I have configured SSHD using Cygwin on Windows 7. I have checked and double-checked all of the following points:
- Port forwarding is correctly configured
- Windows Firewall is configured to pass port 22
- Local login attempts (using Cygwin SSH) succeed
- Using nmap from remote machine confirms port 22 is accessible
/etc/groupare correctly populated
However, remote login attempts time out. This includes from the local network.

No messages are logged to
/var/log/sshd.log. I suspect that there is a permissions issue with a particular file somewhere, however I have checked the permissions of all my Cygwin binaries, DLLs and the particular files important to Cygwin sshd, including all of:
Others who have reported this or similar errors appear to have missed one of the points enumerated above. Can anyone point me to a possible solution?
As requested, the
netstat output, with
>netstat | find "22" TCP [::1]:24499 Hostname:ssh TIME_WAIT
Disabling IPv6 doesn't change anything. But I noticed some debug output from
sshd which might be relevant:
