Can anyone tell me what the problem is which causes failures like these ? We get one or two a day out of several hundreds of messages; the sender is a 4.3BSD MIPS/1000, running as a Yellow Pages server, while the receiver is a SUN 3 running SunOS 3.5, also a Yellow Pages server. ----- Begin Forwarded Message ----- |From MAILER-DAEMON Fri Dec 2 12:50:56 1988 Date: Fri, 2 Dec 88 12:50:52 GMT Message-Id: <69.8812021250@crete.cs.glasgow.ac.uk> Subject: Returned mail: System file missing To: pp ----- Transcript of session follows ----- 554 hawaii.ether... 554 System file missing 554 PAT@LEVA.ICF.LEEDS.AC.UK...

Here are two possible answers: If the site is running sendmail, it could mean that there is a problem with opening their sendmail.cf, or that sendmail cannot get the service number using getservbyname. There can be more... search for EX_OSFILE in the source if you have it.. -- Eliot Lear [lear@net.bio.net]

on a 4.3BSD MIPS/1000 system run as an YP server.
Andrew.Findlay@brunel.ac.uk (Andrew Findlay) brought up:
Looking through the Sendmail source (5.52 with IDA in my case) I can
only see two cases where EX_OSFILE is referenced. One occurs if
sendmail.cf cannot be opened, and the other if the smtp service
cannot be found from services.byname.
Here's my 2 cents: We run a few VAXen with MtXinu 4.3BSD and one
annoying thing was "getservbyname()" that simply didn't make it,
sometimes...
We called MtXinu and there showed to be an error in "ndbm.c",
which made "ypserv" loose track of next entry in "services.byname"
(which is the only map that is scanned instead of being directly
accessed) *if* somebody else had called in the meantime (yes, a
real Heisenbug :-).
The error does not seem to exist in SunOS 3.* so you could possibly
test by using "/usr/etc/yp/ypset" to point to either Sun or MIPS as
server and then do several "ypcat services" in parallell and compare
the output.

We're running sendmail-5.65+IDA-1.3.5 on a uVax II running Mt.Xinu 4.3 BSD. This machine is being used as a mailhost for many worstations on campus and recently many users are getting messages bounced back with the following info in the header: ... 451 makeconnection: server "smtp" unknown: Address already in use 554 casbah.acns.nwu.edu (tcpld)... 554 System file missing 554 <galanter@casbah.acns.nwu.edu>... System file missing ... One problem is that we can't find a deterministic method of reproducing the problem. If a message bounces, quit often sending it a second time will get it through. One more piece of information...when running sendmail in address test mode, no matter what sendmail.cf I try (I grabbed a couple from a couple other machines just to test them) it gives the following information: accuvax 128 # /usr/lib/sendmail -bt ADDRESS TEST MODE Enter <ruleset> <address> [Note: No initial ruleset 3 call] > 0 nims@acns.nwu.edu rewrite: ruleset 0 input: nims @ acns . nwu . edu rewrite: ruleset 3 input: nims @ acns . nwu . edu rewrite: ruleset 8 input: nims @ acns . nwu . edu rewrite: ruleset 8 returns: nims @ acns . nwu . edu rewrite: ruleset 6 input: nims < @ acns . nwu . edu > rewrite: ruleset 6 returns: nims < @ accuvax . nwu . edu > rewrite: ruleset 3 returns: nims < @ accuvax . nwu . edu > rewrite: ruleset 6 input: nims < @ accuvax . nwu . edu > rewrite: ruleset 6 returns: nims < @ accuvax . nwu . edu > rewrite: ruleset 0 returns: $# local $: nims > Even though it gives the Note about ruleset 3, it still seems to work. Any advice would be helpfull. Thanks. =============================================================================== Christopher D.

I've suggest you are running YP (NIS) on your machine? I've seen this problem on my systems also. The problem comes from ypserv, which can't serve simultaneous accesse correctly in many implementations. We found this bug on our PCS/Cadmus system as well as on a CDC box (really a MIPS ). Both systems have now a patched ypserv installed, which clearly resolves the problem. There is a simple way to determine if YP is the problem. Write a simple program, which querys for a service in an endless loop, and start it twice (in background). Here is my test program: If YP is the problem it should dwarf about unknown service sometimes. #include <sys/types.h> #include <sys/socket.h> #include <netinet/in.h> #include <netdb.h> #include <stdio.h> #define SERVICE "time" main(argc,argv) int argc; char *argv[]; { struct servent *sp; long i; i = 0; for (;;i++) { sp = getservbyname(SERVICE, "tcp"); if (sp==NULL) { fprintf(stderr, "%s: unknown service, loop %d\n",SERVICE,i); } } } Sincerely, Klaus Steinberger -- Klaus Steinberger Beschleunigerlabor der TU und LMU Muenchen Phone: (+49 89)3209 4287 Hochschulgelaende FAX: (+49 89)3209 4280 D-8046 Garching, Germany BITNET: K2@DGABLG5P Internet: k2@bl.physik.tu-muenchen.de
