Hi, I have a problem with users losing their connections from linux clients with cifs share. (Windows 2008) :CIFS VFS: Unexpected SMB signature I am using two methods for mounting: pam_mount and autofs, both with same results. I am using mount options nounix,noserverino I am lauching cifs module on boot (rc.local) with modprobe cifs echo 0 > /proc/fs/cifs/OplockEnabled echo 1 > /proc/fs/cifs/MultiuserMount echo 7 > /proc/fs/cifs/cifsFYI What happens : in /var/log/messages ===================== Dec 3 17:31:01 u1205-08l kernel: [ 3732.140040] CIFS VFS: Unexpected lookup error -512 Dec 3 17:31:01 u1205-08l kernel: [ 3732.334939] CIFS VFS: Unexpected SMB signature This user was working since one hour with no problem : Daemon log : ============= Dec 3 16:29:35 u1205-08l cifs.upcall: key description: cifs.spnego;0;0;3f000000 ;ver=0x2;host=figue;ip4=130.120.8.11;sec=krb5;uid=0x1000005;creduid=0x1000005;us er=21206xxx;pid=0x65f Dec 3 16:29:35 u1205-08l cifs.upcall: ver=2 Dec 3 16:29:35 u1205-08l cifs.upcall: host=figue Dec 3 16:29:35 u1205-08l cifs.upcall: ip=130.120.8.11 Dec 3 16:29:35 u1205-08l cifs.upcall: sec=1 Dec 3 16:29:35 u1205-08l cifs.upcall: uid=16777221 Dec 3 16:29:35 u1205-08l cifs.upcall: creduid=16777221 Dec 3 16:29:35 u1205-08l cifs.upcall: user=21206xxx Dec 3 16:29:35 u1205-08l cifs.upcall: pid=1631 Dec 3 16:29:35 u1205-08l cifs.upcall: find_krb5_cc: considering /tmp/krb5cc_167 77221 Dec 3 16:29:35 u1205-08l cifs.upcall: find_krb5_cc: FILE:/tmp/krb5cc_16777221 i s valid ccache in dmesg ========= fs/cifs/inode.c: Getting info on \21206xxx\TP9 [ 3735.419612] fs/cifs/transport.c: For smb_command 50 [ 3735.419615] fs/cifs/transport.c: Sending smb: total_len 104 [ 3735.420257] fs/cifs/connect.c: RFC1002 header 0x23 [ 3735.420261] fs/cifs/connect.c: invalid transact2 word count [ 3735.422403] fs/cifs/transport.c: cifs_sync_mid_result: cmd=50 mid=37012 state=4 [ 3735.422406] CIFS VFS: Unexpected SMB signature [ 3735.422408] Status code returned 0xc0000022 NT_STATUS_ACCESS_DENIED [ 3735.422411] fs/cifs/netmisc.c: Mapping smb error code 0xc0000022 to POSIX err -13 [ 3735.422413] fs/cifs/cifssmb.c: Send error in QPathInfo = -13 [ 3735.422415] fs/cifs/dir.c: CIFS VFS: leaving cifs_lookup (xid = 76854) rc = -13 [ 3735.422424] fs/cifs/dir.c: CIFS VFS: in cifs_lookup as Xid: 76855 with uid: 16777221 [ 3735.422427] fs/cifs/dir.c: parent inode = 0xf14481f0 name is: TP9 and dentry = 0xf074e300 [ 3735.422429] fs/cifs/dir.c: NULL inode in lookup [ 3735.422430] fs/cifs/dir.c: Full path: \21206xxx\TP9 inode = 0x (null) I don't understand what happens... NULL inode in lookup ... What about noserverino option ? Perhaps an unresponsive server... The network infrastructure is old. Last year I got this working very well, but the server was in a better place (switch and network infrastructure speaking) Regards, Thanks in advance Serge Conrad Une messagerie gratuite, garantie à vie et des services en plus, ça vous tente ?
