Hi. I'm trying to compile Zephyr on:
tsinghua% uname -a
NetBSD tsinghua 1.3.2 NetBSD 1.3.2 (GENERIC) #0: Sun May 10 22:48:06 MEST 1998 pk@flambard:/usr/src1/sys/arch/sparc/compile/GENERIC sparc
tsinghua% ./config.guess
sparc-unknown-netbsd1.3.2
I'm using the versions of K4 and libdes that come in the NetBSD
"domestic" package.
I grabbed, 'sh configure'd and compiled what I found under:
/afs/dev.mit.edu/source/src-current/athena/lib/hesiod
/afs/dev.mit.edu/source/src-current/athena/lib/ss
/afs/dev.mit.edu/source/src-current/athena/lib/zephyr
I ran the zephyr configure with --with-hesiod, --with-krb4, and with
CPPFLAGS and LDFLAGS set to find the already-built hesiod and ss, then
I did 'make'.
And everything compiled and linked.
zhm finds the MIT zephyr servers, zwgc gets a ticket for
zephyr.zephyr@ATHENA.MIT.EDU, and, on my athena-sun window, I even
see a notice that I've logged in on tsinghua. zstat works fine.
But that's about it. On tsinghua, I can't do a 'zctl ret' to see what
I'm subscribed to; that times out. I can't zwrite anyone. From an
athena-sun, I can zwrite myself and get it there, but I won't get it on
tsinghua, even though a 'znol -u fredette' from an athena-sun shows me
logged in there.
I started doing a little debugging. I've compiled zhm with all of
its debugging code and sat there and watched it and a tcpdump: a
'zctl ret' gets a packet to zhm, zhm sends it to whatever server,
the server sends something back to zhm, and zhm gives it to zctl.
Running the 'zctl ret' inside of gdb, it looks like ZCheckAuthentication
is failing checking that result packet: des_quad_cksum isn't returning
the expected value that's in notice->z_checksum.
Thinking this was a problem with the NetBSD-provided libdes (it's
the one from Eric Young) I built things with the old, 1991-vintage
MIT libdes library, and got the same results.
Any clues? Anyone ever try to build this on NetBSD/SPARC before?
Am I right in thinking that there's a problem with my checksums?
This isn't important, I just like having zephyrs on my desktop
machines.
Thanks for your time,
Matt
