Re: [Dev] [Architecture] VFS and SFTP

2016-01-13 Thread Vijitha Ekanayake 
Hi John,

Can you try this by providing IP address of the SFTP server instead of SFTP
server’s hostname in parameters.

In your proxy we specified the VFS endpoint by giving the host name
(instead of the IP address). Then, you might come across the exception (Could
not connect to SFTP ) as you mentioned in your mail.

Apache Commons-VFS [2] uses JSCH [5] for its underlying SSH layer. JSCH
uses the location $HOME/.ssh for the known_hosts file by default.
Eg. location is $HOMEPATH/.ssh

Therefore, since the host that you are trying to connect with is not in the
known_hosts file, Synapse has no idea whether the SFTP hosts can be
trusted. Therefore, we need to add the host to the known_hosts file.

Solution has been suggested in article[1] to overcome this issue.

Thanks,
Vijitha.

Hi John,

You can also try the File Inbound [1] which is a new feature released with
ESB 4.9.0.
