I'm not sure why it's not disabling SSLv3 for you, but another option is to remove all of the ciphers that use CBC. There are a lot of other bad things in 6.0.18 and, probably, the versions of Java being used in these places. The proper mitigation is to upgrade, not to try to configure-around the problem. - -chris > 2015-01-30 22:28 GMT+08:00 Christopher Schultz > > : > > Jason, > > On 1/30/15 4:32 AM, Jason Y wrote: Please refer to https://access.redhat.com/solutions/1232233 > > This link is /slightly/ out of date, in that it is missing > more-recent information (i.e. support for TLSv1.1 and TLSv1.2 in > tcnative versions after 1.1.21. > By the way, why would you disable SSL?

Hello Jason, Chris, Thanks for you answer and replying. I actually already tired that solution linked in the page https://access.redhat.com/solutions/1232233. but it does not work at all. Yes, this is common problem whatever the tomcat version is, SSL V3 is not safe any more, however, newer tomcat has ready configuration/solution for disable V3. since I am still in old version so I am looking for solution for version Tomcat/6.0.18. but no good luck until now. 2015-01-30 22:28 GMT+08:00 Christopher Schultz : > -BEGIN PGP SIGNED MESSAGE- > Hash: SHA256 > > Jason, > > On 1/30/15 4:32 AM, Jason Y wrote: > > Please refer to https://access.redhat.com/solutions/1232233 > > This link is /slightly/ out of date, in that it is missing more-recent > information (i.e. support for TLSv1.1 and TLSv1.2 in tcnative versions > after 1.1.21. > > > By the way, why would you disable SSL?

Re: How-to disable SSL V3 on Tomcat 6.0.18.0
Hi Jammy, Please refer to https://access.redhat.com/solutions/1232233 When using Tomcat with the JSSE connectors, the SSL protocol to be used can be configured via $TOMCAT_HOME/conf/server.xml. The following example shows how the sslProtocol in an https connector is configured. Tomcat 5 and 6 (prior to 6.0.38) Tomcat 6 (6.0.38 and later) and 7 If the sslEnabledProtocols or sslProtocols attributes are specified, only protocols that are listed and supported by the SSL implementation will be enabled. If not specified, the JVM default is used. The permitted values may be obtained from the JVM documentation for the allowed values for algorithm when creating an SSLContext instance e.g. Oracle Java 6 and Oracle Java 7. By the way, why would you disable SSL? What is your current problem? I may have the same problem with tomcat 7.0.55... On Fri, Jan 30, 2015 at 2:44 PM, Terence M.

I cannot find the solution* Okay, here's the deal: from your perspective, the documentation on Tomcat's site is all out-of-date (into the future) because you (or your customers) are using an ancient version of Tomcat. The best solution is to tell your customers that you don't support your own product on that version of Tomcat any longer. I love that line of crap when it works to my advantage. Anyhow... The "sslEnabledProtocols" configuration attribute was added in Tomcat 6.0.38, well after your 6.0.18 version. Before that, it was called "sslProtocols" and/or "protocols". Give those a try. (Also, there was a bug in the NIO HTTPS connector specifically that it does not recognize the "sslEnabledProtocols" configuration attribute, but that bug was introduced along with "sslEnabledProtocols" in 6.0.38 and fixed in 6.0.43, so the whole thing is moot as far as you are concerned. The "protocols" attribute should work.) I posted some code to this mailing list a while back that will probe a server to discover that types of connections and ciphers it will accept. When you configure your server, consider trying that to see what kinds of connections are possible. Note that it's limited to what version of Java you are using *for the client* as well as the server. So, with Java 1.6, you will not likely have TLS 1.2 available, and many ciphers that the server may support under a newer JVM might not be available in 1.6. I would recommend running the latest Java version you can for the client in this case, because it will be able to try the most options against the server. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1 Comment: GPGTools - http://gpgtools.org iQIcBAEBCAAGBQJUynVWAAoJEBzwKT+lPKRY2lcP/jLvNreb+aY00YhgzAq+Ipii C9lm3lnewamy7dGUGEWE8vgV4Yu5tyzGeb0j6uRvBnHKdp+XEjRfnAuxh1Mx5bqa byw8Fa5rfQ4TbCg5oTZZ3pGAsrBdLZp11P3O3Pxs/oSuzkWObHAlo9VGXaL0oXFB FGgVwZfush/8lfBcF7hRl9tP/QE8/FlVyulKac6BVKdY2Os0crfrLpWyf0N+N2Xh TEgFkwraCdfjy/La2Cudp899k8s/JYq2kRsgRTQ/apYHtbIzCf2B5I32wC0VudOC 9eI3wPnYiM8aR940W5L37cTgDqls+tiifzcodvhyWfO+SiuEayaAJG6KuyIpYFBn ZdDMLcIiA4om+nZcbn1w2n3Hi8VxaPryxHt75Ak9n8FsqSGuEop29cDanbKYJU6P OuK2sAalT6uZCy2GvV/3xGoD7kkvHWmsngsblGSR19nfLr/Y8eS20jho+3YI+pjy hyprA5uKxJAz07iGklx98jq3d33529+FP8jUYtJuP+8jyQenpFhsWd3k6Oh6DeFB MNHU04x7cqOSvtBN+yBe1ZLZVJlEP9eMMVRFpfZwb97I27bxL13FG9IWiMYmMBVj OVaVbm8FqaMtDCjzj36z2PWPLouDRs2kcaEHNYIzp8rsQ9GD0tJTmkxG6XUFDazi cU/f8sS7how+TLnmKycX =nABr -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Hello team, Do everybody knows how-to disable SSL v3 in older tomcat version, I have tried to variety solution including sslProtocols or sslEnabledProtocols but it both did not work well, the Firefox I am using to test is only select TLS 1 and result is that I were not able to access the site.
