The default location for the configuration files is /etc/ssh2 for the global configurations and $HOME/.ssh2 for the user-specific configuration files. You can edit the ssh2_config and ssh-socks-proxy-config.xml files with your favorite text editor.
The ssh2_config configuration file contains keyword-value pairs, one per line. Lines starting with the hash character (#) as well as empty lines are interpreted as comments and ignored. For more information on the client configuration options, see the ssh2_config man page (Appendix ssh2_config).
The ssh_ftadv_config configuration file contains file transfer profiles used by scp2 and sftp2. The file does not exist by default, but can be enabled by copying the example profile file /etc/ssh2/ssh_ftadv_config.example to /etc/ssh2/ssh_ftadv_config (globally for all users) or $HOME/.ssh2/ssh_ftadv_config (for a specific user). For more information on the file transfer advisor configuration options, see Section File Transfer Profiles.
