Testing SMTP from the console on Linux, BSD and Mac OS: swaks and smtp-cli Perl script clients

Posted by jpluimers on 2019/01/03

Testing SMTP using telnet is tedious as you have to remember the commands and responses in the SMTP protocol. It gets even harder when doing SMTP AUTH, as then you have to base encode a bunch of strings [WayBack] How to Test SMTP AUTH using Telnet [Wiki] | NDCHost

Luckily there is a Perl script swaks: [WayBack] Swaks – Swiss Army Knife for SMTP which does ESMTP and LMTP as well as TLS.

The funny thing is that the repository at jetmore/swaks: Swaks – Swiss Army Knife for SMTP only has the readme, but the not the script which you can get from [WayBack] swaks.pl.

Despite that, most Linux distributions have an installation package.

[WayBack] swaks for OpenSuse is in the [WayBack] network repository, so for Tumbleweed (actually: Factory) on Raspberry Pi you need to perform this:

zypper addrepo http://download.opensuse.org/repositories/network/openSUSE_Factory_ARM/network.repo
zypper refresh
zypper install swaks

On Mac OS X it is even easier: if you have the homebrew package manager installed, you just install the [WayBack] swaks formula using the [WayBack] swaks.rb script:

brew install swaks

Note there is also the smtp-cli Perl script which I mentioned before at Fake/Mock SMTP servers and services for use during development, which also does TLS, but few environments have ready built packages for them. If you still want to try it out:

For SMTP AUTH:

swaks -tls --to jeroen.wiert.me@pluimers.com --from jeroen.wiert.me@pluimers.com --server smtp.xs4all.nl --auth-user username

Which prompts for the password, then outputs like this:

=== Trying smtp.xs4all.nl:25...
=== Connected to smtp.xs4all.nl.

The biggest lie I tell myself is not about new years resolutions.

Posted by jpluimers on 2019/01/01

The biggest lie I tell myself is “I don’t need to write that down, I’ll remember it”

It’s likely older, but the oldest reference I could find was 2012 [WayBack].

So before I forget:

Happy New Year everyone!

With the above quote, it is no coincidence I started my blog even earlier (in 2009): it’s my off-line memory, way better readable than my hand-writing and indexed by various search engines.

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

Monitoring: you can ignore ShellHWDetection service warnings on when it’s not started

Posted by jpluimers on 2018/12/31

I’m monitoring quite a bunch of Windows machines with Zabbix.

One of the services I turn off for monitoring is ShellHWDetection as otherwise you get this notification often:

Service "ShellHWDetection" (Shell Hardware Detection) is not running (startup type automatic)

When it happens, it’s always when there is nobody logged on to the machine. But sometimes you do not get this message. I’ve not fully figured out the pattern well, but since the service is associated with auto-play of inserted CD/DVD/USB and other media, I don’t bother too much.
