Linux – rsync: chdir /test failed : Permission denied (13)

linuxpermissionsrsync

I was trying to get a more complicated module rsyncing, but it seems that I cannot get the most basic example working…

I have a very simple rsyncd.conf file with a single module running under xinetd;

use chroot  = false
strict modes = false
hosts allow = *

[thumbnails]
path = /test
read only = false

The path has been created and has liberal permissions

    # ls -la /test/
    total 16
    drwxrwxrwx  2 root root 4096 Jul 12 21:50 .
    drwxr-xr-x 26 root root 4096 Jul 12 21:50 ..

xinetd has been configured to run rsyncd as the root user (which was the default);

# cat /etc/xinetd.d/rsync   
# default: off
# description: The rsync server is a good addition to an ftp server, as it \
#       allows crc checksumming etc.
service rsync
{
        disable         = no
        socket_type     = stream
        wait            = no
        user            = root
        server          = /usr/bin/rsync
        server_args     = --daemon
        log_on_failure  += USERID
}

xinetd has been restarted;

# service xinetd restart
Stopping xinetd:                                           [  OK  ]
Starting xinetd:                                           [  OK  ]

However a simple rsync command to that module fails;

# rsync -va /root/testfolder/ localhost::thumbnails
@ERROR: chdir failed
rsync error: error starting client-server protocol (code 5) at main.c(1296) [sender=2.6.8]

I am suspecting that rsync might be dropping permission from root to whatever process actually makes the rsync copy, but whatever it is I can't immediatly see what as the daemon, nobody and sync users can all cd and write in /test.

If I run rsync from the command line eg;

# rsync --daemon 
# rsync -va /root/testfolder/ localhost::thumbnails

this works fine.

I tried the following modifications to the rsyncd.conf;

# cat /etc/rsyncd.conf 
use chroot  = false
strict modes = false
hosts allow = *

[thumbnails]
path = /test
read only = false 
uid = 501
gid = 501

where 501/501 is the uid/gid of a new user I created and chowned the /test folder to it, but I get the same problem.

Are you running SELinux? Could you paste the output of ls -lZ /test?
