Problem: MacWise cannot connect to local host server (MacOS Sequoia or later )

Message says "No path to host" when you try to open a telnet connection.

In System Settings...

Privacy & Security > Local Network, flip the switch to allow MacWise to find and communicate with devices on your local network.

Cannot type a space when Full Keyboard Access is enabled

MacOS Ventura has a System Setting for Full Keyboard Access in Accessibility settings.

If that is enabled, you cannot type a space in MacWise.

The other problem it causes when enabled is that hitting tab causes each function key to be highlighted each time you hit tab.

Full Keyboard Access is not enabled by default.

But if you have it enabled, you need to turn it off.

In Ventura, select System Settings from the Apple Menu.

In the search field, enter Full Keyboard Access

Then click on Full Keyboard Access under Accessibility.

Turn Full Keyboard Access off.

NOTE: In earlier versions of the MacOS the Full Keyboard Access setting is in Keyboard Shortcuts and you only have a choice for All Controls or Text boxes and lists only. (and you choose the latter for MacWise to work correctly)

MacOS Ventura Compatibility with MacWise

 Macs running MacOS Ventura ( 13.0 ) or later require MacWise version 23 or later.

All previous versions of MacWise will not work with Ventura.

(Those older versions will not display a flashing cursor).

The latest version of MacWise is always here...

SSH Secure Shell Login Falure with Diffie-Hellman - Fix

If you get the following error while trying to connect with SSH...

"Unable to negotiate with xx.xxx.xx.xx port 22: no matching key exchange method

found. Their offer: diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha"

That error is due to the fact that diffie-helllman is an older less secure connection method.

Apple has removed it from the MacOS starting with MacOS Mojave.

If the server you are trying to connect to cannot upgrade their key exchange method for some reason, You can add diffie-hellman to the MacOS.

Here's how to do that:

Launch the terminal app and enter the following command.

sudo nano /etc/ssh/ssh_config

Locate the line ‘ #   MACs hmac-md5,hmac-sha1,hmac-sha2-256,umac-64@openssh.com,hmac-ripemd160′ and remove the Hash/Pound sign from the beginning, and add the extra hashing algorithm that I’ve shown above in red. 

Locate the line ‘ #   Ciphers aes128-ctr,aes192-ctr,aes256-ctr,aes128-cbc,3des-cbc’ and remove the Hash/Pound sign from the beginning.

Then paste the following on the end;

HostkeyAlgorithms ssh-dss,ssh-rsa

KexAlgorithms +diffie-hellman-group1-sha1

The Modified text should look like this:

Ciphers aes128-ctr,aes192-ctr,aes256-ctr,aes128-cbc,3des-cbc                                                                            

HostkeyAlgorithms ssh-dss,ssh-rsa

KexAlgorithms +diffie-hellman-group1-sha1

MACs hmac-md5,hmac-sha1,hmac-sha2-256,umac-64@openssh.com

Now you should be able to connect with SSH

Telnet connection with Apple Silicon Macs

Telnet connection with Apple Silicon Macs sometimes would not connect to the server.

Symptom was just a blank screen as if it were not trying to connect.
When verbose login was selected, you could see an error message that said, "Bad CPU Type".

Solution:  Upgrade to MacWise 21.6  or later.

Telnet connection using VPN

Problem:  Cannot get a login using MacWise with Telnet and a VPN connection.

Error might be, "Failed: Operation timed out"

or it might be "Sorry, you must SET LINE or SET HOST first"

The simple fix can be to set the VPN service order to the top of the list in Network Preferences.

Select System Preferences... from the Apple Menu

Then select Network

Find your VPN in the list of networks in the left column and drag it to the top of the list.

That's it.

Now your VPN has first priority when making a connection to the internet and your telnet connection should work with MacWise.

Note that lots of things can cause a telnet connection to fail but this is one you might never think of.

MacWise and Big Sur (Info about USB to Serial adaptors and MacWise versions)

MacWise version 21 or later is compatible with Big Sur.

www.macwise.com

Version 21.5 is the first version that is a universal app for Apple Silicon and Intel Macs.

It is a 64-bit app.

If you are connecting to your host with a Keyspan USB Serial Adaptor, it will not work with Big Sur.

Keyspan is owned by Tripplite and has not updated their driver to work with Big Sur yet (as of this date, 11/15/20)

However, the Prolific drivers work for other third party USB to Serial adaptors including the Plugable brand here... Plugable PL2303-DB9 USB to RS-232 DB9 Serial Adapter (Prolific PL2303HX Chipset)

Code Sign Error

MacWise versions 20.0.1 through 20.1.4 would quit immediately when you tried to run.
This was an incompatibility with code signing after upgrading to MacOS Catalina 10.15.4

Apple requires all applications to be code signed and notarized with Apple.
Apps will no longer run unless they are authorized by Apple.

This problem was fixed with MacWise 20.1.5 with compatible code signing and notarizing.

The current version of MacWise is here
