Chapter 3. HMC overview and planning 99
Enable or disable remote command execution
This option allows you to enable or disable the ability to run remote commands to the HMC
from a remote client using the SSH protocol. PuTTY would be an example of a remote client
using the SSH protocol. The commands that can be executed are restricted.
Enable or disable remote virtual terminal
This option allows you to enable or disable the ability to run a remote virtual terminal on the
HMC. An example would be using a 5250 client on a remote PC to access a OS400 partition.
The remote client connects to the HMC by using the HMC’s IP address. Multiple remote 5250
virtual terminals can be connected to the one partition. At the same time, care should be
taken, as commands typed on one virtual terminal will display on the other terminals
connected to the same partition. This function is useful for remote support.
Change current locale
This option allows you to change the locale (language) used by the HMC. The default is a US
English locale. Some of the other optional languages available are:
Spanish
French
Hungarian
Japanese
Italian
Russian
Slovak
German
Note that in some languages, certain words and phases may not translate. Locale can be
changed at any time and only requires an HMC reboot.
3.6 Service applications
The service applications are used to service the managed systems from a central point. The
applications are divided into four options, as follows:
Problem determination
Inventory Scout services
Service focal point
Remote service
3.6.1 Problem determination
The problem determination option allows the service support organization to view the HMC
internal code and determine how to fix a software problem. Only service support personnel
can access this option.
