1.2 What are the OpenVMS Usenet Newsgroups?



¼There are a huge number of newsgroups available, some of which discuss topics of interest to folks using OpenVMS operating system. Key among these are the comp.os.vms 3newsgroup and the vmsnet.* heirarchy of newsgroups.S

1.2.1 What is the scope of the comp.os.vms newsgroup?



"The comp.os.vms —newsgroup is the primary newsgroup for discussion of the HP OpenVMS operating system and the computer systems on which it runs. Questions about layered products which run on OpenVMS are also welcome, though many of them (in particular, language compilers and database systems) have more specific newsgroups. If a question has some relationship to OpenVMS, it belongs in comp.os.vms. R

1.2.2 What newsgroups carry VMS-related information?



@The vmsnet.* hierarchy is operated by the Encompass users group H(formerly known as DECUS), and contains various newsgroups of interest, 'including vmsnet.misc and vmsnet.alpha.

FSprechen Sie Deutsch? Besuchen Sie bitte den newsgroup de.comp.os.vms.

HThe comp.sys.dec newsgroup carries general discussions about various HP Gcomputer systems, and specifically systems that were acquired by HP as Epart of the acquisition of Compaq, systems which had previously been Cacquired by Compaq as part of the acquisition of Digital Equipment Corporation (DIGITAL).

BAlso of interest are resources and conferencing systems including FEncompasserve (formerly known as DECUServe), Ken Farmer's OpenVMS.Org forums,#and the Compaq Working Group folks:

1.2.3 What newsgroup archives are available?



'Extensive archives of INFO-VAX mailings"and comp.os.vms &postings are archived and available at/ SRI: #ftp://crvax.sri.com/info-vax/ 

Google3 also has extensive newsgroup archives available at

F

1.2.4 What is the INFO-VAX mailing list?



cINFO-VAX is a mailing list which is bidirectionally gatewayed to the comp.os.vms Fnewsgroup. This means that postings to comp.os.vms ‘get automatically sent to INFO-VAX subscribers and messages sent to the INFO-VAX list are automatically posted to comp.os.vms. DINFO-VAX can be a useful way to participate in the newsgroup if you Dcan't access the newsgroup directly through a newsreader. Note that EINFO-VAX is a closed mailing list, which means that only subscribers fmay post to it. Please see Section 1.2.4.1 for information on how to Asubscribe, and how you can subscribe such that you can post from Bmultiple addresses but still receive no more than one copy of the mailings.

FPlease remember that propogation delays can and do vary, meaning that Hmailings and postings may be delayed or even lost. It is quite possible Cthat postings may not be delivered for several days, and that some /postings will appear out of the expected order.

aFor details on the available archives, please see Section 1.2.3.Y

1.2.4.1 How do I subscribe to or unsubscribe from INFO-VAX?



)The address for subscription requests is DInfo-VAX-Request[at]Mvb.Saic.Com. Subscription requests are handled Eautomatically by a mail server. This mail server ignores the subject 9line and processes each line of the message as a command.

AThe syntax for subscribing and unsubscribing, as well as setting ,various parameters on your subscription, is:

 

"
1SUBSCRIBE INFO-VAX      (ADD is a valid synonym) HUNSUBSCRIBE INFO-VAX (REMOVE, SIGNOFF, and SIGN-OFF are valid synonyms) 6SET INFO-VAX DIGEST     (to receive in Digest format) ?SET INFO-VAX NODIGEST   (to receive each message individually) DSET INFO-VAX NOMAIL     (to establish an email address for posting, 7                          though not receiving, mail.) HSET INFO-VAX MAIL       (to establish an email address for both posting /                          and receiving mail.) 




GThe mail server is not case-sensitive; case is irrelevant. Attempts to =fetch copies of the mailing list are rejected for reasons of Fconfidentiality. Any message not understood by the mailserver will be returned entirely unprocessed.

FThe INFO-VAX moderator can be contacted directly at the email address Mark.Berryman[at]Mvb.Saic.Com.

HIf you are on Bitnet, send a mail message containing the text SUBSCRIBE DINFO-VAX to LISTSERVE[at][nearest-Listserv-system). To unsubscribe, @send a message containing the text SIGNOFF INFO-VAX to the same Listserv system.

DIf you are on the Internet in the UK, send a message containing the Gword SUBSCRIBE or UNSUBSCRIBE to info-vax-request[at]ncdlab.ulcc.ac.uk.Q

1.3 What is [n]etiquette?



FBefore posting or emailing a question, please use the available local Hresources, such as the OpenVMS manuals, the HELP, and the resources and Hinformation in and referenced by this FAQ. Please use these first. Also Dplease specifically read the release notes and (if appropriate) the Ccover letter for the product you are using. (The release notes are Egenerally placed in SYS$HELP:.) Quite often, these simple steps will Eallow you to quickly find the answer to your own question---and more Gquickly than waiting for a response to question posted to a newsgroup, Htoo. These steps will save you time, and will also help ensure you have Fa good reputation with the folks that might be included to answer one Eof your future questions, a question not covered in these resources. HPut another way, if you do not want your questions to be ignored in the Afuture---and please remember that the folks in the newsgroups do ?not have to answer your questions---you won't want to D"annoy the natives" by asking a question that has already Ebeen answered far more times more than you might have realized, or a Gquestion whose answer is readily available had you made a small effort.

8When posting, please consider the following suggestions:



BBefore posting your question to the comp.os.vms 1newsgroup or sending your message to the INFO-VAX? list, also please take the time to review available etiquette ? information, such as that included in the following documents:



GThis information will document the etiquette of newsgroups, as well as Fproviding you with the knowledge the vast amount of newsgroup-related Einformation that is readily available to you, and where to find it...



/  
Note

=Please do not post security holes or system crashers

ERather, please report these problems directly to HP. Why? So that HP Chas a chance to resolve and distribute a fix before other customer sites can be affected.

BMost folks in the newsgroups are honest and deserve to know about ?potential security problems, but a few folks can and will make Cnefarious use of this same information. Other sites will hopefully =return the courtesy, and will not post information that will Gpotentially compromise your site and your computer environment.
