Very long time user of Tramp; depend on it heavily.  Thanks for awesome
software!

Tramp is not working any longer with Solaris hosts it worked with previously.  
It seems to be fine with Linux hosts.

Started with emacs -Q

Recipe:
C-x C-f
/ssh:sybase@lee:

At this point I enter my password; despite entering it correctly, it
prompts a second time for the password.  I provide it again, and then
the connection fails with the message you'll see below.  The transcript
from my messages buffer:

Tramp: Opening connection for sybase@lee using ssh...
Tramp: Sending command ‘exec ssh -l sybase  -o ControlMaster=auto -o ControlPath='tramp.%C' -o ControlPersist=no -e none lee’
Tramp: Waiting for prompts from remote shell...
Tramp: Sending Password
Tramp: Waiting for prompts from remote shell...done
Tramp: Found remote shell prompt on ‘lee’
Tramp: Opening connection for sybase@lee using ssh...failed
Tramp: Opening connection for sybase@lee using ssh...

Tramp: Found remote shell prompt on ‘lee’

Thanks for any help!

There have been many discussions which value to set for
`tramp-histfile-override', see for example
<https://debbugs.gnu.org/24478>. Unfortunately, there is no proper
default value satisfying everybody.

The error message means, you shall change the default value of that
variable.

Best regards, Michael.

Thanks for the reply.

The trick I missed is that this variable needs to be fixed in two places: tramp-sh.el AND tramp-loaddefs.el.  It now works for both Linux and Solaris.  Specifically, I had to set the value
Old: ~/.tramp_historyNew: .tramp_history
I had had some success in older versions of Emacs by changing the tramp-sh.el file only.

Again, thanks for your help.

Tom

There's no need to patch Tramp files for this. `tramp-histfile-override'
is a user option. You could change it in your .emacs:

(custom-set-variables '(tramp-histfile-override ".tramp_history" nil (tramp)))

That worked.  Thanks again - you have saved me hours of time.
