Greetings...
I've just installed C News (24-MAR-1991) and NNTP (1.5.11) under
Ultrix 4.1. Things work just fine except articles posted locally have
the local host twice in their Path: field:
Path: newshub.ccs.yorku.ca!newshub.ccs.yorku.ca!mike
Can this cause problems? If someone could point me to documentation
or explain how to fix this I'd greatly appreciate it.
(I saw nothing in the documentation about this.)
Thanks...
Mike

The C News posting machinery is respecting the existing path and just adding the local name on the front. The fix is to fix the posting software. This just might be NNTP's fault if you are posting through it, but whatever you're using as reader/poster is more likely to be at fault. It's relatively harmless. -- And the bean-counter replied, | Henry Spencer @ U of Toronto Zoology "beans are more important". | henry@zoo.toronto.edu utzoo!henry

You are correct in thinking that our postnews does not try to be clever. -- And the bean-counter replied, | Henry Spencer @ U of Toronto Zoology "beans are more important". | henry@zoo.toronto.edu utzoo!henry

That's what I thought at first so I tried the postnews supplied (but unsupported I realize :-) ) with C-news but this happens as well. As far as I can tell postnews does not produce a path header and just passes the stuff to inews. This means that I probably managed to mangle something in C-news itself. I'll have to trace it sometime soon whan I have the time.

The "stupidity", if any, is most likely not a mistake, but an attempt (futile, I know), to make the Path: header usable for mail replies - when posting over NNTP, the poster need not even have an account on the server host, and so the posting program provides a 'Path: posting-host!user' line. Perhaps the posting program should detect that posting-host is equal to nntpserver, and skip the Path: in this case, but I don't know of any that does. >The fix is to fix the posting software. This just might be NNTP's fault >if you are posting through it, but whatever you're using as reader/poster >is more likely to be at fault. Nntpd just passes the bytes to inews; the mini-inews that comes with the NNTP distribution does create a Path: header in certain circumstances, though. >It's relatively harmless. Agreed, but it's ugly and space-wasting - and easily fixable in C news, of course - the fix (to relay/hdrmunge.c) that isn't one is appended below, but somehow I don't expect it to show up in the official patches:-). --Per Hedeland per@erix.ericsson.se or per%erix.ericsson.se@uunet.uu.net or ...uunet!erix.ericsson.se!per *** /tmp/,RCSt1a03848 Thu May 16 23:32:31 1991 --- hdrmunge.c Sun Apr 28 12:04:49 1991 *************** *** 177,205 **** { if (CISTREQN(hdr, pathhdr.hdrnm, (int)pathhdr.hdrlen)) { register char *oldpath, *hostnm = hostname(); oldpath = skipsp(&hdr[pathhdr.hdrlen]); - /* - * V7 f?printf return 0 or EOF, not a byte count, so it is - * not portable to use fprintf's return value as a byte count. - */ - if (fprintf(art->a_artf, "%s %s!", pathhdr.hdrnm, hostnm) == - EOF || fputs(oldpath, art->a_artf) == EOF) - fulldisk(art, spoolnm(art)); - else { - static unsigned hostlen = 0; ! if (hostlen == 0) ! hostlen = strlen(hostnm); ! art->a_charswritten += pathhdr.hdrlen + STRLEN(" ") + ! hostlen + STRLEN("!") + strlen(oldpath); } - } else { - if (fwrite(hdr, hdrlen, 1, art->a_artf) != 1) - fulldisk(art, spoolnm(art)); - else - art->a_charswritten += hdrlen; } } /* --- 187,224 ---- { if (CISTREQN(hdr, pathhdr.hdrnm, (int)pathhdr.hdrlen)) { register char *oldpath, *hostnm = hostname(); + static unsigned hostlen = 0; + if (hostlen == 0) + hostlen = strlen(hostnm); oldpath = skipsp(&hdr[pathhdr.hdrlen]); ! /* Don't add our name to Path: if it's already there !

Don't quote me on this, but f you put newshub.ccs.yorku.ca in for both the machine and domain name, you may get the problem you describe. I'd check the /usr/lib/news/whoami file to see if there's something strange in there, as well as anything else that could have the machine or user name in it.
