11.5 Troubleshooting utilities on AIX

This section describes AIX tools for troubleshooting SMB protocol. SMB is

not a native protocol on AIX, so special utilities are not available, but you can

still get valuable information from standard TCP/IP tools.

11.5.1 TCP/IP configuration checking

You can check the TCP/IP configuration on SMB server with the following

standard utilities:

• ifconfig

• ping

• arp

• netstat

• route

• nslookup

11.5.2 Fast Connect for AIX server troubleshooting

The following sections describe commands that may help you determine what

the trouble is with your server.

11.5.2.1 The Fast Connect for AIX server net command

The command line administration program is the

net command. This

command has a syntax similar to the one you have with Windows systems.

The most important options for troubleshooting are:

• help [ command ]

This shows the list of main options or a description of an individual option

of the

net command.

• status

This shows the server state (see Figure 100 on page 172) and the server

NetBIOS and TCP/IP name:

• statistics [/reset]

This shows statistics of the server’s sessions, connections, and errors

since the last server start or the last reset of the statistics (option /reset).

You should be careful about resetting statistics because you could get

less information from net statistics. You can solve this by doing /reset

when there is no client connected to the server. You can see additional

information about statistics analyzed in Appendix 11.5.2.2, “net statistics

command” on page 183.

• user

Show and change user settings. User manipulation is only necessary

when you use Fast Connect for AIX authentication. Important options are:

net user [password|-p] [/add] [/active:[0|1]] /changeaixpwd:[yes|no]

Add a user with the specified password and/or (de)activate one. You

cannot add a user that is not also an AIX user. If you select -p, you are

prompted for the password, and the password is not displayed on the

screen. Like all the other changes operated with the

net command, only

root can change the password of the user. If you want to change both the

AIX and Fast Connect for AIX password at the same time, you can use the

/changeaixpwd:yes option.

• nbstatus

This shows the status of NBNS (running or not running).

• nblistnames

This lists NetBIOS names from the NetBIOS name table.

$ net status

11.5.2.2 net statistics command

You can quickly check for SMB protocol problems with the

net statistics

command. Output from this command looks like this:

You can see the server name, server startup time, and statistics startup time

in the header. Then, you can see the following values:

Sessions started This counts the number of sessions initiated from the

clients.

Sessions timed out This counts the number of sessions that were

disconnected because of inactivity time (related to the

autodisconnect parameter).

Sessions dropped This counts the number of sessions that ended - with

or without error.

Password Errors This counts the number of errors because of illegal

passwords. It is not necessarily a serious matter if this

number is not zero. Maybe a guest account was used

or somebody simply mistyped a password. The first

step is for the client to send the user’s name and

password, which can be rejected (thus the error), and

then request guest account, which is accepted.

Permission Errors This counts the number of file permission errors.

Print jobs queued This counts the number of jobs submitted to printer

queues.

You can continuously watch net statistics output if you enter:

clear; while (true); do tput home; net statistics; sleep 2; done
