1. Linux/Unix

1.1 SSH

• If your distribution doesn't include a ssh implementation visit openssh.org or www.ssh.com to get and install SSH.
• test ssh: ssh -l username cpgnuke.com
• create the ssh public and private identity keys

1.2 CVS

• If your distribution doesn't include CVS visit ximbiot.com/cvs/cvshome/ to get and install CVS

  wget https://ccvs.cvshome.org/files/documents/19/863/cvs-1.11.20.tar.gz
  tar zxf cvs-1.11.20.tar.gz
  cd cvs-1.11.20
  ./configure --prefix=/usr/local
  make && make install

• set CVS_RSH=ssh. If you use bash you can add the following lines to your .bash_profile (don't forget to re-login!)

  CVS_RSH=ssh
  export CVS_RSH

1.3 hint(s)

• you can alias cvs='cvs -z9' to use compression without specifying -z9 every time. Add the following line to your .bashrc (don't forget to re-login!)

  alias cvs='cvs -z9'

• if you still need to fill in your password then the key isn't used and you should run the following commands

  ssh-agent bash
  ssh-add dragonflycvskey

2.1 Create a home directory

• create a new directory as your home directory (unix-style commands will store here their configuration files), for example: c:\home
• add set HOME=c:\home to your autoexec.bat (don't forget to restart windows!)

2.2 SSH

• Get and install SSH from openssh.org or www.ssh.com, or you can get an older version that is know to work from here
• test ssh: ssh -l username cpgnuke.com
• create the ssh public and private identity keys

2.3 CVS

• Get and install CVS from march-hare.com/cvspro/ (if you plan to use WinCVS gui frontend you can use CVS client that is included in WinCVS distribution)

• add set CVS_RSH=ssh to your autoexec.bat (don't forget to restart windows!)

LinCVS is a free GUI frontend for CVS. You can download it from lincvs.org.

TortoiseCVS is a free Windows Explorer integration for CVS. You can download it from tortoisecvs.org.

WinCVS is a free GUI frontend for CVS. You can download it from wincvs.org (it include a working version of CVS).

5.1 WinCVS configuration

• General/CVSROOT= :ext:username@cpgnuke.com:/cvs
• General/Authentification: SSH server
• optional: if you created ssh identity keys set RSA identity to your %home%/.ssh/identity file
• optional: Globals/TCPIP compression to 9 (recommended)
• Ports/Alternate rsh name: ssh
• WinCVS/Home: your home directory

5.2 hint(s)

• ! important: if you don't use ssh identity keys you will need to type your password in the black console window that appear when you activate a CVS command

Creating those keys allow you to access Dragonfly server without typing your password every time.

6.1 Creating SSH identity keys

1. ssh-keygen -trsa -fdragonflycvskey -C username@cpgnuke.com
   (from your local computer, you should now have two files .dragonflycvskey and dragonflycvskey.pub in your .ssh directory)
2. Check if the remote machine has a .ssh directory

   ssh username@cpgnuke.com
   ls -la

   if not, then create it:

   mkdir .ssh
   chmod 0700 .ssh

3. copy public identity file to dragonfly server: cat dragonflycvskey.pub | ssh username@cpgnuke.com "umask 077; cat >> .ssh/authorized_keys" (from your local computer)

Now you can try to login with ssh -l username cpgnuke.com and you shouldn't be asked for a password. For more information regarding dragonfly access and ssh identity keys read SSH Keys and CVS/Shell Accounts at Sourceforge.

6.2 Using the same identity keys under Linux and Windows

Just copy dragonflycvskey and dragonflycvskey.pub in .ssh subdirectory of your home directory on your local machine (from Linux partition to Windows or from Windows partition to Linux).

! Important: if you have copied identity keys from Windows partition to Linux don't forget to set access mode to 600, otherwise they will not work. (chmod 600 .ssh/dragonflycvskey*)
