Hi, i cannot mount cifs shares on a NAS,trying from two sles 10 sp4 boxes (kernel 2.6.16.60-0.93.1-smp, 64bit, cifs-mount-3.0.36-0.13.20.1). I know that i could one or two months ago. The command i issue is: ====================================== pc52974:~ # mount -t cifs //nas/idg-2 /mnt/idg-2/ -o username=bernd.lentes,workgroup=scidom,rw Password: mount error(22): Invalid argument Refer to the mount.cifs(8) manual page (e.g.man mount.cifs) # In my syslog appears (after echo 1 \> /proc/fs/cifs/cifsFYI to make the output more verbose): fs/cifs/cifsfs.c: Devname: //nas/idg-2 flags: 64 fs/cifs/connect.c: CIFS VFS: in cifs\_mount as Xid: 7 with uid: 0 fs/cifs/connect.c: Domain name set fs/cifs/connect.c: Username: bernd.lentes fs/cifs/connect.c: UNC: \ as\idg-2 ip: 146.107.8.8 fs/cifs/connect.c: Existing tcp session with server found fs/cifs/connect.c: Existing smb sess found (status=1) fs/cifs/connect.c: file mode: 0x7f7 dir mode: 0x1ff fs/cifs/transport.c: For smb\_command 117 fs/cifs/transport.c: Sending smb of length 74 fs/cifs/connect.c: rfc1002 length 0x42 fs/cifs/connect.c: disk share connection fs/cifs/connect.c: Tcon flags: 0x1 fs/cifs/connect.c: CIFS Tcon rc = 0 fs/cifs/cifssmb.c: In QFSDeviceInfo fs/cifs/transport.c: For smb\_command 50 fs/cifs/transport.c: Sending smb of length 68 fs/cifs/connect.c: rfc1002 length 0x44 fs/cifs/cifssmb.c: In QFSAttributeInfo fs/cifs/transport.c: For smb\_command 50 fs/cifs/transport.c: Sending smb of length 68 fs/cifs/connect.c: rfc1002 length 0x50 fs/cifs/cifssmb.c: In GetSrvInodeNum for fs/cifs/transport.c: For smb\_command 50 fs/cifs/transport.c: Sending smb of length 74 fs/cifs/connect.c: rfc1002 length 0x27 fs/cifs/connect.c: invalid transact2 word count fs/cifs/netmisc.c: !!Mapping smb error code 87 to POSIX err -22 !! fs/cifs/cifssmb.c: error -22 in QueryInternalInfo fs/cifs/connect.c: CIFS VFS: leaving cifs\_mount (xid = 7) rc = -22 CIFS VFS: cifs\_mount failed w/return code = -22 Trying the same from a SLES 10 SP2 box works fine. Any ideas ? Bernd ---

This output does not seem to differ from what you already posted here. You used IP address this time, though. What could be more helpful is the output from the SP2 machine. And see how the lines differ. If it really worked with SP2, you could compare the /etc/nsswitch.conf , /etc/hosts files from the SP2 and SP4 boxes. If it really worked with SP4 1-2 months ago, I’d check if cifs-mounts package changed in the last months (rpm -q --last) and how (rpm -q --changelog cifs-mounts) and if that’s relevant. But it may be the kernel, though… (I had a long battle with Samba last week, where on a day, a valid samba configuration stopped working. Krb5 seemed to be guilty, and although I hate using not core SLES software, installed the krb5 package from opensuse 11.4 which fixed everything. So somethimes we must hack, unfortunately.) But a packet capture with tcpdump could be more useful. Again, both SP2 and SP4, and see where it goes wrong. ---
