Hello everybody, I recompiled the newest "traditional" versions of OpenSSL and stunnel on Solaris, Linux, and HPUX. None of the defaults were changed except for --prefix and --openssldir/--with-ssl and --install_prefix Simple tests went through without problems on Linux and HPUX. For Solaris I have a big problem. Any help is appreciated, for example a trustworthy Stunnel-3.26 binary statically linked with OpenSSL 0.9.6m for Solaris 2.6 could also help. Summary ======= Stunnel listens on host medusa 12480 for SSL and forwards plain HTTP to apache on another host (sirius). When I try a HTTPS request to medusa:12480 using a browser or wget, the connection is broken immediately. When stunnel runs under the system call tracer truss the same commands succeed most of the time. In the truss output one can see an EAGAIN on the -r socket of stunnel. That might indicate that there is a problem when TCP buffers do not fill quickly receiving on the -r side.
