I've been noticing a lot of duplicate articles in the group comp.sys.next. (Actually I've noticed them in other groups too, but no where near the extent found in comp.sys.next.) Often in the past when I've noticed this, I've found that the two articles had different article IDs (most often a different number indicating that the author probably resent the article, but sometimes the system name changed from foo.UUCP to foo.foo-domain). Here I have a much more interesting header: Article 729 of comp.sys.next: Path: ucla-cs!sm.unisys.com!cs.utexas.edu!tut.cis.ohio-state.edu!husc6 !uwvax!tank!nic.MR.NET!shamash!nis!ems!amdahl!uunet!csdev!ll1a !spl1!laidbak!att!rutgers!tut.cis.ohio-state.edu!accelerator !baloo.eng.ohio-state.edu!abali From: abali@baloo.eng.ohio-state.edu (Bulent Abali) Newsgroups: comp.sys.next Subject: Re: NeXT Memory - No Error Checking or Message-ID: <8548@spl1.UUCP> Date: 2 Nov 88 17:54:23 GMT References: <549@gt-eedsp.UUCP> <207400001@inmet> Sender: news@spl1.UUCP Reply-To: abali@baloo.eng.ohio-state.edu (Bulent Abali) Organization: Ohio State Univ, College of Engineering Lines: 20 Note that tut.cis.ohio-state.edu shows up twice. There are several other messages with this loop, and many of the other duplicate messages also have tut in their path. Could it be that tut's inews is broken? If not tut, maybe someone else? Note that this is *NOT* an attack on tut's administrators, Ohio State, etc., etc. I know that software breaks. This is just a note of the problem. I've sent a separate copy of this to postmaster@tut.cis.ohio-state.edu, but am also posting it just in case it's some other site. Casey

Thanx to Casey for pointing out this problem to us. As near as I can see, however, the problem is not with us, but with a system called `spl1' elsewhere. I found a couple of sample duplicated articles in comp.sys.next and diff'd the originals against the weird-looking duplicates. Take a look at this: [86] [8:40am] tut:/usr/spool/news/comp/sys/next> diff 583 705 1c1 < Path: tut.cis.ohio-state.edu!accelerator!baloo.eng.ohio-state.edu!abali --- > Path: tut.cis.ohio-state.edu!husc6!uwvax!tank!nic.MR.NET!shamash!nis!ems!amdahl!uunet!csdev!ll1a!spl1!laidbak!att!rutgers!tut.cis.ohio-state.edu!accelerator!baloo.eng.ohio-state.edu!abali 5c5 < Message-ID: <956@accelerator> --- > Message-ID: <8548@spl1.UUCP> 8c8 < Sender: news@accelerator --- > Sender: news@spl1.UUCP [87] [8:41am] tut:/usr/spool/news/comp/sys/next> diff 617 711 1c1 < Path: tut.cis.ohio-state.edu!accelerator!baloo.eng.ohio-state.edu!abali --- > Path: tut.cis.ohio-state.edu!husc6!uwvax!tank!nic.MR.NET!shamash!nis!ems!amdahl!uunet!csdev!ll1a!spl1!laidbak!att!rutgers!mailrus!tut.cis.ohio-state.edu!accelerator!baloo.eng.ohio-state.edu!abali 5c5 < Message-ID: <967@accelerator> --- > Message-ID: <8735@spl1.UUCP> 8c8 < Sender: news@accelerator --- > Sender: news@spl1.UUCP It appears to me that site spl1 has taken the article in, chewed on it a while, and then reposted it to the network again. This is Bad. Naughty boy. As to why it got back here and went out yet again, I don't know. Normal Path: audit trails should have kept husc6 from handing it back to us since we already appeared in that list. Regardless, it was re-accepted for what were evidently legitimate reasons: a unique Message-ID. My map files show spl1 as the Software Public Library in Chicago. Could the admin of this site please take a look? Thanx, --Karl
