Getting CVS Modules as a Developer with CVS

Developer access will require Secure Shell (SSH1) tools. Many recent versions of Linux will come with these tools, but if you use an older distribution like Corel Linux, you'll need to download and build them yourself:

• Install zlib if you don't already have it
• Install the OpenSSL library
  • Go to www.openssl.org
  • Click on Source in the left side menu
  • Download OpenSSL 0.9.5a or later
  • Extract the archive
  • Open a console and go to the OpenSSL source directory
  • Run the following commands:

    ./config
    make
    make test
    su -c "make install"
    

• Install the OpenSSH suite
  • Go to www.openssh.org
  • In the "For Other OS's" section of the menu on the left, Click on Linux
  • This takes you to the Portable OpenSSH page
  • Scroll down to the Download section and find a mirror near you
  • Download the latest release
  • Extract the archive
  • Open a console and go to the OpenSSH source directory
  • Run the following commands:

    ./configure
    make
    su -c "make install"
    

If you don't want to enter your password every time you run a CVS command, you'll need to generate an SSH1 (RSA) key and add it to your list of public keys at sourceforge:

• Open a console, type "ssh-keygen -t rsa1" and press enter
• Just press enter when asked for a password (unless you want to enter a passphrase for every cvs command you run)
• By default, the Public Key will be saved in a file called identity.pub in the .ssh directory in your home directory
• Copy the Public Key and paste it into your list at SourceForge
• You may need to wait up to 6 hours for this key to start working
• Make 2 copies of /etc/ssh/ssh_config (one for backup, one for editing) somewhere in your home directory
• Add the server name (the part of the CVSROOT before ":/cvsroot") on a new line at the end ot ssh_config
• On the next line, type one tab followed by "Protocol 1" (don't type the quotes)
• Copy your modified ssh_config over the old one (requires root privileges) for example:

  su -c "cp ssh_config /etc/ssh/"

CVS checkout procedure:

• Get CVS if you don't already have it
• Open a console and go to the directory that will contain your CVS modules
• Type "ssh -l username server" where server is the part of your CVSROOT before ":/cvsroot" and username is your sourceforge user name
• When you see a message like: "The authenticity of host '...' can't be established. DSA key fingerprint is ... Are you sure you want to continue connecting (yes/no)?" - type "yes" and press enter
• If ssh asks for your password, enter your sourceforge password
• You will get a message like "This is a restricted Shell Account You cannot execute anything here." This is okay. The connection will close by itself
• Type "export CVS_RSH=ssh" and press enter
• Run "cvs -z3 -d:ext:NAME@CVSROOT co MODULE" where NAME is your SourceForge user name, CVSROOT is your CVSROOT, and MODULE is the name of the module you want to checkout
• Enter your SourceForge password if prompted (this will happen if you didn't create an ssh key or ssh doesn't find your private key where it expects to find it)
