The files /etc/ssh/cozsftp_config and /etc/ssh/cozsftp_server_config determine the session settings for the Co:Z SFTP client and server respectively. The permissions for each of these files should be 0644.

Samples of both of these files are located in the /usr/lpp/coz/samples directory. These samples may be customized and placed at the above locations to make them active.

Each file has two sections, fixed: and default:

# Fixed section

# Specify fixed settings following this line
# -- for the following line, see IBM APAR OA34819
ssh-le-options=HEAP(8M,1M,,FREE),ENVAR("_CEE_REALLOC_CONTROL=256K,25")

# Default section        
default: 
# Specify default settings following this line

	Use this section to specify site-wide options that cannot be overridden by individual users. Multiple options may be specified on a single line if separated by commas.
