Introduction

This documentation helps you to troubleshoot problems users can encounter when running Samba as an Active Directory (AD) domain controller (DC).



General

Setting the Samba Log Level

For details, see Setting the Samba Log Level.


The net Command Fails to Connect to the 127.0.0.1 IP Address

For details, see Troubleshooting Samba Domain Members - The net Command Fails to Connect to the 127.0.0.1 IP Address.



Process Management

Verifying That Samba Is Running

Use the ps utility to verify that Samba processes are executed:

# ps axf | egrep "samba|smbd|winbindd"
...
917 ?        Ss     0:00 /usr/local/samba/sbin/samba -D
923 ?        S      0:00  \_ /usr/local/samba/sbin/samba -D
936 ?        Ss     0:00  |   \_ /usr/local/samba/sbin/smbd -D --option=server role check:inhibit=yes --foreground
940 ?        S      0:00  |       \_ /usr/local/samba/sbin/smbd -D --option=server role check:inhibit=yes --foreground
941 ?        S      0:00  |       \_ /usr/local/samba/sbin/smbd -D --option=server role check:inhibit=yes --foreground
943 ?        S      0:00  |       \_ /usr/local/samba/sbin/smbd -D --option=server role check:inhibit=yes --foreground
924 ?        S      0:00  \_ /usr/local/samba/sbin/samba -D
925 ?        S      0:00  \_ /usr/local/samba/sbin/samba -D
...
935 ?        Ss     0:00  |   \_ /usr/local/samba/sbin/winbindd -D --option=server role check:inhibit=yes --foreground
939 ?        S      0:00  |       \_ /usr/local/samba/sbin/winbindd -D --option=server role check:inhibit=yes --foreground
...

All samba, smbd, and winbindd processes must be child processes of one samba process.

If you do not see a process structure as displayed:

  • Verify your Samba log files to locate the problem. For a detailed output, increase the log level. For details, see Setting the Samba Log Level
  • Start Samba interactively and watch the output:
# samba -i



DNS

Updating

If you have any problems with your Active Directory (AD) domain controller (DC) after updating Samba, see: Notable Enhancements and Changes.
