Information in this document applies to any platform.
This issue appears when trying to connect to EDQ file server by using sFTP with Filezilla tool (our version is 3.23, but this issue appears also with the most recent filezilla versions).
When trying to establish a sFTP connection, the error below occurs :
"The first key-exchange algorithm supported by the server is diffie-hellman-group1-sha1, which is no longer secure. Aborting connection."
Regarding our EDQ configuration, please find information below:
- EDQ version: 22.214.171.124.0(130) - 3 oct. 2016 20:45:37
- Apache Tomcat/8.0.23
- Linux OS Version: 2.6.32-642.11.1.el6.x86_64
- Java Version: 1.8.0_101-b13 (Oracle)
It is noticed that diffie-hellman-group1-sha1 key-exchange algorithm is not supported by the new Filezilla version.
The key-exchange algorithm in the tomcat configuration (server.xml) is to be kept
Using a new version of filezilla FTP/sFTP tool an issue with EDQ environments occurs.
