Moving this topic to the SME 7.x contribs forum, it is more appropriate there. Thanks!

Google the phrase 'SMB signing is mandatory and we have disabled it' for details.

SMB signing is mandatory and we have disabled it.

Reading the results from a google search, this appears related to Win2K3 server.
It says in the server manager panel for DAR2, to use cifs for Windows servers:

"Three file systems are supported. [ext3] for backup to local attached disk. [smbfs] for backup to Windows workstation and SME Server network shares. [cifs] for backup to Microsoft Windows Server. Note if using cifs, target entry above must use IP address. Example: [//10.1.1.1/sharename]."

Hi all

Regarding backup to linux desktop:
Please provide some example syntax of the target field entry of the Dar2 server manager configuration screen; and when backing up the SME server to a linux deskop

Please advise thanks

If you search back a year or so, I think you will find some posts by dmay that answer that.

I can't mount squat 

After searching the posts for about a week, I can't figure out how to use the DAR2 to backup to desktop.
Now what ? I guess look for a decent tape drive so I don't have to think about it anymore, and throw my usb drive in the trash.

Thanks anyhow.

I see I think I understand now,

I've setup my user share on the desktop, however I believe what your telling me that regarding permisssion is denied because on the desktop I need to either add the user to that share, or use the user credentials (user/pass) of the shared resource.

So do you actually put the syntax into the field in the dar2 server-manager field or are you simple calling up the location/directory in that field ?

[dmay]

The panel has separate boxes for Target, Username, Password. Use them appropriately as stated in the panel:

Code: [Select]

Valid targets are an attached local drive or network share.
If backing up to an attached local drive, enter the target mount point of your drive. Example: [/media/usbdisk]. Leave the username and password fields blank.
If backing up to a network share, enter the target in UNC format. Example: [//computername/sharename]. In addition you must enter a valid username/password that is a local account on the target with full access rights to the share.

Target     [                        ]
Username   [                        ]
Password   [                        ]

Hi, Thanks for the reply,

I keep trying to perform a test backup with just (root) listed in the backup selections.

I put in the //computername/share and tried variations of this //computername-desktop/share which in this case happens to be the default computer name that the installation gave me on my desktop, Ubuntu basically calls the computer whatever your user name is. I've tried other combinations //computername/home/user/Desktop/share
//computername-desktop/home/user/Desktop/share
ipaddress//computername/share and other targets I've tried.

I realize the server manager page indicates to just put in the //computername/share and not all this //???/???/??? etc.

Basically the backup seems to get saved to the SME server in inside a file called /auction.foolishlys.com in root directory.

But only sometimes depending on which of those above targets I try.

I've setup the desktop to share using both NFS and then also tried SMB type of share, same results.

I've tried with and without passwords.

I've checked to see if SME sees the share using the smbclient commands such as ( smbclient -NL 10.1.10.188) and/or (smbclient -L 10.1.10.199)

-L//machinename says shares are there.

I'm not sure this is a very good option for backup for me personally as a non-fluent linux user. It's beginning to get a little too complex with all these commands.

If I were more fluent perhaps it would be simple for me.

Perhaps I need to attempt a backup to usb or local drive instead if that could be any simpler for me.

Thanks for the help.
I'll move on to usb or perhaps just a tape backup since the tape backup seems to be as simple as clicking a button.

I have never done this with a linux client but on Winxp it just works.

//Clientname/sharename

(In my setting //Royceh/sme_backup)

This is the same path I would put in to browse the share from another workstation.
I would suggest that you test this from another workstation to be sure the share is available.....

For winxp the filetype is SMBFS and the username and password fields contain the share username and password.
This is all configured from the Disk ARchive panel in server-manager. (No command line needed)

Check the following:

*  Firewall on the workstation. I have had instances of up to three firewalls running on a customer's (windows) workstation at the same time.

*  Can you browse the share from another workstation.

Ubuntu basically calls the computer whatever your user name is.

I don't know anything about Ubuntu but this raises a question for me. Does the Machine host name actually change every time a different user logs on???

What if no user is logged on, does the machine then not have a hostname???

just ignore this post if it is not applicable. Reading through the thread I am not sure if I can follow WHO is  having problems with WHAT 

[Agent86]

mercyh- Thanks for the reply,

I believe this original old post has been concluded, but my questioning in other posts led me here and I sort of stoked it back up again.

So basically from my first post from Agent86 downward is what I'm working on with my backup topic.

However not specifically permissions, although I guess it could be permissions I'm not sure at this point.

Your response has been helpful.

So in response to your notes I can see the shares from other desktops and also I see them when I login with ssh as root to the SME server and do the smbclient commands I can see the shares, so I must have something wrong with my target I'm guessing.

And yes the host name changes everytime another user logs on, however I'm the only user on this machine and it just stays running all the time.

No firewall that I know of except I'm using SME as a gateway mode.

And as far as file types go I have tried the ext3 since my linux box uses that files system, but I've also tried the others listed in the panel as well. No effect.

So i'm stumped and I don't really even know how to diagnose this. I think I'm going to plugin the usb drive and try that.
I hope I don't have to resort to command line mounts and things on that as well.
Anyhow thanks for the reply.

P.S yes I agree is sound like it should be simple and just work but perhaps linux desktop is changing things on my end. I may try to boot to windows and see if there is any effect there. Thanks again.

I keep trying to perform a test backup with just (root) listed in the backup selections.

That should be fine for a test, although the name root should not have brackets around it.

I realize the server manager page indicates to just put in the //computername/share and not all this //???/???/??? etc.

Yes, so stop trying variations that are not supported.
Only use //computername/share and as suggested make sure you can access that by connecting to it by other means eg using Windows My Network Places.

I've tried with and without passwords.

OK, so stop trying without a username and password, they are required so make sure you use a valid combination.


Do you have a Windows PC on the network eg Win2K or Win XP, that is ideally a member of the sme server domain ?

I suggest you try a test backup to that, making sure you add ALL the required data to the job configuration.
It should work if everything is done correctly, this is a well proven program.

If it does NOT work to a Windows PC, then you have a problem somewhere, most probably your job configuration syntax etc or the share is not accessible.

If it DOES work OK to a Windows PC, then the problem (when backing up to Linux) is with your Linux desktop machine and/or the configuration you use for the backup job, or perhaps the share is not accessible.

Eliminate some possibilities first by doing a backup to a Windows PC which is known to work OK.
