>From an embedded device, I'm trying to mount a samba share using SMB2, with the 'vers=2.1' mount option, but I don't seem to get it to work, so I was hoping somebody could maybe shed some light. mount -t cifs //192.168.0.1/networkshare /tmp/nas -o username=,password=,vers=2.1,nounix,noserverino,uid=123,gid=123,nobrl,file_mode=0770,dir_mode=0770,iocharset=utf8 mount: mounting //192.168.0.1/networkshare on /tmp/nas failed: Invalid argument Client: Embedded device with Linux 3.14 kernel, BusyBox version v1.20.2p3 I have enabled and built the embedded device's kernel with CONFIG_CIFS_SMB2. /proc/fs/cifs/DebugData: CIFS Version 2.02 Features: Active VFS Requests: 0 Servers: dmesg: <7>[ 3937.470000] fs/cifs/cifsfs.c: Devname: //192.168.0.1/networkshare flags: 32768 <7>[ 3937.470000] fs/cifs/connect.c: iocharset set to utf8 <7>[ 3937.470000] fs/cifs/connect.c: Anonymous login <7>[ 3937.470000] fs/cifs/connect.c: file mode: 0x1f8 dir mode: 0x1f8 <7>[ 3937.470000] fs/cifs/connect.c: CIFS VFS: in cifs_mount as Xid: 2 with uid: 0 <7>[ 3937.470000] fs/cifs/connect.c: UNC: \\192.168.0.1\networkshare <7>[ 3937.470000] fs/cifs/connect.c: Socket created <7>[ 3937.470000] fs/cifs/connect.c: sndbuf 16384 rcvbuf 87380 rcvtimeo 0x2bc <7>[ 3937.470000] fs/cifs/connect.c: CIFS VFS: in cifs_get_smb_ses as Xid: 3 with uid: 0 <7>[ 3937.470000] fs/cifs/connect.c: Existing smb sess not found <7>[ 3937.470000] fs/cifs/smb2pdu.c: Negotiate protocol <7>[ 3937.470000] fs/cifs/transport.c: Sending smb: smb_len=102 <7>[ 3937.470000] fs/cifs/connect.c: Demultiplex PID: 3359 <7>[ 3937.480000] fs/cifs/connect.c: RFC1002 header 0x49 <7>[ 3937.480000] fs/cifs/smb2misc.c: smb2_check_message length: 0x4d, smb_buf_length: 0x49 <7>[ 3937.480000] fs/cifs/smb2misc.c: SMB2 data length 0 offset 0 <7>[ 3937.480000] fs/cifs/smb2misc.c: SMB2 len 77 <7>[ 3937.480000] fs/cifs/transport.c: cifs_sync_mid_result: cmd=0 mid=0 state=4 <7>[ 3937.480000] fs/cifs/smb2maperror.c: Mapping SMB2 status code -1073741811 to POSIX err -22 <7>[ 3937.480000] fs/cifs/misc.c: Null buffer passed to cifs_small_buf_release <7>[ 3937.480000] fs/cifs/connect.c: CIFS VFS: leaving cifs_get_smb_ses (xid = 3) rc = -22 <7>[ 3937.480000] fs/cifs/connect.c: CIFS VFS: leaving cifs_mount (xid = 2) rc = -22 Server: Samba 3.6.6 on Debian Wheezy I do have the max protocol = SMB2 under my [global] section in my samba.conf, and have restarted samba. I've also tried to look at the communication over wireshark, and I do see several SMB Negotiate Protocol requests and responses, but in all of the requests there's just "Requested Dialects: Dialect: NT LM 0.12, and in all the responses same thing, Dialect Index:0 NT LM 0.12 - which, as far as I know corresponds to SMB version 1 (?), not the 2.1 version I was hoping for... I'm lost here. I thought this was all one needed to do. So, any thoughts, insights or ideas would make me very happy. Thanks you guys!
