Romain Aviolat commented on GUACAMOLE-746:
------------------------------------------
I tried to use Debian Bookworm as the base-image for guacamole-server, it
packages libssh2-1.10.0-2
([https://packages.debian.org/source/bookworm/libssh2).] According to libssh2
release notes the support for ED25519 keys has been added in version 1.9.0
I tried to use a freshly generated ED25519 key to authenticate on my server but
without luck, still with the same error message:
{code:java}
guacd_1 | guacd[459]: DEBUG: Attempting private key import
(WITHOUT passphrase)guacd_1 | guacd[459]: DEBUG: Attempting
private key import (WITHOUT passphrase)guacd_1 | guacd[459]:
DEBUG: Initial import failed: (null)guacd_1 | guacd[459]: DEBUG:
Re-attempting private key import (WITH passphrase)guacd_1 |
guacd[459]: ERROR: Auth key import failed: (null)
{code}
I don't know if we're blocked
byhttps://issues.apache.org/jira/browse/GUACAMOLE-745 or not as I couldn't
generate an ED25519 in the PEM format (I assume that it's not supported by PEM).
Let me know if I can provide more info to progress on that one.
