daily2 server restart hangs when run with CRON about anet

[Nielk1]

Note: An attempt was made for the server to auto-detect this state in the restart2 script which is run every 5 min to restart the server if it is offline and correct it. A special program syntest2 will attempt a SYN, SYN-ACK, ACK handshake with the server and if it fails, trigger a restart. Like the daily2 script, this fails to start the server in a functional state when run via CRON but works when executed by user. This script does however properly detect the server is in this inaccessible state in both cases.

This is caused by the CRON not properly keeping shell variable scope. The scripts can be adjusted to work around this, but it is only an issue if using shell vars to work around automatic IP detection issues.
