The typical behavior # is to start up one instance of ftp-proxy by setting ftpproxy_enable and # ftpproxy_flags. The alternate behavior allows multiple instances of ftp- # proxy to be started, allowing different types of proxy behavior. To use the # new behavior, a list of instances must be defined, and a list of flags for # each instance. For example, if we want to start two instances of ftp-proxy, # foo and bar, we would set the following vars. # ftpproxy_enable="YES" # ftpproxy_instances="foo bar" # ftpproxy_foo="<arguments for foo>" # ftpproxy_bar="<arguments for bar>" # # Starting more than one ftp-proxy? if [ "$ftpproxy_instances" ] && [ -n "${ftpproxy_instances}" ]; then # Iterate through instance list. for i in $ftpproxy_instances; do #eval ftpproxy_${i}_flags=\$ftpproxy_${i} #eval name=ftpproxy_${i} # Set flags for this instance. eval ftpproxy_flags=\$ftpproxy_${i} # Define a unique pid file name. pidfile="/var/run/ftp-proxy.$i.pid" run_rc_command "$1" manage_pid $1 done else # Traditional single-instance behavior run_rc_command "$1" fi
