Troubleshooting: Specific Problems

/etc/hosts
----------
15.136.120.169 jacko.bbn.hp.com jacko
193.1.1.1 jacko.bbn.hp.com jacko_x.25

and restart ITO.

2. In cases where it is not possible to add host name/IP-address

associations (for example, in fire-wall environments), a special ITO
configuration file can contain the association (this configuration file
must be created manually):

/etc/opt/OV/share/conf/OpC/mgmt_sv/opc.hosts

------------------------------------
193.1.1.1 jacko.bbn.hp.com

Then restart ITO.

It is also required that all IP-addresses of the management server are
known by ITO. You can do this by either specifying all host
name/IP-address associations in the name service, or by specifying it in
the

opc.hosts

file as shown in the following example:

Management server “arthur.bbn.hp.com”
/etc/hosts
----------
193.1.4.1 arthur.bbn.hp.com arthur 193
15.136.121.2

arthur.bbn.hp.com arthur

192.1.1.1

arthur.bbn.hp.com arthur-fddi

Note that ITO uses the fully qualified hostname for identifying a
managed node or management server, and for resolving the
IP-addresses. Therefore, the name service entries of the following
example will not solve the above problem:

/etc/hosts
----------
193.1.4.1 arthur.bbn.hp.com arthur 193
15.136.121.2.

arthur.bbn.hp.com arthur

192.1.1.1

arthur.bbn.hp.com arthur-fddi

In this case, the resolution of arthur. bbn.hp.com would only return
193.1.4.1, and not all three addresses.

IP Connectivity.

You can check IP-connectivity by using the

ping(1M)

command as follows:

# ping 193.1.4.1
