pam_csync 0.42.0 beta2 at csync – file synchronization

pam_csync 0.42.0 beta2

10.28.08 - 04:48pm

This is the second beta release of csync 0.42.0. pam_csync is a PAM (Pluggable
Authentication Modules) module to provide roaming home directories for a
user session. This module is aimed at environments with central file servers a
user wishes to store his home directory. The Authentication Module verifies the
identity of a user and triggers a synchronization with the server on the first
login and the last logout.

There is a bug in several PAM applications calling the PAM functions on logout
in the wrong order. Take a look at:

gdm calls pam functions in the wrong order
http://bugzilla.gnome.org/show_bug.cgi?id=557794

OpenSSH calls pam functions in the wrong order on logout
https://bugzilla.mindrot.org/show_bug.cgi?id=1534

If you have ‘su’ (switch user) with pam support, check the patch
if it calls the functions in the right order.

You can find packages here.

ChangeLog

Improved debugging output
Fixed some PAM problems introduce by buggy gdm, su, openssh
Fixed kerberos support
Code cleanups

NOTE: If you want to use csync with sftp. Compile the latest libssh version from svn and apply this patch to the csync source.

I can not install csync. A have apt-get all packages that are needed but still gets the following.

According to http://packages.ubuntu.com/ you need:

libsqlite3-dev
libsmbclient-dev
liblog4c-dev

There is no libiniparser package so I think you have to compile it yourself.

Tobbera {Wednesday October 29, 2008 @ 2:24 pm}

Thank you for your support. I did
apt-get install libsqlite3-dev
apt-get install libsmbclient-dev

root@ubuntu:~/iniparser3.0b# make

Have you installed libiniparser?

install -m 0755 libiniparser.so.0 /usr/lib
install -m 0644 src/dictionary.h /usr/include
install -m 0644 src/iniparser.h /usr/include
ln -s libiniparser.so.0 /usr/lib/libiniparser.so

Tobbera {Wednesday October 29, 2008 @ 2:40 pm}

Now the cmake worked! Thank you!
The make does not complete though;

Yes, there is a bug with Samba 3.0.x. I’ve already fixed it. Look here:

https://dev.csync.org/changeset/a825dd3e14c45064ce343f018f1f519dd5aedfc8/modules/csync_smb.c

Tobbera {Wednesday October 29, 2008 @ 3:17 pm}

That worked! The make install also.

Now I’m trying to do the pam_csync:

root@ubuntu:~/pam_csync-0.41.94/build# cmake -DCMAKE_BUILD_TYPE=Debug ..
– Found Iniparser: /usr/lib/libiniparser.a
CMake Error: Could not find PAM

root@ubuntu:~/pam_csync-0.41.94/build#

Appreciate your help!!

Tobbera {Wednesday October 29, 2008 @ 3:29 pm}

Did apt-get install libpam-dev
Worked.

Tobbera {Wednesday October 29, 2008 @ 4:13 pm}

Trying:
root@ubuntu:~/csync-0.41.95/build# csync

Tobbera {Wednesday October 29, 2008 @ 4:28 pm}

Did install -m 0644 src/libcsync.so.0 /usr/lib/
Worked.

Seems like the sftp module were never compiled:

How do I do this?
Thanks!

GlaDiaC {Wednesday October 29, 2008 @ 4:44 pm}

Well this is only possible with a patched version of libssh.

See http://www.csync.org/2008/09/17/csync-and-pam_csync-0420-beta1/

Tobbera {Wednesday October 29, 2008 @ 5:11 pm}

I see…

I’ve downloaded the libssh-dev source and the patches. Can you tell me how I compile the libssh with the patches?

Regards

GlaDiaC {Wednesday October 29, 2008 @ 5:31 pm}

You have to download the source apply the patches and compile it yourself.

Tobbera {Wednesday October 29, 2008 @ 7:38 pm}

I’ve patched the source:
root@ubuntu:~/libssh-0.2# patch -p1 < ../0002-Map-permission-field-to-type-field.patch
root@ubuntu:~/libssh-0.2# patch -p1 < ../0001-Map-permission-field-to-type-field.patch
and compiled it fine.

But i still get:
root@ubuntu:~/libssh-0.2# csync /tmp/sqlMvRp3a user@host.homelinux.org/tmp/
[stderr] 20081029 17:34:26.019 WARN csync.statedb- sqlite version mismatch

Hi All,

I`ve the same problem.
I can`t use the csync.

That`s my problem:

stderr] 20090325 18:48:40.284 WARN csync.statedb- sqlite version mismatch
[stderr] 20090325 18:48:40.284 WARN csync.statedb- sqlite3_compile error: no such table: metadata – on query SELECT COUNT(phash) FROM metadata LIMIT 1 OFFSET 0;
[stderr] 20090325 18:48:40.284 NOTICE csync.statedb- statedb doesn’t exist
[stderr] 20090325 18:48:40.285 FATAL csync.time- Access dienied to remote uri:

I don`t know what my problem is (csync or sqlite3).

Any guy can help me?

thanks a lot…

Hélio

GlaDiaC {Thursday March 26, 2009 @ 12:03 am}

Hey,

@Toberra: The url ist wrong! It should be:

csync /tmp/sqlMvRp3a sftp://user@host.homelinux.org/tmp/

See the userguide or manpage!

–

@hpadrao: The problem is not the statedb. The problem seems to be the access to the server.

If you want to use sftp I suggest to use the latest libssh svn version and csync with the following patch:
