Hi Heiko,

We finally managed to get it working, but it took running the -MCPAN... to
get it to install.  Despite what the documentation says, the autoinstall
grabbed a whole bunch of other modules, various Crypt modules, BigInt etc..
Must have been about twenty in all.

I'm using Perl 5.8.5, so I didn't need the patch you recommended.

Got my first script running, while writing and testing the various features
of SSH2 out, I found it to be a little idiosyncratic.  Scripts that only
require one command to be run remotely work very well with the exec and read
commands, but the read and write commands don't like shell at all.  Found
that just shoving stuff up and down the pipe worked better.  Also watch out
for the timeouts, on a slow network connection the "while <$channel>" method
will return before it receives a response.  Tried to find a way that I could
detect the response before trying to pull the bits back (the debug setting
indicated that there was an libssh2 flag indicating bits were waiting, but I
could not find the "poll" setting for it; and yes I tried looking at
"poll->revents->in").  I finally just brute forced it by encapsulating make
my read routine in another while loop that would take the number of seconds
(times 4 for the standard 250 msec. timeout) and reenter that number of
times, unless it received a response, when it would just break out of the
loop.  Works great for multi-line responses.  Also, while I was messing
around with the poll settings, I had to set the poll setting every time I
wanted to issue or receive a command or they reverted back to their default
values, unless I'm missing something.

Thanks for the help.
Sincerely,
Ken

It works for me with libssh2-0.18 (as far as I remember Net-SSH2-0.18
was released to address changes therein) and libssh2-1.0, both on
Solaris 10 (64Bit) and Linux (32 and 64Bit).

I have not tested with OpenSSL 0.9.8j (0.9.8h was the latest I used, I
think, on one of the installations).

If you use Perl 5.10 you need to patch Net::SSH2 (cf.
http://rt.cpan.org/Ticket/Display.html?id=37045) but it does not sound
as if you were running into that problem.

Never saw anything like what you describe ("could not find two
OpenSSL .h files during 'make test'").
