Mettre en oeuvre un serveur CVS
CVS est un vénérable système de gestion de sources. Ce qui suit est plus une série de cas pratique qu'un tutorial à part entière

Ne pas oublier de mettre chaque utilisateur aillant acces à CVS dans le groupe CVS
Mise en place dans Xinetd
C'est une étape assez simple avec une drake 10.1, modifier le fichier /etc/xinet.d/cvs comme suit :
service cvspserver
{
disable = <u>no</u>
socket_type = stream
protocol = tcp
wait = no
user = <u>cvs</u>
server = /usr/sbin/cvspserver
<u>passenv = PATH</u>
}
<code>
<H2>Redémarer xinetd</H2>
<code type="sh">
/sbin/service xinetd restart
{
disable = <u>no</u>
socket_type = stream
protocol = tcp
wait = no
user = <u>cvs</u>
server = /usr/sbin/cvspserver
<u>passenv = PATH</u>
}
<code>
<H2>Redémarer xinetd</H2>
<code type="sh">
/sbin/service xinetd restart
Test...
Normalement c'est fini. Pour tester (USER est l'utilisateur créé plus, pas cvs:cvs) :
Importation
Pour importer un dossier en tant que module, il faut se placer dans le dossier et taper la commande suivante :
cvs import -I ! -W "*.jar -k 'b'" -m "initial" NOM_MODULE yoran release
