23.1 Legacy Series / [SOLVED] SSH handshake error with Apache Guacamole
« on: July 16, 2023, 10:18:35 pm »
Hello !
SSH connection between Apache Guacamole and OpnSense fails with this message : "The remote desktop server encountered an error and has closed the connection. Please try again or contact your system administrator.".
In Guacamole, the error displayed in "/var/log/syslog" is :
In OpnSense, the error in "var/log/audit/audit_20230716.log" is :
I use Guacamole v1.5.2, OpenSSH/OpenSSL versions are OpenSSH_8.4p1 Debian-5+deb11u1, OpenSSL 1.1.1n 15 Mar 2022.
And I use OpnSense v23.1.11-amd64, OpenSSH/OpenSSL versions are OpenSSH_9.3p1, OpenSSL 1.1.1u 30 May 2023
Is the error due to incompatibility between those versions ?
