L2TP VPN IPSEC не подключался

Я столкнулся с той же проблемой на своем Ubuntu 14.10, решение просто убивает Chrome каждый раз, когда он питается CPU, вот мой сценарий для этого, он работал над моим делом.

#!/bin/sh

#ps aux  | awk 'BEGIN { sum = 0 }  { sum += $3 }; END { print sum }'

# DON VI PHAN TRAM
MAX_ALLOWED_CPULOAD=50
MAX_ALLOWED_MEMLOAD=50
core_num=$(nproc)
MAX_ALLOWED_CPULOAD=$(expr $MAX_ALLOWED_CPULOAD \* $core_num)

counter=0
continue_high_cpuload_count=0
max_continue_alowed=10

print_cpu_load_with_pid(){
    cpuload=$(ps aux  | awk 'BEGIN { sum = 0 }  { sum += $3 }; END { print sum }')
    cpuloadpercent=$(echo "100 * $cpuload / $MAX_ALLOWED_CPULOAD" | bc)
    echo "checked at $counter times, cpuload = $cpuloadpercent %"
    counter=$((counter+1))
    #$(echo 12.45 10.35 | awk '{if ($1 < $2) print $1; else print $2}')
    decide=$(echo $cpuload $MAX_ALLOWED_CPULOAD | awk '{if ($1 > $2) print "true"; else print "false"}')
    if [ "true" = "$decide" ] ; then
        continue_high_cpuload_count=$((continue_high_cpuload_count+1))  
        echo "High cpuload detected, continue_counter = $continue_high_cpuload_count"
    elif [$continue_high_cpuload_count -gt 0 ]; then
        continue_high_cpuload_count=0
        echo "No longer detect hight cpu, reseting continue_counter..."
    fi

    if [ "$continue_high_cpuload_count" = "$max_continue_alowed"  ] ; then
        echo "Killing chrome..."
        kill -9 `ps -aux|grep chrome|awk '{print$2}'`
    fi
}

while [ : ];do
    print_cpu_load_with_pid
    sleep 2
done
