CVS Configuration

1) First we need to create enviornment variable called CVSROOT and point it to the root of the repository

export CVSROOT=/home/cvsroo t

It can have othernames than cvsroot

2) Now we need to initialise the repository with the following command. Be root to do this.

cvc init

3) Next we have to setup files, directories and then define a module.

Suppose I have a directory called "staff/resume" with some files that should be added to CVS.
To import these files go to staff/resume directory and issue this command

cvs import -m "Import Source" staff/resume thestaff start
cvs checkout CVSROOT/modules

Now Alter the modules file in root directory (not repository) and add this

resume staff/resume

Now save the file and issue the command

cvs commit -m "Added resume module." modules

Now this creates our needed file in CVSROOT. Now we can delete the original
staff/resume directory.

One way is to rm -rf staff. But a better and safer way is

cvs release -d staff

4) Now we should give proper unix group and user permission for modules
directory as this determines who can commit changes. It means that modules
directory should be owned by group who has permission to commit change.
Also group must have write permission if they have permission to update CVS.

5) To make the changes you have made locally into the repository use command

cvs commit staff

or to update

cvs update staff

Normally its good to update the cvs and then give command commit.

6) To create login authentication for cvs do the following.
a) Create a /etc/xinetd.d/cvspse rver file if it does not exist, and add the

service cvspserver
port = 2401
socket_type = stream
protocol = tcp
wait = no
user = root
passenv = PATH
server = /usr/bin/cvs
server_args = -f --allow-root=/usr/cv sroot pserver

Then restart xinetd with /usr/xinetd restart

b) Now create password file in $CVSROOT/CVSROOT/pas swd with following content

ullas:$1$75g0K7Vm$UL M55Jj/b6QvVB8RxAlk5/
vikas:@#$$$%76776655 66@45667777665555667 :ullas
suvas:233$$%76776655 66@45667777665555667 :ullas

Here password is unix crypt.
Here ullas will have permission if he supplies password. Vikas user can login
with password even if he does not have an account in server and he will run as
ullas in this case. Simalar is the case with Suvas.

c) Now you can login with following command

cvs -d :pserver:anonymous@l ocalhost:/home/cvsro ot co staff
cvs -d :pserver:ullas:sallu t123@localhost:/home /cvsroot co staff

d) You can make this as your CVSROOT enviornment variable in .bash_profile
like the comman below.

CVSROOT=:pserver:ull as:sallut123@localho st:/home/cvsroot co staff

e) To create readonly access to CVS create a file $CVSROOT/CVSROOT/rea ders
with following contents.


Now above three persons becomes read only members of cvs.
