CIFS troubleshooting

paulhh — Tue, 07 Feb 2006 17:22:57 GMT

If you cannot map a drive to the Alfresco CIFS server then it's likely a name lookup problem. Check whether you are using WINS or broadcast lookups on your LAN. If you're using broadcasts, is your network split into more than one subnet? Did you change the broadcast mask setting in the file-servers

Re: CIFS troubleshooting

When running the Alfresco CIFS server under linux make sure that the firewall is open for CIFS access. In Suse linux using Yast, go to Security and Users, Firewall, then either disable the firewall or in the Allowed Services add Samba Server via the Service To Allow drop down menu.

In the file-servers.xml file change the <broadcast> setting to match the broadcast mask of your network. Use ifconfig and look for the BCast: setting for the main network adapter.

You could try changing the <host name="…"/> setting to use a fixed name, such as <host name="BOSDOCS1A"/>.

If installing Alfresco on a stand-alone system, not connected to any network,
we try to map the CIFS server, (pure standard installation), and get
"The mapped network drive could not be created because the following error has occurred: The network location cannot be reached. …"

Once you connect that PC to a network, any network basically,
the CIFS server can be mapped to a network drive.

The system is installed in a standard way.
Any settings we could change to solve this problem and Demo Alfresco completely stand-alone?
We could add an entry in the lmhosts file?

In the config file : file-servers.xml is code setting alfresco's SMB port to 1139 and a comment about using firewall redirects to these alternate port numbers.

Does this mean that it is possible to run samba and have Alfresco CIFS up on the same network?

It is not clear to me how a user would be able to connect to the alfresco CIFS when samba is running elsewhere.

Is this just URL based? I see in the Packt book that one uses the URL http://theservername/alfresco/intranet/somefolder
as the XP "my network places" path. Does this imply some sort of tomcat conf change to map the "intranet" directory to the correct port?
or should I be doing:
http://theservername:1139/alfresco/intranet/somefolder

A related question:
We have a large directory structure that we have used for years to put documents on. While it seems quite possible to simply drag the root of that directory structure across to a webdav / cifs alfresco'ised space, this will create a large duplication of the documents on the native systems.
My question: is there a way of pointing alfresco at an existing directory tree and having it in a batch manner build it's indexes and not relocate the documents?

At this point my interest is simply in getting the indexed searching in place. Creating workflow etc would happen case by case after it was "known" by alfresco. Then at some point we could turn off samba on these folders and use only alfresco/CIFS.

Maybe I'm approaching this all wrong? opinions? suggestions? anyone?

My question: is there a way of pointing alfresco at an existing directory tree and having it in a batch manner build it's indexes and not relocate the documents?

Answering my own second question:

Well after looking at the details of how things seem to persist under alf_data I'd say the answer is a loud "no". The rather long key info embedded in the pathnames to where the docs persist under alf_data is
a) not likely to be compatible with some arbitrary directory hierarchy that already exists.
b) probably vital to making alfresco work.

On the first question:

Does this mean that it is possible to run samba and have Alfresco CIFS up on the same network?

it turned out to be a case of making sure the Alfresco CIFS and our Samba appear as different IP addresses on the network, then they cohabit just fine.

Related: the "tomcat/alfresco runs as root" aspect of things does make people nervous about using webdav outside our firewall though…

Actually, only really needed was to add two DLL files to the path, and remove the domain that I mentioned before, It works fine now no errors.

Hi, My case is:

on Windows 2003, install Alfresco 2.1 with all default setting.
Then create a Alfresco user kzhou by webclient and a space Kent Blogs.

On Windows 2003, I can access CIFS by \\myservera\Alfresco\Kent Blogs with user kzhou.

Then I try to map Y: to \\myservera\Alfresco\Kent Blogs on another XP machine. When connecting to the server, it ask for username/password,
after try 3 user: kzhou, admin, administraror, I can't connect to CIFS server. The message is:
The network folder specified is currenctly mapped using a different name and password. To connect using a different user name and password, first dissconnect any existing mappings to this network shares.

Even if I disconnect all existing mapping, still can not connect CIFS with same error message.

On XP when using nbtstat , get info as:

C:\Documents and Settings\kzhou>nbtstat -a myservera

….

I have Alfresco 2.1 running in Ubuntu 7.1. I am able to connect to Alfresco locally, but when I try to do so on a Windows machine on the LAN it will not authenticate me. I know that a standalone samba server typically requires you to shadow a Windows NT-friendly version of a password in order to authenticate from a Windows client. Is it possible that I need to do something similar for Alfresco?

Edit: I should add I am using the Enterprise edition of Alfresco.

Re: CIFS troubleshooting

marctsg — Thu, 24 Jan 2008 18:32:15 GMT

After further testing, it seems I can connect to the CIFS server if I use the server's IP address. The CIFS server is reporting its IP address to the CIFS server as 127.0.1.1 which caused a machine attempting to connect by hostname to try to conenct to itself.

This workstation is not part of a domain and acquires its IP address through DHCP. Not being an expert in Linux, I don't know if any other way exists for the OS to map the hostname other than using the hosts file, which is what I have done.

I'm guessing that the CIFS server is reporting the address that I've mapped to the hostname in the hosts file, but I don't understand why that would be. The stand-alone samba daemon did not do this. Is there a configuration option that I am missing?

I have a similar setup (VM without DNS Server) and I took you comment to the /etc/hosts file with the entries below and it worked at once

127.0.0.1 localhost

Hi all,

this probably goes without saying, but if you use iptables to redirect the ports make sure,
that the iptables also accept incoming connections. In my case I had to specifically open up
the ports. Turns out that in some distros lower ports are blocked. Meaning you can access
the machine with the webclient on Port 8080 and you can also ping the machine but you
cannot connect to it via smb.

It is even funnier since you can connect locally with an smbclient using 127.0.0.1 but
but not with the external IP address. Like 192.168.129.179 does not work …


iptables -A OUTPUT -p tcp –dport 445  -mstate –state NEW,RELATED,ESTABLISHED -j ACCEPT
iptables -A OUTPUT -p udp –dport 139  -mstate –state NEW,RELATED,ESTABLISHED -j ACCEPT

After my first fresh installation,
i create with web interface an alfresco user 'test'with password test.

After that i tried the cif samba login, and i can't login with user test/test to see only test home directory.
How to do this?

Is it possible to log in only with the admin/admin user ?

Thank you in advance (i'm a newbie)

Hello,
I am getting winsock error 10055 "No buffer space available" when trying to access CIFS. I know this is rather a windows problem than alfresco's one, but anyway, has someone experienced with this? My system is running on BeaWeblogic on Windows 2003 server with 4GB of physical RAM. The system is quite loaded with other apps and near all of its memory is constantly allocated, also in netstat there seems to be a lot of connections. I understand what the problem is - but is there any workaround - eg. how to set/tweak the winsock buffers?

To be precise, the exception log:


10:39:17,394 ERROR [alfresco.smb.protocol] Closing session due to exception
org.alfresco.filesys.netbios.win32.WinsockNetBIOSException: 10055:ReceiveSocket - No buffer space available

Hi Giorgo

After my first fresh installation,
i create with web interface an alfresco user 'test'with password test.

When you look around, you will notice some strange phenomenon mentioned - sometimes, persistence pays of (trying again and again, min 3 times), sometimes you have to wait a few minutes. The important thing is - can you reach the mashine with its names "servername" and "servername_a" or "servernamea" (depending on your config) on their ports. Everything else is Alfresco user management.

Oh - the user has to have access rights to the folder in question. 🙂

Thank you, Norgan, I succeded in loggin in with the right user,
creating the versioning system.

I have to answer to other to question to cosider this product great,
first: i added versioning; when i delete a file via cif, can i still find it via alfresco web interface? (standard settings)
second:
And how to activate indexing? every content of the files i put in alfresco (ods, doc and aslo text files) are not
matched by the advanced indexing.

Thank you in advance

Hi Giogio,
regarding 1) Dont know - try it out I would guess though, that deleting will remove the complete object (including versions) from the space. That would be the action, I would expect, by the way.

regarding 2) - Check out the documentation regaring "Search Customization". Since the engine is lucene, every format, that is not supported as of yet, can probably added by developing a proper "parser" plugin.I assume, though, that ODF is supported already, I guess you have a bug in your configuration there.
