How to Enable Weaker Algorithms in the Built-in OpenSSH Server
Problem
You are trying to connect to the built-in OpenSSH server of IGEL OS with an SSH client which does not support the strong algorithms of the server.
Solution
To enable weaker encryption algorithms, proceed as follows:
In Setup, go to System > Registry > network > ssh_server.
Change the settings according to your requirements:
disable_weak_encryption: Disable this option to enable weaker encryption.
disable_weak_hostkey_algos: Disable this option to enable weaker host key algorithms.
disable_weak_kexalgorithms: Disable this option to enable weaker key exchange algorithms.
disable_weak_macs: Disable this option to enable weaker MACs.
minimal_encryption_level: The minimal level of encryption
