr/local/opt/sqlite/bin:$PATH”‘ >> ~/.bash_profile

For compilers to find sqlite you may need to set:
export LDFLAGS=”-L/usr/local/opt/sqlite/lib”
export CPPFLAGS=”-I/usr/local/opt/sqlite/include”

For pkg-config to find sqlite you may need to set:
export PKG_CONFIG_PATH=”/usr/local/opt/sqlite/lib/pkgconfig”

==> openssl
A CA file has been bootstrapped using certificates from the SystemRoots
keychain. To add additional certificates (e.g. the certificates added in
the System keychain), place .pem files in
/usr/local/etc/openssl/certs

and run
/usr/local/opt/openssl/bin/c_rehash

openssl is keg-only, which means it was not symlinked into /usr/local,
because Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries.

If you need to have openssl first in your PATH run:
echo ‘export PATH=”/usr/local/opt/openssl/bin:$PATH”‘ >> ~/.bash_profile

For compilers to find openssl you may need to set:
export LDFLAGS=”-L/usr/local/opt/openssl/lib”
export CPPFLAGS=”-I/usr/local/opt/openssl/include”

For pkg-config to find openssl you may need to set:
export PKG_CONFIG_PATH=”/usr/local/opt/openssl/lib/pkgconfig”

==> openssl@1.1
A CA file has been bootstrapped using certificates from the system
keychain. To add additional certificates, place .pem files in
/usr/local/etc/openssl@1.1/certs

and run
/usr/local/opt/openssl@1.1/bin/c_rehash

openssl@1.1 is keg-only, which means it was not symlinked into /usr/local,
because openssl/libressl is provided by macOS so don’t link an incompatible version.

If you need to have openssl@1.1 first in your PATH run:
echo ‘export PATH=”/usr/local/opt/openssl@1.1/bin:$PATH”‘ >> ~/.bash_profile

For compilers to find openssl@1.1 you may need to set:
export LDFLAGS=”-L/usr/local/opt/openssl@1.1/lib”
export CPPFLAGS=”-I/usr/local/opt/openssl@1.1/include”

For pkg-config to find openssl@1.1 you may need to set:
export PKG_CONFIG_PATH=”/usr/local/opt/openssl@1.1/lib/pkgconfig”

==> icu4c
icu4c is keg-only, which means it was not symlinked into /usr/local,
because macOS provides libicucore.dylib (but nothing else).

If you need to have icu4c first in your PATH run:
echo ‘export PATH=”/usr/local/opt/icu4c/bin:$PATH”‘ >> ~/.bash_profile
echo ‘export PATH=”/usr/local/opt/icu4c/sbin:$PATH”‘ >> ~/.bash_profile

For compilers to find icu4c you may need to set:
export LDFLAGS=”-L/usr/local/opt/icu4c/lib”
export CPPFLAGS=”-I/usr/local/opt/icu4c/include”

For pkg-config to find icu4c you may need to set:
export PKG_CONFIG_PATH=”/usr/local/opt/icu4c/lib/pkgconfig”

==> ruby
By default, binaries installed by gem will be placed into:
/usr/local/lib/ruby/gems/2.6.0/bin

You may want to add this to your PATH.

ruby is keg-only, which means it was not symlinked into /usr/local,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.

If you need to have ruby first in your PATH run:
echo ‘export PATH=”/usr/local/opt/ruby/bin:$PATH”‘ >> ~/.bash_profile

For compilers to find ruby you may need to set:
export LDFLAGS=”-L/usr/local/opt/ruby/lib”
export CPPFLAGS=”-I/usr/local/opt/ruby/include”

For pkg-config to find ruby you may need to set:
export PKG_CONFIG_PATH=”/usr/local/opt/ruby/lib/pkgconfig”

==> qt
We agreed to the Qt open source license for you.
If this is unacceptable you should uninstall.

qt is keg-only, which means it was not symlinked into /usr/local,
because Qt 5 has CMake issues when linked.

If you need to have qt first in your PATH run:
echo ‘export PATH=”/usr/local/opt/qt/bin:$PATH”‘ >> ~/.bash_profile

For compilers to find qt you may need to set:
export LDFLAGS=”-L/usr/local/opt/qt/lib”
export CPPFLAGS=”-I/usr/local/opt/qt/include”

For pkg-config to find qt you may need to set:
export PKG_CONFIG_PATH=”/usr/local/opt/qt/lib/pkgconfig”

==> python
Python has been installed as
/usr/local/bin/python3

Unversioned symlinks `python`, `python-config`, `pip` etc. pointing to
`python3`, `python3-config`, `pip3` etc., respectively, have been installed into
/usr/local/opt/python/libexec/bin

If you need Homebrew’s Python 2.7 run
brew install python@2

You can install Python packages with
pip3 install <package>
They will install into the site-package directory
/usr/local/lib/python3.7/site-packages

See: https://docs.brew.sh/Homebrew-and-Python
==> youtube-dl
Bash completion has been installed to:
/usr/local/etc/bash_completion.d

zsh completions have been installed to:
/usr/local/share/zsh/site-functions
==> cabal-install
Bash completion has been installed to:
/usr/local/etc/bash_completion.d
==> node
Bash completion has been installed to:
/usr/local/etc/bash_completion.d
==> hub
Bash completion has been installed to:
/usr/local/etc/bash_completion.d

zsh completions have been installed to:
/usr/local/share/zsh/site-functions
==> gnupg
Once you run this version of gpg you may find it difficult to return to using
a prior 1.4.x or 2.0.x. Most notably the prior versions will not automatically
know about new secret keys created or imported by this version. We recommend
creating a backup of your `~/.gnupg` prior to first use.

For full details on each change and how it could impact you please see
https://www.gnupg.org/faq/whats-new-in-2.1.html
==> mas
Bash completion has been installed to:
/usr/local/etc/bash_completion.d
==> pandoc
Bash completion has been installed to:
/usr/local/etc/bash_completion.d
==> go
A valid GOPATH is required to use the `go get` command.
If $GOPATH is not specified, $HOME/go will be used by default:
https://golang.org/doc/code.html#GOPATH

You may wish to add the GOROOT-based install location to your PATH:
export PATH=$PATH:/usr/local/opt/go/libexec/bin

macOS Sierra: Change the order of the network ports your computer uses to connect

Posted by jpluimers on 2018/10/15

Very useful when you want to give your WiFi less priority than an USB or Thunderbolt network adapter: [WayBack] macOS Sierra: Change the order of the network ports your computer uses to connect.

It is not just that the topmost adapter gets more priority: it also determines the DNS search!

Anyway: after choosing “Set Service Order” on the right, choose the order as seen below.

PS: Since Apple is cleaning up their site, only the above WayBack works, but luckily the below link explains it in a very similar way when using Locations:
