Automatically restart Logmein Hamachi
Jun 24, '14 07:00:00AM • Contributed by: Anonymous If you are having trouble with Logmein Hamachi starting up correctly, the following script will check to see if the connection is up. If it is, it will attempt to restart and then send you an email when it's done.
You'll need to update these variables with your own data:
email_address='XXXXXXX@gmail.com'hamachi_network="xxx-xxx-xxx"Also update the machine names and IP address (e.g. test_ip_address) in the case statement.
You can use the command hamachi list (from a Terminal window) to get your network ID and IP addresses.
Once you set this up, you can run this from any of your connected machines and it will try to connect to the other machine. If it cannot, it attempts to get Hamachi working again.
Here's the script:
#!/bin/bash# Script to restart the Hamachi connection if it is not working## user command "hamachi list" to find the hamachi network you are connecting to# email_address='XXXXXXX@gmail.com'hamachi_network="xxx-xxx-xxx"public_ip_address='google.com' # machine_name=`uname -n`case $machine_name in Mac1.local) test_ip_address="25.xxx.xxx.xxx" test_machine="Mac1" ;; Mac2.local) test_ip_address="25.xxx.xx.xx" test_machine="Mac2" ;; *) echo "You are using an unknown machine, named [$machine_name]. Exiting" exit ;;esac echo "Checking Logmein Hamachi network connectivity..."echo "You are using [$machine_name]. Checking IP Address [$test_ip_address] on [$test_machine]"IS=`/sbin/ping -c 5 $public_ip_address 2> /dev/null | grep -c "64 bytes"`if (test "$IS" -eq "0") then echo "Your internet connection does not appear to be working. Aborting check" exitfi IS=`/sbin/ping -c 5 $test_ip_address 2> /dev/null | grep -c "64 bytes"`if (test "$IS" -gt "2") then echo "Your Logmein Hamachi connection appears to be working." exitelse echo "There appears to be a problem with your Logmein Hamachi connection." echo "I will check again in 10 seconds..." sleep 10 IS=`/sbin/ping -c 5 $test_ip_address 2> /dev/null | grep -c "64 bytes"` if (test "$IS" -gt "2") then echo "Your Logmein Hamachi connection appears to be working now." exit else echo "There is still a problem with your Logmein Hamachi connection. Attempting to fix by restarting Logmein Hamachi..." hamachi logout sleep 10 hamachi login sleep 10 hamachi go-offline $hamachi_network sleep 10 hamachi go-online $hamachi_network echo "OK, we should be back up!" echo "Your Logmein Hamachi connection on $machine_name needed to be cycled on/off. Could not connect to [$test_ip_address]. It may also mean that $test_machine is down." | mail -s "Hamachi Connection Down on $(date '+%m/%d/%y @ %H:%M:%S')" $email_address -f ipdown@no-reply.com -F "Hamachi Connection Problem on $machine_name" fifi[crarko adds: I haven't tested this one.] •
