#5456 On EL8, webmin 1.97 default configuration uses rc init commands instead of systemctl to start/stop Samba

[ChrisKKS]

On a fresh install of Oracle Linux 8, webmin 1.97 and samba 4.12, the webmin config uses the "service" command instead of systemctl. This causes attempts to restart the samba service to fail with the error:
Failed to restart Samba servers : /etc/rc.d/init.d/smb start failed

If you check Webmin's idea of the OS and version by running grep os_ /etc/webmin/config , what output do you get?

[ChrisKKS]

It looks correct as below:

$ grep os_ /etc/webmin/config
os_type=redhat-linux
os_version=8
real_os_type=Oracle Linux
real_os_version=

Just in case I did something accidental in the last install from messing with webmin and samba settings. Here are the config from a fresh OL8.3 ISO install, fresh samba and webmin install ( using webmin repo). Right after dnf install webmin, nothing configured yet.

/etc/webmin/samba/config
pdbedit=/usr/bin/pdbedit
list_printers_command=lpc status | grep "[A-z0-9]:" | sed -e 's/://g'
smbgroupedit=/usr/bin/smbgroupedit
samba_status_program=/usr/bin/smbstatus
samba_password_program=/usr/bin/smbpasswd
smb_passwd=/etc/samba/smbpasswd
name_server=/usr/sbin/nmbd
stop_cmd=/etc/rc.d/init.d/smb stop
sort_mode=0
swat_path=/usr/sbin/swat

run_from_inetd=0
smb_conf=/etc/samba/smb.conf
samba_server=/usr/sbin/smbd
dont_convert=-499
start_cmd=/etc/rc.d/init.d/smb start

grep os_ /etc/webmin/config
os_type=redhat-linux
os_version=8
real_os_type=Oracle Linux
real_os_version=

rpm -qa webmin samba
samba-4.12.3-14.el8_3.x86_64
webmin-1.973-1.noarch

Ok, looks like the real issue is that we're detecting the Oracle Linux version incorrectly. What does the /etc/oracle-release file contain on your system?

As a work-around, you can just adjust the commands in /etc/webmin/samba/config

Chris, what is the output of the following commands:

cat /etc/oracle-release 
car /etc/os-release

There was a bug in Webmin's OS detection that effected Oracle Linux. This will be fixed in future releases ..
