When attempting to use smblcien to talk to (some) Windows shares it fails to list files with the dir command. smb: \> dir STATUS_NO_MORE_FILES listing \* 51200 blocks of size 8192. 37379 blocks available smb: \> cd settings smb: \settings\> dir STATUS_NO_MORE_FILES listing \settings\* 51200 blocks of size 8192. 37379 blocks available This is seen with Windows servers which report: OS=[EMC-SNAS:T5.4.21.400] Server=[NT1] on connexion. A debug level 5 trace reports: Doing spnego session setup (blob length=16) server didn't supply a full spnego negprot The problem does not occur on other CIFS servers which report: OS=[Windows 5.0] Server=[Windows 2000 LAN Manager] FWIW - the smbclient from v2.2.8a can connect (same connect string) to and list the dirs which fail with 3.0.22.
