Hi,
sorry for the old note. I was on hurry.
Did you activate the gateway security (gw/acl_mode = 1)?
The registration of external server program is controlled by profile parameters (gateway security)
gw/acl_mode
gw_reg_info
gw/sec_info
If you don’t want to use gateway security, gw/acl_mode can be used to control registration of external programs on the system.
gw/acl_mode = 0 will deactivate gateway security and allow registration of external server program
gw/acl_mode = 1 will use gateway security and the files reg_info and sec_info needs to be maintained.
