Deven Kalra’s Weblog

I went through a major process to set up an SSL certificate in a web server going through a number of error messages including:

Data Transfer Interrupted

The connection to has terminated unexpectedly.
Some data may have been transferred.

and

(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80

I am using a certificate from GoDaddy and running Apache2 on Ubuntu 8.04.

Not sure what series of corrections fixed the problem but the following configuration is now working:

/etc/apache2/sites-enabled/000-default


NameVirtualHost :443
NameVirtualHost :80

And, the ssl.conf directory (/etc/apache2/mods-enabled/ssl.conf)

SSLRandomSeed startup builtin
SSLRandomSeed startup file:/dev/urandom 512
SSLRandomSeed connect builtin
SSLRandomSeed connect file:/dev/urandom 512

## SSL Global Context

## All SSL configuration in this context applies both to
## the main server and all SSL-enabled virtual hosts.

# Pass Phrase Dialog:
# Configure the pass phrase gathering process.
# The filtering dialog program (`builtin’ is a internal
# terminal dialog) has to provide the pass phrase on stdout.

Hope this helps some other soul having the same tribulations.
