NAME

na_cifs_sessions - information on current CIFS activity

SYNOPSIS

The cifs sessions command displays information about CIFS users who are connected to the filer. If you omit the argument, the command displays a summary of information about the filer and lists the users who are connected to the filer. It is also possible to ask for session information by specifying the user's machine_name. One can always specify the user's client machine_IP_address to the cifs sessions command. However, if the filer has not been provided the machine name and session information is asked for using the machine_name argument, the cifs sessions command will fail with the message "User (or PC) not logged in". The -p option filters sessions based on the version of the SMB protocol used. When the -p option is used with `smb' as the argument, only SMB 1.0 sessions are displayed. When the -p option is used with `smb2' as the argument, only SMB 2.0 sessions are displayed. When the -p option is not used, both SMB 1.0 and SMB 2.0 sessions are displayed. The -p option can be used along with -c and -s options. The -i option filters the sessions on the basis of the IP protocol used. When -i option is used with `ipv4' as the argument, only sessions established over IPv4 protocol are displayed. When -i option is used with `ipv6' as the argument, only sessions established over IPv6 protocol are displayed. When -i option is not used, all the sessions established over IPv4 and IPv6 are displayed. The -i option can be used along with -c and -s options. The -t option displays the total count of CIFS sessions, open shares and open files. The -c option displays information about open directories and the number of active ChangeNotify requests. When used with the -t option, the total count of open directories and active ChangeNotify requests is also shown. When no other option or argument is present, the -c option shows, for each user, the number of open directories and number of active ChangeNotify requests. A CIFS client connected to the filer is displayed under the PC IP (PC Name) column as an IP address followed by a NetBIOS name (if available) within parentheses. If NetBIOS name is unavailable, the name is displayed as an IP address followed by empty parentheses.

EXAMPLES

If you include the user argument, the command displays information about the specified user, along with the names and access level of files that user has opened. If you use * as the specified user, the command lists all users. Executing the command for user sam might produce output as follows:

cifs sessions sam users shares/files opened 172.18.34.11(HAWLEY-HOME1) (sam) ENG-USERS Read-denyW - \SAM\SRC\TEST\test_pgm.c 132.170.108.1(HAWLEY-PC) (sam) ENG-USERS

Specifying the -c option with a user argument, will display the names of open directories and the number of active ChangeNotify requests against the directory.

cifs sessions -c sam users shares/files and directories opened 172.18.34.11(HAWLEY-HOME1) (sam) (using security signatures) ENG-USERS Read-denyW - \SAM\SRC\TEST\test_pgm.c 2 ChgNfys - \SAM\SRC\TEST

The -s option displays security information for a specified connected user. If you do not specify a user or workstation name, the command displays security information for all users. Executing the command with -s * might produce the following:

cifs sessions -s * users Security Information WIN-95 (AGuest - nobody[guest]) *************** UNIX uid = 1208 user is a member of group nobody(65535) NT membership NT-DOMAIN\Domain Guests BUILTIN\Guests User is also a member of Everyone, Network Users ***************
Here are examples using the machine_name and machine_IP_address arguments:
