Permission denied to [IP address]

[tommy_28]

Before install MCSG i use this command to create config template:

#cmquerycl -v -C /etc/cmcluster/cmclconf.ascii -n rp2470-B -n rp2470-A

but recieved:
Error: Permission denied to 192.168.1.85
Looking for other clusters ... Done
Error: Unable to establish communication to node rp2470-A
Failed to gather configuration information.

# more /.rhosts
rp2470-A root #cluster1
rp2470-B root #cluster2
rp2470-A oracle
rp2470-B oracle

#more /etc/hosts
192.168.1.86 rp2470-B
10.10.10.2 rp2470-B-h
127.0.0.1 localhost loopback
192.168.1.85 rp2470-A
10.10.10.1 rp2470-A

What can this happen?

Hi,

Does the rlogin between the two nodes run ?

Hi,
i think the problem can be the comments in the .rhosts file.

Try tearing them away.

Second: it's no a good thing (read unsopported) to have a hostname longer than 8 chars, and you have duplicate hostname fin the /etc/hosts:


192.168.1.86 rp2470-B
10.10.10.2 rp2470-B-h
127.0.0.1 localhost loopback
192.168.1.85 rp2470-A
10.10.10.1 rp2470-A

Change like the following:

192.168.1.86 rp2470-B
10.10.10.2 heartB
127.0.0.1 localhost loopback
192.168.1.85 rp2470-A
10.10.10.1 heartA



on both nodes.


I really suspect that the error comes from this second issue.


HTH,
Massimo

Now I've erased /.rhosts comments.
and change /etc/hosts hostname to more shorter, and different.

# more /.rhosts
rp2470-A root
rp2470-B root
rp2470-A oracle
rp2470-B oracle

#more /etc/hosts
192.168.1.86 rp2470-B
10.10.10.2 rp2470
127.0.0.1 localhost loopback
192.168.1.85 rp2470-A
10.10.10.1 rp2470

first, check the results of running nsllokup against each hostname and ip address.
second, check things like rlogin work

Hi,
is there a default gateway IP address in your /etc/rc.config.d/netconf?

try to put default_gateway in the /etc/hosts files:

default

Check for the hosts connectivity.

Enrico.

hi Tommy,
is it working now?

Also try creating a file called cmclnodelist and add the hostnames of nodes in the cluster Entries look similar to .rhosts file.

For ex:

nodename1 root
nodename2 root

Also look for inetd.sec in /var/adm/ for proper permissions were issued for opposite nodes.exec, shell,telnet, login should be allowed for the nodes in the cluster.

Goodluck

Thanks!
After I added the correct hostnames in cmclnodelist all works fine.
