that not in the Apache distribution. They are running fine so far. Now we want to migrate
Apache to Redhat Enterprise server v5.7. I compiled Apache the same way and same option as
on the Solaris through a script that I saved. I copied all the modified necessary configuration
files from Solaris and certificates from Solaris to Redhat and made necessary changes such
as IP addresses. The syntax check is OK. When I start Apache on the Redhat, "apachectl start"
just sits there without giving back the shell prompt. The access log and error log are empty
so I don't know the reason. If I disable httpd-ssl.conf file which will not start https, Apache
starts fine. Does anyone know what could be for ssl problem on Redhat?

Maybe not enough entropy on /den/random or /dev/urandom whatever is used?

> Also I first compiled openssl 1.0.0f on Redhat, I then downloaded openssl 1.0.0g once
it became available and compiled it at the same location. On Solaris if I restart Apache,
the error log will show the new version of Openssl but on Redhat, Apache shows the old version
(1.0.0f) of OpenSSL. Why? Thanks.

Solaris doesn't have OpenSSL 1.0 linbs installed in the default lib 
directories, so mod_ssl will find your custom build one. RedHat comes 
with OpenSSL 1.0 installed, so you have to set LD_LIBRARY_PATH or link 
statically into mod_ssl in order to let mod_ssl find the right OpenSSL lib.

If there is other stuff in your Apache which also has dependencies to 
OpenSSL, like e.g. something doing ldaps, then things will become quite 
tricky :(
