iTerminal Pro – SSH Telnet 4+

This is a handy utility; however, it uses an old algorithm which has some vulnerabilities. In some cases, depending on how recent your server is you may not be able to connect.

Connection attempts to servers using OpenSSH 7 or better will produce the following error:

Unable to negotiate with legacy host: no matching key exchange method found.
Their offer: diffie-hellman-group1-sha1
Please update to your app disallow the use of the following protocol:
KexAlgorithms: the key exchange methods that are used to generate per-connection keys

Good app, I would have give more stars but I feel there is some important features or users customizable things available. I’d like to be able to work in portrait orientation and be able to cutomize a bit more the bg and fonts color to my liking :) and customize function keys ... Still it’s a nice app but for the price it should include a bit more.

This app looks good on first glance but it’s shortcomings become annoying in a hurry. The app seems very limited in it’s key exchange abilities. I deal with hundreds of different servers in my work and would love this app if it worked seamlessly with all of them. Lots oF key exchange errors for no apparent reason. Poor support for the later versions of ssh (7).
The UI has some quirks that puzzle me. As a professional programmer since 1978, I have seen many products like this over the decades that fail because of one or two quirks that you just can’t work around. The first and most obvious quirk is that there is no way to have the whole screen for terminal window with the keyboard enabled. The app puts an annoying button bar across the bottom of the screen whenever the keyboard is enabled. This “feature” take up 3 text lines at the bottom which means that your command prompt is hidden behind the button bar and therefore invisible (a unix showstopper).
Further, the terminal seems to have some screen formatting issues. As an example: executing a simple ‘’top” command to Debian 12 displays a fractured and segmented output that makes the screen very difficult to read. Other UNIX utilities display incorrectly as well but some display correctly.
If if this is the developers idea of a well implemented terminal client then they should go back and study product testing before they release this “computer club” attempt to produce a real product. Very disappointed overall. Would not recommend this app to anyone whoo has to use it to get real work done. Sorry
