Subject: Re: [dsdp-tm-dev] Extending RSE
I just wanted to know that if i put FTP support on my target, Then i guess a combination of telnet + FTP should work.
In this case my telnet fileservice will have to just extend the existing FTPFileService, or do i have to add something else.
Regards,
Sheldon

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.

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
