This is a quick howto to setup the latest CVS server on the latest Arch Linux machine. Best of luck.

Installation

Update or install to the latest version of cvs and xinetd (as root):

# pacman -S cvs xinetd


Create the cvs group - members of this group will have write access to the repository (as root):

# groupadd cvs


Create the cvs user in the cvs group (-md makes the home directory) (as root):

# useradd -md /home/cvsroot -g cvs -p Insecure0 cvs

Initialization

Initialize your CVS repository (as cvs):

cvs% cvs -d /home/cvsroot init


The permissions on the directory (not the files inside, however) should be 2775 (drwxrwxr-x), but if not, run (as cvs):

cvs% chmod 2775 /home/cvsroot


Add any users that you want to have local access to the repository to the group cvs by using the following two steps. The 'adduser' script is very handy.


You can add pre-existing users to the cvs group with the command (as root):

# gpasswd -a username cvs


Make a file in /etc/xinetd.d/ called cvspserver with these contents (as root):

service cvspserver
{
        port            = 2401
        socket_type     = stream
        protocol        = tcp
        wait            = no
        user            = root
        passenv         = /home/cvsroot
        server          = /usr/bin/cvs
        server_args     = -f --allow-root=/home/cvsroot pserver
}


Edit /etc/services and add this line containing the information for cvspserver service if does not exist (as root):

cvspserver 2401/tcp     #CVS PServer

Now restart xinetd (as root):

/etc/rc.d/xinetd restart

Configuration

Become cvs ("su cvs") and create a 'passwd' file in ~/CVSROOT. To add entries in the file you can use htpasswd command (present in the apache package) like that:

htpasswd -b filename username password

then edit che file and add che group, should look like this:

# Format is username:password:group

anonymous::
luser:HopefullySecure0:cvs
other:Insecure0:cvs


Now create a 'writers' file in ~/CVSROOT, which grants write privileges to the users you created in 'passwd':

luser
other


Now create a 'readers' file in ~/CVSROOT, which grants read privileges to the users you created in 'passwd':

anonymous

NOTE: if a user is present in the readers file can't have write access too!!

Use

You can test out the server using the following commands:

export CVSROOT=:pserver:my_user_name@127.0.0.1:/home/cvsroot
cvs login
mkdir ~/sandbox
mkdir ~/sandbox/myproject
cd ~/sandbox/myproject
echo "this is a sample file" > myfile
cvs import -m "description of myproject" myproject v1 r1
cd ..
rm -R myproject
cvs checkout myproject
cd myproject
echo "some changes to the file" >> myfile
cvs commit -m "Explain changes here" myfile
