With Putty 0.81 no Windows 11, when I select to log to a file, then open
the session, no log file is created.

The file I chose is in a directory that my Windows user has full access to.

Any ideas?

What do you see in the terminal window, or the PuTTY Event Log?

If I tell PuTTY to log to a file in a directory it _can't_ access, then
in the terminal window I see a message such as

Error writing session log (raw mode) to file: z:\putty.log

and the same error message appears at the bottom of the Event Log.

On the other hand, when you _do_ successfully enable logging, nothing
appears in the terminal window, but the Event Log contains a message
indicating successful opening of the log file:

2024-05-03 10:22:47 Writing new session log (raw mode) to file: z:\putty.log

So, which of those do you see? That will tell us whether PuTTY _knows_
it failed to write the file, or whether the Windows API claimed
everything worked fine.

Initially I got no message, then changing what I logged from SSH packets
and raw data to just SSH packets it then reported Error writing session log.
I then created a file (to be overwritten) and checked the security on
it, and the whole tree. Same result.

I have just tried again, but using My Windows Documents folder. It
created the file, and logged fine. SO in future I will do this

I was initially using a .ssh directory in c:\Users\Chris\ which has
always worked for me before.

Strange.

Thanks for the reply
