I stand corrected with Jsch API support for owner and group details. Currently
Jsch API return 0 for UID/GID in line with their documentation
{quote}
Please note that they return +_integer_+ values - which is all one can do in
SFTP v3.

Is there a way to know server O/S ?
{quote}
There are a number of +heuristics+ one can use - basically it involves running
some commands and attempting to see if they succeeded and if so parse their
result. E.g. (for Linux) {{uname -a}},
> Posix file owner and group always null
