Unable to mount CIFS Alfresco 3.2 share under CentOS 5.4

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

I am trying to setup a Alfresco Community Edition 3.2r2 installation on CentOS 5.4.  The installation is working properly except that I am unabled to mount the CIFS AVM share.

The current properties in the alfresco-global.properties file are:

cifs.enabled=true
cifs.ipv6.enabled=false
cifs.tcpipSMB.port=1445
cifs.netBIOSSMB.sessionPort=1139
cifs.netBIOSSMB.namePort=1137
cifs.netBIOSSMB.datagramPort=1138‍‍‍‍‍‍

Using the following command :

# mount -t cifs //127.0.0.1/AVM /mnt/alfresco-wcm -o user=admin,pass=admin,port=1445‍

I get the response :

mount error 111 = Connection refused
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)‍‍

What is strange is that I am able to connect using the smbclient, a list inquiry:

# smbclient -L 127.0.0.1 -p 1139 -U admin%admin‍

returns:

Domain=[262262-FRESCO01] OS=[Java] Server=[Alfresco CIFS Server 5.0.0]

        Sharename       Type      Comment

Connection to 127.0.0.1 failed (Error NT_STATUS_CONNECTION_REFUSED)
NetBIOS over TCP disabled – no workgroup available‍‍‍‍‍‍‍‍‍‍‍

I can connect to the share using the smbclient, update files, etc without any problem, but for some reason I can't mount the share.  I would appreciate any comments or suggestions.

Thanks!

The mount.cifs implementation for CentOS 5.4 appears to ignore the "port=" option from being recognized.  Sniffer showed that despite setting port=1445, SYN's going to 445, 139 but not 1445.

Work around is to use port redirect in IPTables, something along these lines:

echo 1 > /proc/sys/net/ipv4/ip_forward
modprobe iptable_nat
iptables -t nat -F
iptables -t nat -A OUTPUT -d 127.0.0.1 -p tcp –dport 445 -j REDIRECT –to-ports 1445
‍‍‍‍‍‍

(or, similar rule in PREROUTING chain)

Now this works for me:
mount -t cifs -o user=admin,password=admin,rw //127.0.0.1/AVM /mnt/avm

Hope that helps.
