Good morning, Quoting Holger Hans Peter Freyther (2014-11-15 03:11:46)
why does this need to go into the DB and not the configuration file?
Our first attempt was to do it in the configuration file, but we realized that vty doesn't have support for strings with spaces. Or did we miss something? We decided that was easier to add it to the database than to extend vty to parse strings with " or other way to support spaces.
What is your stand on checking the configured string for the right amount of printf placeholders?
You are right, this is not great. After discussing it with ciaby we decided that might make more sense to do something like: snprintf(sms_str, len, "%s IMSI: %s Token: %08X Ext: %s" auth_token_sms_text, subscr->imsi, token, subscr->extension); So the auth_token_sms_text don't have any placeholders it's just the introductory text.

Yes, it would be missing i18n.. but so does the entire OpenBSC codebase. I would really prefer to set this through the VTY than to put it into a database. Using ".TEXT" inside the VTY command string you can match more than just a single word. I think '%' is still not possible though. holger
