Vxworks License Server
Glauco Schlembach
I'm having trouble debugging a WindRiver build system where the build machine seems unable to obtain a license from the WindRiver license server. Is there a tool that allows me to run a "get me a license" check without having to run a complete build?
Paul, in this case, if you're using another machine as a license server, first be sure that the server is up and running, after that on the client machine, set the environment variable WRSD_LICENSE_FILE = 27000@ and test.
> > > LOCAL_ECHO offTry turning this on - I seem to remember when playing with a demo
server we used as an example in VxWorks AE that MS telnet wouldn't
play ball unless the local echo was enabled.Note to earlier poster who said that telnet clients are all alike:
they are not, and the MS one has a number of differences. My simple
telnet server demo application worked perfectly with all unix clients
we tried, but I had to change several settings in the MS one to make
it work on Windoze.I didn't try PuTTY at that point partly because I hadn't discovered
it, and partly because the requirement was to work with MS telnet, so
I don't know if it would work out of the box with VxWorks - I do know
that it works much better when connecting to Unix servers than the MS
one, and it supports rsh/rlogin and ssh into the bargain.Back to the problem... you could also try typing the following to see
what happens:reboot^J(where ^J is control key + J)If the target reboots, then this could be part of the problem too:
You probably want to send just LF rather than both. VxWorks is
unix-like in this respect, and I'm not sure whether the shell
interpreter will cope with the CR characters at the end of every line;
if I had to guess, I'd say it wouldn't.> > > WILL TERM TYPEThis might also be a good thing to disable as I don't expect the
VxWorks end will respond to it - might be wrong on that, and I don't
have a target any more I can try it with. If you can disable the
automatic term type determination, and just force it to a vt100 like
setting, that'll probably be the safest option.
Have you checked the status of the network connection? You can use
netstat on Windoze from a command prompt to see the active connections
on that end, and if you add the network show routines to VxWorks,
inetstatShow will give a similar thing there (you'll need to use a
WindSh session of course ;-)HTH,
John...
I know (or think I know...) the router works ok, as routing to my
development host with Telnet server enabled works fine.I don't have access to a remote machine with tcpdump...Randy Ryan

Do you have a default route set on the target system? If not, try
setting one with routeAdd "0", "Gateway IP address" (you can add this
to the end of the init sequence on the target so that it will always
be there when you boot the target).

The SSH server (IPSSH) implementation in VxWorks 6.5 through 6.9 contains a denial-of-service (DoS) vulnerability due to an issue in processing authentication requests. An attacker could send specially crafted authentication requests to cause an SSH server outage. SSH access may become unavailable until the next reboot as a result of this vulnerability being exploited.
The SSH server (IPSSH) implementation in VxWorks 6.5 through 6.9 contains a DoS vulnerability due to an issue in processing pty requests. Receiving a specially crafted pty request packet may cause SSH access to be unavailable until the next reboot. The attacker must login with a valid user name and password combination before launching a successful attack.
The SSH server (IPSSH) implementation in VxWorks 6.5 through 6.9 contains vulnerability due to an issue in the processing authentication requests. Receiving a specially crafted packet for a public key authentication request may cause the server to hang and SSH access to be unavailable until the next reboot. In addition, arbitrary code may be executed on the server with administrator privileges.
The WebCLI component in VxWorks 5.5 through 6.9 contains a DoS vulnerability due to an issue in parsing command strings. An attacker can login to a CLI session and cause the current CLI session to terminate. A new CLI session may be re-established without rebooting.
According to Wind River, software patches for these vulnerabilities are available for all affected VxWorks versions. Users interested in obtaining these patches should contact Wind River technical support for assistance.
NCCIC also provides a section for control systems security recommended practices on the ICS-CERT web page. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
Additional mitigation guidance and recommended practices are publicly available on the ICS-CERT website in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.
One customer started playing around with VxWorks 7 SDK for QEMU (sabrelite). Then he built a custom VSB and VIP project for imx6 sabrelite QEMU. He is trying to access a FTP server on the host machine from the QEMU VxWorks image, in the same way he did it with the WindRiver Lab image he used for his initial testings.
We recommend getting familiar with some of the concepts and tools that you will be using in this tutorial. We will be covering: interacting with the Transaction File Server (TFS), inserting a row with the function call rdm_dbInsertRow(), and reading rows with the function call rdm_cursorReadRow(). You may also find it useful to read about the DOCROOT as well.
Your program should be fully functional at this point. You set up a Remote TFS which is used when you are interacting with a database through server processes, and you wrote and read rows from the database by interacting with the TFS.
With an SMB software stack, embedded systems running VxWorks can securely and efficiently share resources and files with a wide variety of network endpoints including Windows, Linux, macOS, and iOS devices.
While VxWorks can use protocols like FTP (File Transfer Protocol) and SFTP ( Secure File Transfer Protocol) can also enable file transfers, SMB provides more robust and efficient resource sharing. Because SMB is natively supported on Windows and macOS, the integration of VxWorks systems into heterogeneous is simpler than with other file transfer protocols. A VxWorks device running an SMB stack can communicate with Windows and macOS systems without users installing any additional software. With FTP/SFTP, users must install client or server software on each endpoint. The YNQ Client on a VxWorks device can operate as file system driver (a plug and play solution) or as an application on the VxWorks RTOS.

This document illustrates the methods used to upgrade an Access Point (AP) that runs VxWorks firmware through a console connection. This method is useful when the user does not have an FTP server or the AP is not configured with an IP address where a browser can connect. Refer to the Updating Firmware section of Managing Firmware and Configurations for directions on how to perform a firmware upgrade through a web browser or from a file server.
The information in this document is based on VxWorks firmware version 12.01T1 upgraded to the VxWorks firmware version 12.05. This upgrade procedure uses a 1200 AP that runs VxWorks firmware image 12.01T1.
A straight-through nine-pin serial extension cable is required to connect the COM1 or COM2 port on the computer to the console port on the AP. After the cable is connected, use a terminal emulator (such as Hyper Terminal) and set the session with these settings:
