Package: x2goclient Severity: normal Version: 4.0.4.0 This issue happens on the Mac and Linux version of X2Go CLient (not tested: Windows version). When logging into an SSH broker x2goclient --broker-url=ssh://:22/usr/bin/x2gobroker-ssh --debug and the broker's SSH daemon's sshd_config does not allow username/password authentication, I see the below message in the debug/error log... x2go-DEBUG-../src/sshmasterconnection.cpp:681> "Authentication failed." - "Access denied. Authentication that can continue: publickey" x2go-DEBUG-../src/sshmasterconnection.cpp:711> SshMasterConnection, instance SshMasterConnection(0x7f9859f1ca20) waiting for thread to finish. x2go-DEBUG-../src/sshmasterconnection.cpp:715> SshMasterConnection, instance SshMasterConnection(0x7f9859f1ca20) thread finished. x2go-DEBUG-../src/sshmasterconnection.cpp:722> SshMasterConnection, instance SshMasterConnection(0x7f9859f1ca20) finished destructor. 2015-07-03 10:23:19.277 x2goclient[573:507] modalSession has been exited prematurely - check for a reentrant call to endModalSession: x2go-DEBUG-../src/onmainwindow.cpp:5878> Setting focus. ... but on screen I see an empty message box with exclamation mark road sign (on the Mac version) but without any text specifying the error that has just occurred.
