I've restarted the NDS2 process on Megatron so that we can use it for getting past data and eventually from outside the 40m.
1) from /home/controls/nds2 (which is not a good place for programs to run) I ran nds2-megatron/start-nds2
2) this is just a script that runs the binary from /usr/bin/ and then leaves a log file in ~/nds2/log/
3) I tested with DTT that I could access megatron:31200 and get data that way.
There is a script in usr/bin called nds2_nightly which seems to be the thing we should run by cron to get the channel list to get updated, but I' m not sure. Let's see if we can get an ELOG entry about how this works.
Then we want Jamie to allow some kind of tunneling so that the 40m data can be accessed from outside, etc.

I have done the following:
* installed the nds2-client in /ligo/apps/nds2-client
* moved the nds2 configuration directories to /ligo/apps/nds2/nds2-megatron
* set up a cron job to update the channel list every morning at 5 am. The cron line is:
15 5 * * * /usr/bin/nds2_nightly /ligo/apps/nds2/channel-tracker /ligo/apps/nds2/nds2-megatron
cron will send an email each time the channel list changes, at which point you will have to restart the server with:
cd /ligo/apps/nds2/nds2-megatron
pkill nds2
./start-nds2
* restarted nds2 with updated channel lists.
