Royal Apps

For a while now, I've had recurring problems with the PuTTY integration. When it works, PuTTY is launched and RoyalTS encapsulates it in a tab as it should. When it fails, I get a separate PuTTY window, and RoyalTS thinks the connection has failed, but the PuTTY window works fine (logs into the server and works as normal) - just not inside RoyalTS.

This problem started gradually over multiple RoyalTS versions. Now, it happens almost every time I launch an SSH session - from a connection in the document, or duplicating a tab.

This happens on multiple Linux servers - RHEL7, RHEL8, and Debian 12. Oddly, it rarely (if at all) happens on my Opnsense box (FreeBSD). (One difference I can see beyond the remote OS is that my Opnsense box is a "static" connection, where all of my other servers are in a dynamic folder.)

I am on latest RoyalTS on Windows 11. My PuTTY plugin settings are the default, except for the embed method (set to Window - I have tried Client Area with no change, and the PuTTY cursor not being focused when using Client Area is a distraction for me).

I am using the PuTTY shipped with RoyalTS. In my PuTTY session, I do not have a custom window title.

Happy to share more info or any required logs. Appreciate any insight into what is going on.

I noticed the same behaviour after the recent RoyalTS update. I use the same Document with Connections on another machine, also Windows - where this behaviour wasn't occuring.

I noticed that I didn't get the "known hosts" warning for this connection. I cleared the content of "Computer\HKEY_CURRENT_USER\Software\SimonTatham\PuTTY\SshHostKeys" with Regedit, where the known_hosts for Putty are stored. When this was cleared, after accepting the warning permanently, I got the Putty window embedded in RoyalTS. But after that, it loaded outside again in a separate Putty window.

The Connection has a Credential Name set, which points to a Credential "ssh key" in another Document with Credentials. This Credential "ssh key" has username set and path to a private ssh key in .ppk format. 

It seems that which such hosts as soon as the connection is accepted and is stored in Registry Key above as a known host, the Putty window is launched externally. While if I select "Allow once" at the Putty Security warning, Putty is embedded in RoyalTS.
