Qnx 4.25 Iso

This manual explains the basic philosophy and operation of QNX 4.25. Installation & Configuration. This guide contains the information you'll need to install, configure, and maintain a QNX system. It describes the system services and provides customization guidelines. Utilities Reference. This reference documents the QNX utilities and server. QNX considers each physical disk on a computer to be a block special file. As a block special file, a disk is viewed by a QNX filesystem as a sequential set of blocks, each 512 bytes in size, regardless of the size and capacities of the disk. Blocks are numbered, beginning with the first block on the disk (block 1).

QNX® 4 Product Suite 2015 Experimental Release Notes#

  • I am new to QNX, none the less have been charged with maintenance on a QNX 4.25 system. One thing I would like to do is create disk images of all the hdd's. Some are in Beckhoffs, some are in Dells. One of the contractors that installed this system, a QNX guru, told me that I could do this with a program called Ghost.
  • This guide introduces you to TCP/IP for QNX. You'll find information on TCP/IP configurations, internet mail, remote printing, and the Network File System (NFS). It also includes sections on the “latest and greatest” TCP/IP utilities, servers, and applications.

USB support lets you install QNX from a USB CDROM and install QNX on a USB flash. Serials cracks keygens. The installation program currently doesn't support preparing a boot floppy for the USB floppy drives.

Known issues#

  • It's possible to mount different USB sticks with specific mountpoints by using the Fsys.umass did and vid arguments, but the documentation doesn't explain how. (Ref# J228998)
    Workaround: You must specify the did and vid in full hexadecinal form (e.g., vid=0x1233, not vid=1233). Preparsing the output of usb is the only way.
    If you're specifying a device and a vendor, you must specify the devno and busno (4 arguments).
    The -N option must be unique for each invocation of Fsys.umass.
  • The purpose of vpim is to convert Latin characters into Japanese characters, so if you put the Input driver into Kana (Japanese phonetic alphabet) mode, none of the vpim option modes have any effect. This is normal behavior, as vpim operates only on Latin character input (Romaji). If you're in Kana mode and you want to use vpim, put the Input driver back into Romaji mode via the Alt-key chord.
  • On some boards, if you use a USB keyboard and a USB mouse in PS/2 legacy mode, the USB mouse might work incorrectly in Photon; it might move erratically and generate right-button clicks. (Ref# 71682)
    Workaround: Add the -R option to the kbd protocol in the command you use to launch the Input manager, or in /etc/config/trap/input.$NODE or /etc/config/bin/input.$NODE.
  • If you upgrade from a previous version of the QNX 4 Product Suite to the QNX 4 Product Suite 2010 version and 'QNX 4.25 OS Patch Level G+' component from 2008 CD was installed it'll block the QNX4 Documentation Patch G' component (you'll see that QNX4 Documentation component has two installed patches and patch G is already installed).
    Workaround: Remove QNX 4 Documentation component (F8) and then Install Documentation component with patch G again.
    Note: If you upgrade from a previous version (2008 or 2009) of the QNX 4 Product Suite to the 2010 version we recommend to remove components 'QNX 4.25 OS Patch Level G+' and 'QNX 4.25 OS Patch 2009' before the update. This components was excluded from the QNX 4 Product Suite 2010. To remove components run phinstall program from 2008 or 2009 product Suit CD.
  • The Fsys.atapi driver supports SATA drives only in legacy IDE mode. (Ref# 56067)
  • Don't run crttrap trap while you're running Photon; if you do, your system might crash, or even get corrupted. (Ref# 72418)
    Workaround: Run crttrap trap only in text mode.
    Note: If your system boots automatically into Photon, you can get to text mode by moving /etc/config/bin/ph.num (where num is your system's node number) to a different location, such as root's home directory, and then rebooting. You can move the file back to its original location later if you wish to boot into Photon again.
  • USB keyboards or USB mice can freeze sometimes if the USB keyboard and USB mouse are used at the same time and Net and io-usb are sharing one interrupt line.
    Workaround: Restart Photon or the Input manager.
  • On several boards, the installation program can hang up on ATAPI detection if the USB stack is enabled (F7 in the Safe Mode menu).
  • The installation program can hang if you try to probe and set video mode during the installation for some unsupported video controllers.
    Workaround: Skip the video mode probe procedure during the installation. (Answer 'No' for the installer question 'Do you want to probe and set video modes now?'). The first time you boot: Comment out the line with Hydra.ms in the file /qnx4/graphics/trappers/crttrap.list.
    Run crttrap trap to probe the video mode.
    Start Photon.
    Note: Unsupported graphics controllers will work in 640x480x16 mode only.
  • If you've installed both the TCPIP 4.25 stack and TCPIP 5.10, and you then remove the currently used version of TCPIP in the Phinstall program, then to set up the links for the remaining TCP/IP, run the /usr/tcprt/switch.tcpip script. You can also use this script to switch between the versions of TCP/IP.
  • The TCPIP 5.10 configuration script updates only the /etc/config/bin/tcpip.$NODE script during the installation and leaves /etc/netstart and /etc/nfsstart unchanged. If you're using the /etc/netstart script to launch TCP/IP 4.25 components, and you then update to TCPIP 5.10, you have to edit the /etc/netstart and /etc/nfsstart scripts manually or replace these files with netstart and nfsstart from the /etc/config/socket directory. This directory contains default configuration files and scripts for the currently used TCP/IP stack.

This chapter covers the following topics:

SNMPv2 is the second version of the Simple NetworkManagement Protocol. SNMP lets you manage multiple networkdevices (agents) from a central location(manager) using a simple common protocolsupported by many different manufacturers.

QNX 4 support for SNMP consists of the following:

  • SNMP C library
  • SNMP agent
  • A set of utilities that can be used to access information from the supplied agent or other agents available to you.

There are five configuration files required to use theseapplications:

These files reside under your /etc directory.For more information, refer to the ``Architecture' and the ``Administrative model' sections belowand to the TCP/IP Utilities chapter.

Here's a brief description of each of the config files:

/etc/acl.conf
Defines what operations the source party will be allowed to perform on the objects defined in the context.
/etc/context.conf
Defines which views shall be available to different source-party/destination-party pairs.
/etc/mib.txt
Contains your MIB database description. You can also specify its location using the environment variable MIBFILE (e.g. export MIBFILE=/etc/mib.txt).
/etc/party.conf
Defines the different parties that will be used to communicate between the agents and managers.
/etc/view.conf
Defines the different collections of object resources that can be presented by the destination party to the source party.

The following programs are available with QNX SNMPv2. For more information, refer to the TCP/IP Utilitieschapter in this guide.

SNMPv2 agent

The snmpd daemon (/usr/ucb/snmpd)is a server that receives and responds to SNMP messages sentto the SNMP port on the local machine.

SNMPv2 utilities

SNMPv2 includes the following utilities:

  • /usr/ucb/snmpbulkwalk
  • /usr/ucb/snmpget
  • /usr/ucb/snmpnetstat
  • /usr/ucb/snmpset
  • /usr/ucb/snmptest
  • /usr/ucb/snmptranslate
  • /usr/ucb/snmptrap
  • /usr/ucb/snmptrapd
  • /usr/ucb/snmpwalk

SNMPv2 C library

There's also an SNMPv2 C lib available to write your ownSNMPv2 applications. For information on writingSNMP apps, please refer to the API Functions (snmp_*())in the TCP/IP Programmer's Guide.

The SNMP MIB (Management Information Base) describes the datathat can be queried or modified via the SNMP protocol. Thisinformation allows agents on a network to be managed. Thisdata includes configuration, performance, faults,accounting, and security. The MIB defines its managedobjects using a structure of management information (SMI).The SMI defines the syntax for the MIB. For an example of anMIB, please see the /etc/mib.txt file. Thisis the MIB used by the QNX SNMP programs.

Objects in the MIB are identified using a unique objectidentifier (OID). The object identifier is made up of asequence of nonnegative integers separated by a dot (forexample: .1.3.6.1). You can also use a textualname to represent each component of the OID (e.g. theequivalent of .1.3.6.1 is .iso.org.dod.internet).

The chain of values is organized into a structure that'ssimilar to a filesystem. In the example above,.1 (iso) is like a directory atthe root of the filesystem.

For example, data that is common to all systems can be foundunder .1.3.6.1.2 (.iso.org.dod.internet.mgmt), while data thatis proprietary for a particular device can be found under.1.3.6.1.4(.iso.org.do.internet.private). To query thesyscontact variable on a SNMP agent you would use the objectidentifier .1.3.6.1.2.1.1.4, which isequivalent to:

The MIB definition (/etc/mib.txt) containsthe names of all the objects that can be queried or modifiedon the system.

In SNMPv1, authentication was done with a cleartext passwordreferred to as the ``community.' A common valuefor this would be ``public.'

SNMPv2 uses a more complex configuration to implement itsauthentication. It replaces the community value with aconcept involving contexts, parties,and views.

The authentication is configured with four files found inthe /etc directory:

  • /etc/acl.conf
  • /etc/context.conf
  • /etc/party.conf
  • /etc/view.conf

Each file contains a brief description telling you how toconfigure it; you should also see the reference describingeach file in the TCP/IP Utilities chapter in this guide.

Here are the different components of this authentication concept:

Party (/etc/party.conf)

The SNMPv2 party is a conceptual, virtualexecution environment. When an agent or manager performs anaction, it does so as a defined party, using the party'senvironment as described in the configuration files.

By using the party concept, an agent can permit one managerto do a certain set of operations, and another manager to doa different set of operations. Each communication sessionwith a different manager can have its own environment. Hereare two entries from a party config file(/etc/party.conf) for an agent and amanager.

The agent and manager definition use the same format. Itstarts with the name of the party (agent_partyand manager_party) and follows with the uniqueparty identity value. This value starts with:

which resolves to:

in the MIB. (Please refer to the /etc/mib.txt file for moreinformation on the ``InitialPartyID' value.)

The next line of values are the transport domain, the IPaddress that the party exists on, and a port to listen to.The manager_party just specifies 0.0.0.0 0 tosignify that it's a remote machine. The agent_partyentry specifies 10.0.0.59 161 which is the IP address ofone of its interfaces and a port to listen to. These two exampleparties will communicate with no authentication(noAuth) and no privacy (noPriv)and are listed as the fifth and sixth parties defined under``InitialPartyID.'

View (/etc/view.conf)

The /etc/view.conf file containsview configurations. Each view definition is alist of objects that are are part of the view. You caninclude or exclude objects from the view. When a partyattempts to access the agent MIB, they will see only theobjects contained in the view.

This creates a view number 3, which includes all of the objects under theMIB subtree .iso.org.dod.internet.mgmt.

Context (/etc/context.conf)

The context.conf file contains thedefinitions made up of a collection of object resourcesaccessible by a network entity.

The context definition starts with the name of the context(in this case agent_context) and is followedby the unique object identifier that represents thiscontext. It starts with the value:

which resolves to:

For more information on the initialContextID,please refer to the /etc/mib.txt file. Thisagent_context will represent the collection ofobject resources that the manager will be able to access.You can define different contexts for differentagent/manager pairs. This is demonstrated in theacl.conf file.

Access control list (acl.conf)

The access control list is where you define what contextwill be available to an agent and manager. You can alsodefine what operations will be permitted on the collectionof object resources.

In this example, the manager can perform operations on theobjects defined in agent_context. Theseoperations are limited to the following:

B
GetBulk
G
Get
N
GetNext
S
Set
U
SNMPv2-Trap

The other operations that can be specified are:

I
Inform
R
Response

Now that we have all the files(/etc/party.conf,/etc/view.conf,/etc/context.conf, and/etc/acl.conf) configured, we can access somedata on the server.

Let's now take a look at a few examples of using the agentand utilities. Please refer to the TCP/IP Utilities chapterin this guide for more information on the optionsthat can be passed to the agent and utilities mentionedhere.

These examples assume that the configuration files andmib.txt are located in the/etc directory and that the utilities are inthe /usr/ucb directory.

The first thing we need is an agent to query. For thisexample, we'll use the agent supplied with your software:

If you run into any problems with the agent, you could tryspecifying the -d option, which dumps all sentand received packets to the screen. This option is availableto several of the utilities also.

Qnx 4.25 Iso

Once the SNMPv2 agent is running, we could use thesnmpget utility to query an object resource:

The output would look something like this:

Qnx 4.25 Iso Download

Using the snmpset command, we can change thestring value of sysContact:

The output would look something like this:

Now when someone uses an SNMP utility to querysystem.syscontact, the string value ``Not me' will be returned.

Let's now take a look at the snmptrap andsnmptrapd utilities. The first thing we'll wantto do is start the snmptrapd utility. It willreceive the trap PDU messages from snmptrap.

The -p option tells snmptrapd to printlog information regarding trap messages received to thescreen. We can now use snmptrap to send a trapmessage.

The snmptrapd server would log a message something like this:
