Network naming key:
|Name Pattern||Device category|
|<site>b||DSMs at the bottom of the tower, all Titans except for one Viper.|
DSMs at the top of the tower, all Raspberry Pi.
|u<site>||Ubiquiti radios serving as clients, aka station adaptors (SA).|
|tv||Three Ubiquiti radios on the TV tower serving as access points (AP).|
|<site>||DSMs at sites with only a single DSM, all Raspberry Pi.|
|base,iss,...||Ubiquiti SA radios for ISFS base trailer, ISS, and other guest platforms.|
The ssh config below should work to connect to ustar during staging at EOL, and possibly during operations depending on what ports we can forward on the public-facing router.
The ssh tunnel is also up and working, so this configuration should work both in staging and during operations.
ustar it is possible to
ssh to any of the DSMs by name.
LocalForward allows the local browser to connect to Nagios on ustar using this URL: http://localhost:15380/nagios/. Use
Station connection status:
|Station||Connection method||Working?||Notes||Radios||Uplink AP||Power Schedule||Plans|
|NW1||ubiquiti||yes||installed G2 relay AP for nw2/3, but neither have been able to connect. unw1ap radio has been removed and unw1 connected directly to dsm.||G2 unw1||tv|
|NW2||cell||yes||40' Rohn, cell signal at the base of the tower (verizon). Could not connect to relays at either nw1 or nw4. Installed Verizon cell 7/26.||G2 unw2, turned off 7/26|
Add a directional cell antenna when available.
|NW3||cell||yes||PAM. USB modem with AT&T SIM, directional antenna. Web interface reports 3 bars, 4G LTE.|
|Did this radio already got removed?|
|NW4||ubiquiti||yes||PoE passthru from unw4 to unw4ap turned off 7/27|
GU unw4ap, off
|NE1||ubiquiti||yes||winch repaired, raised, une1 connects to tv||G2 une1||tv|
relay installed: G2 une3ap as AP for une4
|NE4||ubiquiti||yes||too much high ground between site and WLEF, use une3ap relay||G2 une4||une3ap||off 9-5|
|SE3||ubiquiti||yes||G2 use3ap installed bearing 125 degrees to catch se6 and also se4, but se4 signal is weak; the relay to both se6 and se4 might be better with a LiteAP AC, but I didn't order one||G2 use3|
|SE4||ubiquiti||yes||installed G2 use4, has weak signal to use3ap||G2 use4|
|SE5||ubiquiti||yes||40' Rohn, Gordon climbed to adjust bearing to 160 degrees, sufficient signal to use6ap relay||G2 use5||use6ap||off 9-5|
|SE6||ubiquiti||yes||locked to AP use3ap; turning off power overnight||G2 use6|
ISFS-M21 22.214.171.124, sw1-isfs.dyndns.org
radio removed; rsync working from ustar over cell (ISFS-303)
|SW2||ubiquiti||yes||100' Rohn, sees both tv1 and tv2, apparently just needed to be switched to PtMP mode||G2 usw2||tv|
|SW3||ubiquiti||yes||relay radio removed|
Radio model key:
- G2 - NanoBeam AC Gen2, model NBE-5AC-GEN2-US
- M16 - NanoBeam M5, model NBE-M5-16
- M5 - NBE-5AC-16
The current thinking is to turn off radios overnight on towers with two radios to reduce power consumption, and then also at sites which depend on those relays. For example, turning off the relay at se3 cuts off three sites: se3, se6, and s5. See Radio power schedule installed blog entry.
The final sites have been added to the net using cell modems: nw2 and nw3, Rohn and PAM sites with a single DSM at the ground. The USB sticks at those sites are easy to access and swap. Gordon tried an AP at nw4 to see if it catches nw2 and nw3, but that didn't work either. At the moment, nw3 has a directional antenna. It would probably help nw2 to have a directional antenna also, once one is shipped to the field.
se5 is online, but barely. The rsync seems to be keeping up mostly, but sometimes it can fall behind by several hours.
If data from a tower trailer needs to be collected by sneaker net, then we have to come up with a scheme like running an rsync on site (very slow) or continuously sync'ing data from the top DSM to the bottom DSM and then periodically swapping the bottom USB stick. At the moment that seems unlikely to be needed.
