<br>
I started a 4-node EC2 cluster using 0.92rc2, and ami-a5c42dcc,
standard starcluster 9.04 x64 ami.<br>
<br>
I ran into the following issue while doing some basic sge setup.
At first qconf worked fine, then a few minutes later...<br>
<br>
root@master:/mnt/NAS1/simulations/CDI_0615_amazon/logs# qconf -sq
all.q<br>
error: commlib error: access denied (client IP resolved to host
name "domU-12-31-39-09-80-C1.compute-1.internal". This is not
identical to clients host name "master").<br>
<br>
after issuing<br>
<br>
root@master: ~# hostname master<br>
<br>
I was able to proceed normally, and launch my sge jobs. They were
running normally, confirmed by the output of qstat.<br>
<br>
However, some minutes later, when checking on them with another
qstat, I got the same thing again.<br>
<br>
root@master:/mnt/NAS1/simulations/CDI_0615_amazon/logs# qstat -f<br>
error: commlib error: access denied (client IP resolved to host
name "domU-12-31-39-09-80-C1.compute-1.internal". This is not
identical to clients host name "master").<br>
<br>
resetting the hostname was to no avail.<br>
<br>
root@master: ~ # hostname<br>
master<br>
root@master: ~ # hostname master<br>
root@master:/mnt/NAS1/simulations/CDI_0615_amazon/logs# qstat -f<br>
error: commlib error: access denied (client IP resolved to host
name "domU-12-31-39-09-80-C1.compute-1.internal". This is not
identical to clients host name "master").<br>
<br>
So I tried this <br>
<br>
root@master: ~# hostname
domU-12-31-39-09-80-C1.compute-1.internal<br>
<br>
which yielded, vice versa...<br>
<br>
root@master:/mnt/NAS1/simulations/CDI_0615_amazon/logs# qstat -f<br>
error: commlib error: access denied (client IP resolved to host
name "master". This is not identical to clients host name
"domU-12-31-39-09-80-C1.compute-1.internal")<br>
<br>
Setting the hostname back to master "hostname master") at this
point yields correct operation for a few minutes.<br>
<br>
<br>
It seems clear the problem has to do with doubled hostnames, but
where are they set? Has anyone else had a similar problem?<br>
<br>
Thank you,<br>

/etc/hostname is simply <br>
<br>
master<br>
<br>
<br>
/etc/hosts is below:<br>
<br>
127.0.0.1 localhost<br>
<br>
# The following lines are desirable for IPv6 capable hosts<br>
::1 ip6-localhost ip6-loopback<br>
fe00::0 ip6-localnet<br>
ff00::0 ip6-mcastprefix<br>
ff02::1 ip6-allnodes<br>
ff02::2 ip6-allrouters<br>
ff02::3 ip6-allhosts<br>
