lamdaemon.pl is used to modify quota and homedirs
|
||
|
|
on a remote or local host via ssh.
|
||
|
|
If you want wo use it you have to set up many
|
||
|
|
thins to get it work.
|
||
|
|
|
||
|
|
1. Set values in LDAP Account manager
|
||
|
|
* Set the remote or local host in the configuration
|
||
|
|
(e.g. 127.0.0.1)
|
||
|
|
* Path to lamdaemon.pl, e.g. /srv/www/htdocs/lam/lib/lamdaemon.pl
|
||
|
|
|
||
|
|
|
||
|
|
2. Set up sudo
|
||
|
|
The perlskript has to run as root (very ugly I know but
|
||
|
|
I haven't found any other solution). Therefor we need
|
||
|
|
a wrapper, sudo.
|
||
|
|
Edit /etc/sudoers on host homedirs or quotas should be used
|
||
|
|
and add the following line:
|
||
|
|
$admin All= NOPASSWD: $path
|
||
|
|
$admin is the adminuser from lam and $path
|
||
|
|
is the path include the filename of lamdaemon.pl
|
||
|
|
e.g. $admin All= NOPASSWD: /srv/www/htdocs/lam/lib/lamdaemon.pl
|
||
|
|
At the moment the password is a paramteter of lamdaemon.pl
|
||
|
|
Therefore you should disable logging so the password doesn't
|
||
|
|
apear in any logfile
|
||
|
|
This can be done by adding the following line:
|
||
|
|
Defaults:$admin !syslog
|
||
|
|
|
||
|
|
3. Set up perl
|
||
|
|
We need some external perl-modules, Quota and Net::SSH::Perl
|
||
|
|
Th install them, run:
|
||
|
|
perl -MCPAN -e shell
|
||
|
|
install Quota
|
||
|
|
install Net::SSH::Perl
|
||
|
|
Please answer all questions to describe your system
|
||
|
|
Every additional needed module should be installed
|
||
|
|
automaticly
|
||
|
|
LDAP isn't used by lamdaemon.pl anymore
|
||
|
|
|
||
|
|
I installed Math::Pari, a needed module, by hand.
|
||
|
|
I had many problems to install Math::Pari, a module needed
|
||
|
|
by Net:SSH::Perl. The reason is a bug in gcc 3.3 (In my case).
|
||
|
|
I found the following solution to prevent this bug:
|
||
|
|
* Download and untar pari (http://www.parigp-home.de)
|
||
|
|
* Download and untar Math::Pari
|
||
|
|
* run perl Makefile.PL
|
||
|
|
* edit Makefile and libPARI/Makefile
|
||
|
|
Replace line "OPTIMIZE = -O3 --pipe" with
|
||
|
|
"OPTIMIZE = -O1 --pipe".
|
||
|
|
* run make
|
||
|
|
* run make install
|
||
|
|
|
||
|
|
4. Set up ssh
|
||
|
|
On my System, Suse 9.0 I had to set usePAM no in /etc/ssh/sshd_config
|
||
|
|
to get lamdaemon.pl work
|
||
|
|
I had some problems to log in with ssh if the password hash of the
|
||
|
|
admin-user was encrypted with {SSHA}. I had to change encryption
|
||
|
|
for admin-accounts to {CRYPT} to get ssh work.
|
||
|
|
|
||
|
|
5. Test lamdaemon.pl
|
||
|
|
I've installed a test-function in lamdaemon.pl. Please run lamdaemon.pl
|
||
|
|
with the following attributes 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
|
||
|
|
$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's the same user in /etc/sudoers
|
||
|
|
$admin-password is the password of admin-user
|
||
|
|
*test is the command which tells lamdaemon.pl to test settings
|
||
|
|
|
||
|
|
You have to run the coammd as the user your webserver is running as, 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 root secret *test
|
||
|
|
|
||
|
|
You should get the following response:
|
||
|
|
Net::SSH::Perl successfully installed.
|
||
|
|
sudo set up correctly.
|
||
|
|
Perl quota module successfully installed.
|
||
|
|
If you have'nt seen any error lamdaemon.pl should set up successfully.
|
||
|
|
|
||
|
|
Now everything should work fine
|
||
|
|
|
||
