Summary
Makes the timeout used while waiting for messages from connected Guacamole clients configurable while preserving the existing 15-second default.
The timeout can be configured through:
client_timeoutin the[server]section ofguacd.conf-T MILLISECONDSon theguacdcommand lineCLIENT_TIMEOUTwhen using the official guacd Docker imageThe configured value is applied both while waiting for the initial
selectinstruction and while handling messages from connected users. Invalid, zero, negative, and unsafe values are rejected.Motivation
GUACAMOLE-2233 documents Chrome and Edge delaying client keepalive messages beyond the hard-coded 15-second timeout when the browser is minimized or occluded. This can cause otherwise healthy sessions to be disconnected. Operators currently need to rebuild guacd to adjust the timeout.
Keeping the default unchanged avoids altering existing deployments, while exposing the timeout allows deployments affected by browser timer throttling or intermittent relays to select an appropriate grace period.
