Older Axis IP cams & SMB1 issues...



  • Anyone have any experience with older Axis cams running firmware that only allows you to mount shares via SMB1?

    I can't seem to get any of my old Axis cameras to mount shares on my SAMBA server running Ubuntu 18.04. I found this little tidbit from Axis: https://www.axis.com/support/faq/FAQ116392

    The cameras in question are indeed running firmware that is before 5.90. So according to that Axis FAQ, they should only support SMB1. But they do not connect to a default smb.conf file. Did SAMBA remove support for SMB1 by default?

    I've tried adding to the smb.conf file

    server min protocol = NT1
    client min protocol = NT1
    

    However, the cameras still won't connect. The errors I'm getting for on the camera logs themselves are:

    <CRITICAL> Nov 10 16:55:04 axis-00408cdbbd05 kernel: [72008.090000] CIFS VFS: Send error in SessSetup = -13
    <CRITICAL> Nov 10 16:55:04 axis-00408cdbbd05 kernel: [72008.210000] CIFS VFS: Send error in SessSetup = -13
    <WARNING > Nov 10 16:55:04 axis-00408cdbbd05 disks[1133]: mount_disks.c : Disk 'NetworkShare0' NOT mounted (due to error) (4)
    

    I'm wondering if its the SAMBA server itself that simply isn't honoring a SMB1 connection. Is there a trick to making sure that SMB1 is still being supported on Linux/SAMBA for legacy devices?



  • Yes, enabling SMB1 on Samba would be manual, there is a setting for that that we will have to dig out.

    Any chance you can update the firmware on the Axis cameras?



  • try this...

    Find the [global] section and append the following line:

    min protocol = SMB1


  • Scott,

    Unfortunately these cams are so old that Axis doesn’t update them anymore accept for security fixes. So I doubt these will ever get SMB2+.

    I tried min protocol SMB1 before but got an error from testparm that says “unknown parameter” or something of the sort. So that’s when I also tried “NT1” as according to the SAMBA man page, NT1 seems to be the level right below SMB2. But that also doesn’t work either... Strange.

    Except SMB 1 is a security issue.

  • @JaredBusch

    Well sure but they can’t actually turn off SMB on an IP camera...



  • @scottalanmiller said in Older Axis IP cams & SMB1 issues...:

    try this...

    Find the [global] section and append the following line:

    min protocol = SMB1
    

    @biggen I believe it should be max protocol = SMB1



  • Any luck?



  • Actually I wonder if needs to be NT1 instead of SMB1



  • @Reid-Cooper

    Unfortunately no. Not at all.

    max protocol = SMB1
    

    Does not work. I think they changed it to “NT1” at some point.

    But even with NT1, the cameras still won’t connect. I know the SAMBA server is working as I can use the same username/pass and connect via a Win10 box.

    I’ve got a ticket open with Axis. It’s aggravating because they all used to work on an older Ubuntu 14 server a few years ago before they were temporarily shelved. Now that I’m bringing these old camera back to life, the SMB landscape has changed and stuff that worked once with ease has turned into a headache.



  • @biggen Can you post your full smb.conf file



  • @Romo

    Sure. Its pretty bare bones. Its basically a default smb.conf file with only a single share I added to the end.

    I tried min protocol = NT1 and max protocol = NT1 which I believe are SMB1. Neither allowed the cams to connect. I verified that the server was actually using NT1 by using a Windows client and connected to the samba share. I then used smbstatus to verify my windows box connected to the share via the NT1/SMB1 protocol.

    I'm at a bit of a loss. There is something hampering the communication between these old cams and my samba server. They are on the same subnet so I can rule out any weird routing configuration.



  • So I think I "may" have fixed it. I upped the logging level in Samba and noticed that it was a NTLM auth problem.

    So I added ntlm auth = yes which allows NTLMv1 clients to connect in the smb.conf file.

    SAMBA 4.5 changed the default method of NTLM to NTLMv2 clients only. Older clients that don't use NTLMv2 can't connect without changing this setting.

    What a PITA that was to diagnose.
