Hi:

On the various repo sites for Redhat-CentOS-Oracle Linux, etc., they are only providing version 4.29 of stunnel. Is there anyway to push them an updated version?

I normally use these repo providers:

Oracle Linux repo EPEL 6 Repo rpmforce Repo

Unfortunately it does seem that stunnel-5.x is not available through any of the official and even semi-official package repositories for CentOS 6.

In the end, I tried to compile the latest version on Linux but I get this somewhat cryptic message about a TLS installation directory. I never had this issue before but to be honest, I normally used Solaris (8-9-10) in the past.

"Could not find your TLS library installation dir Use --with-ssl option to fix this problem"

I tried pointing it at /usr/bin/openssl and also at /usr/lib64/openssl without any luck.

To compile programs that use a library, you need not only the library files themselves, but also the so-called header files that describe for the compiler what functions and data types are defined and used in the library. Most Linux distributions keep these files in a separate package, e.g. on CentOS 6 for OpenSSL there is the "openssl" package that contains the libraries themselves and then there is "openssl-devel" with the header files. Try installing the openssl-devel package and rerunning the stunnel configure script; it should be able to pick up the OpenSSL header files without any special --with-ssl options, it knows where to look for the most common installation directories.

Hope that helps!
