Issue:
ssh command run from Jenkins shell will take “/” as home directory and hence it tries to look for all the files in that directory like “/.ssh/known_hosts” & /.ssh/id_rsa. It typically happens in Windows cygwin shell
Environment:
Jenkins
Windows Slave
Cygwin
ssh
Error:
debug3: check_host_in_hostfile: filename /.ssh/known_hosts
debug3: check_host_in_hostfile: filename /etc/ssh_known_hosts

Build was aborted
Fix:
1) Run Jenkins service as “Administrator”. By default it will be running as "Local user"
Start -> run -> services.msc -> Jenkins Slave -> Right click -> Properties -> Log on -> This account ->
Start -> run -> services.msc -> Jenkins Slave -> Right click -> Properties -> Log on -> This account ->
Give Administrator & password.
Then in jenkins -> manage nodes -> Select your machine -> Disconnect -> Then reconnect.
Make sure the slave is launched as "Windows service"
The above step should fix the issue.
Note: Step 2 is optional.
2) Run Cygwin-sshd as “Administrator. By default it will be running as “cyg_server”
Jenkins upgrade > 1.444
If you upgrade jenkins to latest versions, again ssh commands through windows will hang for the same reason mentioned above.
The fix is not to run Jenkins service as 'Local user'. Now you can configure it through jenkins node configuration page.
Login to jenkins -> Manage Jenkins -> Manage Nodes -> Click on your node -> configure -> Run service as -> select 'Log on using a different account' ->
For ex:
User name: .\Administrator
pasword: ********
Note: .\ in user name is must , otherwise it fails with
ERROR: Failed to create a service: Status Invalid Service Account
