ip address from client

[Gerd Hilgemann]

hi,

is it possible to get the read the real external ip-address in lua?

like:
cur_client.ip ???

I study the documentation and can´t find any info about this.

Thx

client.address,

see wiki :-)

• address (read-only), address of the client.

yes...shame on me! i found the wiki..

dont know if someone can use it , but here is how i try to implement a geoIP check from the opensource maxmind in lua.

so maybe it´s not the best lua, code, let me know if you have some thoughts, i´m critical resident :)

in my lua script i detect and split each clientIP, 

function onConnection(client, userName, meeting)

clientIP = string.split2(client.address,":"); -- call a helper function to split the client ip adress from IP:PORT

after that send the IP to the geo IP module to receive the country:

ipdata = ip_to_country(clientIP[1]);

you can trace the continent like:

print("CLIENT CONTINENT: " .. ipdata.continent);

you also can get city infos, country code,

ipdata = ip_to_city(clientIP[1]);

-- Example geoIP

print(ipdata.country_code);

print(ipdata.country_name);

a simply check to allow only connection from germany

if (ipdate.country_name ~= "Germany") then

client.writer:writeAMFMessage("onPushData","Client is not allowed from his ip-address range to connect!")

error("Client is not allowed to connect");

end

really nice to see how you can extend the server with some scripts.

Interesting :-)

Yes, I love lua binding in Cumulus, and the fact that no restarting is required to modify a server application (dynamic load). One reason among others why I am working on Mona project :-).

Your code seems fine, just check well that no LUA call work in a blocking mode, otherwise you risk to decrease cumulus performance (the reason why I have been forced to rewrite LUASocket, see: https://github.com/OpenRTMFP/Cumulus/wiki/Server-Application,-Sockets)
