Miscellaneous Administrator Tasks

This chapter describes miscellaneous administration tasks for Internal Directory mode including:

•Redefining Hostname, Domain Name, and Country Code

•Data Migration from Release 1.4 to 1.5

•Recovering Your System Password

Redefining Hostname, Domain Name, and Country Code

If you want to redefine Cisco 2116 system network information; such as hostname, domain name, and country/location code without destroying the directory data and templates, use the relocate command.

The relocate command is designed to backup and erase existing directory data so that you can redefine the Cisco 2116 system network information using the Setup program.

Step 1 Log in as root.

Use your root password.

Step 2 Type relocate.

This program performs the same tasks as reinitialize, except that it backs up all data that you can restore when you run Setup. It also saves the configuration templates.

Step 3 Run Setup to redefine the desired system network information (see Cisco Configuration Engine Installation & Setup Guide, 1.5 for Linux).

Data Migration from Release 1.4 to 1.5

The Data Migration function allows you to upgrade your system to from Release 1.4 to Release 1.5, then populate your directory with the data you established for the prior release. This is a three-step process:

1. Export data to a remote FTP site.

2. Install Release 1.5 software.

3. Retrieve data from the FTP site and setup the system.

Export Data to Remote FTP Site

Before exporting the data, it is assumed that the Cisco 2116 has already been setup and is up running.

Step 1 Insert the Release 1.5 CD-ROM into the CD drive of the Cisco 2116 to be upgraded.

Step 2 To mount the CD, log in as root.

Step 3 Type:

mount /mnt/cdrom

Step 4 Change directory into:

/mnt/cdrom/DataExport

Step 5 Issue the data export command:

./dataexport

Tip Make sure you type the period (.) prior to the command.

Step 6 Follow the sequence of prompts to enter information of the FTP site and storage location (absolute pathname including filename).

Following are the prompts of dataexport:

Notes

Sample user inputs are shown in bold text. 

Entering Data Export

Type ctrl-c to exit


Enter FTP server (hostname.domainname or IP address): sername.cisco.com

Enter DNS server IP address: 171.69.226.120

Enter username used for FTP server: smith

Enter FTP password: *****

Re-enter FTP password: *****

Enter absolute pathname of data file on FTP server: /users/smith/migration.tar

Install Release 1.5 Software

To re-image the system, while the Release 1.5 CD-ROM is still in the CD drive:

Step 1 Enter the sync command two times:

[root@mainstreet root]# sync

[root@mainstreet root]# sync

Step 2 Restart the system by pressing the Reset button.

Run datamigrate and Setup System

After the system rebooted from the new installation, the following prompts appear: 

This Appliance is not configured.

Please login as setup to configure the appliance.

localhost.localdomain login:

Step 1 Log in as root with password blender.

Step 2 Start data migration with the command:

datamigrate

The script proceeds in three stages:

1. Acquire information of the FTP server that stores the migration data and retrieve the data.

2. Start new release Setup prompts and setup the system.

3. Populate directory storage with retrieved data.

Following are the prompts of datamigrate:

Notes

Sample user inputs are shown in bold text. 

You must configure eth0 or eth1. Press <Enter> to skip!


Enter eth0 IP address: 10.1.19.102

Enter eth0 network mask: 255.255.255.0

Enter eth0 default gateway IP address: 10.1.19.6

Enter FTP server (hostname.domainname or IP address): sername.cisco.com

Enter DNS server IP address: 171.69.226.120

Enter username used for FTP server: smith

Enter FTP password: *****

Re-enter FTP password: *****

Enter absolute pathname of data file on FTP server: /users/smith/migration.tar

Running Datamigratation in External Directory Mode

Step 1 Insert the 1.5 CD on a running 1.4 system.

Step 2 Run dataexport and back up the data file.

Step 3 Manually make the necessary changes to the LDAP schema of the external directory.

Step 4 Manually create a new CE-context for 1.5 and create other containers (for devices, applications, IMGW, etc.) under that context per new 1.5 requirements.

Step 5 Install 1.5, then run datamigrate.

Recovering Your System Password

Step 1 Restart the Cisco 2116 system.

The system shuts down, and restarts. After the appliance restarts, you should see the boot image screen (Figure 21-1).

Figure 21-1 Boot Images

Step 2 Use the arrow keys to select (highlight) a boot image.

Select linuxserial for setting up the serial port as console. You can select linuxvga if you are connected by means of a local VGA connection.

Step 3 Press the E key to edit the boot parameters (see Figure 21-2).

Figure 21-2 Boot String

Step 4 Using the arrow keys, select the entry kernel /vmlinuz.2.4.20-19.7 ro root=/dev/sda7 console=ttyS0,9600n8.

Step 5 Press the E key to enter the editor.

Step 6 Go to the end of the line, and add single after the parameter console=ttyS0,9600n8: 

kernel /vmlinuz.2.4.20-19.7 ro root=/dev/sda7 console=ttyS0,9600n8 single

Step 7 Press Enter.

You might not see this parameter added to the previous screen due to screen size.

Note This parameter tells the kernel to start in single user mode.

Step 8 Press the B key to start the system in single-user mode.

After the system initialization, you see a root prompt, without having to type in a username or password: 

[... sys init messages ...]

Turning on user and group quotas for local filesystems: [ OK ]

Enabling swap space: [ OK ]

sh.2.04#


Step 9 At this prompt, enter the command passwd and enter the new (strong) password for the root user: 

sh.2.04# passwd

New UNIX password:

Retype new UNIX password:

passwd: all authentication tokens updated successfully

sh.2.04#


Step 10 After you change the password, enter reboot, and let the machine start normally.

Step 11 When prompted for a name, enter root.

Step 12 When prompted for the password, type the new password.
