过程 4.1. 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


environment variable

CVSROOT=:pserver:username@ip:/home/cvsroot

vim .bashrc

export CVS_RSH=ssh
export CVSROOT=:pserver:neo@localhost:/home/cvsroot


test

$ cvs login
Logging in to :pserver:neo@localhost:2401/home/cvsroot
CVS password:
neo@netkiller:/tmp/test$ cvs co test
cvs checkout: Updating test
U test/.project
U test/NewFile.xml
U test/newfile.php
neo@netkiller:/tmp/test$

environment variable

neo@netkiller:~/workspace/cvs$ export CVSROOT=:pserver:neo@localhost:/home/cvsroot


ssh

export CVS_RSH=ssh
export CVSROOT=:ext:$USER@localhost:/home/cvsroot
