DH key size not supported - PowerConnect 5524
Posted: Wed Apr 24, 2024 3:18 pm
Hello,
I cannot get concrete feedback from support for my ticket created on 01/16/2024 so I'm trying my luck here
We recently changed the settings on our Dell PowerConnect 5524 switches to enable SSH instead of Telnet. In the logs we have : “com.jcraft.jsch.JSchException: Session.connect: java.security.InvalidAlgorithmParameterException: DH key size must be multiple of 64, and can only range from 512 to 8192 (inclusive). The specific key size 2049 is not supported”
Is there anything that can be done to correct this, or are these switches just too old and we need to re-enable Telnet for now if we want to back them up via Unimus? We currently have Unimus version 2.4.2 installed.
Thank you
