Samba mount fail on cifs

  • 772

Client Debian, server Windows 2019.
Even that DNS resolved ok, I added eagleeye on /etc/hosts, also modified /etc/samba.smb.conf adding:

   client min protocol = SMB2
   client max protocol = SMB3

I can browse the share with smbclient:

#> smbclient  -V
Version 4.2.14-Debian

#> smbclient -L eagleeye -Uuuu%ppp -Wdom
Domain=[DOM] OS=[] Server=[]

        Sharename       Type      Comment
        ---------       ----      -------
        ADMIN$          Disk      Remote Admin
        C$              Disk      Default share
        IPC$            IPC       Remote IPC
        ...
        Repo            Disk

#> smbclient  //eagleeye/repo -Uusername%admin -Wdom

however, I can't mount as a share as 

mount -t cifs //eagleeye/repo ~/share
mount: wrong fs type, bad option, bad superblock on //eagleeye/repo,
       missing codepage or helper program, or other error
       (for several filesystems (e.g. nfs, cifs) you might
       need a /sbin/mount.<type> helper program)

       In some cases useful info is found in syslog - try
       dmesg | tail or so.

#> lsmod | grep cifs

  1. Dunno about Debian, but on CentOS mount.cifsuses SMB1 by default, so you must use the vers option to force SMB2/3: mount -t cifs -o vers=2.0 //eagleeye/repo ~/share Other possible values on CentOS: 2.1, 3.0.
