Failure to mount a built-in SMB/CIFS server in a router I have a router that supports a smb/CIFS server that exports a FAT32 filesystem on a USB storage that is plugged into its USB port. (IODATA WN-AC1167DGR) Windows 7 64 bit can mount the FAT32 file system in a USB memory stick. I can mount it from the window's explorer with user/password. However, when I tried to mount it from linux by mount.cifs, I failed. More details. The SMB/CIFS server in the router expots a share name "Drive(A1)" I learned this from the mounting of this SMB/CIFS server by Windows 7 64-bit PC. Also, I can dump the following using smbclient from the same linux PC (actually a virtualbox guest on the said Windows 7 host). $ smbclient -L AIRPORT51712 --ip-address=192.168.0.201 --user=admin Enter admin's password: Domain=[WORKGROUP] OS=[Linux 2.6.33] Server=[SXLM1.0.7beta1.iodata] Sharename Type Comment --------- ---- ------- IPC$ IPC Drive(A1) Disk USB Storage Device (Flash/Drive UT_USB20) Domain=[WORKGROUP] OS=[Linux 2.6.33] Server=[SXLM1.0.7beta1.iodata] Server Comment --------- ------- Workgroup Master --------- ------- I notice that the router runs an old/stable version of linux. Strange thing is that if I don't specify the hostname of the server "AIRPORT51712" that is assigned in the router SMB/CIFS setup to smbclient command, I get the following error. $ smbclient -L --ip-address=192.168.0.201 --user=admin Enter admin's password: Connection to --ip-address=192.168.0.201 failed (Error NT_STATUS_UNSUCCESSFUL) $ Anyway, mount.cifs failed thusly: # mount.cifs "//192.168.0.201/Drive(A1)" /tmp/L-temp -o username=admin,noperm Password for admin@//192.168.0.201/Drive(A1): ************ mount error(22): Invalid argument Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) And at the end of dmesg I got: [92588.526403] Key type dns_resolver registered [92588.559363] FS-Cache: Netfs 'cifs' registered for caching [92588.560391] Key type cifs.spnego registered [92588.560406] Key type cifs.idmap registered [92588.651527] CIFS VFS: bad security blob length 188 [92588.651532] CIFS VFS: Send error in SessSetup = -22 [92588.651772] CIFS VFS: cifs_mount failed w/return code = -22 So it seems that there is an authentication error due to unexpected blog length (?). Since windows 7 64-bit can mount the share "Drive(A1)" and smbclient prints the share information, the smb/cifs server function of the router seems to work more or less. I wonder why mount.cifs failed. I searched the web, but could not find the particular message "CIFS VFS: bad security blob length 188". That is the particular length 188 does not show up quickly. Any ideas?
