#!/usr/bin/env bash

for var in $@
do
	ret=$(echo $var | grep -P "(\w+@)?\d+\.\d+\.\d+\.\d+")
	if [ $? -eq 0 ]; then
		ipaddr=$var
		break
	fi
done

ipaddr=$(echo $ipaddr | awk -F@ '{ if (NF == 2) print $2; else print $1; }')

if [[ $ipaddr == 10* ]]; then
	/usr/bin/ssh -o ProxyCommand="/usr/bin/ssh $SSHD_PROXY -p 2222 -W %h:22" $@
else
	/usr/bin/ssh $@
