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 ...
Samba Domain Controller do not support network browsing, and thus no nmbd processes are listed. |
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
