RE: [dsdp-tm-dev] Extending RSE

[David McKnight <dmcknigh@xxxxxxxxxx>]

Hi Sheldon,

There is another alternative for an
agent if you don't mind using java on the server-side.  You could
use the dstore, which is part of RSE.  To do this, you would need
to download the dstore server runtime from the TM RSE download page and
put it in a directory on your host.   There the archive needs to be
extracted and then the daemon script should be run by an admin before clients
can start connecting.

Hi Sheldon,
 
Usually telnet is used for terminal
/ shell like connections only, but not for
browsing or transferring files.
 
My first recommendation to you
would be to try and get some sort of file
transfer protocol running on your
target. There are really really small 
servers and agents available.
 
If that's not possible, but your
target has some kind of shell that supports
shell commands like "ls",
"dir", "chdir", etc. you can implement your own
remote file system browser through
telnet, by mapping an RSE IFileService
request like getFiles() by executing
such remote shell commands, parsing
the ASCII output and returning
IHostFile instances as needed.
 
You'd still have a hard time transferring
binary files, though, because the
telnet protocol cannot easily
transfer binary data (so when you do e.g.
"cat remoteFile" in
order to transfer it to local, this would be unreliable
for binary files). You could try
and get around this by running a program
like uuencode / uudecode on the
remote side, or having an xyzmodem
server (see https://bugs.eclipse.org/bugs/show_bug.cgi?id=165893).
 
I hope that helps, and I'm looking
forward to hearing about your
progress...

Cheers,

Hi Martin,

             I am currently using SSH as
a blue print for creating the telnet service as you said, but i have come
across a problem. In the SSH there is a File service implementation for
SFTP, but the targets which i will be connecting to are not going to support
protocols like FTP, TFP . So is it possible for me to have RSE for the
target where a user can browse the entire target file system using telnet
without a file transfer protocol, because i guess protocols like FTP are
only used for various operations on files. 

Regards,
Sheldon

Hello Sheldon,
 
A Telnet connector service / shell
subsystem does not exist yet.
You can basically take the org.eclipse.rse.*.ssh
as blueprint for doing it,
and replace the ssh service (based
on Jsch) by a Telnet implementation.
 
For a telnet implementation, you
can choose from Jakarta Commons Net
(which is already part of RSE),
and the implementation in 
org.eclipse.tm.terminal/src/org.eclipse.tm.terminal.internal.telnet
(which is discouraged API so I'd
rather recommend Commons Net).
 
When you come up with a telnet
connector for RSE, we'd appreciate
if you could contribute it under
EPL!

Thanks,

Hi,

               I have tried RSE ant
it works well for protocols like FTP and SSH. I would like to use Telnet
as the underline subsystem does it exist or do i have to extend RSE to
support telnet.

               If so how do i exyend
RSE to support Telnet protocol? 

Regards,
Sheldon
