Re: [sr-dev] [kamailio/kamailio] KEMI: kx subclass not found (#2196)
Thank you @miconda, super quick! Indeed I did not understand from where were being extracted all KSR.kx. functions. Fixed by adding `kemix` in `included_modules` before installing, and `loadmodule "kemix.so"` into the config. We might add clarification on [KEMI docs](https://kamailio.org/docs/tutorials/devel/kamailio-kemi-framework/modules/#kex) in order to avoid brain conflicts between KEMI, kemix, kex, and kx terms. We do you think? I'd be happy to add it if lgtm. Thanks again, closing. -- You are receiving this because you are subscribed to this thread.

[sr-dev] [kamailio/kamailio] KEMI: kx subclass not found (#2196)
## Description
Hello all, I'm migrating my Kamailio logics from legacy .cfg file to KEMI
script.
I began with Python but switched then to Lua, but there are some subclass /
functions described in KEMI documentation that seem not to be present in Lua
KSR object.
In this case, I am having trouble with the subclass "kx" described
[here](https://kamailio.org/docs/tutorials/devel/kamailio-kemi-framework/modules/#ksrkxget_srcip)
which is used in the default Lua script example
[here](https://github.com/kamailio/kamailio/blob/ca49dc0344f2ca4eae1999f6b46e0ab8c30bd1a3/misc/examples/kemi/kamailio-basic-kemi-lua.lua)
The error in the logs:
```bash
app_lua [app_lua_api.c:726]: app_lua_run_ex(): error from Lua:
/etc/kamailio/kamailio.lua:196: attempt to index field 'kx' (a nil value)
```
Referring to the following line in my Lua script:
```lua
function ksr_route_reqinit()
if not KSR.is_myself_srcip() then
local srcip = KSR.kx.get_srcip();
if KSR.htable.sht_match_name("ipban", "eq", srcip) > 0 then
-- ip is already blocked
KSR.dbg("request from blocked IP - " ..
KSR.pv.get("$rm")
.. " from " .. KSR.kex.gete_furi() .. "
(IP:"
.. srcip .. ":" ..
KSR.kex.get_srcport() .. ")\n");
KSR.x.exit();
end
if KSR.pike.pike_check_req() < 0 then
KSR.err("ALERT: pike blocking " .. KSR.pv.get("$rm")
.. " from " .. KSR.kex.gete_furi() .. "
(IP:"
.. srcip .. ":" ..
KSR.kex.get_srcport() .. ")\n");
KSR.htable.sht_seti("ipban", srcip, 1);
KSR.x.exit();
end
end
end
```
- Should this function be available through KSR object ? If yes we're talking
about an issue
Or
- Is this function not supported anymore / not with app_lua ? In this case we
should fix the documentation + the example script
### Troubleshooting
Debian Jessie
Kamailio 5.3
Lua 5.2
Reproduction
I tried different versions, all KO (Kamailio 5.2, 5.3, and last commit on
master: kamailio 5.4.0-dev3 (x86_64/linux) 5afe1e)
1. Install Debian Jessie
2. Clone Kamilio GIT
3. Build from source with make (enabling the desired modules before)
4. Insert Lua script (demo one is fine to reproduce my issue)
Debugging Data

Log Messages
```bash

SIP Traffic
Any message going through ksr_route_reqinit() function is triggering the error
Thanks !
