Rob,

Are you certain that your failing script uses the very same libssh2 library ?

I am using CGI pages under same environment. So I believe I am using same libssh2 library.

I don't see anything in the subroutine you posted that should cause that error, so it probably happens before that sub is called.

$ssh2->connect($rip)
[download]

This is the code that is failing. Same parameters, same environment, same script. Not sure how to proceed on this and why it is throwing -43LIBSSH2_ERROR_UNKNOWN(-43)Failed getting banner error?

Thanks,
Ashok.
