---------------------------------------
Summary: Camel SFTP: Cannot configure JSch client to use ssh-dss
key
Key: CAMEL-18264
URL: https://issues.apache.org/jira/browse/CAMEL-18264
Project: Camel
Issue Type: Bug
Components: camel-sftp
Environment: Tested with Apache Camel 3.17.0 and 3.18.0
Reporter: Konrad Stachera
Attachments: image-2022-07-11-10-34-58-099.png
When server requires ssh-dss host key algorithm it is not possible to configure
sFTP camel component to use such key type, therefore connecting fails with
"com.jcraft.jsch.JSchException: Algorithm negotiation fail".
When these two properties are added in debug mode:
{code:java}
session.setConfig("server_host_key", session.getConfig("server_host_key") +
",ssh-dss")
session.setConfig("PubkeyAcceptedAlgorithms",
session.getConfig("PubkeyAcceptedAlgorithms") + ",ssh-dss") {code}
in SftpOperations class:
!image-2022-07-11-10-34-58-099.png!
the connection is established successfully.
It should be possible to configure "server_host_key" and
"PubkeyAcceptedAlgorithms" in camel sFTP component.
