Pardon the high jacking of this threat, but I may have the same problem (or, at least, it's related). I can start another thread if it is desired... I am having the same problem with ssh. So, a little history... This is a fresh Windows 11 Cygwin installation. Everything works great, except using ssh. For example, when I type, jcabrera@jicman ~ $ ssh jic@web jcabrera@jicman ~ $ I get the prompt right away. I found out that Windows 11 comes with OpenSSH installed. I uninstalled it, rebooted, and reinstalled cygwin's openssh, and the problem is still there. I don't have any antivirus, except Microsoft's Defender, but I added two folder exclussions (c:\cygwin64 and the download folder for xmission download site). The strace of ssh is pretty long: == beg strace ssh == $ strace ssh --- Process 23800 created --- Process 23800 loaded C:\Windows\System32\ntdll.dll at 00007ffe22410000 --- Process 23800 loaded
