I have an up-to-date Ubuntu 12.04 server running Apache 2.2.22-1ubuntu1.4.
For every HTTPS request my Apache logs record what appear to be error messages related to encrypted connections.
Self-signed certificate was generated based on instructions from Ubuntu 12.04 » Ubuntu Server Guide » Security » Certificates
Qualys SSL Labs shows no problems with the server config(other than self-signed cert).
Relevant section of Apache config is:
<VirtualHost *:443>
ServerName site.domain.net:443
...snip...
SSLEngine on
SSLCertificateFile /etc/apache2/ssl/apache.crt
SSLCertificateKeyFile /etc/apache2/ssl/apache.key
SSLProtocol all -SSLv2 -SSLv3
SSLHonorCipherOrder on
SSLCompression off
</VirtualHost>
Error logs are showing entries similar to this:
[Wed Feb 19 10:47:01 2014] [info] [client xx.xx.61.4] Connection to child 2 established (server site.domain.net:443)
[Wed Feb 19 10:47:01 2014] [info] Seeding PRNG with 656 bytes of entropy
[Wed Feb 19 10:47:01 2014] [info] [client xx.xx.61.4] (70014)End of file found: SSL handshake interrupted by system [Hint: Stop button pressed in browser?!]
[Wed Feb 19 10:47:01 2014] [info] [client xx.xx.61.4] Connection closed to child 2 with abortive shutdown (server site.domain.net:443)
Browser is not hitting Stop button as the log implies.
Why am I getting these errors, what do they mean and how to stop them?
