Ensure that the Kerberos server in i5/OS PASE on iSeries B has started

You need to ensure that the i5/OS™ PASE Kerberos server has started before you configure cross realm trust. You will use the process statistics command to determine whether the i5/OS PASE Kerberos server has started.

In a character-based interface on iSeries™ B, type call QP2TERM. This command opens an interactive shell environment that allows you to work with i5/OS PASE applications.
At the command line, enter ps -ef | grep krb5. This command indicates that you want to view all the processing statistics for every process on the system that contains the string krb5. If the Kerberos server is running, you might see results displayed that are similar to the following example:
```
> ps -ef | grep krb5
     qsys   113   1   0 08:54:04      -  0:00 /usr/krb5/sbin/krb5kdc
     qsys   123   1   0 08:54:13      -  0:00 /usr/krb5/sbin/kadmind
   $            
```
If the Kerberos server is not started, you might see the following results displayed:
```
> ps -ef | grep krb5
   $            
```

If the Kerberos server is not started, follow these steps:

At the command line, enter export PATH=$PATH:/usr/krb5/sbin, and press Enter.

Enter start.krb5, and press Enter.

 > start.krb5
   Starting krb5kdc...
   krb5kdc was started successfully.
   Starting kadmind...
   kadmind was started successfully.
   The command completed successfully.
