Gabriel,
How about we cheat? The script below (starting with: #!/bin/sh) should
work whether it is IP or hostname.
Try this script:
##### BEGIN SCRIPT ######
#!/bin/sh
CLIENT=$(echo $DISPLAY | cut -d: -f1)
CLIENT1=$(echo $CLIENT | cut -d. -f1)
CLIENT1_CHECK=$(echo $CLIENT1 | sed -e 's/[0-9]*//g')
USER_PREFIX="auto"
if [ -z "${CLIENT1_CHECK)" ]; then
# CLIENT is an IP
echo "${USER_PREFIX}$(echo $CLIENT | cut -d. -f4)"
exit 0
else
# CLIENT is a hostname
echo "${USER_PREFIX}$(echo $CLIENT1 | sed -e 's/^[a-zA-Z0]*//')"
exit 0
fi
##### END SCRIPT ######
