Hi, thanks for your help! My cvs repository is built up with cygwin(unix 
like enviroment) under win2k OS. So according to ur suggestion, I have run 
following commands in bash shell:

address@hidden ~
$ /usr/sbin/inetd start

address@hidden ~
$ telnet kaguya
Trying 172.20.54.111...
Connected to kaguya.
Escape character is '^]'.

CYGWIN_NT-5.0 1.3.19(0.71/3/2) (kaguya) (tty0)

login: cvsuser
Password:
Fanfare!!!
You are successfully logged in to this server!!!
-bash: kpsexpand: command not found

address@hidden ~
$ export CVSROOT=:pserver:address@hidden:/home/lufang/repo

address@hidden ~
$ cvs login
(Logging in to address@hidden)
CVS password:

address@hidden ~
$ cvs co CVSROOT
setuid failed: Permission denied
cvs checkout: authorization failed: server kaguya rejected access to 
/home/lufan
g/repo for user cvsuser

address@hidden ~
$ ls -lg /home/lufang/
total 16
drwxr-xr-x    3 cvsuser  None            0 Mar  1 23:55 CVSROOT
dr-xr-xr-x    4 cvsuser  None            0 Mar  1 19:42 repo
-rw-r--r--    1 cvsuser  None         3733 Feb 27 21:50 rh_opt.gdt
-rw-r--r--    1 cvsuser  None        11507 Feb 27 21:50 rh_opt.gpr
lrwxrwxrwx    1 cvsuser  None           94 Feb 14 03:21 vi -> vim.exe

as you can see , I have switched to user "cvsuser" from user "lufang", but 
it still got the same error message.So what's wrong? I really need some 
helps here.

I'll show some important files which may related to this:
