Installation and Upgrades / UPS module on Zentyal 2.x
« on: June 19, 2013, 10:21:58 pm »
Hi

Has anyone done it or has anyone an idea how to install Zentyal 3.0's UPS module on a Zentyal 2.2.9?
I know how to install apcupsd on a Zentyal Server but I'd like to (fully) integrate my UPS into Zentyal (and can't change to V3 at the moment).

Thanks for any suggestions,
Peter

Hi

I'm running a Zentyal 2.2 and keep it updated (by GUI and after facing the problem also with "apt-get update"/"apt-get upgrade").
On Dec, 7th I had to shut down the server due to works to be done on the electrical power inhouse. After restarting I could not get to the internet from LAN (the config: internet<--->Zentyal<--->LAN). Zentyal has access to the internet.

 Perhaps iptables or your kernel needs to be upgraded.

It seems like the kernel and the modules don't fit.

--------------------8<--------------------

For me it seems like kernels 2.6.32-43 to 2.6.32-45 were installed.
But they don't appear in grub's list and the are not in /boot (only 2.6.32-34 up to 2.6.32-42).

I can't remove an old kernel with "apt-get remove linux-image-2.6.32-34-generic". I get a message like "package not installed and therefore nothing to remove".


Please help


BTW: my bluetooth dongle isn't found with "hcitool scan" anymore, too. It returns "Device is not available: Address family not supported by protocol"

Installation and Upgrades / Backup Tool reports an error
« on: March 24, 2012, 09:31:06 am »
Hi out there

I daily get an error message (at 4 am - can't find an according cronjob though) that says:
"Use of uninitialized value $value in concatenation (.) or string at /usr/share/perl5/EBox/RemoteServices.pm line 1861."

Line 1861 in RemoteServices.pm reads: $stringConf .= "$entry,$type,$value\n";
And here is the complete sub with the trouble making line of code:
Code: [Select]
sub _statusKeysAndValuesString
{
    my ($self) = @_;
    my $stringConf;

    my $type = 'string';
    my @dirsToLook = ('');
    while (@dirsToLook) {
        my $dir = shift @dirsToLook;
        push @dirsToLook, $self->st_all_dirs($dir);

        my @entries = @{   $self->st_all_entries($dir) };
        foreach my $entry (@entries) {
            my $value = $self->st_get_string($entry);
            $stringConf .= "$entry,$type,$value\n";       /* <-- this is THE line of trouble */
        }
    }

    return $stringConf;
}

Any idea what's going wrong and how it can be fixed?

Installation and Upgrades / How can I read sysadms mails?
« on: March 13, 2011, 12:41:05 pm »
There are a lot of interesting mails in /var/mail/sysadm.
I'd like to read them with a standard mail program (i.e. Thunderbird) from a client computer in the network. I tried several parameters (protocol, server name, port, authentication...) to access the mailbox but didn't succeed.
Can anyone help?

I want to restrict some computers access to the internet. Of course I can put them into an object. But i can identify the members of an object only by IP address (and optional by MAC address).
As IP addresses are dynamic (I use DHCP) and easily can be changed I'd rather identify a computer only by its MAC address.
Can I do that?
How can i do that?

Help appreciated, Peter

Installation and Upgrades / integrate personal changes
« on: October 27, 2010, 09:22:58 pm »
Hi

I want to configure a few things on my own (eg. in /etc/postfix/main.cf). That works fine.
But when I configure the server with the web interface my "personal" changes are often overridden.
Is there a way (a file) to make my changes persistent?

Thanks for any suggestions or tipps, Peter
