USB flash memory drives are very handy portable storage media.
Also known as Thumbdrives and pen drives, these devices plug
into any computer's USB port and are small enough to fit on
a keychain or in a pocket. These instructions are for users
of SecureCRT 4.1 or later.
To run SecureCRT from a USB drive, you create an installation
for SecureCRT manually. This involves copying SecureCRT to
the flash drive, creating a license key file for your registration
information, and setting up a shortcut to the new installation,
with a few other minor modifications. The following instructions
are generally applicable to removable USB drives. You may
need to make some changes to suit your particular needs and
hardware.
- Copy the SecureCRT installation folder to the USB drive
(C:\Program Files\SecureCRT
by default). The top-level directory of my USB device looks
like this:
11/03/2003 21:27 <DIR>
SecureCRT
11/03/2003 21:27 <DIR> Known
Hosts
11/03/2003 22:04 206
SecureCRT.bat
- Copy your Config folder into the USB device's SecureCRT
folder. The location of the Configuration folder can be found in the Global Options dialog in the General category.
The USB device directory structure should now show a \SecureCRT\Config
folder.
- In Notepad or another text editor, create a text file
named SecureCRT.lic containing your license information,
and place that file in the newly created SecureCRT folder
as well. The format of the SecureCRT.lic file is as follows:
Name=<name from registration letter>
Company=<company name from registration letter>
Serial Number=03-xx-xxxxxx
Key=nnnnnn nnnnnn nnnnnn nnnnnn nnnnnn nnnnnn nnnnnn nnnnnn
Issue Date=nn-nn-nnnn
Features=<features from registration letter>
The Features line should only be included in the SecureCRT.lic file if it is in the registration letter.
- Next you need to set up a desktop shortcut pointing to
SecureCRT.exe or to a batch file. The one you choose depends
on how the flash drive is treated by your version of Windows.
If you know that the removable device is always going to
be assigned the same drive letter, you can just create a
shortcut to the SecureCRT executable with the /F flag (more
on this below). If you don't always know which drive letter
the device will be given, you will need to create a short
batch file (a VBScript would also work) to launch SecureCRT,
since shortcuts can't use relative paths in their target
names.
In either case, the use of the /F flag is critical. Otherwise
SecureCRT will try to create the Config folder in your Application
Data folder, which is not what you want.
To create a simple shortcut, use the /F option, and specify
the path to the Config folder. For instance, if you know
G: will always be the location of your removable device,
you would create a shortcut with the target:
G:\SecureCRT\SecureCRT.EXE
/F G:\SecureCRT\Config
To start SecureCRT using a batch file, first create a text
file that looks like this:
---
@echo off
REM * SecureCRT launcher
REM * Allows relative paths
on my removable device
SET SCRT=.\SecureCRT\SecureCRT.EXE
SET CONF=.\SecureCRT\Config
START %SCRT% /F %CONF%
---
The batch file can be saved either on the flash drive or
on your hard disk. Then create a shortcut that executes
the batch file to start SecureCRT.
- If you use SSH2 for any connections, you need to edit
SSH2.ini in the Config folder to point at the correct location
for the host key database. If you place the database at
the top level of your device, the corresponding line in
SSH2.ini would be:
S:"Host Key Database
Location"=..\..\Known Hosts\
- Finally, if you use public-key authentication with any
of your sessions, you can place your public and private
keys on the device as well. If you use password authentication
this step is unnecessary.
