第 7 章 cvs - Concurrent Versions System

过程 7.1. 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
