The SSH Tectia SOCKS Proxy component used in transparent FTP tunneling and FTP-SFTP conversion does not use the regular client configuration ssh-broker-config.xml. Instead, the configuration is read from the ssh-socks-proxy-config.xml file.
Like the ssh-broker-config.xml file, the ssh-socks-proxy-config.xml file can be located in the system-wide /opt/tectia/etc directory and/or in the user-specific $HOME/.ssh2 directory.
The SOCKS Proxy reads the user public keys and server host keys from the normal locations ($HOME/.ssh2 and $HOME/.ssh2/hostkeys). However, if the server authenticates itself using a certificate, the information on the CA certificate (or the server certificate) must be defined separately in the ssh-socks-proxy-config.xml file.
