source /environment.check.sh
 
#    . /etc/stb_params
PORTAL_1=`fw_printenv portal1 2>/dev/null`
PORTAL_1=${PORTAL_1#portal1=}
 
PORTAL_2=`fw_printenv portal2 2>/dev/null`
PORTAL_2=${PORTAL_2#portal2=}
 
PORTAL_TMP=`cat /ram/dhcp_ready | grep "portal_dhcp="`
PORTAL_TMP=${PORTAL_TMP%%#*}
PORTAL_TMP=${PORTAL_TMP#portal_dhcp=}

Example of services.js file (there is only part of file):
