Auto-generated random URL¶
Sometimes you need to install web applications which don’t have built-in authentication. A good solution can be an auto-generated random URL known only to some special users. It’s also a best practice to restrict access to those applications using Apache allow and deny rules.
This feature is implemented in nethserver-lib using
genRandomHash
function. The function will generate a SHA1 random
hash
Example from [[nethserver-collectd-web]]:
my $alias = $collectd->prop('alias') || "";
# initialize alias if needed
if ($alias eq "") {
$alias = esmith::util::genRandomHash();
$confdb->set_prop('collectd-web','alias',$alias);
}
Random alias should be generated inside an action, like
<package_name>-conf
. The action must be executed before
template-expand in a position before 05.
Example from createlinks:
my $event = "nethserver-samba-audit-update";
event_actions($event, qw(
initialize-default-databases 00
nethserver-samba-audit-conf 02
));
