[arm-allstar] SSH quits working

[Steve Arntz]

While adjusting the /usr/local/etc/allstar.env  to get rid of DNS errors I
found that a START_DELAY of 4 or more resulted in SSH not working anymore.
As best I could tell, everything else was working fine including
supermon2.  I just could not log in remotely anymore.  I made a visit to
the site today
and adjusted the value back to 2 and SSH is working correctly now.  Not
sure what this is, but wanted to let others know about it in case they ran
into
the same failure.  We are running HAMVOIP Version 1.6-12 Allstar - June 05,
2020 - KB4FXC, WA3DSP  on a RPi4b with 4 Gb of ram. The
firewall is currently enabled.  I verified I could duplicate the problem by
making it fail again.  Also checked status of sshd and everything appeared
normal to me from the system console.
