Working on old hp-ux systems, I came over this annoyance. I hope you'll be able to do something about it.

Description: I can't connect using WinSCP on old hp-ux box (ssh1 only, w/o bash) unless I specificly set shell to /bin/ksh. It's annoying and if it wasn't because of a collegue saying that scp DO work on the box I would have never used winscp on it again. Turned out that there is a workaround but I wonder if the shell could be autodetected. Forgot to tell that this user's default shell is /bin/ksh in /etc/passwd.

version 3.7.6
protocol SCP

Here's the log when Shell is Default:

Can't you find it using the $SHELL environment variable?

I guess you actually already need a shell to check that but maybe once inside one and you find that it's ksh then you use whatever code is used when I explicitly define /bin/ksh in scp conf.

I guess it's not that simple. Confused

No it's not Smile
Really, I do not plan to do such a changes in SCP code anymore. It works the best way I can do it and SCP is really legacy protocol only. I do improvements only to SFTP mostly.
