Implementing UNIX.SAMPLE.COM
We’ll start with UNIX.SAMPLE.COM. Both KDCs, unixkdc1.sample.com and unixkdc2.sample.com, have a fresh installation of the latest FreeBSD distribution. Two 18GB hot-swappable SCSI disks have been installed into each machine, and each box has a hardware RAID card set up to do mirroring across the installed drives. The partition layout looks like Table 9-1.
Table 9-1. Partition table for Unix hosts
Mount point | Description | Size |
/ | Root drive, includes all operating system programs and data | 5GB |
/krb5 | Kerberos database and software | 4GB |
/var | Log files | 5GB |
/tmp | Temporary files | 2GB |
swap | Kernel swap space | 1GB |
This layout gives ample room for Kerberos database growth, while enforcing the separation between the critical Kerberos database data and any log files or temporary files. A partition layout such as the one above ensures that these log files cannot fill up the entire disk, which may cause the operating system or Kerberos software to malfunction or, worse, corrupt the Kerberos database.
