Hi all!
can anyone tell me how to check the syntax of the openser.cfg file after
adding code for new modules? also after saving the file with the changes in
it, should the execute permissions be set to it? currently my openser.cfg
does not have execute permission for anyone ie owner or user or group.
Please let me know asap
Thanks and Regards,
Padmaja
