Purpose: Entire station lost communication at about 1:30 today (while we were giving the tour of site5).
We've seen lots of reconnects in dyndns both since midnight last night and during the day yesterday.
Steps:
Cradlepoint WAN quick blinking/no USB or WLAN LED. Cycled power to cradlepoint. USB now on; WAN blinking; external connection via dyndns still not up, though www.dyndns does show request; am able to ssh in with IP address; data acquisition has been running.
See in messages that router_check ran, now access via isfs4.dyndns is working.
At Gordon's suggestion, did a bunch of tests of check_router script (which should have fixed this problem by itself). It has a long time-out of 3--5minutes, but did work as expected with the LAN cable unplugged. We next want to run a test by unplugging the 3G modem, but ran out of power on our laptop. We'll do this test tomorrow on the spare in the base.
