Hi,
I want something like that:
# define some router to use later in the script (global section)
Mod_param(router(1), "10.10.10.1")
mod_param(router(2), "10.10.10.2")
mod_param(router(3), "10.10.10.3")
Mod_param(router_count, "3")
within the different routes I want to loop through the routers like that:
$var(i)
while($(var(i) < $var(router_count)) {
if ($var(router($var(i)) == src_ip") {
.. do something
}
}
Is that somehow possible?
Any hint or idea is appreciated!
Best regards,
Bernhard Suttner

htable module should do the trick to you.

Another option is to push the constants into AVP arrays at startup (I
assume there is some sort of init route at this point, otherwise a
module init event-route):
$(avp(s:routers)[0]) = "10.10.10.1";
$(avp(s:routers)[1]) = "10.10.10.2";
$(avp(s:routers)[2]) = "10.10.10.3";
You can then iterate through them, using is_avp_set() to check if
something exists at the current index/array subscript:
$var(i) = 0;
while(is_avp_set("$(avp(s:routers)[$var(i)])")) {
xlog("L_INFO", "Router is: $(avp(s:routers)[$var(i)])\n";
$var(i) = $var(i) + 1;
}

Hi,
yeah, that looks like a good solution. But I assume that there should be the similar way
to use the shm or pseudo variables as a array. Maybe someone else does know more about
this way?

Bernhard

the script variables that can hold arrays are AVPs. You can emulate
arrays with htable by constructing an array-like key - what Juha
suggested. I haven't checked/used the memcache module.
What Alex provided for assignment is not working exactly that way,
because an assignment to an AVP always adds at the first position like a
stack (the index is not relevant for avp in the left side of assignment
unless it is '*' and assigned value is null - meaning delete all avps
with that name).
However, as I understand you want to execute some actions based on
source IP. Look at permissions module, with 3.1 you can assign tag value
per ip/network address. This value is returned in config upon matching
and based on it you can do specific operations.
There are other modules that could be used to match based on ip address,
without a need to do a loop in config.
Cheers,
Daniel

Bernhard

That is true. I forgot about that. That still means he could insert
the IPs in backward order, though, doesn't it?

Hi,
thanks @ all. I will try out the AVP method.

beware that normally the avps are
persistent per transaction. Meaning
that when the transaction processing (or the message in stateless mode)
is done, avps are removed automatically.
There are global avps coming from ser 2.0 (therefore you have to use
version 3.0+) where the name has to contain 'g.' prefix - $avp(g.foo)

Ok. Thx. And where could I add the global variables (the configured routers)? I would like
to have them in the global section (like the mod_param).

1:28 p.m.
The module permissions with the function allow_source_address is exactly what I want to
do. Check where the call is coming from and do something special to it. Thanks a lot for
that great module (and of course to 3.1 and to the nice help which I got here :-)
