I have Cygwin installed on Windows 7. I made default install. I would like to use ssh config file (~/.ssh/config) to set host and options for connecting.

Normal ssh command is not able to find the config while I try to connect: ssh host If I explicitly specify config file, everything is OK: ssh -F ~/.ssh/config

I cannot found any option to set ssh client, something like /etc/ssh

Maybe ssh doesn't know where is my home folder? (I have set HOME environment variable to my home folder)

You have to run ssh-host-config first. It will generate a "ssh_config" file in /etc/.

ssh command looks for its config file under home directory from /etc/passwd. So setting HOME variable will not work.

There are many ways but we can fix it by simply making a symlink as follows.

ln -s ~ /home

The other answers didn't work for me. I just created c:\cygwin64\etc\ssh_config and pasted in the following default / example file:

# This is the ssh client system-wide configuration file.  See
# ssh_config(5) for more information.  This file provides defaults for
# users, and the values can be changed in per-user configuration files
# or on the command line.

# Configuration data is parsed as follows:
#  1. command line options
#  2. user-specific file
#  3. system-wide file
# Any configuration value is only changed the first time it is set.
# Thus, host-specific definitions should be at the beginning of the
# configuration file, and defaults at the end.

# Site-wide defaults for some commonly used options.  For a comprehensive
# list of available options, their meanings and defaults, please see the
# ssh_config(5) man page.

# Host *
#   ForwardAgent no
#   ForwardX11 no
#   RhostsRSAAuthentication no
#   RSAAuthentication yes
#   PasswordAuthentication yes
#   HostbasedAuthentication no
#   GSSAPIAuthentication no
#   GSSAPIDelegateCredentials no
#   BatchMode no

Hope that helps the next person.
