Hello,
I compiled our existing SSH file copy program and tried using it
with the current CVS version of libssh2 (from 2009-03-18).
Unfortunately it does not work: the program "hangs" in the library
call libssh2_sftp_init() and does not return. The "sftp-server"
process has been started correctly (and can be seen in the process list).
Aborting the program I get the following stack trace:

"strace" shows the process blocking in "recvfrom(3, ...".
Is this a known problem?
