[jira] [Created] (SSHD-149) Is separation of sftp subsystem
interfaces possible?
Is separation of sftp subsystem interfaces possible?
----------------------------------------------------
Key: SSHD-149
URL: https://issues.apache.org/jira/browse/SSHD-149
Project: MINA SSHD
Issue Type: Question
Reporter: Stefan Rönisch
We'd like to use the mina sshd sftp funtionallity.
I've to validate, if this product fits our needs.
As far as I saw until now it looks great.
But we've to support some special requirements.
- We have to support a special proxy solution for dmz which handles ssh encryption and authentication. So we need to use the sftpsubsystem without ssh encryption. Unfortunately, there are some method signatures which avoid this.
- We have to manipulate sftp command results in some cases. For example we like trigger internal processes after getting a file, but if triggering the process fails the sftp command result should signal an error.
Is there a chance that our needs will be considered?
And when a solution could be expected?

--------------------------------------
Patches or suggestion are really welcomed. So if you provide more detailed informations (such as a rough draft of the interfaces you'd expect), we can start discussing them more in depth.

Hi, could you roughly say when working on this issue is planned for?

-------------------------------------
Fine, that sounds great.
Until July I have serveral other things in process.
Then when I have time I will think about interfaces useful for me.
Then I'll post it here and we could discuss it, ok?

Stefan Rönisch commented on SSHD-149:
-------------------------------------
Starting from now, I've got some time to engage in this topic.
How, could we start discussing, best?
My current status, in headwords:
- I've implemented a main part of my requirements with modified apache-sftp classes and work with it.
- I've used local modified copies of apache-sftp with minimal changes to identify the differences.
- I've written proposals of additional general classes and interfaces to support the kind of my requirements.
Requirements:
- Virtual user filesystem
(hide other directories and support system independ users, like in apache-ftp-server)
- Support customized command handling.
(used for logging, triggering application specific events, signaling application specific errors by modifying reply codes)
- SFTP without SSH encryption
(special requrirement for proxy support - until now not it the proposal classes/interfaces - just in progress).
Here a litte bit to my requirement background.
My application supports servers to transfer files with different filetransfer protocols. (FTP, FTPS, SFTP, ...)
So, I don't need the full ssh-server functionallity. Just SFTP-transfer and later on SCP, too.
The user view should be the same, as far as possible.
My class and interface proposals depends on sshd-core 0.6.0.
