It is same as what we have done using UI in earlier step.įor SSLCipherSuite, I have used site to generate Apache Cipher with “Old” configuration. SSLCipherSuite above line, we are instructing Apache to enable all protocols except SSLv2 and SSLv3. If you see SSLProtocol and/or SSLCipherSuite, replace those lines with following. Go to Webmin > Servers > Apache Webserver > Global configuration tab > Edit Config Files > select etc/apache2/nf Make sure you follow the above steps for ALL SSL enabled virtual servers because SSL settings across different virtual servers are somehow affecting entire Apache server. Go to Webmin > Servers > Apache Webserver > Existing virtual hosts tab > YOUR_VIRTUAL_SERVER:443 > SSL Options > SSL protocols > Tick TLS v1.0, 1.1, 1.2, 1.3 and Untick SSLv2 and SSLv3. Enable Older TLS Version Using WebminĮnabled TLS 1.0 and 1.1 from Webmin UI. After researching for days and reading lots of threads, here are the things that worked for me. Enabling older TLS version is not a straight forward path. It seems like Windows 7 can work only using TLS 1.1 or TLS 1.0, the application stopped connecting to the Website. If you have a server upgraded from Ubuntu 18 to Ubuntu 20, it supports recent and older TLS. After researching, I found out that in order to increase security, Ubuntu 20 supports only TLS 1.2 and older TLS are disabled by default on new installation. I figured out that there is something wrong with the SSL connection and hence the application cannot connect.Įven though my old and new servers are Ubuntu 20, somehow both support different SSL versions. If the application is running on Windows 7, it cannot connect to the Website but if the application runs on Windows 10, it works. Net application that is connecting to the my website. Topic: How to disable weak ciphers in Apache Tomcat 8.5.When I migrated a site to a new Ubuntu 20 server, I faced an issue. To use only high-secure-ciphers you may visit īut keep in mind that you might have some old clients that cannot use the most modern ciphers. Stripped my config down to this (still working ) version - now tomcat is not complaining about deprecated options/settings anymore: ![]() Posted: Fri 28 Dec '18 21:07 Post subject: Are the ciphers you are using the strong ciphers or a list of all weak and strong? I translated those into 8.5 but am still having issues. Posted: Fri 28 Dec '18 0:15 Post subject: Still not workingįrom what I found most of those commands were deprecated after 5.5 I believe. On my test-server I run this configuration which might be used as a blueprint for your configuration: Posted: Sat 22 Dec '18 11:24 Post subject: Location: Schömberg, Baden-Württemberg, Germany Here is a copy of our scrubbed server.xml I want to know where in the connector settings do I put the ciphers and what other options are needed to block weak ciphers? I appreciate any help you can give. I have tried several different ways to add ciphers and lists of weak ciphers but when I run a scan I still show them being weak. This system is running on a Windows Server. I am being pinged by our security folks on scans stating that we still use 3DES ciphers.
