13.1. installation

过程 13.1. install cvs

  1. install

    $ sudo apt-get install xinetd
    $ sudo apt-get install cvs
    			

    show the cvs version

    $ cvs -v
    
    Concurrent Versions System (CVS) 1.12.13 (client/server)
    			
  2. create cvs group and cvsroot user

    $ sudo groupadd cvs
    $ sudo adduser cvsroot --ingroup cvs
    			

    change user become cvsroot

    $ su - cvsroot
    			
  3. initialization 'CVSROOT'

    $ cvs -d /home/cvsroot init
    			

    if you have successed, you can see CVSROOT directory in the '/home/cvsroot'

    $ ls /home/cvsroot/
    CVSROOT
    			
  4. authentication

    default SystemAuth=yes, you can use system user to login cvs.

    but usually, we don't used system user because it isn't security.

    SystemAuth = no

    edit '/home/cvsroot/CVSROOT/config' make sure SystemAuth = no

    $ vim /home/cvsroot/CVSROOT/config
    SystemAuth = no
    			

    create passwd file

    the format is user:password:cvsroot

    you need to using htpasswd command, if you don't have, please install it as the following

    $ sudo apt-get install apache2-utils
    			

    or

    $ perl -e 'print("userPassword: ".crypt("secret","salt")."\n");'
    			

    or

    $ cat passwd
    #!/usr/bin/perl
    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";
    
    $ ./passwd "mypasswd"
    atfodI2Y/dcdc
    			

    let's using htpasswd to create a passwd

    $ htpasswd -n neo
    New password:
    Re-type new password:
    neo:yA50LI1BkXysY
    			

    copy 'neo:yA50LI1BkXysY' and add ':cvsroot' to the end

    $ vim /home/cvsroot/CVSROOT/passwd
    neo:yA50LI1BkXysY:cvsroot
    nchen:GXaAkSKaQ/Hpk:cvsroot
    			
  5. Go into directory '/etc/xinetd.d/', and then create a cvspserver file as the following.

    $ sudo vim /etc/xinetd.d/cvspserver
    
    service cvspserver
    {
       disable = no
       flags = REUSE
       socket_type = stream
       wait = no
       user = cvsroot
       server = /usr/bin/cvs
       server_args = -f --allow-root=/home/cvsroot pserver
       log_on_failure += USERID
    }
    			
  6. check cvspserver in the '/etc/services'

    $ grep cvspserver /etc/services
    cvspserver      2401/tcp                        # CVS client/server operations
    cvspserver      2401/udp
    			
  7. restart xinetd

    $ /etc/init.d/xinetd
    Usage: /etc/init.d/xinetd {start|stop|reload|force-reload|restart}
    			
  8. port

    $ nmap localhost -p cvspserver
    
    Starting Nmap 4.53 ( http://insecure.org ) at 2008-11-14 16:21 HKT
    Interesting ports on localhost (127.0.0.1):
    PORT     STATE SERVICE
    2401/tcp open  cvspserver
    
    Nmap done: 1 IP address (1 host up) scanned in 0.080 seconds
    			
  9. firewall

    $ sudo ufw allow cvspserver
