.SH NAME
cvssh \- quick shell for anonymous CVS servers
.SH SYNOPSIS
.B cvssh
.SH DESCRIPTION
The
.B cvssh
is intended to be used as the login shell of an anonymous CVS server
account.  It's not terribly useful in the outside world, because it
requires a patched version of CVS which I haven't released.
.SH ANONYMOUS CVS
Suppose you want to set up a CVS repository in
.B /home/cvs/cvs
with the anonymous user
.BR anoncvs .
The following steps will get this done:
.IP "   1."
Make the directory
.B /home/cvs
owned by
.B root
with mode 755, and execute
.sp 1
.RS 10
.nf
.ft B
cvs -d /home/cvs/cvs init
.ft R
.fi
.RE
.IP ""
to create the repository.
.IP "   2."
Add a user
.B anoncvs
with a disabled password, shell set to
.B chrootsh
and home directory set to
.BR /home/cvs/./cvs .
.IP "   3."
As the super-user, run the following commands:
.PP
.RS 10
.nf
.ft B
# cd /home/cvs
# mkdir -m 711 bin dev etc lib
# mkdir -m 1777 tmp
.ft R
.fi
.RE
.IP ""
You may need some other directories as well.  For example, Digital Unix
users will want to make
.B shlib
and
.B sbin
for the shared library system to work properly.
.IP "   4."
Copy the programs
.BR cvs ,
.B gzip
and
.B sh
into
.BR /home/cvs/bin .
If your version of
.B /bin/sh
is really the Free Software Foundation's
.B bash
in disguise (e.g., you're a Linux user) then you're probably better off
installing something lighter-weight like the FreeBSD shell (available in
a guise called
.B ash
with Debian GNU/Linux).  It's smaller and doesn't need as many shared
libraries.
.IP ""
Also copy in the
.B cvssh
binary.
.IP "   5."
Copy in the shared libraries needed.  If you have an
.B ldd
binary handy, run
.sp 1
.RS 10
.nf
.ft B
# ldd bin/*
.ft R
.fi
.RE
.IP ""
and copy in what it tells you to.  Otherwise you'll have to find things
out the hard way by looking at error messages.  Do any other
configuration your shared library system needs or desires here.  For
example, Linux users should run
.sp 1
.RS 10
.nf
.ft B
# ldconfig -r/home/cvs
.ft R
.fi
.RE
.IP ""
to make a cache file for the shared loader.
.IP "   6."
Make any devices needed in the
.B /dev
directory.  For Linux, that probably involves
.sp 1
.RS 10
.nf
.ft B
# mknod -m666 dev/null c 1 3
# mknod -m666 dev/zero c 1 5
.ft R
.fi
.RE
.IP ""
Other operating systems will, of course, be different.
.IP "   7."
Edit the password and group files the
.B etc
directory.  My versions are extremely minimal.  The important thing is
that the
.B anoncvs
user should have an entry like the one in the main password database but
with home directory
.B /cvs
and shell
.BR /bin/cvssh .
The
.B passwd
file should contain no passwords or other useful information.  Only put
other users in the files if you really feel like it.
.IP "   8."
Finishing touches.  Run the command
.sp 1
.RS 10
.nf
.ft B
# touch cvs/.hushlogin
.ft R
.fi
.RE
.IP ""
to make sure that logging in doesn't spew junk everywhere.
Also, if you're planning on using SSH, do
.sp 1
.RS 10
.nf
.ft B
# mkdir cvs/.ssh
# touch cvs/.ssh/rc
.ft R
.fi
.RE
.IP ""
to make SSH stop trying to play silly games with
.BR xauth .
.IP "   9."
Relax.  You're done.
.SH BUGS
None planned.
.SH "SEE ALSO"
.BR chrootsh (8),
.BR cvs (1).
