What about getting the current directory right after connect? A
pwd()
or
realpath(".")
call should give you the "home directory" right after connect
and thus give you some indication about the remote OS type.
Cheers,

Subject: Re: [JSch-users] Remote OS Name
Thanks for your answer. I am trying to connect to SFTP servers
on different platforms. One of them is on MVS (mainframe). Since the
folder structure for MainFrame is different , I will need to handle that
differently. So I need to know when I connect to a server the OS it is
running on.
Any pointers on how to achieve this??
Thanks

Hello,
It is my understanding that JSch implements the IETF
protocol
standard very strictly. And the sftp protocol standard
tries exactly to get you away from having to know what
OS name or version is running remotely -- since the
protocol
should be standardized and the same across all OS names
and types.
You could look up Sftp on Wikipedia, and the Wikipedia
References will bring you to the official protocol
standard
discussion on IETF:
http://tools.ietf.org/wg/secsh/draft-ietf-secsh-filexfer/
The standard RFC is now at version 13, but it is my
understanding
that there are practically no servers out there in the
wild which
implement the latest standard revisions -- v3 (!) seems
to be the
most widely used revision if I'm not mistaken.
The protocol does give support for querying the protocol
revision
that the server supports, and it does give you a String
identifying
the remote server software (e.g.
"Remote protocol version 1.99, remote software version
OpenSSH_3.9p1"
You can see that version String under "debug1" if you
use a
commandline client, e.g.
sftp -vv myhost
That would be the SSH Server's version, the sftp
protocol version
can be seen with "debug2:" later in the log:
" debug2: Remote version: 3"
Hope that helps,
