System not listening on Port 443

SUSE Linux Enterprise Server SLES Networking

Hi,

SSL is not working on my testserver any more and I am running out of ideas how to solve the problem.

[LIST]
[]The module apache module is activated Apache/2.2.12 (Linux/SUSE) PHP/5.3.17 mod_ssl/2.2.12 OpenSSL/0.9.8j-fips configured
[] listen.conf is configured to Listen to 443 <IfDefine SSL> <IfDefine !NOSSL> <IfModule mod_ssl.c> Listen A.STATIC.IP.ADRESS:443 </IfModule> </IfDefine> </IfDefine>
[] There is a virtual host for SSL - with SSLEngine On and self signed SSL certifcates
[] Firewall is completely shut down to be sure that this is not the problem
[/LIST]

So everything looks fine - but I can´t access my server via https. No wonder - nmap says:

Interesting ports on A.STATIC.IP.ADRESS: Not shown: 996 closed ports PORT STATE SERVICE 22/tcp open ssh 80/tcp open http 111/tcp open rpcbind 3306/tcp open mysql

So: Any idea would be apprechiated. I think the last time I checked if it was working before I made the Update to SLES 11 SP3 - but I found nothing that could indicate problems with SP3 and SSL.

Thanks,

Rexem

OK, found my error: My NginX server made the trouble, despite it is not configured for Port 443. I still don´t know why, but since I removed NginX from my init.d I am able to use 443 for apache again…

  • The module apache module is activated
    Code:
     Apache/2.2.12 (Linux/SUSE) PHP/5.3.17 mod_ssl/2.2.12 OpenSSL/0.9.8j-fips configured
  • listen.conf is configured to Listen to 443
    Code:
     <IfDefine SSL>
 <IfDefine !NOSSL>
 	<IfModule mod_ssl.c>
 	    Listen A.STATIC.IP.ADRESS:443
 	</IfModule>
 </IfDefine>
 </IfDefine>

Correction - listen.conf is configured to listen on port 443 if the
right conditions are met, namely that SSL is defined and NOSSL is not.

  • There is a virtual host for SSL - with SSLEngine On and self signed
    SSL certifcates

Following on from my comment above, have you set the SSL server flag in
/etc/sysconfig/apache2? Use “grep SERVER_FLAGS /etc/sysconfig/apache2”
to quickly check.

If APACHE_SERVER_FLAGS does not include “SSL” then edit
/etc/sysconfig/apache2 and add SSL between the quotes before restarting
Apache.

HTH.

I’m guessing that NginX was configured for port 443 which it grabbed
thus stopping Apache from listening on it although an error should have
been reported when starting Apache.
