Topic "Can't get "pwd" and promptly dies"

Author Message

First off, hats off to the development team of WinSCP!

If a directory does not have the "read" bit set (e.g. rwx--x--x) and one tries to change into
that directory, WinSCP2 (up to Version #110) dies, complaining it cannot execute "pwd"

Would it be possible so that WinSCP does not die when it can't get its pwd? But instead
trust that the directory one enters is the one that was typed in? In other words, in directories
where permission hasn't been given to "ls" or "pwd", one can still "cd" around without problems.
There seems to be no reason for WinSCP to die.

WinSCP is an incredible product, and I recommend it to everybody! Keep up the good work!

What is you server? I have tried this and I can 'pwd' even if I do not have "read" bit set.

I am having a similar problem with winSCP. I am using opensshd on a windows server, and the terminal it uses is called switch.exe. This terminal does not have a command called pwd. I cannot connect using winSCP because it hangs after the authentication.

Here is a copy of the log file. I tried a hack, by making a batch file called pwd.bat. No luck, as my batch file programmins skills are lacking. Is there any fix for this I can use? Do you recommend anything? Thanks for your help, I'm pasting the winSCP log if you'd like to look at it.

WinSCP does not work with switch.exe. You must specify /bin/sh directly on Shell tab of login dialog.

That work on a windows server (/bin/...)? or I shall specify a command shell or \cmd or something like that?

OpenSSH for Windows has /bin, /etc and similar directories (they are virtual).
