Dear John, sorry for the delay I answer you; I made several attempt changing ownerships of files etc... Finally this morning i uninstalled everithing following the cygwin instructions:
"Setup has no automatic uninstall facility. Just delete everything manually:  Cygwin shortcuts on the Desktop and Start Menu  The registry tree `Software\Cygnus Solutions' under `HKEY_LOCAL_MACHINE' and/or `HKEY_CURRENT_USER'.  Anything under the Cygwin root folder, `C:\cygwin' by default.  Anything created by setup in its temporary working directory. " and downloaded another setup.exe for a new installation I run ssh-host-config -y and press enter at the environment variable question .... Default is "ntsec". CYGWIN= after I started sshd with no errors message; var/log/sshd was ok(no nassages at all) ownership of ssh_host_*, var/emty, var/log/sshd were ok I set exception for port 22 in windows firewall(well I did that before installing) sshd IS in present in taskmanager ssh to linux machine works fine BUT ssh FROM linux machine to cygwin machine still doesn' t work: $ ssh [EMAIL PROTECTED] @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: POSSIBLE DNS SPOOFING DETECTED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ The RSA host key for ***************** has changed, and the key for the according IP address ****************** has a different value. This could either mean that DNS SPOOFING is happening or the IP address for the host and its host key have changed at the same time.

Add correct host key in /home/********/.ssh/known_hosts to get rid of this message. Offending key in /home/*********/.ssh/known_hosts:8 RSA host key for ************* has changed and you have requested strict checking. Host key verification failed. $ nedit .ssh/known_hosts here I canceled lines rlative to cygwin machine and tried again: $ ssh [EMAIL PROTECTED] ssh: connect to host ************ port 22: Connection timed out $ ssh [EMAIL PROTECTED] ssh: connect to host ************ port 22: Connection timed out $ Please, have you got any idea???
