[Swift-devel] Re: Problem with incorrect host cert DN in coaster GSI authentication

Fri Apr 30 10:09:04 CDT 2010

Hi Mike

I think I've found the problem ,   In coasters.log , there is an  entry 
shows  that /qstat/ OR qdel can not be  found.  so I hard link all the 
binaries in /opt/torque-2.3.6/bin to /usr/bin, and then i get a 
successfully response.

this is not an perfect solution, it would be ideal to send the 
environment setting through profile files rather than make this hack on 
remote site, but anyway i can get coaster to work now.

Many Thanks!!!
