Two same rsync commands give different results on two debian mirrors.
Hi all, See the following commands: ___________________________ $ rsync -rmnv -f +_README -f -_* ftp.is.co.za::mirror/ftp.debian.org/ ftp.us.debian.org/debian [snipped] receiving file list ... done sent 23 bytes received 9 bytes 1.42 bytes/sec total size is 0 speedup is 0.00 (DRY RUN) $ rsync -rmnv -f +_README -f -_* ftp.cn.debian.org::debian [snipped] receiving file list ... done drwxr-xr-x 4,096 2015/04/14 11:34:19 . -rw-rw-r-- 1,370 2015/01/10 18:21:28 README sent 47 bytes received 1,389 bytes 574.40 bytes/sec total size is 1,370 speedup is 0.95 (DRY RUN) _________________________ Why the same rsync commands give different results on the above two debian mirrors? The first one failed to find anything even the README exists, while the second one succeed for the job. Any hints on this issue?

Why do you said I have used a wrong rsync direcory tree. See my above notes for detail. In fact, the issue I meet is as follows, see the following for detail: 1- If I append the `/' in the end of the tree, I'll succeed: werner at debian:~$ rsync -rmnv -f +_README -f -_* ftp.is.co.za::mirror/ ftp.debian.org/ftp.us.debian.org/debian/ [snipped] receiving file list ... done drwxr-xr-x 4,096 2015/04/13 11:18:19 . -rw-rw-r-- 1,370 2015/01/10 18:21:28 README sent 130 bytes received 886 bytes 96.76 bytes/sec total size is 1,370 speedup is 1.35 (DRY RUN) 2- If I don't use the `/' in the end of the tree, the rsync will fail to retrieve anything: werner at debian:~$ rsync -rmnv -f +_README -f -_* ftp.is.co.za::mirror/ ftp.debian.org/ftp.us.debian.org/debian [snipped] receiving file list ... done sent 23 bytes received 9 bytes 7.11 bytes/sec total size is 0 speedup is 0.00 (DRY RUN) But for the case when use of the following rsync server, both case will succeed: werner at debian:~$ rsync -rmnv -f +_README -f -_* ftp.cn.debian.org::debian [snipped] receiving file list ... done drwxr-xr-x 4,096 2015/04/14 11:34:19 . -rw-rw-r-- 1,370 2015/01/10 18:21:28 README sent 47 bytes received 1,389 bytes 319.11 bytes/sec total size is 1,370 speedup is 0.95 (DRY RUN) werner at debian:~$ rsync -rmnv -f +_README -f -_* ftp.cn.debian.org::debian/ [snipped] receiving file list ... done drwxr-xr-x 4,096 2015/04/14 11:34:19 . -rw-rw-r-- 1,370 2015/01/10 18:21:28 README sent 47 bytes received 1,389 bytes 574.40 bytes/sec total size is 1,370 speedup is 0.95 (DRY RUN) Any hints on this issue?
