I am a programmer from the US[Michigan].
I need your help for setting up cvs repository server.I am getting an error called "BROKEN PIPE ERROR SIGNAL" when i try to login into the repository. I am using pserver and port 2401 as suggested in many articles..PLEASE HELP ME REGARDING THIS.It would be of great help if you can mail me the details of how to set up the server. I HAVE PASTED THE DETAILS I HAVE USED TO SET UP AND ALSO POINTED WHERE I AM STRUCK.Please help me out and also treat this as urgent.

Login as root on repository machine

Create a user (& group) called: cvs

Create repository:

cvs -d /usr/local/cvsroot init
(Repeat this process if you want to create multiple repositories e.g., /usr/local/cvsroot2, /usr/local/cvspublic etc). Each repository can have different sets of authorized users.

Change owner and group of repository and all files to cvs:

chown -R cvs.cvs /usr/local/cvsroot
Create tcp service by editing /etc/services - add line (NOTE: May already be present):

cvspserver 2401/tcp #CVS PServer
Create inetd entry for service by editing /etc/inetd.conf - add following lines:

# CVS PServer
cvspserver stream tcp nowait cvs /usr/bin/cvs cvs --allow-root=/usr/local/cvsroot pserver NOTE: The above line "cvspserver stream ..." must appear on a single line. If you created multiple repositories in step 3, add an additional --allow-root=[repository path] argument for each repository.

Restart inetd. NOTE: Because you will be restarting inetd from root's session, it will inherit the environment, most notably HOME=/root. This causes the following error when you try to check anything out of the repository:

cvs server: cannot open /root/.cvsignore: Permission denied
cvs [server aborted]: can't chdir(/root): Permission denied
To remedy this, use one of two methods.
1) The first method is to restart the server (the problem does not occur when inetd is started during system startup. 2) The second method is a manual restart while logged in as root. For this to work you need to restart inetd without the HOME pointing to root's home directory. Start a terminal session and enter the following:

unset HOME
/etc/rc.d/init.d/inet restart
Now login as the user cvs. We will now setup the password file for cvs users.

You will need a utility to create encrypted passwords. You can use the below perl script for that purpose:


srand (time());
my $randletter = "(int (rand (26)) + (int (rand (1) + .5) % 2 ? 65 : 97))";
my $salt = sprintf ("%c%c", eval $randletter, eval $randletter);
my $plaintext = shift;
my $crypttext = crypt ($plaintext, $salt);

print "${crypttext}\n";
Create a text file in /usr/local/cvsroot/CVSROOT called passwd and enter the users as shown below (format is: userid:encrypted-password:cvs ):

NOTE: Use the utilty from above to generate the encrypted passwords for the above entries. The passwords for the users should NOT be the same as their unix password (if they have a unix account). The cvs users you enter above do NOT need a unix account.

Set restrictive permissions on the file:

chmod 400 /usr/local/cvsroot/CVSROOT/passwd
(optional) Repeat step 10 and 11 for each additional repository you created in step 3.

Repository Testing
Set the default repository in the environment (will save entering it on every cvs command):

export CVSROOT=:pserver:address@hidden:/usr/local/cvsroot (substitute real values for username1, your_server_name and repository path if needed)

Test the basic login:

cvs login
Enter the username1's password. There should not be any error messages.


Create a tiny test project:

mkdir testproj
echo "//Main Class">testproj/
Import the project to the repository.

cd testproj
cvs import -m "My initial project message" testproj mycompany start Check to make sure the project was created in the repository. You should see the file in /usr/local/cvsroot/testproj

Remove the test project from the repository:

rm --R /usr/local/cvsroot/testproj
