X
X So, you want to run an anoncvs server.
X
X A summary of the steps you'll need to do is:
X
X1) Find enough disk space to hold the anoncvs tree, and mount it in an
X appropriate place.
X
X2) Compile and install anoncvssh, the shell used for the anoncvs user.
X Install the cvsync client using 'pkg_add cvsync' command.
X ( If you aren't using OpenBSD you'll probably need to compile a cvsync
X client as well. The easier path is to use OpenBSD ;).
X
X3) Add the anoncvs user to the password file, with no password, and
X anoncvssh as it's shell. Decide on a user that will run cvsync to maintain
X the archive (this is a different user, NOT the anoncvs user).
X
X4) Make a home directory for the anoncvs user. The anoncvs user's
X home directory is a chroot jail in which the anoncvssh processes
X run when servicing anoncvs requests. The jail must contain the
X cvs binary as well as whatever shared libraries and support files
X are needed to run them unless you compile and link everything
X statically. This example shows what is needed for OpenBSD. If you
X use another platform you'll need to be familiar with what needs
X to go in a chroot jail for your platform.
X
X5) Get permission to use cvsync to obtain the cvs tree from a server.
X
X6) Set up cvsync to retrieve the cvs tree from an appropriate place.
X
X7) Run cvsync to retrieve the distribution from the server.
X
X8) Once you get the distribution in, set up a cron job to run cvsync
X periodically to keep your server up to date.
X
X9) Enabling OpenCVS anoncvs.
X
X**********************************************************************
XSTEP 1) find enough disk space.
X You need roughly 2GB.
X Mount it on /open, make sure it doesn't have nosuid and nodev flags.
X If you are not able to mount it as /open, substitute it's location
X throughout the rest of this description.
X
X**********************************************************************
XSTEP 2) compile the anoncvssh binary.
X In the Makefile, change the variable CVSROOT.
X Install the binary setuid-root in /open/anoncvssh.
X
X**********************************************************************
XSTEP 3) Create the anoncvs account and decide who will run "cvsync"
X to maintain the archive. The anoncvs account should *NOT* be the one
X running cvsync to maintain the archive.
X
Xcreate an account similar to:
X
X anoncvs::32766:32766::0:0:Anonymous CVS User:/open/anoncvs:/open/anoncvssh
X
XYes, that is right - the account has no password. Be sure that the
Xuid and gid are unique for your system, if the ones above aren't,
Xpick different values.
X
XDecide who will run cvsync to maintain the archive. Call that user
X$CVSYNCUSER. Oh, and in case it hasn't been previously mentioned,
X$CVSYNCUSER should *NOT* be the anoncvs user :).
X
XSet "PermitEmptyPasswords yes" option in /etc/ssh/sshd_config and
Xrestart your sshd daemon.
X
X**********************************************************************
XSTEP 4) Build the anoncvs user's home directory chroot jail. This
X example assumes that you're using OpenBSD. If you're not you
X may need different files in the chroot.
X
Xmkdir /open/anoncvs
Xmkdir /open/anoncvs/cvs
Xchown -R $CVSYNCUSER /open/anoncvs/cvs /open/anoncvs
X
XStart filling the account up with nice stuff. You are building a chroot
Xjail for anoncvs in /open/anoncvs.
X
X cd /open/anoncvs
X touch .hushlogin
X touch .profile
X
XPut a message like the following in .plan:
X To use anonymous CVS install the latest version of CVS on your local
X machine.
X Then set your CVSROOT environment variable to the following value:
X anoncvs@anoncvs.openbsd.org:/cvs
X
X mkdir bin dev tmp usr var etc
X cp /bin/{cat,pwd,rm,sh} bin/
X
XUsing mknod, make a dev/null that has the same major/minor numbers as
X your /dev/null, and make it mode 666.
X
XSome shared library systems require a dev/zero created in the same way.
X
XFill etc space for the account
X cp /etc/{group,hosts,passwd,protocols} etc/
X cp /etc/{pwd.db,resolv.conf,services,ttys} etc/
X modify these files to suit your idea of system security
X
Xanoncvssh (by setting the environment variable CVSREADONLYFS) uses
Xa tiny extension provided in the openbsd cvs server code which
Xpermits the use of read-only cvs repositories, therefore you MUST
Xcompile the openbsd version of cvs. Luckily this is not a problem
Xon a non-openbsd machine, since the cvs sources are imported verbatim
Xinto the openbsd tree. They are in gnu/usr.bin/cvs. The sources
Xare integrated in such way that Makefile.bsd-wrapper knows how to build
Xthe sources on an OpenBSD machine, using obj directories.
X
XCreate tmp space for the account
X # (cd var && ln -s ../tmp tmp)
X # chmod a+rwx tmp
X
X # mkdir usr/{bin,lib}
X # cp /usr/bin/cvs usr/bin/
X
XIf your system has ld.so in /usr/libexec,
X # mkdir usr/libexec
X # cp /usr/libexec/ld.so usr/libexec/
X
XIf using shared libraries, use ldd to find out which shared libs you need:
X # ldd /usr/bin/cvs
X /usr/bin/cvs:
X Start End Type Open Ref GrpRef Name
X 1c000000 3c01f000 exe 1 0 0 /usr/bin/cvs
X 0f802000 2f80a000 rlib 0 1 0 /usr/lib/libz.so.4.1
X 020f3000 220f8000 rlib 0 1 0 /usr/lib/libgssapi.so.5.0
X 0530c000 2531c000 rlib 0 1 0 /usr/lib/libkrb5.so.17.0
X 03801000 23841000 rlib 0 1 0 /usr/lib/libcrypto.so.18.0
X 0a8fb000 2a900000 rlib 0 1 0 /usr/lib/libdes.so.9.0
X 094d2000 2950b000 rlib 0 1 0 /usr/lib/libc.so.51.0
X 094ca000 094ca000 rtld 0 1 0 /usr/libexec/ld.so
X
X and then copy the required libraries to usr/lib/
X
XAs a final pass, make sure that all the files you have just created are
Xnot world writable (except dev/null).
X
XFor :pserver: support (optional)
X - Create an entry in /etc/services
X cvspserver 2401/tcp # CVS client/server operations
X - Create an entry in /etc/inetd.conf
X cvspserver stream tcp nowait anoncvs /open/anoncvssh anoncvssh pserver
X - Create a file /open/anoncvs/cvs/CVSROOT/passwd with the following entry
X anoncvs:AHDysQkJIubEc
X which would be a password of "anoncvs" (as per anoncvs.html)
X - Create a file /open/anoncvs/cvs/CVSROOT/readers with a single entry:
X anoncvs
X which tells cvs that user "anoncvs" is allowed readonly access.
X - Create a zero-length file /open/anoncvs/cvs/CVSROOT/writers since you don't
X want anyone to be able to write to the mirror.
X % cp /dev/null /open/anoncvs/cvs/CVSROOT/writers
X
XSee the example layout below for full details.
X
X**********************************************************************
XSTEP 5): Get cvsync permission.
Xsend mail to sup@openbsd.org
X1) to have cvsync permissions granted on an appropriate machine for you
X to cvsync from. We will need to know your host's real hostname and
X IP address.
X2) to have an anoncvsN.COUNTRY.openbsd.org alias created.
X3) to have your site mentioned in the http://www.openbsd.org/anoncvs.html page.
X
X**********************************************************************
XSTEP 6): Configure cvsync.
X
XYou have to install cvsync package.
X
XThe file /etc/cvsync.conf contains the configuration of cvsync. It will
Xnormally contain:
X
Xconfig {
X base-prefix /open/anoncvs/
X hostname anoncvs.ca.openbsd.org
X collection {
X name openbsd-cvsroot release rcs
X prefix cvs
X }
X collection {
X name openbsd-src release rcs
X prefix cvs
X }
X collection {
X name openbsd-ports release rcs
X prefix cvs
X }
X collection {
X name openbsd-www release rcs
X prefix cvs
X }
X collection {
X name openbsd-xenocara release rcs
X prefix cvs
X }
X}
X
X**********************************************************************
XSTEP 7): Run cvsync to retrieve the tree for the first time.
X
XLog in as or become the $CVSYNCUSER, and run
X
Xcvsync > /tmp/cvsynclog &; tail -f /tmp/cvsynclog
X
XIf you have cvsync permission, and have specified the correct host and
Xprefix in /etc/cvsync.conf you should see a list of files start
Xcoming in after a short while. Don't panic if nothing happens
Ximmediately. Watch for errors (cvsync can timeout or die). If you can't
Xaccess files contact the cvsync server maintainer. If you get a timeout
Xor if cvsync dies you can restart and it should continue where it left off.
X
XIt can take a good while (and a couple of restarts) to obtain the
Xwhole tree for the first time.
X
X**********************************************************************
XSTEP 8): Set up cron to keep the tree up to date.
X
XYou run cvsync periodically from the cron by setting up the crontab file
Xof the $CVSYNCUSER.
X
XFor example, to update every two hours:
X
X15 */2 * * * /usr/local/bin/cvsync > /dev/null
X
X**********************************************************************
XSTEP 9): Enabling OpenCVS anoncvs.
X
XThe next step is to enable OpenCVS, which will run on your system next
Xto the normal GNU cvs server. This will become the default in the
Xfuture.
X
XFirst off, create a new user account "opencvs" like you did for your
Xnormal anoncvs user:
X
Xopencvs::32766:32766::0:0:Anonymous OpenCVS User:/open/anoncvs:/open/anoncvssh
X
XBe sure that the uid and gid are unique for your system, if the ones
Xabove aren't, pick different values.
X
X#define OPENCVS_USER "opencvs"
X
XRecompile anoncvssh.c and install the binary setuid-root in /open/anoncvssh.
X
XCompile and install a current /usr/bin/opencvs.
X
XCopy /usr/bin/opencvs to /open/anoncvs/usr/bin/opencvs
X
XYou can now use OpenCVS anoncvs by using the correct CVSROOT:
X
X opencvs@anoncvs.openbsd.org:/cvs
X
XIf you encounter bugs, send them to joris@openbsd.org
