Please check http://cygwin.com/ for information about current Cygwin releases. -Build instructions are at the end of the file. - -=========================================================================== -Important change since 3.7.1p2-2: - -The ssh-host-config file doesn't create the /etc/ssh_config and -/etc/sshd_config files from builtin here-scripts anymore, but it uses -skeleton files installed in /etc/defaults/etc. - -Also it now tries hard to create appropriate permissions on files. -Same applies for ssh-user-config. - -After creating the sshd service with ssh-host-config, it's advisable to -call ssh-user-config for all affected users, also already exising user -configurations. In the latter case, file and directory permissions are -checked and changed, if requireed to match the host configuration. - -Important note for Windows 2003 Server users: ---------------------------------------------- - -2003 Server has a funny new feature.

According to that document the -privsep feature requires a non-privileged account called 'sshd'. - -The new ssh-host-config file which is part of this version asks -to create 'sshd' as local user if you want to use privilege -separation. If you confirm, it creates that NT user and adds -the necessary entry to /etc/passwd. - -On 9x/Me systems the script just sets UsePrivilegeSeparation to "no" -since that feature doesn't make any sense on a system which doesn't -differ between privileged and unprivileged users. - -The new ssh-host-config script also adds the /var/empty directory -needed by privilege separation. When creating the /var/empty directory -by yourself, please note that in contrast to the README.privsep document -the owner sshould not be "root" but the user which is running sshd. So, -in the standard configuration this is SYSTEM. The ssh-host-config script -chowns /var/empty accordingly. -=========================================================================== - -=========================================================================== -Important change since 3.0.1p1-2: - -This version introduces the ability to register sshd as service on -Windows 9x/Me systems. This is done only when the options -D and/or --d are not given. -=========================================================================== - -=========================================================================== -Important change since 2.9p2: - -Since Cygwin is able to switch user context without password beginning -with version 1.3.2, OpenSSH now allows to do so when it's running under -a version >= 1.3.2. Keep in mind that `ntsec' has to be activated to -allow that feature. -=========================================================================== - -=========================================================================== -Important change since 2.3.0p1: - -When using `ntea' or `ntsec' you now have to care for the ownership -and permission bits of your host key files and your private key files. -The host key files have to be owned by the NT account which starts -sshd. The user key files have to be owned by the user. The permission -bits of the private key files (host and user) have to be at least -rw------- (0600)! - -Note that this is forced under `ntsec' only if the files are on a NTFS -filesystem (which is recommended) due to the lack of any basic security -features of the FAT/FAT32 filesystems. -=========================================================================== +================== +Host configuration +================== If you are installing OpenSSH the first time, you can generate global config -files and server keys by running +files and server keys, as well as installing sshd as a service, by running /usr/bin/ssh-host-config Note that this binary archive doesn't contain default config files in /etc. That files are only created if ssh-host-config is started. -If you are updating your installation you may run the above ssh-host-config -as well to move your configuration files to the new location and to -erase the files at the old location. - To support testing and unattended installation ssh-host-config got some options: @@ -123,16 +26,25 @@ Options: --no -n Answer all questions with "no" automatically. --cygwin -c Use "options" as value for CYGWIN environment var. --port -p sshd listens on port n. - --pwd -w Use "pwd" as password for user 'sshd_server'. + --user -u privileged user for service, default 'cyg_server'. + --pwd -w Use "pwd" as password for privileged user. + --privileged On Windows XP, require privileged user + instead of LocalSystem for sshd service. -Additionally ssh-host-config now asks if it should install sshd as a -service when running under NT/W2K.
