Hello list, quick question following the rcons thread - we would like the service nodes to run the conserver daemon, however, we would also like to open the rcons / wcons from the management node. right now i'm getting the following messages -
xcatmn:~ # rcons idp1
sn2: access from your host refused
Is there any modification needed to the conserver.cf file?
this is the access part of it (192.168.70.100 is my management node).
access * {
trusted 127.0.0.1;
trusted 192.168.70.100;
trusted 192.168.70.3,192.168.10.3,sn2,sn2-eth1,localhost;
}
thx in advance!

HI, sorry for my late response, I was out of office in the last several
days.
The conserver is made as a subsystem for the AIX SRC(System Resource
Controller), if your AIX SN was setup correctly, the conserver should be
already a SRC subsystem, you can run lssrc to check:
p5n03:/#lssrc -s conserver
Subsystem Group PID Status
conserver 8257974 active
p5n03:/#
if you got error "0513-085 The conserver Subsystem is not on file", then
you can manually create the subsystem:
mkssys -p /opt/freeware/sbin/conserver -s conserver -u 0 -S -n 15 -f 15 -a
"-o -O1 -C /etc/conserver.cf"
Thanks,

Have you set the "conserver" of the nodes to be the service node? If the
conserver is set, at least the file /etc/conserver.cf should be created on
the SN.
Thanks,

Hi,
I'm running xcat 2.7.5 on MN and SN. i should mention that MN is linux and
SN is AIX.
On the MN all local ip addresses are in the trusted section of
/etc/conserver.cf the SN doesn't have the file /etc/conserver.cf.
