Hmmm.

I think the clue here may be that you are using udp on the server and tcp on the client? Clearly the server is attempting to contact the client, but the client is not listening.

What does your LaunchDaemon script say? In particular, the ipv4 section, is the SockType key set to stream? If so then that means that your client is listening only for TCP. You should be able to confirm that by checking netstat:

% netstat -na | less

The lines reported on my MBP is related to amanda are:

tcp6 0 0 *.10080 *.* LISTEN tcp4 0 0 *.10080 *.* LISTEN

Meaning that I'm listening on TCP port 10080, both ipv4 and ipv6 (though I don't use ipv6, we can ignore that).

Now, i passed the client in UDP mode :

saroumane:~ root# netstat -na | grep 10080
udp6       0      0  *.10080                *.*
udp4    1251      0  *.10080                *.*
saroumane:~ root#

If your netstat produces a similar result then that may point to udp vs. tcp.

For that matter, if netstat isn't showing 10080 then that would tend to indicate that the launchd script isn't running properly.

If all else fails, try using tcpdump on the client to watch the server attempting to connect and troubleshoot from there.

On the client, the tcpdump shows :
9:43:37.378315 IP backup.918 > saroumane.nt.fr.amanda: UDP, length 123
19:43:47.378418 IP backup.918 > saroumane.nt.fr.amanda: UDP, length 123
19:43:57.378022 IP backup.918 > saroumane.nt.fr.amanda: UDP, length 123

Then, on the server, the amcheck command shows :

-bash-3.1$ amcheck saroumane

and don't see errors in these logs.

The client and the server is now in UDP mode.

thanks a lot for your help.

Best regards,

I'm running Amanda 2.5.2p1 on Fedora 9 (server) and three MacBook Pros (client) (10.4.X and 10.5.X) without difficulty.

A few quick questions that might point in the right direction:

1. What version of amanda are you running on the Macs?

The version is 2.5.1p3 (like the amanda sever).

2. What config options did you use?

./configure --with-user=amandabackup --with-group=admin --with- config=saroumane --without-server --prefix=/usr/local/amanda --with- amandahosts --with-portrange=50000,50014 --with-bsdtcp-security

3. What user is running the amanda client on the Macs?

amandabackup 14105 0.1 0.0 75356 580 ?? Rs 9:43AM 0:00.06 (launchproxy)

4. What is the contents of .amandahosts in that user's home directory

# machine               utilisateur
backup                  amandabackup amdump

and backup is (in the /etc/hosts) :

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1       localhost
255.255.255.255 broadcasthost
::1             localhost
fe80::1%lo0     localhost

192.168.50.20   backup backup.nouveauxterritoires.fr

5. What is in /tmp/amanda and do the contents of those files point show any errors?

on the client, there are not logs in the /tmp/amada/

On the server, there are logs in the /tmp/amamda/server/saroumane (the name of the computer's client) :

amcheck: debug 1 pid 9472 ruid 33 euid 0: start at Sat Jul 19 14:51:39 2008 amcheck: debug 1 pid 9472 ruid 33 euid 33: rename at Sat Jul 19 14:51:39 2008

On the amanda server, my /etc/xinetd.d/amanda configured like this :

service amanda
{

only_from = localhost 82.235.225.240 127.0.0.1 intranet supervision globtrans saroumane

      socket_type     = dgram
      protocol        = udp
      wait            = yes
#       user            = $USER
#       group           = $GROUP
      user            = amanda
      group           = disk
      groups          = yes
#       server          = $AMANDAD_PATH/amandad
      server          = /usr/local/amanda/libexec/amandad
      server_args     = -auth=bsd amdump amindexd amidxtaped
      disable         = no
}


The protocol used is 'udp'
and on my cMac OSX client is (in the configure options) -auth=bsdtcp

This configuration can be a problem ?




cheers

The amanda client is apprently ok (with netstat).

But the amcheck command fail already !!

Good to hear you're building on a Mac!

Have you set up the necessary launchd script on the mac?  There's
