[SOLVED] rsync sending data from the client to the server?

mengoshmink · 06-29-2010, 04:05 AM

Hi all,
I hope someone can shed some light on what I am doing. I am wondering if I just have things back to front.

Server (MESH):
Fedora 13
Firewall ports open tcp 22(ssh), tcp 873(rsync)
sshd service started

Client (RADIUS):
Fedora 13
Firewall ports open tcp 22(ssh)
sshd service started

Step 1.
Create network eg hardware, network address etc

Step 2.
Test network
ping client to server

Quote:

[mengoshmink@RADIUS ~]$ ping -c 3 mesh
PING mesh.config (192.168.1.72) 56(84) bytes of data.
64 bytes from mesh.config (192.168.1.72): icmp_seq=1 ttl=64 time=0.392 ms
64 bytes from mesh.config (192.168.1.72): icmp_seq=2 ttl=64 time=0.289 ms

rtt min/avg/max/mdev = 0.282/0.321/0.392/0.050 ms
[mengoshmink@RADIUS ~]$

ping server to client

Quote:

[mengoshmink@MESH ~]$ ping -c 3 radius
PING radius.config (192.168.1.69) 56(84) bytes of data.
64 bytes from radius.config (192.168.1.69): icmp_seq=1 ttl=64 time=0.303 ms

rtt min/avg/max/mdev = 0.292/0.303/0.316/0.022 ms
[mengoshmink@MESH ~]$

Step 3.
Create a folder and files on the server and client for test purposes
Client

Quote:

[mengoshmink@RADIUS ~]$ ls -l /tmp/test/
total 0
-rw-rw-r--. 1 mengoshmink mengoshmink 0 Jun 29 00:40 testRADIUS
-rw-rw-r--. 1 mengoshmink mengoshmink 0 Jun 29 09:34 testRADIUS-1
[mengoshmink@RADIUS ~]$

Server

Quote:

[mengoshmink@MESH ~]$ ls -l /tmp/test/
total 0
-rw-rw-r--. 1 mengoshmink mengoshmink 0 Jun 29 07:54 testMESH
-rw-rw-r--. 1 mengoshmink mengoshmink 0 Jun 29 07:54 testMESH-2
[mengoshmink@MESH ~]$

Step 4.
Create server-side config file

Quote:

[root@MESH mengoshmink]# nano /etc/rsyncd.conf

Code:

#motd file = /etc/rsyncd.motd
log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock

[testpath]
   path = /tmp/test
   comment = Test comment
   uid = nobody
   gid = nobody
   read only = no
   list = yes
   auth users = mengoshmink
   secrets file = /etc/rsyncd.scrt

Step 5.
Create server-side secrets file and set access to it

Quote:

[root@MESH mengoshmink]# nano /etc/rsyncd.scrt

Code:

mengoshmink:secret

Quote:

[root@MESH mengoshmink]# chmod 600 /etc/rsyncd.scrt

Step 6.
Start rsync daemon on the server

Quote:

[root@MESH mengoshmink]# rsync --daemon
[root@MESH mengoshmink]#

Step 7.
View file list on the server, remotely

Quote:

[mengoshmink@RADIUS ~]$ rsync rsync://mesh/testpath/
Password:
drwxrwxr-x 4096 2010/06/29 09:17:24 .
-rw-rw-r-- 0 2010/06/29 07:54:04 testMESH
-rw-rw-r-- 0 2010/06/29 07:54:14 testMESH-2
[mengoshmink@RADIUS ~]$

Step 8.
Transfer files from the server

Quote:

[mengoshmink@RADIUS ~]$ rsync -rv rsync://mesh/testpath/ /tmp/test/
Password:
receiving incremental file list
testMESH
testMESH-2

sent 103 bytes received 203 bytes 122.40 bytes/sec
total size is 0 speedup is 0.00

Quote:

[mengoshmink@RADIUS ~]$ ls -l /tmp/test/
total 0
-rw-rw-r--. 1 mengoshmink mengoshmink 0 Jun 29 09:54 testMESH
-rw-rw-r--. 1 mengoshmink mengoshmink 0 Jun 29 09:54 testMESH-2
-rw-rw-r--. 1 mengoshmink mengoshmink 0 Jun 29 00:40 testRADIUS
-rw-rw-r--. 1 mengoshmink mengoshmink 0 Jun 29 09:34 testRADIUS-1
[mengoshmink@RADIUS ~]$

All looks good so far

Now for the problem
Transfer files to the server

Quote:

[mengoshmink@RADIUS ~]$ rsync -rv /tmp/test/ rsync://mesh/testpath/
Password:
sending incremental file list
testMESH
testMESH-2
testRADIUS
testRADIUS-1
rsync: mkstemp "/.testMESH.rc5Wzb" (in testpath) failed: Permission denied (13)

rsync: mkstemp "/.testRADIUS.qlYvTD" (in testpath) failed: Permission denied (13)
rsync: mkstemp "/.testRADIUS-1.qM9j3m" (in testpath) failed: Permission denied (13)

sent 229 bytes received 84 bytes 69.56 bytes/sec
total size is 0 speedup is 0.00
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1042) [sender=3.0.7]
[mengoshmink@RADIUS ~]$

FYI
I have not written it here but I can successfully transfer files by ssh / scp.

Any comments or suggestions welcome.
Thank you in advance.

Right so it's failing to make a temp file in the root of the filesystem, should that user be able to do that? you can use the -T or --temp-dir option to specify a different location for temporary files.

I think I have found the solution.

Edited /etc/rsyncd.conf

Code:

#motd file = /etc/rsyncd.motd
log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock

[testpath]
   path = /tmp/test
   comment = Test comment
   uid = mengoshmink
   gid = mengoshmink
   read only = no
   list = yes
   auth users = mengoshmink
   secrets file = /etc/rsyncd.scrt

Command run on the client

Quote:

[mengoshmink@RADIUS ~]$ rsync -rv /tmp/test/ rsync://mesh/testpath/
Password:
sending incremental file list
testRADIUS-1
testRADIUSdir/
testRADIUSdir/testRADIUS

sent 171 bytes received 50 bytes 49.11 bytes/sec
total size is 0 speedup is 0.00

The critical change being the UID and/or the GID in the server-side /etc/rsyncd.conf Everything else has remained the same.

Quote:

uid
This parameter specifies the user name or user ID that file transfers to and from that module should take place as when the daemon was run as root. In combination with the "gid" parameter this determines what file permissions are available. The default is uid -2, which is normally the user "nobody".

gid
This parameter specifies the group name or group ID that file transfers to and from that module should take place as when the daemon was run as root. This complements the "uid" parameter. The default is gid -2, which is normally the group "nobody".

I have tried commenting out the two lines and I get an error, if I change just the uid or gid the file transfers successfully. However I would recommend you set the uid when the files are received they are chown-ed to that uid with read and write access whereas group and other members only have read access.

For example:
/etc/rsyncd.conf

Code:

#motd file = /etc/rsyncd.motd
log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock

[testpath]
   path = /tmp/test
   comment = Test comment
   uid = mengoshmink
   gid = nobody
   read only = no
   list = yes
   auth users = mengoshmink
   secrets file = /etc/rsyncd.scrt

Files on the client:

[mengoshmink@RADIUS ~]$ ls -lR /tmp/test/

I have yet to try using different uid/gid values for different rsync 'modules' to see what happens.

I have done a quick test using the -a option (which includes -p to preserve permissions) and it has given me the same results as above but this could well be me doing something wrong.

Ultimately transmitting the files by ssh (rsync -e /usr/bin/ssh) is a much better method but I have yet to test to see what it does (if anything) to the file/folder permissions.

Did you try "rsync -rv --inplace /tmp/test/ rsync://mesh/testpath/" ?

mengoshmink · 09-11-2010, 04:33 PM

No, --inplace is not a switch that I had tried. What does it do?
