What protocol are you using to connect? I ask because the SSH and Telnet protocols, in particular, actually do resolve the hostname to its IP addresses and then loop through each result, trying each one until one succeeds: https://github.com/apache/guacamole-server/blob/870cc5fc32f2806985a7868004e1324658d87f61/src/common-ssh/ssh.c#L426-L477 https://github.com/apache/guacamole-server/blob/870cc5fc32f2806985a7868004e1324658d87f61/src/protocols/telnet/telnet.c#L404-L447 VNC and RDP, on the other hand, abstract away that functionality to the underlying libraries (libvncserver and FreeRDP, respectively), so there's a bit less control that Guacamole has over how those connections behave. Kubernetes support also seems to delegate this to the underlying library (LWP). -Nick --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@guacamole.apache.org For additional commands, e-mail: user-h...@guacamole.apache.org
