The example in these instructions creates two new TTY devices to access serial devices on two serial servers: • The first server (at 10.0.0.240) only supports raw TCP access. • The second server (at 10.0.0.250) supports the Telnet with RFC 2217 extensions and requires a user login. TTYredirector software is available from selected manufacturers of serial servers. 1. Unpack and Install: A. If the TTYredirector software is in a .zip file, unzip it to obtain the .bin file. B. Run the distribution file: $ sh ttyredirector_404.bin C. Change to the directory that was created: $ cd ttyredirector_oem-4.0.4 D. su to root. E. Install using the RPM kit if your system supports RPM packaging # rpm -i ttyredirector_oem-4.0.4-1.i386.rpm Install using the shell kit for other systems # sh ttyredirector_oem-4.0.4-install.bin F. If you are running Debian (Ubuntu) or another Linux distribution that does not have the /etc/rc.d/init.d direc- tory, you must use the following commands (as root) to start and stop the TTYredirector daemon: # /usr/local/sbin/ttyredirectord --start and # /usr/local/sbin/ttyredirectord --stop 2. Enter a License Key: Enter the license key with the trconfig command: $ trconfig -licensekey xxxx-xxxx-xxxx-xxxx-xxxx license key AIAA-MAQQ-ACBQ-MIZX-TFJA 3. Add the New TTY Devices: A. Use the trconfig command to create two new TTY devices: $ trconfig -addtty mytty0,mytty1 B. Default settings are in effect for these new TTY devices. They can not be used until they are configured. 4. Configure the First TTY device: A. For mytty0 use the IP address and TCP port number for the first device server: $ trconfig -tty mytty0 -server 10.0.50.100 -port 4660 724-746-5500 | blackbox.com Linux Virtual COM user manual 724-746-5500 | blackbox.com Page 5 Quick Start Guide B. The software does not support username/password authentication. Please do not enable –auth username option. C. The software only supports Telnet protocol and RFC 2217 extensions, so you need to enable it. In the WebUI, you will need to enable Virtual COM also. For mytty0, we will specify additional baud rate and flow control settings for the server to initialize with these settings each time. It is necessary to set the serial settings here for the server to run properly. Sample command: $ trconfig -tty mytty0 -protocol telnet -speed 38400 -inflow rts -outflow cts NOTE: The default command demonstrates how to enable Telnet extension and change baud rate to 38400 and enables hard- ware flow control (RTS/CTS).

  • 07/01/2003 First Responder Guide for Law Enforcement and Corrections
    First Responder Guide for Law Enforcement and Corrections Officers 07/01/2003 Preface The purpose of this guide is to provide some basic guidance in using Knoppix as a “first responder” tool to determine whether a computer should be examined in more detail. Here are some examples of how Knoppix might be used: Law enforcement officers have received information of a crime that may not be enough to support a warrant. They decide to conduct a “knock and talk” with the individual. During the contact they obtain consent to look at the individual’s computer for evidence. Knoppix provides a method of looking at the computer, without altering the evidence. Evidence found using Knoppix can be used as a justification to either seize the computer (where clear contraband is found, such as child porn) or establish probable cause to obtain a search warrant. Corrections personnel (Probation, Parole, and/or Pretrial Services Officers) are responsible for supervising defendants and/or offenders for Courts and/or parole authorities. Frequently, this responsibility requires the ability to monitor an offender’s or defendant’s computer use. Knoppix provides a method to take a quick look at the computer, without altering evidence. Again, evidence found using Knoppix can be used for a violation hearing. Additionally, this evidence can be provided to law enforcement for their use in pursuing new criminal charges, i.e., to establish probable cause for a search warrant. Officers are faced with numerous computers for processing. Imaging all of these computers for forensic processing is a timely process. Knoppix can be a method for quickly determining which computers should be imaged immediately.
