As suspected it was a problem on my PC, but I would like to inform about the cause in case other people have a similar problem. The root cause was that the Citrix Workspace app installed on my PC had application protection enabled. This interfered with some of the Cygwin apps (mainly ssh and apps using ssh, but also others) so I had to reinstall this app without application protection enabled.

Good point and it needed to be tested, so that is out of the picture. Repeating what I hinted to above, maybe running the program under gdb you are specifying the whole path to the program, which is not the same as letting the shell find it. Try: `which ssh` to see which one is used. Another test is to use ldd or cygcheck to take a look at the libraries loaded... if they include anti-virus or other strange libraries, then that is interfering. Also using strace could (probably will) show where everything stops.

I have tested with IP addresses so that is not an issue. I have also checked that I am using the Cygwin application by providing the whole path. I have also tried strace, but it bails out with an exception (c005) and then segmentation fault. Attached you will find an output from: cygcheck -s -v -r > cygcheck.out ldd /usr/bin/ssh-keygen.exe > ldd_ssh-keygen.out strace /usr/bin/ssh-keygen.exe > strace_ssh-keygen.out Hopefully someone can make something out of this.

To me it sounds like a path conflict, missing, wrong or duplicate configuration, or keys in this case. Are you, or were you using one of these applications also natively on Windows? If it's a new system, maybe you don't know something was preinstalled. On the other hand, did you even install Cygwin's own packages, and are you sure you're starting those? (Try `which `) Are you or is something modifying your environment? Where are your ssh keys stored? You probably need to make those apps aware of where they are.

I have a problem with some applications in Cygwin
Hello I have been using for many years and have not really had any major problems, but now I have run into a problem with some of the applications in Cygwin that I have been struggling with for some time without being able to solve it. Hopefully someone in this list can point me in the right direction to fix the problem. I have a new Windows 10 PC with a fresh Cygwin installation, but struggles with some of the applications that I have installed. When I try to use applications like ssh, ssh-keygen, git, snmpwalk, snmpnext etc. they all just hangs and I am not able to stop them through CTRL-C. I need to use Task Manager to kill the application (kill -9 does not work either). But if I run the application from gdb (like 'gdb ssh-keygen' and the 'run') they seem to work. Most applications seems to work as expected, but not the ones I have listed (and maybe some more applications as well). I think that this might be due to something in my PC, but are not able to pinpoint it. At one point I thought that this was due to the virus control in the PC (Trend), but now I have uninstalled this and just uses Windows defender.
