[IDD #GTN-647623]: Traceroute request



Hi Art,

I just logged onto idd.cise-nsf.gov as 'ldm' and ran a traceroute back
to idd-ingest.meteo.psu.edu:

/opt/ldm% traceroute idd-ingest.meteo.psu.edu   
traceroute to idd-ingest.meteo.psu.edu (128.118.28.130), 30 hops max, 40 byte 
packets

 5  beast-internet2-gi2-0.3rox.net (192.88.115.24)  15 ms  10 ms  10 ms

/opt/ldm% traceroute -n idd-ingest.meteo.psu.edu
traceroute to idd-ingest.meteo.psu.edu (128.118.28.130), 30 hops max, 40 byte 
packets
 1  192.12.209.1  0 ms  0 ms  0 ms
 2  206.196.177.137  1 ms  1 ms  1 ms
 3  206.196.178.90  2 ms  2 ms  2 ms
 4  206.196.178.46  3 ms  2 ms  2 ms
 5  192.88.115.24  10 ms  9 ms  10 ms

The lists are abbreviated because the traceroutes hung (or, at least, did not 
continue
for the 5 minutes I waited).

An 'ldmping', on the other hand worked quickly:

Sep 10 1ldmping idd-ingest.meteo.psu.edu
Sep 10 19:11:23 INFO:      State    Elapsed Port   Remote_Host

Sep 10 19:11:48 INFO: RESPONDING   0.013920  388   idd-ingest.meteo.psu.edu  
 ...

Cheers,

Tom
