[torqueusers] Unauthorized Request

I ran into exactly the same issue installing on Natty. The solution for me
was to modify the /etc/hosts file from the Ubuntu default. I have pasted
below some notes that I made on fixing the issues in our install.

Best,
Mike

 The installation instructions at
http://www.clusterresources.com/torquedocs21/1.1installation.shtml worked
very well, up to a few glitches (which cost several days) described below:
the first with recognizing the proper host address (fixed by editing the
/etc/hosts file) and the second due to problems with password-less ssh for
scp file transfer from the compute nodes back to the head (fixed using
ssh-keygen and setting the proper permissions).

 The online installation instructions say simply to go to the torque-2.4.8
directory and type (as sudo):

 $ ./configure

$ make

$ make install


 I found that in addition, before running Torque (probably better before
installation), the file /etc/hosts needs to be modified from the Ubuntu
default. *In place of *the first few lines (the ipv4 part) reading

 127.0.0.1 localhost

127.0.1.1 <host domain name>

 < more stuff about IPv6 >

  (the lines here are the Ubuntu 11.04 default) one should add the actual
(static, internal) ip addresses of both the head and compute nodes:

 127.0.0.1 localhost

<static internal ip for host> <host domain name>

<static internal ip for compute #1> <compute node #1 domain name>

<static internal ip for compute #2> <compute node #2 domain name>

 < same stuff about IPv6 >


 For example, if your head node domain name is headnode (local static ip
192.168.1.100) and you have two compute nodes named compute-0-0 and
compute-0-1, the /etc/hosts might look like

 127.0.0.1 localhost

192.168.1.100 headnode

192.168.1.253 compute-0-0

192.168.1.254 compute-0-1

 < same stuff about IPv6 >


This is important so that the pbs_server recognizes the head node as the
actual host -- otherwise, it will be confused and try doing things like
communicating with "root at localhost" instead of "root@<domain name>" (i.e.
“root at headnode” in our example). The problem is that both 127.0.0.1 and
127.0.1.1 are ip addresses which point to the computer itself. One needs the
actual static ip of headnode in the second line or either (1) the qmgr on
the head node will not recognize the head node itself or (2) the compute
nodes will try communicating with "127.0.0.1" (i.e. themselves) rather than
with the head node.
