We have an odd situation where we have an rsyncd server running, that generates a password mismatch error when access attempts are made from some hosts, but not others. rsync from host1 is as follows rsync -vv user@server::STEREO opening tcp connection to server port 873 opening connection using --server --sender -vv --list-only . STEREO Password: @ERROR: auth failed on module STEREO rsync error: error starting client-server protocol (code 5) at main.c(1171) and on host2 rsync -vv user@server::STEREO/ opening tcp connection to server port 873 Password: drwxr-xr-x 4096 2008/10/29 14:13:41 . -rw-r--r-- 19942 2008/10/23 10:26:19 wget-log -rw-r--r-- 1561285 2008/10/28 15:13:44 wget-log.1 -rw-r--r-- 325553 2008/10/29 14:31:51 wget-log.10 -rw-r--r-- 390484 2008/10/29 14:36:23 wget-log.11 -rw-r--r-- 240940 2008/10/29 14:27:40 wget-log.12 -rw-r--r-- 2276026 2008/10/28 16:52:36 wget-log.2 -rw-r--r-- 18620 2008/10/28 13:49:02 wget-log.3 -rw-r--r-- 10851300 2008/10/28 22:08:16 wget-log.4 -rw-r--r-- 1395844 2008/10/29 03:09:36 wget-log.5 -rw-r--r-- 12329470 2008/10/29 11:03:54 wget-log.6 -rw-r--r-- 2522306 2008/10/29 04:02:25 wget-log.7 -rw-r--r-- 934565 2008/10/29 02:40:20 wget-log.8 -rw-r--r-- 1364752 2008/10/29 02:50:01 wget-log.9 delta transmission enabled sent 102 bytes received 544 bytes 184.57 bytes/sec total size is 208957904 speedup is 323464.25 where the servers rysnd.log shows 2008/10/29 17:05:31 [21581] connect from host1 (*.*.*.*) 2008/10/29 17:05:36 [21581] auth failed on module STEREO from host1 (*.*.*.*): password mismatch 2008/10/29 17:07:23 [21604] connect from host2 (*.*.*.*) 2008/10/29 17:07:27 [21604] rsync on STEREO/ from user@host2 (*.*.*.*) 2008/10/29 17:07:27 [21604] sent 544 bytes received 102 bytes total size 208957904 where host1 is a Solaris box running rsync version rsync version 2.6.6 protocol version 29 Copyright (C) 1996-2005 by Andrew Tridgell and others <http://rsync.samba.org/> Capabilities: 64-bit files, socketpairs, hard links, symlinks, batchfiles, inplace, no IPv6, 64-bit system inums, 64-bit internal inums and host2 is a Linux box running rsync rsync version 2.6.3 protocol version 28 Copyright (C) 1996-2004 by Andrew Tridgell and others <http://rsync.samba.org/> Capabilities: 64-bit files, socketpairs, hard links, acls, symlinks, batchfiles, inplace, IPv6, 64-bit system inums, 64-bit internal inums, SLP Can anyone shed some light on this behaviour?
