819c537b5e Improve /dev/ppp check 
- Show a warning instead of exiting with an error for missing /dev/ppp,

a0409b4399 Cleanup 
- In rare cases, if a parent process traps SIGPIPE, the 'tr'
  command in the VPN setup scripts could output an error
  'tr: write error: Broken pipe'. This is a cosmetic error
  that does NOT affect the functionality of the scripts. This
  commit hides the error in such cases.

2b6586cf1b Increase IKE lifetime 
- Set both "ikelifetime" and "salifetime" to 24 hours, which is

  normally initiate rekey with a shorter interval.
