References to startup files (/etc/rc*, /etc/tcp, etc.) should be read as /etc/config/sysinit.<node> or /etc/netstart.<node>.
This appendix covers the following topics:
The following programs mentioned in TCP/IP Network Administration aren't currently supported:
| Page in TCP/IP book: | Name of program: |
|---|---|
| 59-60, 245-249 | NIS service or ``yellow pages'' |
| 72 | RARP |
| 94 | whois |
| 119 | fingerd |
| 125 | dmesg |
| 156 | dip, diplogin (Please refer to the Serial Network Configuration chapter for information on how to initiate a remote dial-up serial connection.) |
| 189, etc. | gated (Unsupported version is available on QUICS.) |
| 228 | lockd, share, or statd |
| 236 | automount, automountd |
| 324 | dig, tcpdump, snoop |
| 381-384 | ssh |
| 389-393 | COPS, SATAN |
| 393 | tcpd |
| 413 | archie |
The following table describes functional differences between the QNX implementation of TCP/IP and the one described in TCP/IP Network Administration.
| Page in TCP/IP book: | Difference: |
|---|---|
| xiii | References are made to BSD-based UNIX system. QNX TCP/IP is a BSD-based (4.3) implementation. At the time of publishing, QNX uses BIND 8.1.29 and sendmail 8.8.8.1. |
| 8 | Support isn't available for X.25. |
| 51, 59-60, 130, 245-250, 297 | NIS (Sun's Network Information Service) isn't supported. References to hosts.txt, networks.txt, gettable, and htable don't apply. |
| 90 | Specification of broadcast address in BSD 4.2 vs BSD 4.3. It's implied here that BSD 4.2 doesn't support an ``all ones'' broadcast. QNX supports both. |
| 105-118 | BSD Kernel Configuration doesn't apply to QNX.
BSD TCP/IP system parameters: Packet forwarding can be enabled with a command-line option to Socket (-dforward). |
| 114 | The UDP checksum is always enabled. |
| 124 | QNX Ethernet network interface names have the format enx where x is the logical network number. This name is referred to as le0 on a Sun OS system. |
| 130 | QNX TCP/IP doesn't support the use of the /etc/inet/netmasks configuration file, which lets ifconfig configure its network mask. In QNX, netmasks must be configured via the ifconfig command line. |
| 153-158 | Refer to references in this guide for appropriate use of slattach. Procedures documented in TCP/IP Network Administration don't apply to the QNX implementation of slattach. Also, sldetach isn't available. |
| 221 | named logs output messages to syslog(). |
| 230-235 | The QNX implementation of mountd doesn't support exportfs and doesn't use /etc/xtab (it uses /etc/exports directly). |
| 275 | The QNX implementation of sendmail doesn't support the creation of a dbm database; but QNX does support the ``new Berkeley DB.'' |
| 276-281 | Sample sendmail configuration prototype files aren't included with this release. Ignore references to m4 as support isn't shipped with QNX. |
| 369-377 | Utilities mentioned in the password section aren't shipped with QNX. The QNX Installation & Configuration manual should be referred to for information about passwords. |
| 532-582 | The QNX sendmail queue directory is in /usr/spool/queue, not /var/spool/mqueue as stated. This is a configurable parameter in /etc/sendmail.cf. |
| 532-582 | All sendmail configuration files are located in the /etc directory. The sendmail program itself is found in /usr/ucb. |

References to startup files (/etc/rc*, /etc/tcp, etc.) should be read as /etc/config/sysinit.<node> or /etc/netstart.<node>. |
