I cannot login winSCP without my own username
I have closed the root login and follow the tutorial in WinSCP document<How do I change user after login (e.g. su root)? :: WinSCP>.
But the WinSCP told me "cannot initailize the SFTP protocol ", then I tried to use SCP to login however it told me the bash was not compatible with the program.
How can I solve it?
