Rsync Hangs 100% of the time when copying files from win2k machin es to linux
Hey guys, I've been working with rsync for the last couple weeks and I
really need some help here. Linux to Linux transfers are working
beautifully, but for the life of me I can't get transfers from win2k to
work. I have the exact problem that was reported by Mark de Jong on Tue, 16
Jul 2002.
I'm using the lastest version of cygwin, with rsync 2.5.5 and ssh 3.5p1 for
my tests. The problem occurs on every windows box I've tried it on. (Half a
dozen machines, mixed NT 4.0 and Win2k). It happens every time. It's very
important to me that I fix this problem but I think I'm going to need some
help.
It happens after I issue the following command from the linux box:
rsync -avx --progress --ignore-errors --delete-excluded --delete -vvv
--exclude-from=system/excludes -e ssh
Administrator@10.0.0.159:/cygdrive/c/WINNT deleteme/
Here is the tail end of it's output:
recv_generator(WINNT/twain_32/fjscan/fcpa,9712)
recv_generator(WINNT/twain_32/logiscan,9713)
recv_generator(WINNT/twain_32/miitwain,9714)

recv_generator(WINNT/winrep.exe,9728)
recv_generator(WINNT/wmsetup.log,9729)
recv_generator(WINNT/yacs.log,9730)
generate_files phase=1
It hangs right there indefinatly. 0% processor utilization on both
machines. After I hit CTRL+C the following prints out:
^C_exit_cleanup(code=20, file=rsync.c, line=229): entered
rsync error: received SIGUSR1 or SIGINT (code 20) at rsync.c(229)
_exit_cleanup(code=20, file=rsync.c, line=229): about to call exit(20)
_exit_cleanup(code=20, file=rsync.c, line=229): entered

_exit_cleanup(code=20, file=rsync.c, line=229): about to call exit(20)
root@raid:/data/remote-backups#
When it hangs there are 2 process running on the linux box and one on the
windows box.
When I attach to the first one (pid 7276) on the linux box it's sitting in
select. If I do a back trace part of the stack doesn't show up (always
showing weird stuff like errno or 0x8 or 0x5 having called select), so I do
a "n" to single step until it emerges from select I'm left with
the
following back trace which makes sense:
#0 writefd_unbuffered (fd=4, buf=0x817f038 "\004%", len=3876) at

If I then detach and attach to process number 2 (7284) on the linux box,
then single step until it emerges from select I get this back trace:

When I attach to the process running on the windows box, and do a back trace
I get very confused.

GDB then hangs up there. I can't even hit ctrl+C. I've tried the
cygwin
mailing list for help, but I've yet to get a single response :( I'm
hoping
this one will be better.
As possible further (but perhaps unrelated information) Mr Jong eventually
gave up and used rsync in daemon mode. I tried that too, but the rsync
instance on the win2k dies with the following message in the event viewer
part way through the transfer (But it does actually start copying files):
rsync error: error in rsync protocol data stream (code 12) at io.c(463).
Thankyou for reading this far, if you have any suggestions at all,
please post them. CC me if you can remember too, I'm not subscribed to the
list, but I'll be reading in the archive.
