Some clown made me a sftp username that started with ##.  Now I don't know if the command is wrong or the ftp server isn't responding for certain.  Could someone please confirm for me that this should work using:sftp ##Username@sftphostaddressThank you
Using a username starting ## at a bash prompt
bash;ssh;sftp
Yes, that should work... if your username really does start with ##. If it does, it would have to be the most bizarre username I've ever seen. In other words: are you sure this username is correct?
