This allows a VMS system to participate in the world wide Internet network and take advantage of the wealth of information and software available on it. Support for various network interfaces is given in this table: +---------------------------------------------------------------------+ I Network Interface SUPPORTED ? I +---------------------------------------------------------------------+ I I I IP over Ethernet YES I I IP over Serial Line (SLIP) YES [1] I I IP over DECnet YES I I IP over Compressed SLIP YES, via 3rd party driver I I IP over X25 YES, via 3rd party driver I I I I IP over Serial Line (PPP) NO I I I +---------------------------------------------------------------------+ [1] SLIP is supported for statically connected links only; there is no dial-out support, and dial-in is supported only partially. Support for various standard TCP services is given in this table: +---------------------------------------------------------------------+ I Application Client Server I +---------------------------------------------------------------------+ I I I TELNET YES YES I I FTP [1] YES YES I I LPD YES YES I I FINGER YES YES I I TALK YES YES I I X windows YES YES I I MAIL [2] YES (3rd party s'ware) YES (3rd party s'ware) I I NFS [3] NO NO (broke with 6.6-5) I I RLOGIN [4] YES (3rd party s'ware) YES (3rd party s'ware) I I REXEC NO NO I I RSH [4] YES (3'rd party s'ware YES (3rd party s'ware) I I XDM -- NO I I I +---------------------------------------------------------------------+ [1] Although FTP is included with OpenCMU, a much improved client and server is available as freeware - MadGoat FTP. See the applications section later. [2] MAIL is supported through the freeware MX package. See the applications section later. [3] An NFS server was supported up to Version 6.6-4. It broke with Version 6.6-5. [4] RLOGIN/RSH client/server is available through a third party; see the applications section later. Also Available: o IPNCP for monitoring and controlling the TCP/IP system o UNIXSHR - A TCP/IP socket library Also Supported: o Domain Name Service is supported through the freeware DOMAIN package by Bruce Orchard. Usually available from the same sites as OpenCMU. Note: o Electronic mail support is also provided by the chargeable PMDF package available from Innosoft. Contact them for details. -------------------------------------------------------------------------------- 1.2 >>>> OBTAINING THE OPENCMU SOFTWARE [30-MAR-1995] --------------------------------------- The OpenCMU software is entirely free of charge and may be obtained through your local DECUS representative. The last relevant symposium tape that contains the OpenCMU software is the Fall 1992 tape, in directory [VAX92B.CMU] and on DECUS CDROM #12. A number of sites on the Internet maintain up to date anonymous FTP directories containing the OpenCMU software. These can be accessed using the FTP program or a mail server such as FTPMAIL that can transfer files from an anonymous FTP account back to the requestor via e-mail. The following URLs point to where the latest versions of software may be obtained: * Master Site: ftp://sacusr.mp.usbr.gov/cmuip/ (Henry Miller ) ftp://sacusr.mp.usbr.gov/tekip/ftp/ ( " ) ftp://sacusr.mp.usbr.gov/telnet/ ( " ) * Mirrors ftp://ftp2.kcl.ac.uk/vms/cmu-tcpip/ (Andy Harper ) ftp://ftp.csus.edu/pub/cmuip/ ( ?? ) ftp://dmc.com/vms/cmuip/ (Dick Munroe ) ftp://marduk.iib.uam.es/pub/VMS/cmutek-ip/ (J.R.Valverde ) There are versions of OpenCMU available that run on earlier versions of VMS available from a number of sources: DECUS Fall 92 tape, directory [VAX92B.CMU] DECUS CDROM VS0152, directory [LT92B.CMU] ftp://flash.acornsw.com, directory VS0152:[LT92B.CMU] ftp://ftp2.kcl.ac.uk/vms/cmu-tcpip/oldversion/ The first time you obtain OpenCMU, you will very likely not have an existing network facility and hence will be unable to obtain the software across the network. In this case, you should contact your local DECUS representative for a copy of the software on a suitable media. Subsequently, you can pick up new versions and patches using the network from many of the sites listed above. Announcements about these are made to the OpenCMU mailing list. -------------------------------------------------------------------------------- 1.3 >>>> PREREQUISITES [30-MAR-1995] ---------------------- Before installing OpenCMU on your system, take note of the following requirements. Hardware Requirements: A Digital VAX system. NOTE: Digital ALPHA systems are NOT currently supported. A Network interface. OpenCMU supports the following types of network interface: * Ethernet * Serial line (using SLIP) * X.25 Synchronous interface * DECnet link A network link to the outside world. The network interface must be connected to a network with at least one other network aware system connected to it. Consult your local site management or network service providers for details of how to connect to the rest of the IP world (the `Internet'). Each interface to the network MUST be allocated its own unique IP address (your service provider will supply this) and a subnet mask. Although optional, it is highly likely that access to an IP router and a Domain Name Server will be required. Ask your service provider for the IP addresses of each of these. Minimum VMS: The latest version of OpenCMU requires VMS 5.2 and upwards. -------------------------------------------------------------------------------- 1.4 >>>> HOW DOES OPENCMU AFFECT DECNET? [12-SEP-1995] ---------------------------------------- The short answer - it doesn't. OpenCMU and DECnet are completely independent. You can run either by itself or both together. The same applies to LAT, X25 over LLC2, PathWorks and all the other network protocols supported by OpenVMS. The only thing necessary is to start DECnet first if both are used. This is because DECnet needs to modify the ethernet address and hence be the only user of the network while it does that. -------------------------------------------------------------------------------- 1.5 >>>> CURRENT VERSIONS OF OPENCMU [31-MAR-1995] ------------------------------------ Base Version: OpenCMU 6.6-5 Kit: CMUIP066.% { % = A,B,C,D } Update Kits: OpenCMU 6.6-5A Kit: TEKIP0665A.SAVE Telnet 5.0-1 Kit: TELNETU1050.A FTP 2.12 Kit: FTPU0212.A VMS Version Specific Update Kits: Drivers for OpenVMS 6.x Kit: V6DRIVER.SAVE FTP_SERVER for VMS 6.x Kit: FTP_SERVER.SAVE IPACP for OpenVMS 6.1 Kit: IPACP.EXE Additional Kits: Compressed Slip driver CSDRV.BCK X25 driver X25DRV.BCK Domain name service kit DOMAIN-%.BCK (% = A,B,C) -------------------------------------------------------------------------------- 1.6 >>>> THE OPENCMU MAILING LIST/NEWSGROUP [11-OCT-1994] ------------------------------------------- An electronic mailing list and news group exists for exchanging information about the OpenCMU software. This is the preferred way to exchange information about problems, and their solutions, and to announce updates to the software. By subscribing, you gain access to a wealth of practical information from other users and the relevant OpenCMU experts. The address of the electronic mailing list, to which all enquiries or announcements are directed, is: CMU-OpenVMS-IP@sacto.mp.usbr.gov Subscribe by sending a message containing the single line `subscribe' to: CMU-OpenVMS-IP-Request@sacto.mp.usbr.gov For those with access to USENET, the world-wide electronic NEWS system, this mailing list is automatically gatewayed to the newsgroup: vmsnet.networks.tcp-ip.cmu-tek You are recommended to subscribe to the newsgroup wherever possible, in preference to the electronic mailing list. Details of some suitable news readers can be found elsewhere in this document. NOTE - Archives of the mailing list can be found under: ftp://sacto.mp.usbr.gov/pub/archive/CMU-OpenVMS-IP/ -------------------------------------------------------------------------------- 1.7 >>>> GETTING TECHNICAL HELP FROM THE NEWSGROUP [28-MAR-1995] -------------------------------------------------- Much of the information flow on the OpenCMU mailing list and newsgroup are questions such as `I can't make OpenCMU work...' or some derivative thereof. There are two fast ways you can get information that may help to solve your problem and it's worth trying these before trying the newsgroup: o Look in the manual. There is extensive info in the manual about most aspects of the OpenCMU package. o Look in the FAQ. Some things that aren't documented in the manual are in the FAQ. Your question may be a common one and, if so, the answer could well be there. It is also useful to: o Check the configuration. Most problems arise through a failure to correctly configure some aspect of the OpenCMU software; often because of a misunderstanding of the various items involved. o Check system/user quotas and system parameters. The software is sensitive to quotas and some system parameters. The manual and the FAQ both contain information on the key ones. Don't assume that the `out of the box' software' will run on your system without some tuning. If you have checked everything above, and still feel the need to get advice from other users, make sure that you give sufficient information to convey the problem to others by enclosing these details: A. A description of the problem; Be as specific as possible, since vague statements are not helpful. B. Details of your configuration. Here, it's probably best to enclose a copy of the various configuration files IN THEIR ENTIRETY (I.E. don't edit them to include only the relevant bits because you don't necessarily know what the relevant bits are yet). Files to include are: INTERNET.CONFIG NAMRES.CONFIG IP_STARTUP.COM C. A sample transcript of the session, if possible, which includes all the error messages. Enclose the whole transcript, not just the portion that shows the error. Something that happened earlier might just affect what you're doing. A transcript can be created in a number of ways, perhaps the easiest is to use the "SET HOST 0/LOG" command. This creates a new session (and you need to login again), recording everything that appears on your terminal in a file called "SETHOST.LOG". This logfile is closed once you logoff the new session.
