DO NOT REPLY [Bug 4633] New: rsync mirror fails when using -a/-o/-g options
https://bugzilla.samba.org/show_bug.cgi?id=4633
Summary: rsync mirror fails when using -a/-o/-g options
Product: rsync
Version: 2.6.3
Platform: x86
OS/Version: Windows XP
Status: NEW
Severity: major
Priority: P3
Component: core
AssignedTo: wayned@samba.org
ReportedBy: klaus.steden@thomson.net
QAContact: rsync-qa@samba.org
Attempting to rsync between two RHEL4 systems across WAN.
When using the following command-line, everything works fine:
rsync -rlptD --verbose --progress rsync://jeeves.trno/redhat/RHEL4/ /usr/tmp
Things fail when using the following command-line:
rsync -rlptDo --verbose --progress rsync://jeeves.trno/redhat/RHEL4/ /usr/tmp
(will also fail if using '-g' instead of '-o', or using
'-a' option instead of
'-rlptogD').
Failure message on the client side is:
receiving file list ...
rsync: connection unexpectedly closed (4 bytes received so far) [receiver]
rsync error: error in rsync protocol data stream (code 12) at io.c(359)
Running the 'rsync-debug' wrapper (found on the rsync site) to generate
strace
logs displays a whole pile of strange-looking errors on the server side:

However, on the server side, /etc/localtime exists, as do /etc/ld.so.cache,
/etc/passwd, and /lib/libnss_nis.so.2. So I'm scratching my head on this one
... anyone ever seen this sort of failure from rsync before?

DO NOT REPLY [Bug 4633] rsync mirror fails when using -a/-o/-g options

------- Comment #1 from klaus.steden@thomson.net 2007-05-17 13:49 MST -------
Did some more digging around in Google, and found this:
http://lists.centos.org/pipermail/centos/2005-March/003386.html
and this:
http://lists.centos.org/pipermail/centos/2005-March/003389.html
I ran the sample code on the rsync server in the aforementioned bug, and was
able to reproduce the behaviour I'm seeing with rsync (according to
'strace',
the same flailing search for 'libnss_nis.so' takes place, followed by a
segfault).
Now the question is ... is rsync chroot'ing by default? Should it? (Can I
make
it not do that? :-)

------- Comment #2 from klaus.steden@thomson.net 2007-05-17 13:53 MST -------
This is a problem with libc, not with rsync, so I'm closing it. Sorry for
the
avalanche of messages, inserting 'use chroot = no' into /etc/rsyncd.conf
eliminates the segfault problem.
