Subject Re: How to change directory while using sftp component
Date Sat, 02 Oct 2010 15:46:45 GMT
Hi

I will try to reproduce the issue with the help of Apache SSHD as
simulating the SFTP server. It's not like a real server but it may
help and in the future catch regression bugs.

I got the first simple test up and running by uploading a file.
