known bugs

There are still some bugs in this RPM... Help us to fix them!

ipdiscover bug

We need to confirm that ipdiscover works when the smeserver is the forced client.

I Tried the following:

ipdiscover eth0 10

	Note:
	Usage : ipdiscover [iface name] [latency in ms]

Here's what I got on my server:

<IPDISCOVER>
<H>192.168.0.100<M>00:xx:xx:xx:xx:xx</M><N>pc-00100.mydomain.com</N></H>
<H>192.168.0.253<M>00:xx:xx:xx:xx:xx</M><N>pc-00253.mydomain.com</N></H>
<H>192.168.0.254<M>00:xx:xx:xx:xx:xx</M><N>pc-00254.mydomain.com</N></H>
</IPDISCOVER>

Sounds like it's working for me... But IpDiscover discovers nothing when launched by SME OCS' Agent. There must be a problem here!

Windows Agent don't have this problem...

deployment deletion bug

When you delete a package, ocs complains, but it deletes the files anyway, document later

Stefen

The only way I was able to reproduce an error on package deletion is when I refreshed the page (as files were already removed, I got an error)

Could you be more clear on this bug? How did it happened?

add a package, deploy > activate > click on the red X

ERROR: Can't delete directory /opt/inventory/ocs/download/1194511477

I have documented that you can ignore the error, maybe i should say if you see the error you can ignore?

future RPM

What will be fixed in next RPM release...

upload size limit

Max allowed packet value is locked at 10M by default on SME.

Let's delete the mysql custom-template in the future RPM!

We can modify this value to only affect the ocs directory.

Add the following lines to Apache template:

<Directory /opt/inventory/ocs/ocsreports>
..
php_admin_value post_max_size $ocs{'MaxUpload'}
php_admin_value upload_max_filesize $ocs{'MaxUpload'}

Apply changes:

config setprop ocs MaxUpload 50M
expand-template /etc/httpd/conf/httpd.conf
/etc/init.d/httpd-e-smith condrestart

set $ocs{'MaxUpload'} defaulting to something in the rpm, 10M or more ?

aliases

Future RPM will allow to add aliases using 'URL' value to ocs and glpi

{
  if (exists $foo{'URL'})
  { $OUT .= "Alias  /$foo{'URL'}  /opt/foo\n"; }
}

RPM is not a chatroom

Less chat in the install output, just say look at the renamed wiki page

events

Don't use signal-event my-own-event: just give all the commands, or use an existing one, we could use domain-modify

Here's the future createlinks perl script:

#!/usr/bin/perl -w
use esmith::Build::CreateLinks qw(:all);

# Templates to adjust
templates2events("/etc/e-smith/sql/init/80ocs_mysql.sql",          qw(domain-modify post-upgrade ));
templates2events("/etc/e-smith/sql/init/82glpi_mysql.sql",         qw(domain-modify post-upgrade ));
templates2events("/etc/e-smith/sql/init/84ocs-glpi.sql",           qw(domain-modify post-upgrade ));
templates2events("/etc/ocsinventory-agent/ocsinv.conf",            qw(domain-modify post-upgrade ));
templates2events("/opt/inventory/glpi/config/config_db.php",       qw(domain-modify post-upgrade ));
templates2events("/opt/inventory/ocs/ocsreports/dbconfig.inc.php", qw(domain-modify post-upgrade ));
# Services to restart
safe_symlink("start",           "root/etc/e-smith/events/domain-modify/services2adjust/mysql.init");

Apache is already expanded and restarted by event domain-modify so I removed these useless lines... Events are also available when calling a post-upgrade. I based this on how SME handles webmail and also what I've found in other SPRMs...

How I handle SME integration:

80ocs_mysql.sql  => create/update ocs  database+user+password
82glpi_mysql.sql => create/update glpi database+user+password
84ocs-glpi.sql   => apply ocs' password in glpi database
ocsinv.conf      => apply Agent config
config_db.php    => MySQL DB passwords
dbconfig.inc.php => MySQL DB passwords

	Warning:
	These templates allow to restore the good password when using www/ocs/install.php (used for web interface updates!!!)

	Note:
	These templates also ensures that if ocs password changes, it will be updated in glpi MySQL database!!!

	Note:
	These templates are working for RPM install, RPM updates and everyday use :-)

save bandwidth

Create a separate RPM with the ocsagent.exe and guide.pdf and make it a dependency of the main RPM...

Or maybe not?

=> files deleted in the tarball, this is 1.5MB + 6MB

=> ocsagent.exe needs to be installed anyway with www/ocs/install.php

People should download latest client and put ocsagent.exe in www/ocs/files

Will document this later

=> figured out why the guide.pdf is needed: there a link to it the web interface...

People can download this file... Or not, let's warn that the help page won't be accessible in OCS!

I think there is no need to put them as requires. I can put the guide.pdf in my folder and give the link in the wiki.

MySQL init scripts

/etc/e-smith/sql/init/* should only be used one to create the db table, then it is deleted
httpd.conf and php.ini are in standard events (and are we still changing php.ini?)
which only leaves three fragments to document in the rare case that something changes

Yes, all that goes in /etc/e-smith/sql/init/ is dropped after a successful importation. I know that, I use it this way:

• 3 templates to dynamically create the DB+User+Password and change OCS' password in GLPI' database. These templates are harmless if re-expanded...

• 2 databases (one for ocs, one for glpi). They are imported ONLY ON NEW INSTALL. These 2 databases are dropped once imported (no need to keep them!)... It also allows me to import the right GLPI database according to $LANG

So when the RPM runs:

• 3 files loaded on RPM updates
• 5 files loaded on RPM install

Take a look on their name when all 5 files are put in /etc/e-smith/sql/init/ once expanded

dependencies

change the install method to install the perl dependencies that are available from existing repos.

Then you can reduce the number of perl rpms in your download the less you are responsible for the better

yum localinstall smeserver-inventory-tools* --enablerepo=?

ocsagent.exe

I'm not sure this is needed, lets delete it from the server and see if it affects anything before removing from the rpm,

stephen

About ocsagent.exe, it doesn't help you when you've installed the Agent, but if you use the standalone OCSLogon.exe to send inventories, the client will not download needed files. This file is needed!

By the way, we need to document that: next time the Agent version changes, this file needs to be upgraded too!

new accounts

2 'url' accounts types will be created for ocs:

root/etc/e-smith/db/accounts/defaults/ocsinterface
root/etc/e-smith/db/accounts/defaults/ocsinventory

These virtual locations are used by ocs server-side.
