Windows 10 Pro 1803
KiTTY 0.71.0.5 Portable (both direct and from PortableApps)

Anytime I try to launch any session, the ssh window will open, and as soon as it receives any focus/input from cursor or keyboard, it just closes, no errors, no 'crash' but the process ceases to exist anymore. I scanned the registry and didn't find any entries for KiTTY outside of the windows' built-in "most recently used" type entries.

PuTTY still seems to work just fine.

None of the 0.71.0.5 builds work (kitty, kitty_portable, kitty_uncompressed), all plagued with this same issue.

Let me know if I can provide anything to help track this down.

It seems that with the release of Windows 10 1903 kitty sometimes hangs when opening a session: the terminal window opens unresponsive (and is empty), and after a few seconds it proceeds as you would normally expect.

Secondly, when losing a session, it previously was possible to use any key to reconnect, but it does not seem to respond to that anymore (it actually warns when closing that the connection would still be activity, while the taskbar icon clearly indicates the connection is no longer there).

Hi,

My scenario is to use kitty as a tunnel initiator from the host. While having autoreconnect set up the kitty will hang on a error message window and won't reconnect.. E.g. if there is a short network disconnect, error will say it cannot resolve the host and requires manual confirmation in order to proceed and then it will autoreconnect. It is counterproductive and there should be another check-box to suppress any kind of errors and just try to reconnect in a infinite loop.

This would be much appreciated, thanks Michal

Connecting to a local VM via ssh, this is what I normally see on 0.70:

and with 0.71RC3Portable, I get this:

Is that big left indent correct? I presume its due to the fixes on the security side of things. Login to a different machine with public key rather than password looks better:

Initial testing from here on, the terminal looks OK, including running things like ncdu and glances.

Some of the servers I need to access have 2 factor authentication enabled. Which means I get a 'password' prompt and after a successful verification of the password on the server side, I get a 'verification code' prompt.
KiTTY is automatically sending the password on the verification code prompt and thus does not give me the chance to enter the correct verification code.

I found a workaround to that misbehaviour by userpasssshnosave to yes in the registry which (I guess) completely disables the automatic resending of the password.

Furthermore I tried to fix that misbehaviour in code by checking if the prompt starts with the phrase 'Password' and only automatically sending the password in that case, but I guess depending on the actual server configuration this will not work for anyone. So I'm wondering how this problem was solved in earlier versions of KiTTY (where this was working properly!)

My changes which, fixed the problem for me can be found at https://github.com/strguntbr/KiTTY (but please note that I have not been writing (or even reading) C++ code in the last ~15 years, and I was just playing trial and error to get it working for me - please don't convict me for those changes, in case they are complete bullshit ;)

Hello,
There is a problem with auto-reconnect function in 0.71.0.2.

If I put my PC to sleep and it wakes up, connection is broken, but looks like it's not detected, as in menu I can only see option to duplicate session, but not to restart session.
Hence clicking or pressing keyboard button does not restart the session.

Strangely, if option to reconnect on system wakeup is enabled, it works.

Previously auto-reconnect was working even without reconnect on system wakeup enabled.

Problem is also mentioned here #22 and here #15 (comment).

I see a new release at github (v0.71.0.7). But if I press "Check update"-button in the program, I see in my browser a page with the text "Your version is up to date" and the address "http://www.9bis.net/kitty/check_update.php?version=0.71.0.6". After 10 seconds page redirects me to the new address: "http://www.9bis.net/kitty/#!index.md" where I see the string "Current version" and the button with the text "Version: 0.71.0.6".

A very strange issue, kitty portable 0.71.0.7p
I use kitty to load a profile and provide a command, e.g.

e:\bin\kitty\kitty_portable.exe -kload e:\bin\kitty\Sessions\host04.local -cmd "ls -lat"

this input is working but using my desired input

e:\bin\kitty\kitty_portable.exe -kload e:\bin\kitty\Sessions\host04.local -cmd "poweroff -p"

Kitty crashes with the following error in application log:

Faulting application name: kitty_portable.exe, version: 0.71.0.0, time stamp: 0x5d39e89a

This was working with an older version of Kitty

I noticed that PuTTY does not work correctly with functions keys, including the Shift, Ctrl or Alt keys (or it's combinations). I mean, like in openssh client.
Even if used "putty" terminfo. Xterm R6 does not help too.
KiTTY too.
It's a problem if you trying to configure some hotkeys for the 'tmux' or 'screen'. Or trying to use byobu in stock.

I implemented keyboard type "Xterm New" for PuTTY, after studying sources and some info)
You can find patches in my repo.
Also, I send these patches to PuTTY devs.

I think it should be good solution for people who want to use tmux, screen or byobu, for example.

Sorry, I hurried with this. Can be deleted.

Hello,

I'd like to migrate from putty to kitty thanks to the excellent features it provides .. but I'm using plink.exe as a daily driver.

I did not see klink.exe in the documentation. Does such tool exist ?

• WHAT: Current wiki is enabled but only to project members.
  

• WHY: Just a suggestion so others(end users) can contribute notes about kitty.

This issue happens with kitty portable version 0.72.0.3p, but not using 0.70.0.10p.
When I enable "Logging" as "SSH packets and raw data" and uncheck "Omit known password fields" (to recover a forgotten password : ) ) and lauch the session, kitty crash immediately.
Same with "Omit known password fields" checked.
Log file contains only this three lines:

Event Log: Looking up host "nn.nn.nn.nn" for SSH connection
Event Log: Connecting to nn.nn.nn.nn port 22
Event Log: We claim version: SSH-2.0-PuTTY_KiTTY

where nn.nn.nn.nn is the host destinantion address.

Hi,

After the first release of the KiTTY 0.71 I want to open this issue to discuss about the ZModem support.

First of all, I need to comment that I feel this functionality really needs a rework. For example, the configuration values don't need to be associated to a Session, but to the Global configuration (.INI file/ Registry).

Second, I like to help in restoring this functionality into the current code. So, please comment the compiling errors or troubles in the integration.

Regards.

it apiers only with the 0.71 version the Build option NO_SECUREZEROMEMORY is set.

Hello,

is it possible to accept all host-keys without check ?

We have a scripted setup of some devices. They have same IP but every device a new hostkey

Best wishes

Hi,

I think this is somehow related to #23.
I use the portable version 0.71.0.5p and if I loose my connection (happened during trouble shooting sessions with a server) I can reconnect but then I'm not able to fill in my password (using cert with password phrase). It seems that keyboard input isn't recognized any more (even a plain Enter doesn't work).
Workaround for now is to duplicate the session (which is not really the desired way). It worked before with old versions.
If you need more info please let me know...

Hi,
Today I tried to download a new version of KiTTY and none of the download links seems to work. I end up getting same 404 page

P.S. Captcha in feedback form is also broken so I have to put my issue here.

On Windows 10 x64 putty_portable.exe is crashing. Tried on several different computers. Reverted back to previous version and it starts fine.

Faulting application name: kitty_portable.exe, version: 0.72.0.0, time stamp: 0x5d752237

Faulting process id: 0x1904

Might be related to DEP? When I made an exception I was able to get it to run, once.

The new KiTTY 0.71.01 version auto-login behaves differently now. When I attempt to login to a Cisco device the password seems to be sent to the prompt - if I hit the Enter key the login is successful. Before the prompt would read "Send automatic password (Using keyboard-interactive authentication)" and get a hostname prompt.

Hi
Since this is more liberal version of Putty. I like to suggest adding authenticaion via remote ldap or Active directory server. I am no C/Windows coder myself. Just a wish ;)

There are some PuTTY forks which support zooming the font size using <ctrl> + mouse-wheel, e.g. PuTTYTray. I would love to see this feature in KiTTY as well. It is quite useful when using KiTTY in presentations and tutorials.

Hi @cyd01 ,

I suggest a small change in the Menu Item order for better usability:

---
User Command >
Send recorded script file
---
Special Command >
---
Event Log
Export current settings  [new pos.]
---
New Session...
Duplicate Session
Restart session          [new pos.]
Saved Sessions >
Change Settings...
---
Copy All to Clipboard
Clear Scrollback
Clear log file
Reset Terminal
---
Full Screen
Print clipboard
Send to tray
Always visible
Protect
Roll-up
Font settings >          [new pos.]
---                      [new]
Send script file
Send with pscp
Start WinSCP
Port forwarding

Just not working in KiTTY

Malwarebytes is detecting Malware in the binaries. :(

Would it be possible to display pinned/recent items in the context menu for KiTTY shortcut in Start Menu? Just like other programs do, Pageant for example:

When in a session window, the context menu/right-click keyboard key seems to have no effect, which would be okay except that Alt + Space to bring up the standard program menu also fails when shortcuts=no is set. Can this combination be re-enabled with a separate preference, or just exempt from the shortcuts one?

When a KiTTY window is minimised, the title gets reset to either the title it first set upon connection (usually “hostname - KiTTY”) or the one that was current when the settings dialogue was last opened.

E.g., when bash's PROMPT_COMMAND is set to show the current directory in the title, this is cleared to the above upon minimise. If the window settings are opened while it is set to a directory (and that dir. is then shown in the settings' window title), then that is the value to goes back to in the future when minimised (even if apply isn't clicked to close the dialogue).

Hi
kitty_portable.exe
and
kscp.exe
starnge behavior on Win10
on last and some previous builds

sometime during the last updates, Kitty stopped using Putty's Pageant.
I'm running Kitty under Wine Windows7 (32bit)
fwiw: Winscp does see and use Pageant so keys are ok & working.
tried to use kitty with -runagent and that doesn't work either.
Anyway I can help debug this?

PS: Also tried using your kageant.exe - no luck

Just noticed that Putty 0.71 is now out.

Just thought I would let you know.

Running on Windows 10 Pro 64-bit.

After logging in and creating terminal history (e.g. cat a long file), my desktop becomes very unresponsive (windows stutter whilst moving them around, etc.). The whole machine appears sluggish, but nothing shows in task manager or performance monitor (CPU usage hovers around 5%, and memory is at 43%). All windows are affected, not just KiTTY. On closing the KiTTY terminal, everything is restored to normal.

Let me know if you need any more details.

Hi,

In the version 0.70 I use a lot the function "reconnect with a click". However, in the version 0.71 this function is missing.

Any idea?

Currently using portable version v0.71.0.1 with Windows 10 1903
Starting kitty portable without command line option -> works
Starting kitty with -kload (e.g. C:\kitty\kitty_portable.exe -kload C:\kitty\sessions\test) -> app crashes

Using v0.70.0.10 -> -kload works...

Hi @cyd01 ,

I detected this problem with the last version 0.71.0.6p... and I feel it's best to describe how to reproduce it:

• Open KiTTY and start a saved session.
• When the password login is shown, then open the Pageant and Load a key for this server.
• After that select "Close+Restart"
• The you get an error window: KiTTY Fatal Error: User request session restart...

The expected behaviour is that: as you've forgotten to load the key before, then you try to restart the session after... but the current behaviour of KiTTY is to trigger this error instead of restarting the session.

Please, can you fix this incorrect behaviour?
Thank you for this amazing PuTTY fork!

Using 0.71.0.6, when connecting to a host, I receive the following error message:

Assertion failed!
Program: k:\bin\kitty\kitty.exe

Hello,
every time i put my windows 10 on hibernation, then power on, the active kitty windows to a specific server show a popup "unable to open connection to XXXX host does not exist".
If i click OK, the windows auto reconnect without problem, and it doesn't happens with other domains.
I can't unfortunately give you the domain, but it's a subdomain on debian, hosted on cloudflare (with the subdomain pointing to the real server of course)

Hello! Can we get some usage guidance or docs for klink.exe, the command line tool? Does it have all the features as KiTTY? Does it have the auto reconnect features? I understand i can make it use the same kitty.ini file, but cant seem to get the reconnect feature work somehow.

Thank you!

For example if I have 2 or more monitors and the current active window of kitty is on monitor 2 which is not the main display (monitor 1) defined by Windows, the full screen mode will automatically render the active kitty window back to monitor 1. And there is no way to make kitty full screen on monitor 2. I am using kitty 0.71.0.7.

Putty does not have this problem actually.

• WHY:

  • Enterprise user expect .msi to push out and maintain binary.

• HOW;

  • Hope I don't have to do it myself but if no taker, this is something I can work on as sysadmin doing occasional packaging for Windows.

• Reference:

  • R1: https://wixtoolset.org/

If 2FA is enable (with Google pam for example), you are unable to type the verification code.
Works fine with Putty, maybe just a settings ?

Screenshot : https://ibb.co/Vg57p3g

The “Check for update” button opens the page with the address: “http://www.9bis.net/kitty/check_update.php?version=0.71.0.5”. And my browser shows a blank page with the title "403 Forbidden", the h1-tag "Forbidden" and the text "You don't have permission to access /kitty/check_update.php on this server."

I reported this during the beta for 0.71 but it's still present in the final release.

When using the normal (non-portable) version, the main dialog is cut off at the bottom right-hand corner (and the window cannot be re-sized). I was told this was due to the "Folders" drop down and this could be disabled by adding "Folders=Default" to the registry. This doesn't seem to work, however.

In the portable version, adding "Folders=Default" to the kitty.ini file does work.

Git and mercurial stopped working when v0.72.0.1 is used.
Versions v0.71.0.7 and older working.

Hi,

I need some help to setup the development environment.

Hi, is KiTTY also hit from current bugs found on PuTTY?

https://lists.tartarus.org/pipermail/putty-announce/2019/000027.html

Since the forum seems to be closed, I'l post this here. This is an enhancement request, and a suggestion for a workaround to get syntax highlighting. Very handy when configuring routers and could also help when looking for certain text in logs.

In current versions of Kitty, you can (mis-)use the URL highlighting feature to underline words

My example pattern highlights Enabled, Up, Down and IP addresses:

(Enabled|Up|Down|([0-9]{1,3}\.){3}[0-9]{1,3})

It would be even better if you could have a list of regular expressions with colours, for example: Up->green, down->red and IP Addresses->blue.
Hopefully this will inspire someone to implement this... the URL highlighting patch is probably a good place to start 😉

Connecting to a new server does not prompt to "cache the server's host key"
It just connects

Hi @cyd01 ,

When sending the BREAK "Special Command", in the first time the size of the font changes (and the window resizes). And the second time the KiTTY process hangs.

Please, can you check it?
Thank you!
