I got it working finally. Took a slightly different route:
1. created a script /etc/init.d/hamtun
Code:
#!/bin/bash
# script to load tuncfg then hamachi at boot
sudo /usr/src/tuncfg/tuncfg
sudo /usr/src/hamachi/hamachi start
2.
Code:
chmod +x /etc/init.d/hamtun
3. execute this command to link the script to boot
Code:
update-rc.d hamtun defaults
4. reboot...and it works.
One note: tuncfg was loading all along, but not in the right order. If I remove the "tuncfg" line from this script and JUST load "hamachi start", it does not work because hamachi is being loaded before tuncfg. So, I suspect when I am loading tuncfg in this script it is getting loaded again elsewhere at boot - but that doesn't hurt anything.
Thanks all for the help!
