From: jackie on 6 May 2010 04:00 Hello :-), I have some problem with the cifs client of linux. I can't mount a volume from a Windows 7 machine with NTLMv2 authentication. e.g. # mount -t cifs //win7-box/C\$ mount-point --verbose -o sec=ntlmv2,credentials=smb-passwd mount error(22): Invalid argument Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) #dmesg | tail Status code returned 0xc000000d NT_STATUS_INVALID_PARAMETER fs/cifs/netmisc.c: Mapping smb error code 87 to POSIX err -22 fs/cifs/misc.c: Null buffer passed to cifs_small_buf_release fs/cifs/sess.c: ssetup rc from sendrecv2 is -22 fs/cifs/sess.c: ssetup freeing small buf ffff8800437a6000 CIFS VFS: Send error in SessSetup = -22 fs/cifs/connect.c: CIFS VFS: leaving cifs_mount (xid = 132325) rc = -22 CIFS VFS: cifs_mount failed w/return code = -22 I'm pretty sure NTLMv2 is enabled on the Windows 7 machine and it is the only allowed authentication method. I was able to mount a volume from a XP machine (configured to authenticated by NTLMv2 only) with the same parameters. However, smbclient works just fine. (the below command works) # smbclient //win7-box/C\$ -A smb-passwd The kernel is linux 2.6.33, I'm using the cifs driver bundled with it. # cat /proc/fs/cifs/DebugData Display Internal CIFS Data Structures for Debugging --------------------------------------------------- CIFS Version 1.62 Active VFS Requests: 40 Servers: I saw many people on the web suggest to configure Windows 7 to use other authentication methods such as NTLM or LANMAN, but it actually fixed nothing. (https doesn't work, so you should use http?) There is no domain, it is mounted by peer to peer method. Do I miss something? How can I use sec=ntlmv2 with Win7? I'm sorry for my poor English... -- Kai-Chieh Ku -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba |
