====== Cygwin unattended for BackupPC ======
==== Introduction ====
This is a howto describing an unattended installation of Cygwin including both Rsyncd and SSHD. Rsyncd is there to make your backup setup from the BackupPC server more simplified. No setting up SMB shares or any business, just use one master rsyncd.conf file with all of your shares for all of your servers and you're in business. The sshd is intended to allow you to execute remote commands. This can be useful if you want to dump a database or setup a VSC to pull from instead of being denied access to open files. [[wiki:cygwin_install_backuppc_rsyncd#Related_Links|Relavent links]] can be found at the bottom of this howto.
==== Prerequisites ====
  * A central share to store all of your files - should be heavily but properly guarded
  * Administrative rights and the ability to use psexec to run commands on the remote server
==== The scripts ====
== cygwin_install.cmd ==
This is the script that does most of the heavy lifting. It's copied to and executed on the remote host. The quick rundown of what it does are as follows:
  - Copy entire install directory to a local path
  - Setup cygwin including the necessary packages for rsyncd and sshd
  - Prerequisite junk
  - Setup SSH daemon
  - Open necessary firewall ports
  - Copy rsyncd config files to /etc directory
  - Start SSH daemon
  - Create then rsyncd windows service
  - Cleanup

<file DOS cygwin_install.cmd>
mkdir C:\cygwin_install
copy /Y \\mn-ms3.gsellc.local\cygwin_install C:\cygwin_install

C:\cygwin_install\setup-x86_64.exe -q -D -s http://mirrors.xmission.com/cygwin -l C:\cygwin64 -L C:\cygwin64 -P base-cygwin,wget,git,git-svn,openssh,cygrunsrv,rsync
C:\cygwin64\bin\mkpasswd.exe -l > C:\cygwin64\etc\passwd
C:\cygwin64\bin\mkgroup.exe -l > C:\cygwin64\etc\group
C:\cygwin64\bin\bash.exe --login -c "/usr/bin/chown :Domain\ Users /var"

net start sshd
setx path "c:\cygwin64\bin;%path%"
c:\cygwin64\bin\cygrunsrv.exe --install "rsyncd" --path C:/cygwin64/bin/rsync.exe --args "--daemon --no-detach" --desc "Starts a rsync daemon for accepting incoming rsync connections" --disp "Rsync Daemon" --type auto
net start rsyncd

del /Q C:\cygwin_install
rmdir C:\cygwin_install
</file>
== doit.cmd ==
This is just a psexec launcher. Very straightforward and worthless:
<file DOS doit.cmd>
.\psexec.exe \\%1 -e -s -c cygwin_install.cmd
</file>
So when it's time to "do it" you will just `.\doit hostname`
