How can I log samba events?

You'll typically see the offending call at the end of the trace, just before the program terminates. The manual page also lists all the other capabilities such as windbind and passwd. And of course, there are several ways to accomplish the same task.
If you want date and hour, you have to capture the line before the one with actual information. Next, you just need to restart the samba services. Setting the Log File Name Samba logs events to the file set in the log file parameter.
server - However, setting a higher log level causes Samba to log all events on the higher level, what can result in large log files. The samba version is 3.
Contents: Samba is extremely robust. Once you've got everything set up the way you want, you'll probably forget that it is running. When trouble occurs, it's typically during installation or when you're trying to add something new to the server. Fortunately, there are a wide variety of resources that you can use to diagnose these troubles. While we can't describe in detail the solution to every problem that you might encounter, you should be able to get a good start at a resolution by following the advice given in this chapter. The first section of the chapter lists the samba login bag, a collection of tools available for troubleshooting Samba; the second section is a detailed how-to, and the last section lists extra resources you may need to track down particularly stubborn problems. Sometimes Unix seems to be made up of a handful of applications and tools. There are tools to troubleshoot tools. And of course, there are several ways to accomplish the same task. Your first line of attack should always be to check the log files. The Samba log files can help diagnose the vast majority of the problems that beginning to intermediate Samba administrators are likely to face. Samba is quite flexible when it comes to logging. You can set up the server to log as little or as much as you want. Substitution variables that allow you to isolate individual logs for each machine, share, or combination thereof. As we mentioned in Chapter 4, Disk Sharesyou can override the samba login and name using the log file configuration option in smb. For example, let's assume that we are going to use a Windows client to browse a directory on a Samba server. Usually you won't need any more than level 3; this is more than adequate for most Samba administrators. Levels above 3 are for use by the developers and dump enormous amounts of cryptic information. Here is example output at levels 2 and 3 for the same operation. However, you should be aware that log levels above 3 will quickly fill your disk with megabytes of excruciating detail concerning Samba internal operations. Log level 3 is extremely useful for following exactly what the server is doing, and most of the time it will be obvious where an error is occurring by glancing through the log file. A word of warning: using a high log level 3 or samba login will seriously slow down the Samba server. Remember that every log message generated causes a write to disk an inherently slow operation and log levels greater than 2 produce massive amounts of data. Essentially, you should turn on logging level 3 only when you're actively tracking a samba login in the Samba server. Then, you can either restart Samba, or force the current daemon to reprocess the configuration file. Now all you have to do is create an smb. Similarly, if only particular users are experiencing a problem, and it travels from machine to machine with them, you can isolate logging to a specific user by adding the following to the smb. The trace command masquerades under several different names, depending on the operating system that you are using. All have essentially the same function, which is to display each operating system function call as it is executed. This allows you to follow the execution of a program, such as the Samba server, and will often pinpoint the exact call that is causing the difficulty. One problem that trace can highlight is the location of an incorrect version samba login a dynamically linked library. This can happen if you've downloaded prebuilt binaries of Samba. You'll typically see the offending call at the end of the trace, just before the program terminates. A sample strace output for the Linux operating system follows. This is samba login small section of a larger file created during the opening of samba login directory on the Samba server. Each line is a system-call name, and includes its parameters and the return value. If there was an error, the error value e. You can look up the parameter types and the errors that can occur in the appropriate trace manual page for the operating system that you are using. You don't have to be a expert to see that the file desktop. In fact, many difficult problems can be identified by looking for obvious, repeatable errors with trace. Often, you need not look farther than the last message before a crash. The tcpdump program, written by Van Jacobson, Craig Leres, and Steven McCanne, and extended by Andrew Tridgell, allows you to monitor network traffic in real time. A variety of output formats are available and you can filter the output to look at only a particular type of traffic. A sample tcpdump log follows. The options we used were -v verbose-i eth0 to tell tcpdump the interface to listen on an Ethernet portand -s 255 to tell it to save the first 255 bytes of each packet instead of the default: the first 68. The option port not telnet is used to avoid screens of telnet traffic, since we were logged in to the server remotely. The tcpdump program actually has quite a number of options to filter just the traffic you want to look at. If you've used snoop or etherdump, they'll look vaguely familiar.

During the log file is rotated, Samba overrides a previously archived version of the log file. Fortunately, there are a wide variety of resources that you can use to diagnose these troubles. I believe Samba is configured like that by default, here are the relevant lines in smb. I am using Linux mate at the server, all the latest updates. While we can't describe in detail the solution to every problem that you might encounter, you should be able to get a good start at a resolution by following the advice given in this chapter. To learn more, see our. Note that this is not a complete list. I'm guessing I am missing something within the config somewhere. To store all logs on a centralized server, set up a centralized syslog server, configure Samba to log to the syslog daemon, and configure the syslog daemon to send the logs to the centralized server. With that, I am able to see the shares and the server from the network, but it says that Windows cannot access them.
