New subject: Kamailio : kamctl address reload with HAProxy

28 Mar 2022

Hello,

please keep the list in CC – that others can comment as well.

Can you actually connect from the kamailio system e.g. with mysql client? If yes, as I
said – I would try to debug the issue further with network analysis tools.

Cheers,

Henning

Hello,

KAMCTL :

I've resolved the problem with kamctl that now can communicate with my remote Cluster
by adding this line in kamctlrc.

// HAPROXY = 192.168.1.37
DBHOST=192.168.1.37
DBACCESSHOST=192.168.1.37

I can now add and reload new addresses with success.

KAMAILIO + HAPROXY:

But now, I've this issue when restarting kamailio.

Mar 28 10:54:39 kamailio /usr/sbin/kamailio[8416]: ERROR: permissions [address.c:233]:
reload_address_db_table(): database problem - invalid record
Mar 28 10:54:39 kamailio /usr/sbin/kamailio[8416]: ERROR: permissions [permissions.c:657]:

[core/sr_module.c:942]: init_mod(): Error while initializing module permissions
(/usr/lib/x86_64-linux-gnu/kamailio/modules/permissions.so)

My DBURL is

#!substdef "!DB_USER!kamailio!g"
#!substdef "!DB_PASS!XXXXX!g"
#!substdef "!DB_HOST!192.168.1.37!g"      // HA PROXY
#!substdef "!DB_PORT!MY_PORT_DB!g"
#!substdef "!DB_NAME!kamailio!g"

#!define DBURL "mysql://DB_USER:DB_PASS@DB_HOST/DB_NAME"

KAMAILIO + REMOTE DB :

Even I using a remote database I'm getting the same issue.
I've discovered the connection between kamailio and remote database is aborded
instantly after restarting kamailio.

Mar 28 11:47:30 db03srv mariadbd[874]: 2022-03-28 11:47:30 44076 [Warning] Aborted
connection 44076 to db: 'kamailio' user: 'kamailio' host:
'192.168.1.41' (Got an error reading communication packets)

Thank you

Hello,

it seems the data that gets delivered to the Kamailio is corrupted. Analyse it further
e.g. with a network trace, wireshark etc..

Cheers,

Henning

Subject: [SR-Users] Kamailio : kamctl address reload with HAProxy

Dear colleagues,

I've installed a Galera cluster with a HAProxy that kamailio interacts with.
Kamailio's DBURL is linked to the proxy that will contact the databases.
Kamailio works fine except when I need to reload something from the database (Using
kamctl).

When cache and database are the same I receive

sudo kamctl address reload
{
  "jsonrpc":  "2.0",
  "result": "Reload OK",
  "id": 13111
}

Now when I have something using kamctl, it still works and is replaced on all my
databases.

sipsecure@kamailio:~$ sudo kamctl address add 0 192.168.48.15 32 0 Test
-e \E[37;33mINFO: execute '/sbin/kamctl address reload' to synchronize cache and
database

 Then when i try to reload i receive

sipsecure@kamailio:~$ sudo kamctl address reload
{
  "jsonrpc":  "2.0",
  "error":  {
    "code": 500,
    "message":  "Reload failed."
  },
  "id": 13504
}

And when I'm going to read my logs to see a error, I only see that little sentence

Mar 25 17:14:40 kamailio /usr/sbin/kamailio[13343]: ERROR: permissions [address.c:233]:
reload_address_db_table(): database problem - invalid record

Could I have some explanation ?

Thank you.
