The iptables configuration on the DSMs only allows IP traffic from UCAR networks, 128.117, so you must be on the UCAR network to reach a DSM, such as with VPN.

Swamp DSMs

The 15 tripod sites all have Verizon U620L USB cell modems in the DSM for Internet access.  All the modems are configured for static IP addresses and registered with that static IP at dyndns.org, so you can refer them reliably either by name or IP.  Below are the sites.

I've started recording in the table which sites have external cell modems as far as I know.  I think other sites have external antennas that were installed during setup but without a ground plane.

Here is a plain ssh command for connecting to a site:

ssh daq@isfs14.dyndns.org

Here is a suggested ssh config for contacting a site:

Host isfs14
Hostname isfs14.dyndns.org
User daq
Port 22
HostKeyAlias isfs14
CheckHostIP no
LocalForward 8014 localhost:8888

The LocalForward opens a port on the originating host which connects to a proxy service running on the DSM, and the proxy service forwards to the cell modem's web interface.  So after connecting to a DSM with a host entry like the above, you can open this URL to connect to the cell modem on that DSM:

http://localhost:8014/myusb/

Be careful not to change the configuration or disconnect the modem.

Tower DSM

The tower DSM will not have a USB cell modem.  It connects back to the base trailer network over the Ubiquiti wireless link.  So to log into that DSM, you must be on the trailer network, such as logged into the base laptop eddy, and then you can connect like so:

ssh daq@192.168.0.116

NAGIOS Status

All of the swamp DSM are being monitored with a NAGIOS instance running in EOL.  You can view the status of all the ISFS sites with the URL below, but only within the UCAR network:

http://snoopy.eol.ucar.edu/nagios/cgi-bin//status.cgi?hostgroup=ISFS&style=detail

Login as 'guest' with an empty password.  In the excerpt below, host isfs1 is not responding to pings and so the background is pink, and since it is not on the net the SSH service is down also.  The DynDNS service is up because it only relies on dyndns.org for the hostname to resolve.  Host isfs10 is up and on the net and all services are OK.
