??? 1.1.0
|
||||
- Lamdaemon now uses the SSH implementation from PECL which is much more stable
|
||||
|
||||
Developers:
|
||||
API changes:
|
||||
- removed $post parameters from module functions (delete_attributes(),
|
||||
process_...(), display_html_...()). Use $_POST instead.
|
||||
- process_...() functions: returned messages are no longer grouped
|
||||
(e.g. return: array(array('INFO', 'headline', 'text')), array('INFO', 'headline2', 'text2')))
|
||||
(e.g. return: array(array('INFO', 'headline', 'text'), array('INFO', 'headline2', 'text2')))
|
||||
|
||||
10.08.2006 1.0.4

Setting up lamdaemon:
|
||||
|
||||
Attention! The old version of lamdaemon is no longer supported. However,
|
||||
if you do not install libssh2 then LAM will fall back to the old mechanismn.
|
||||
If you want to stay with the old lamdaemon then change your /etc/sudoers entries
|
||||
to point to lamdaemonOld.pl.

e.g. "$admin All= NOPASSWD: /srv/www/htdocs/lam/lib/lamdaemon.pl"

At the moment the password is a paramteter of lamdaemon.pl
|

therefore you should disable logging so the password does not

appear in any logfile.
|

This can be done by adding the following line to /etc/sudoers:

$admin is the admin user from LAM (must be a valid Unix account)
|
||||
and $path is the path to lamdaemon.pl
|

3. Setup Perl
|
||||
==============
|
||||
|
||||
We need an extra Perl module - Quota
|
||||
To install it, run:
|
||||
|
||||
perl -MCPAN -e shell
|
||||
install Quota # required
|
||||
install Net::SSH::Perl # required
|
||||
install Math::BigInt::GMP # optional but very poor performance if not installed
|
||||
install Quota
|
||||
|
||||
If your Perl executable is not located in /usr/bin/perl you will have to edit
|
||||
the path in the first line of lamdaemon.pl.
|
||||
If you have problems compiling the Perl modules try installing a newer release
|
||||
of your GCC compiler and the "make" application.
|
||||
|
||||
Debian users can install Net::SSH:Perl with dh-make-perl:
|
||||
|
||||
apt-get install dh-make-perl
|
||||
dh-make-perl --build --cpan Net::SSH::Perl
|
||||
dpkg -i libnet-ssh-perl_1.25-1_all.deb
|
||||
Several Linux distributions already include a quota package for Perl.
|
||||
|
||||
|
||||
4. Set up SSH
|
||||
4. Install libssh2
|
||||
==================
|
||||
|
||||
4.1 Install libssh2
|
||||
You can get libssh2 here: http://www.libssh2.org
|
||||
Unpack the package and install it by executing the commands
|
||||
"./configure", "make" and "make install" in the extracted directory.
|
||||
|
||||
4.2 Install SSH2 for PHP
|
||||
The easiest way is to run "pecl install ssh2-beta". If you have no pecl command then install
|
||||
the PHP Pear package (e.g. php-pear or php5-pear) for your distribution.
|
||||
|
||||
If you want to compile it yourself, get the sources here: http://pecl.php.net/package/ssh2
|
||||
|
||||
|
||||
5. Set up SSH
|
||||
=============
|
||||
|
||||
Your SSH daemon must offer the password authentication method.
|
||||
To activate it just use this configuration option in /etc/ssh/sshd_config:
|
||||
|
||||
PasswordAuthentication yes
|
||||
|
||||
|
||||
5. Test lamdaemon.pl
|
||||
There is a test-function in lamdaemon.pl. Please run lamdaemon.pl
|
||||
with the following parameters to test it:
|
||||
|
||||
lamdaemon.pl $ssh-server $lam_path_on_host $admin-username $admin-password *test
|
||||
|
||||
$ssh-server is the remote host lamdaemon.pl should be run on
|
||||
$lam_path_on_host is the path to lamdaemon.pl on remote host
|
||||
$admin-username is the name of the user which is allowed to run lamdaemon.pl
|
||||
as root. It is the same user as in /etc/sudoers
|
||||
$admin-password is the password of the admin user
|
||||
*test is the command which tells lamdaemon.pl to test settings
|
||||
|
||||
You have to run the command as the user your webserver is running, e.g.
|
||||
|
||||
wwwrun@tilo:/srv/www/htdocs/lam/lib> /srv/www/htdocs/lam/lib/lamdaemon.pl \
|
||||
127.0.0.1 /srv/www/htdocs/lam/lib/lamdaemon.pl adminuser secret *test
|
||||
|
||||
You should get the following response:
|
||||
|
||||
Net::SSH::Perl successfully installed.
|
||||
Perl quota module successfully installed.
|
||||
If you have not seen any error lamdaemon.pl should be set up successfully.
|
||||
|
||||
|
||||
!!! Attention !!!
|
||||
Your password in LDAP has to be hashed with CRYPT. If you use something like SSHA
|
||||
you will probably get "Access denied.".
|
||||
|
||||
Now everything should work fine.

6. Debugging lamdaemon
|
||||
If you set up all things as documented before and still get "Access denied"
|
||||
then you can try to debug the problem.
|
||||
======================
|
||||
|
||||
- Check /var/log/auth.log or the equivalent on your system
|
||||
This file contains messages about all logins. If the ssh login
|
||||
failed then you will find a description about the reason here.
|
||||
|
||||
- Enable debug output in lamdaemon
|
||||
In line 235 of lamdaemon.pl change the SSH options like this:
|
||||
|
||||
my $ssh = Net::SSH::Perl->new($hostname, options=>[
|
||||
"UserKnownHostsFile /dev/null"],
|
||||
protocol => "2,1", debug => 1 );
|
||||
|
||||
This will produce a lot of output when you do the lamdaemon test.
|
||||
Check that there is a line like this:
|
||||
|
||||
Authentication methods that can continue: publickey,password,keyboard-interactive.
|
||||
|
||||
The "password" is the one which is important.
|
||||
|
||||
- Set sshd in debug mode
|
||||
In /etc/ssh/sshd_conf add these lines:

Security warning:
|
||||
-----------------
|
||||
|
||||
If you use PHP < 4.3 your admin user and password are passed as commandline argument.
|
||||
This can be a security risk. Upgrade your PHP version for productive use.

Setting up lamdaemon:

||||
|
||||
|
||||
LamdaemonOld.pl is used to modify quota and home directories on a remote or local host via ssh.
|
||||
If you want wo use it you have to set up some things to get it to work:
|
||||
|
||||
|
||||
1. Setup values in LDAP Account Manager
|
||||
* Set the remote or local host in the configuration

|
||||
* Path to lamdaemonOld.pl, e.g. /srv/www/htdocs/lam/lib/lamdaemonOld.pl
|
||||
If you installed a Debian or RPM package then the script may be located at
|
||||
/usr/share/ldap-account-manager/lib or /var/www/html/lam/lib.

2. Set up sudo

|
||||
$admin-username is the name of the user which is allowed to run lamdaemonOld.pl
|
||||
as root. It is the same user as in /etc/sudoers
|
||||
$admin-password is the password of the admin user
|
||||
*test is the command which tells lamdaemonOld.pl to test settings
|
