tdsavg isn't working:

controls@rossa:/opt/rtcds/caltech/c1/scripts/LSC 6$ tdsavg 10 C1:LSC-ASDC_IN1
ERROR: LDAQ - Unable to find NDS host "fb0"
ERROR: LDAQ - Unable to find NDS host "fb1"
ERROR: LDAQ - Unable to open socket to NDS.


When this command is executed inside a script, it doesn't return anything.  eg:

set offset = `tdsavg 10 C1:LSC_ASDC_IN1`
echo $offset

returns a blank line. 

Past elog research said lots of things about test points.  I didn't suspect that, since there aren't many test points occupied (according to the CDS status screens), but I cleared the test points anyway (elog 6319).  Didn't change anything, still broken.

LSCoffsets script, and any others depending on tdsavg will not work until this is fixed.
