Xpra: Ticket #2245: xpra is not parsing attach command line since 2.5

Starting with 2.5 and continuing in the current 3.0 release xpra doesn't appear to be parsing command-line arguments for attaching on Windows clients. This issue appeared to happen in all tested cygwin-based terminal emulators like MobaXTerm or Gitbash. For example when something like xpra attach ssh:user@host:port is run in a cygwin-based terminal emulator the following error is produced in xpra 2.5+:

xpra initialization error: invalid mode 'attach ssh:user@host:port'.

The GUI xpra client works as does command-line client in the windows command interpreter CMD.exe. The bug did not manifest before xpra-2.5.

Thank you,

Both mobaxterm and git bash work for me.

Please see wiki/ReportingBugs and provide more specific steps for reproducing the problem you are seeing. ie: the exact steps, full version details, exact command lines, full commands output, etc

Please also try the beta builds post r22261 which contain a workaround for ssh connections when running from cygwin and other terminals (we avoid using stdin for prompts).
