Hi all,
 I had and now again run into a connection problem. I am using SGI 44
 processors supercomputer. While I run multiple processor MD simulation with
 sander, it told me connection refused:
 permission denied
 rsh: connection failed
 PI file like:
 server.UT.ca 0 /aspirin/software/amber7/amber7/exe/sander
 server.UT.ca 1 /aspirin/software/amber7/amber7/exe/sander
 My computer have two name, one is "server.ut.ca", the other is
 "server.md.ut.ca". sander always try to find server.UT.ca . It is
 because I
 compiled sander before I used the name "server.MD.UT.ca". One account
 can
 run MD simulation but the other can not. These two accounts have same
 ~/.login ~/.cshrc. Could anyone give me some idea? Thanks a lot.
 Have a good day,
 William
