General description
CHARON-AXP provides the following set of utilities:
<source disk file name> - a file name of the disk image to be transferred
<source disk parameters> - the name of the disk from the list provided by the "mkdskcmd --list" command execution or the disk geometry specification (see below).
- --shrink or -k - used in the case where the target disk is transferred to a smaller disk.
Example:
$ mkdskcmd --transfer /etc/rz22.vdisk rz25 |
It is also possible to specify the disk parameters manually with "--blcount / -c" (blocks count) and "--blsize / -z" (blocks size) switches:
$ mkdskcmd --transfer <source disk file name> -blsize <number> -blcount <number> |
Example:
$ mkdskcmd -t /etc/custom.vdisk -z 512 -c 262134 |
| Warning |
|---|
There is a certain delay between the moment when the utility reports that a disk image has been transferred and its actual availability to CHARON. This delay can reach to several minutes in case of very big disks transfers. It happens because the host operating systems needs some time for actual allocation of the enlarged file on HDD. |

Creating disk images
The "mkdskcmd" utility:
- Creates empty disk images of a given standard disk type or a custom disk size
- Transfers existing disk images of one type to disk images of another type.
The first step is to obtain the name of the disk that needs to be created:
$ mkdskcmd --list |
This command results in a list of all supported disk types.
Choose the desired disk (for example "RZ22"), then use the "mkdskcmd" command to create the virtual disk image as shown below:
$ mkdskcmd --disk rz22 --output rz22.vdisk |
A disk container "rz22.vdisk" will be created in the current directory.
| Info |
|---|
A file "rz22.avdisk" will also be created. This file helps CHARON accurately recognize a specific disk image type. It is recommended to put the ".avdisk" file in the same directory as the created disk image. |
It is also possible to create custom disk images using "--blcount" (blocks count) and "--blsize" (blocks size) switches.
To get all the available parameters please use the "–help"switch:

Return value: 0 - for Success Non zero - in case of failure
Examples: mkdskcmd -h mkdskcmd -l mkdskcmd -a /opt/charon/utils/mkdsk.vtable -o /etc/rk07.vdisk -d rk07 mkdskcmd -o /etc/custom.vdisk -z 512 -c 16384 mkdskcmd -t /etc/rz22.vdisk rz25 -a /opt/charon/utils/mkdsk.vtable mkdskcmd -t /etc/rz22.vdisk rz25 -a /opt/charon/utils/mkdsk.vtable -z 512 -c 262134
The "--avtable" parameter is used to work with an alternative disk specification database (or to point to the standard database ("mkdsk.vtable") if it is in a location other than the current directory).
The "--blcount" (blocks count) and "--blsize" (blocks size) switches are used to create custom disk images.
Transferring disk images
The "mkdskcmd" utility is able to transfer (copy) disk images of one type to a disk image of another type.
This operation is needed, for example, to obtain more free space on a disk image that already contains data.
Note: it is not possible to add more free space dynamically. CHARON-AXP must be stopped before performing this operation.
| Info |
|---|
If a source disk image is larger than the target disk image, the extra data is lost. If the source disk image is smaller, it will be extended and padded with null bytes ('\0'). |
An example of the syntax follows:
$ mkdskcmd --transfer <source disk file name> <source disk parameters> [--shrink] [-k] |
where:
| to |
...
| physical |
...
Usage is the following:
$ mtd [options] <tape device name> <tape container name> |
where the options are:
...
Creates an execution log “file name”.
...
Directs to ignore bad blocks and continue processing without interruption. It implies "-r 0"
...
Enable verbose trace of data transfer (implies "-p")
Example:
...
| tapes | /tape1. | vtape
Use the following syntax to write the content of a tape container to a physical tape:
$ mtd <tape container name> <tape device name> |
...
| class | pagebreak |
|---|
...
$ mtd /charon/tapes/tape1.vtape /dev/st5 |
...
The "hasp_srm_view" utility displays content of CHARON-AXP licenses.
Run the utility with one of the following parameters to see the license(-s) details:
- "-l" (or without parameters) - CHARON default license details
- "-all" - all available CHARON licenses details
- "-key <key number>" - specific CHARON license (defined by its "key number") details
The "hasp_srm_view" utility provides the following functionality:
- Display the CHARON-AXP licenses details. It is possible to view all available license or some specific one.
- Collecting license status information
- Collecting host fingerprint information
- Managing software license transfer procedure.
Run the utility without any options to display the license details.
|
The specific type of CHARON license defines what switches may be used in each case.
Collecting the "c2v" file can be done only from the CHARON host console.
Remote collection of status information
For remote collection of status information it is recommended to use "ssh" as shown in the following examples:
# ssh root@CHARON_HOST /opt/charon/bin/hasp_srm_view -c2v /opt/charon/bin/my_hasp_key.c2v# ssh root@CHARON_HOST /opt/charon/bin/hasp_srm_view -fgp /opt/charon/bin/my_host_fingerprint.c2v |
To see the license text on the console:
# ssh root@localhost /opt/charon/bin/hasp_srm_view |
To collect license text to an output file on host server:
# ssh root@localhost /opt/charon/bin/hasp_srm_view > /opt/charon/bin/hasp_srm_view.txt |
The "hasp_srm_view" utility always reports the ID and IP address of the host(s) where active licenses are found.
...
The "hasp_update" is a Sentinel standard utility for license management included in CHARON-AXP kit.
To invoke the "hasp_update" utility login as "root" and use the following syntax:
# hasp_update <option> [filename] |
where:
| Parameter | Value | Description |
|---|---|---|
| <option> | u | Updates a Sentinel protection key / attaches a detached license |
| i | Retrieves Sentinel protection key information | |
| d | Detaches a license from a Sentinel Software License (SL) key | |
| r | Rehost a license from a Sentinel Software License (SL) key | |
| h | Display help | |
| [filename] | Path to the V2C/H2R file when used with the 'u' option | |
Optional path to the C2V file when used with the 'i' option Uses "stdout" if file name is not specified | ||
Example:
|
| Info |
|---|
We recommend to use this tool only for "Update a Sentinel protection key / attach a detached license" function ("u" option). For the rest use "hasp_srm_view" utility. |
...
Used to display the CHARON license contents, to collect the host system fingerprint and to collect license data required for license updates. | |
| hasp_update | Sentinel standard utility. Used with Charon to install and update licenses. |
| ncu | Used to dedicate a host interface to CHARON-AXP, to release it back to the host and to manage CHARON virtual interfaces (TAPs |

Dedication of a host physical interface to CHARON
...
. |
...
Enter "4" then enter the interface name that is a bridge to the Linux virtual network on this host ("eth1" in our example):
|
Enter "6" to quit "ncu" utility.
...
|
The utility lists available network interfaces (both physical and virtual) and indicates whether they are dedicated to the host or to CHARON and whether they are currently in use by host operating system.
"ncu" offers several options:
- Dedicate interface to CHARON
- Release interface to host
- Create a bridge between a chosen physical network interface and the Linux virtual network and create a number of virtual network interfaces
- Remove the Linux virtual network and all the created virtual network interfaces
- Print status - use it to display status of network interfaces and the menu shown above
- Exit
In the example above we see 2 network interfaces - "eth0" and "eth1", both of them are dedicated to host, but host uses only the interface "eth0".
Let's dedicate the interface "eth1" to CHARON-AXP.
Enter "1", then type "eth1" and press Enter:
|
...
| class | pagebreak |
|---|
Now the interface "eth1" is dedicated to CHARON-AXP:
|
Enter "6" to return to console prompt.
Now "eth1" can be used by CHARON-AXP.
Release of a host physical interface back to host
Login as root and enter "ncu". The following menu will appear:
|
Let's say that we want to return the interface "eth1" (currently dedicated to CHARON) back to host. To do that enter "2" then "eth1":
|
Enter "6" to quit the "ncu" utility.
The interface "eth1" is released back to host system now.
Creation of a virtual network
Login as root and enter "ncu":
|
Enter "3" to create a bridge between the host physical network adapter and the LINUX virtual network interfaces (TAP) and specify the physical network interface ("eth1" in our example) and the number of virtual network interfaces to be created (2 in our example):
|
...
| class | pagebreak |
|---|
Now enter "5" to see the created virtual interfaces:
|
In the example above we see 2 virtual network Interfaces "tap0" and "tap1" connected to the created bridge. The physical network interface "eth1" is used for the bridge to the virtual network interfaces.
The interfaces "tap0" and "tap1" are ready to be used in CHARON configurations - they do not need to be additionally dedicated to CHARON.
Enter "6" to quit "ncu" utility.
...
| class | pagebreak |
|---|
Removal of a virtual network
Login a root. Start "ncu" utility:
...
# ncu
