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.
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
Not heard back.
