Thomas Wolf commented on SSHD-1155:
-----------------------------------
We cannot debug your connection problems. One thing I notice is that it says:
client: ...,ecdsa-sha2-nistp*512*,...
server: ecdsa-sha2-nistp521
There are no common algorithms.
Could this be a bug in that Tectia client? ("512" instead of "521")? If that
client indeed proposes ecds-sha2-nistp512, it is broken. You might perhaps be
able to work around it by adding a signature algorithm factory with that broken
name (implemented as ecdsa-sha2-nistp521, of course) to the server's list.
The second problem ("no resolved signatures") is probably because your Apache
MINA sshd server uses only an ECDSA host key but you only set RSA signature
factories.
Please take a moment to familiarize yourself with key types and which signature
algorithms are applicable for which key types.
