Hello, about the CVE-2015-0204, in apache the following config seems to disable this vulnerability: SSLProtocol All -SSLv2 -SSLv3 SSLCipherSuite HIGH:MEDIUM:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4 Is something similar possible with dovecot ? If yes, what are the implications with old mail clients ? -- Best regards, Adrian Minta

Hi Is there known advices on how to favor PFS with dovecot? In Apache, I use the following directives, with cause all modern browsers to adopt 256 bit PFS ciphers, while keeping backward compatibility with older browsers and avoiding BEAST attack: SSLProtocol all -SSLv2 SSLHonorCipherOrder On SSLCipherSuite ECDHE at STRENGTH:ECDH at STRENGTH:DH at STRENGTH:HIGH:-SSLv3-SHA1:-TLSv10 -SHA1:RC4:!MD5:!DES:!aNULL:!eNULL dovecot does not care about BEAST, since attacker cannot inject trafic. Therefore the cipher list get simplier in dovecot.conf: ssl_cipher_list = ECDHE at STRENGTH:ECDH at STRENGTH:DH at S...

Hi, I'm currently experimenting with a public server running CentOS 7. I have half a dozen production servers all running Slackware Linux, and I intend to progressively migrate them to CentOS, for a host of reasons (support cycle, package availability, SELinux, etc.) But before doing that, I have to figure out a few things that work differently under CentOS. Apache and SSL behave quite

I''m having a problem but don''t know what is causing it so I don''t know exactly where to post, please bear with me. I''m trying to set up https access however whenever I go to https://url_for_site the root route renders but the url is rewritten to http://url_for_site. The ssl request shows in the apache logs but obviously no further ssl requests show up.

Hello, I've got a client who wants to go ssl. He's running a web server, smtp/pop, and ftps and imaps is coming as well. I'm looking for a wildcard ssl certificate i believe it's called but one on the budget plan. I am also wanting to ensure that the mod_ssl with httpd on the server is only using the strongest encryption methods and protocols. Thanks. Dave.

Hi list, I'm configuring apache with https and I've a question about sslv3 deactivation. Running "openssl ciphers -v" I get a list of cypher suite of openssl like: ECDH-RSA-AES128-GCM-SHA256 TLSv1.2 Kx=ECDH/RSA Au=ECDH Enc=AESGCM(128) Mac=AEAD ......... Each lines report relative protocol. Disabling sslv3 with "SSLProtocol all -SSLv3" I can use cypher like:
