I believe this topic came up before but I didn't pay attention to the response/solution because I didn't realize I had the same problem until recently. I am running news 2.11 B patch level #14. I assumed that any cross posted articles were being symbolically linked to one primary article. This is not the case. Identical copies of the same article are being produced. Does anyone have a solution to this problem? I am running ULTRIX 2.0 on a MicroVAX II.

Netnews uses UNIX "hard" links to link the multiple instantiations of a news article into the multiple newsgroup directories. Netnews is most certainly NOT making N copies of an article for appearance in N newsgroups, except on VMS systems, under Eunice (but then, they deserve to lose). I suggest that you go back and read up on the UNIX filesystem structure, paying particular attention to the concept of "inodes" and "directories." A "hard" link is simply another directory entry that refers to the same inode; no extra disk space required, modulo that required by the directory entry. Erik E.

I did the Eunice code for 2.11 news, and it makes the equivalent of symbolic links. The article is stored under the first newsgroup, and the remaining newsgroups have a tiny file containing nothing but the name of the first file (I stole this from Larry Wall's Eunice code in "rn"). -- - Joe Buck {uunet,ucbvax,sun,<smart-site>}!epimass.epi.com!jbuck Old Internet mailers: jbuck%epimass.epi.com@uunet.uu.net

Fair ucbvax!fair fair@ucbarpa.berkeley.edu There was an interesting mis-feature in VMS prior to version 3.0 which allowed (and may still allow) creating something like hard links by judicious use of COPY/OVERLAY and a few other simple commands to create a fake directory (which was then copied onto the real directory). Has this been fixed? Has anyone found anything useful to do with it? Did you even know this bug existed? - John. -- John F. Haugh II SNAIL: HECI Exploration Co. Inc.
