Troubleshooting the SMB Client

The following are troubleshooting issues for the Oracle Solaris SMB client. For related troubleshooting information, see the following:

Viewing SMB Client Property Settings

The Oracle Solaris SMB client configuration uses the sharectl command to set properties. Before you change property values, view the current property settings by running the sharectl get smbfs command.

Access Denied Message When Accessing a Server

You get an Access Denied error when attempting to access or view SMB shares from a server. This problem might occur because the password you supplied is wrong or the SMB server is part of a domain.

If the SMB server is part of a domain, you must provide the domain name for the smbadm show-shares or mount command. Otherwise, the server assumes that you are attempting to authenticate a local user, and the authentication process fails.

For example, if the server solarsystem is in the MYDOMAIN domain, the following commands would be appropriate to view and access SMB shares as user cal:

# smbadm show-shares -c cal "//MYDOMAIN@solarsystem"
# mount -F smbfs "//MYDOMAIN;cal@solarsystem/tmp" /mnt

Cannot View or Mount SMB Shares

If you are unable to view or mount SMB shares, use the smbadm show-shares [-A | -u username] [-t] server command. The -A option gives anonymous access to the server if the server permits such access.

Cannot Mount SMB Shares as a Regular User

You might see the following error message when you attempt to mount an SMB share as a regular user on a mount point that you own:

$ mount -F smbfs //username@server-name/share-name mount-point
mount: mount_smbfs: mount-point: Not owner

Verify that you have the following entries in your /etc/security/exec_attr file:

Basic Solaris  User:solaris:cmd:::/usr/lib/fs/smbfs/mount:privs=sys_mount
Basic Solaris User:solaris:cmd:::/usr/lib/fs/smbfs/umount:privs=sys_mount

These entries in the /etc/security/exec_attr file enable you to mount and unmount SMB shares on mount points that you own as a regular user.

`tar` and `gtar` Warnings

You might see the file changed as we read it warning in the following situations:

When you use the Oracle Solaris SMB client to mount an SMB share, and use the gtar utility to write the share to a tape
When you use the Oracle Solaris SMB client to mount an SMB share, and use the tar utility checks file attributes after setting them

Other than these warnings, the tar and gtar operations succeed as expected.

You can ignore these warnings.

Note - smbfs ignores calls to set any file or directory attributes, as those have no direct representation in SMB. Also, smbfs does not support the “UNIX extensions” that would permit the storing of attributes with some servers.

Viewing XATTR Status for Mounted Shares

By default, shares that are mounted by the mount_smbfs command enable Oracle Solaris extended attributes by setting the xattr mount option. However, if the SMB server does not support Windows named streams, shares mounted by mount_smbfs set the noxattr mount option.

To verify whether the xattr or noxattr mount option is used, do the following:

$ mount -v | grep 'type smbfs'

The following example shows that the share mounted on /mnt has xattr set, while the share mounted on /tmp has noxattr set:

$ mount -v | grep 'type smbfs'
//root@solarsystem/tmp on /mnt type smbfs   
  remote/read/write/setuid/devices/intr/xattr/dev=5080000 on Tue Jun  5 18:20:48 2012
//root@pluto/files on /files type smbfs
 remote/read/write/setuid/devices/intr/noxattr/dev=4800000 on Mon Jun  4 11:37:26 2012
