Title: Weekly antivirus scan scheduling
Post by: uli334 on September 24, 2022, 07:41:06 AM

Hello,

is there a way to set the weekly virus-scan to a scheduled time?

Thank you for answer.
Uli

if you know what you're doing, hack /etc/crontab through its template /etc/e-smith/templates/etc/crontab/clamav
first copy it to /etc/e-smith/templates-custom/etc/crontab/clamav , modify line 10, then set again weekly scans

Code: [Select]

# cat /etc/e-smith/templates/etc/crontab/clamav
{
    my $min = substr(gmtime,14,2);

    $OUT .= "\n";
    $OUT .= "# smeserver-clamscan filesystem scan\n";
    my $ScanFreq = $clamav{FilesystemScan} || 'disabled';
    if ($ScanFreq eq 'daily') {
        $OUT .= $min."\t0\t*\t*\t*\troot\t/sbin/e-smith/smeserver-clamscan\n";
    } elsif ($ScanFreq eq 'weekly') {
        $OUT .= $min."\t0\t*\t*\t6\troot\t/sbin/e-smith/smeserver-clamscan\n";
    } else {
        $OUT .= "# disabled\n";
    }
}


the line of interest for you is

Code: [Select]

        $OUT .= $min."\t0\t*\t*\t6\troot\t/sbin/e-smith/smeserver-clamscan\n";
it is currently set to run on the 6th and last day (Saturday, as 0 is Sunday, 1 is Monday...) at hour 0:$min
where $min is the minute at which the template has been expanded the last time.

Thank you for help,

made it like you told.

Don't i have to expand this template like " /sbin/e-smith/expand-template /etc/crontab "?

Greetings, Uli

yes you have to expand.

please do not modify the template, create a template custom or your mods will be deleted on next update

That's what i've done:

- mkdir -p /etc/e-smith/templates-custom/etc/crontab
- cp /etc/e-smith/templates/etc/crontab/clamav /etc/e-smith/templates-custom/etc/crontab
- nano /etc/e-smith/templates-custom/etc/crontab/clamav
- in the row " $OUT .= $min."\t0\t*\t*\t6\troot\t/sbin/e-smith/smeserver-clamscan\n"; " changed "t6" to "t5"
then:
- /sbin/e-smith/expand-template /etc/crontab

Right? Or some kind of failure in it?

This is:

Code: [Select]

# smeserver-clamscan filesystem scan
49      0       *       *       5       root    /sbin/e-smith/smeserver-clamscan
Looks good!
Thank you very much for help!
