When logged into a ThinLinc session which is tunneling RDP from a WTS, everything works fine until the Windows machine disappears unexpectedly (such as through a crash or a power failure), at which point the ThinLinc desktop just stops responding, but is still present and shows the last screen update before the crash. A quick look at the server shows that rdesktop is still running.
Many things have changed since this report, I have verified that the new reconnect behavior works and then terminates.
Related problems fixed in vendor drop 28387.
Works, tested against 2003 R2 but turning it off. Noticed that rdesktop was stuck in sendto() for several minutes, but then this was printed in the console: ERROR: send: Ingen väg till värd ERROR: Connection closed Disconnected due to network error, retrying to reconnect for 70 minutes. Failed to negotiate protocol, retrying with plain RDP. WARNING: Automatic reconnect using cookie, failed. Also tested disconnected the VMware interface of the 2003 R2 machine. It took about 10 minutes until rdesktop detected that the machine was down. Good enough for now.
