DO NOT REPLY [Bug 3839] New: The '/' in the Softlink is missing on the remote Rsyncd server !
https://bugzilla.samba.org/show_bug.cgi?id=3839
Summary: The '/' in the Softlink is missing on the remote
Rsyncd
server !
Product: rsync
Version: 2.5.7
Platform: x86
OS/Version: Windows 98
Status: NEW
Severity: normal
Priority: P3
Component: core
AssignedTo: wayned@samba.org
ReportedBy: louie@unitednet.com.hk
QAContact: rsync-qa@samba.org
Dear all,
When I use rsync with "-l" to backup some softlinks to the remote
Rsyncd
server, the '/' in all softlink files on the remote server has been
removed.
For example: The softlink "test2.txt -> /home/louie/test.txt" will
become to
"test2.txt -> home/louie/test.txt" on the remote server. Therefore,
the OS
cannot locate the right location due to missing '/' when I recover this
softlink from the remote server to the local machine.
Do you know if there is any method to fix this problem ?
Thanks !
Best Regards. Louie

This has been fixed in the CVS version for a while now, which you can try out
via the "nightly" tar files. This sanitizing of symlinks as they get
expanded
is still pretty new, so it would help if folks beat on the code to see if there
are any places where a symlink could escape the top of the module's
hierarchy
that aren't handled yet.
You can also avoid the problem with any rsync by turning chroot on in the
config file.

Can you tell me which version of rsync has fixed this problem ? 'cos I can find that the man page for rsync v2.6.4-3 is still telling us that it will still remove the leading slashes in all symbollinks. See below: man rsyncd.conf use chroot If "use chroot" is true, the rsync server will chroot to the "path" before starting the file transfer with the client. This has the advantage of extra protection against possible implemen- tation security holes, but it has the disadvantages of requiring super-user privileges, of not being able to follow symbolic links that are either absolute or outside of the new root path, and of complicating the preservation of usernames and groups (see below). When "use chroot" is false, for security reasons, symlinks may only be relative paths pointing to other files within the root path, and leading slashes are removed from most absolute paths (options such as --backup-dir, --compare-dest, etc. interpret an absolute path as rooted in the module’s "path" dir, just as if chroot was specified). The default for "use chroot" is true.> You can also avoid the problem with any rsync by turning chroot on in the > config file. >It works for my current version after I have turned chroot on.

https://bugzilla.samba.org/show_bug.cgi?id=3839 ------- Comment #3 from hashproduct+rsync@gmail.com 2006-06-17 09:15 MST ------- (In reply to comment #2)> Can you tell me which version of rsync has fixed this problem ?The problem was fixed in the CVS after the release of 2.6.8, which means that the only way you can get a fixed rsync is to compile it yourself from the source code in CVS. To get the source, you can either check out the source code from CVS or download and unpack the nightly tar file, as Wayne mentioned: http://rsync.samba.org/ftp/rsync/nightly/rsync-nightly.tar.gz Then ./configure, make, su -c 'make install'. -- Configure bugmail: https://bugzilla.samba.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug, or are watching the QA contact.
