it looks to me that LM_ERR("command: [%.*s]\n", cmd->name.len, cmd->name.s); should be changed to LM_DBG("command: [%.*s]\n", cmd->name.len, cmd->name.s); since it is printed every time when imc_parse_cmd is called successfully. this does not still explain, why imc server does not send 200 ok response to the #join message. -- juha
