![]() This chain validation is necessary for the client to trust the site.Ĭertificates not issued by known CA but rather by the server hosting the certificate are called self-signed. It is then up to the client to complete the chain by having the root certificate. When we establish a connection over HTTPS, the web server will respond by providing its site and intermediate certificates. An SSL connection succeeds only if the client can trust the server. Relates to: exceptions like CertPathBuilderException, CertificateException, SSLHandshakeException. Question: How I could configure my truststore (certificate chain)? To diagnose a connection another very useful set of tools are Postman, Fiddler and Wireshark. Successfully connected /usr/java/jdk1.7.0_45/bin/java =/my/custom/truststore SSLPoke 443 SSLPoke examples: /usr/java/jdk1.8.0_60/bin/java SSLPoke 443 Here are examples of how you can test if given Java and its certificate truststore can establish SSL connection with a given server. SSL connection diagnostics can be done with SSLPoke Attlassian’s tool. Openssl s_client -showcerts -connect :443Īdding intermediate certificate to the client cacerts file is the workaround you can use in this case. Server does not provide certificate chain. Аlthough all three certificates are in the output of “keytool -list …”, e.g.: Keystore type: JKS Regarding rfc5246 - RFC 5246: The Transport Layer Security (TLS) Protocol Version 1.2 server must send complete certificate chain. If not trusted then the certificate should be added manually.Īnyway, if a Proxy is used, then some extra configurations should be done by your local System Administrator and the Proxy should be set up to trust the certificate. You should check if the Thawte RSA CA is listed as “Trusted Root Certification Authorities”. That is why SUM Bootstrappers/Installer are shipped with a modified HP-UX java.Īnyway, there are deviations between different browsers and there are cases when a given browser vendor does not trust by default a given CA. Warning: Unfortunately, HP Java does not ship any Root-CAs of ’ GlobalSign ’ yet, so this leads to TLS Handshake issue (e.g. Note: Previously it was signed by: CA – Thawte RSA CA and Verified by DigiCert Inc Please, refer the documentation you can find below. If you add a certificate in this truststore it will be deleted when the JVM is updated. Otherwise this should be manually added.ĭo not use this truststore to store custom (e.g. ![]() The new certificate is now signed by ’ GlobalSign ', while the previous was signed by ’ Thawte '.Ĭertificates issued by any vendor, which is a root CA should be trusted by the JVM and should be found into the default jvm/jre/lib/security/cacerts truststore. To verify that jvm.zip is downloaded correctly run:Īnd it should return the same checksum as set at the server for the given component. Sticking to the above example after downloading jvm.zip it should be ~38.2MB and have a proper sha256 checksum that can be checked from SUM V2 Server. This should download the image component that SUM fails to download. If the above is working and there are network glitches you can try to mimic what SUM fails to do by using this command to download a component e.g.: Thus the Software AG certificate should be trusted out of the box. This is because on your local IE, Firefox and Chrome browsers this CA should be part of the trusted CAs list. This certificate should not be added manually to the browser truststore list. If the connection to be diagnosed is over HTTPS you should be aware that a Software AG certificate is used. In this situation you should contact your System Administrator. If you CAN NOT establish the connection, then the Connectivity Issue is not SUM specific one. ![]() It should return a version like “10.-0623”, which is the current version of the SUM server.Īs for specific ports, SUM uses the standard HTTP and HTTPS ports, so there should not be any need to open ports. You can try to ping SDC with a browser or use cURL: You can test against any arbitrary server you are interested in. Try to reach out the SDC (Software Download Center) server over another, an independent third-party tool like a web browser, cURL, Postman or another. Solutions Question: Which are the Connectivity Diagnostic steps to follow?Īlso: How to do the proper connectivity issues diagnostics and check if we have a SUM-related issue? Check the connectivity to the servers which are part of the SUM infrastructure (i.e. Part One - How to do proper diagnostics of Connectivity Issues. Here we cover a collection of the frequently asked questions about Software AG Update Manager (SUM) related to network, connectivity, proxiesm, and other configurations and troubleshooting. This technical article is targeting anybody who has intermediate technical knowledge about SAG Update Manager (SUM) and some base knowledge about Java certificates and truststores.
