when any user try to access my server this message pops up
can anyone help this poor human being ?
WARNING - SECURITY ISSUE!
The host key received by the server for the agent you are about to connect to does not match the host key reported by the agent.
This usually means there is a third party attempting to intercept the communication between you and the server.
Please notify the system administrator about this issue!
You will not be connected to the system for now.
This error can occur when the ThinLinc master and client disagree on which agent server you should be connecting to.
This normally means that the agent hostname is resolving to a different IP for the client than for the master.
How does your ThinLinc setup look? Do you have a single machine, or one master with several separate agents?
Check the value of the parameter agent_hostname in /opt/thinlinc/etc/conf.d/vsmagent.hconf on each agent, and make sure this resolves correctly for both master and client. If this doesn’t help, please feel free to send through the master and agent logfiles /var/opt/vsmagent.log and /var/log/vsmserver.log, and the relevant client log file.
