Services

Services on Ubuntu are managed in a broadly similar way to those on Red Hat.

Graphical Tools

Services can be configured by clicking System -> Administration -> Services. A tool called Boot-Up Manager is also available.

Command Line Tools

Below is a table of example commands for managing services. The apache/httpd service is used as an example.
Task
Red Hat / Fedora
Ubuntu
Ubuntu
(with sysv-rc-conf or sysvconfig)
Starting/stopping services immediately
service httpd start
invoke-rc.d apache start
service apache start
Enabling a service at boot
chkconfig httpd on
update-rc.d apache defaults
sysv-rc-conf apache on
Disabling a service at boot
chkconfig httpd off
update-rc.d apache purge
sysv-rc-conf apache off
Note: Whereas Red Hat and Fedora servers boot into runlevel 3 by default, Ubuntu servers default to runlevel 2.
Note: The service and invoke-rc.d commands call init scripts to do the actual work. You can also start and stop services by doing e.g. /etc/init.d/apache start on Ubuntu, or /etc/init.d/httpd start on Red Hat/Fedora.

Network

Graphical Tools


Fedora/RHEL have system-config-network, ubuntu pre 10.04 had gnome-nettool to edit static ip address, since 10.04 nm-connection-editor is the best choice. For Ubuntu 10.04 Studio there is only manual editing of files since NetworkMontor is not included

NFS mount add in fstab _netdev instead of default | firewall-cmd --list-all

By OK -
Redhat recommends us to add  _netdev  option for NFS file system in /etc/fstab. So that they can be mounted after starting the networking service. Alternative ways to refer to partitions: Label : LABEL=label Network ID Samba : //server/share NFS : server:/share SSHFS : sshfs#user@server:/share Device : /dev/sdxy (not recommended) Example #1 //192.168.1.134/share_name /mnt/share_name cifs username=server_user,password=server_password,_netdev 0 0 ^ Path to your share ^ Mountpoint ^ Username ^ Password ^ See note A Note A: The  _netdev  options makes sure the mount is only attempted AFTER a network connection has been established. Example #2 10.10.10.1:/vol1/fs1 /data nfs defaults,_netdev 0 0 ============================ [root@localhost ~]# firewall-cmd --list-all public   target: default   icmp-block-inversion: no   interfaces:   sources:   services: dhcpv6-client high-availabi...
