stopping and starting services
 

Hi everyone.

I have installed Red Hat 7.1 and i am studying for the Linux+ exam. I don't know much but i heard this exam is a basic level exam.

My book tells me that to stop and start a service you do the following:

#./dhcp stop
#./dhcp start

when i do it i get no such file or directory error

I am logged in as root

for dhcp, it should be:

/usr/sbin/dhcpd

And to enable it on startup, run this:

chkconfig --level 345 dhcpd on

Now, I don't why dhcpd can't be controlled by using the /sbin/service command (ie. service dhcpd start/stop/restart) or by /etc/init.d/dhcpd start/stop/restart) but most services can be controlled using the service command

# for xinetd
/sbin/service xinetd start/stop/restart

# for mysqld
/sbin/service xinetd start/stop/restart

# for httpd
/sbin/servie httpd start/stop/restart

Some services are xinetd controlled (not standalone services) and for this services, enabling them under the corresponding files in /etc/xinetd.d/ and then restart xinetd will make them accessible. Like for wu-ftpd, to enable, edit /etc/xinetd.d/wu-ftpd and set the the 'disable=yes' to 'disable=no' and then restart xinetd:

/sbin/service xinetd restart

Or, the easiest way is:

/sbin/chkconfig wu-ftpd on

no need to restart xinetd here. once an ftp connection is made, only then you should see an ftp daemon running.

Have you tried the full path to it ?? And usually the dhcp has a d at the end like this:

dhcpd stop or start

try this
 

the files you are trying are normally localted in /etc/rc.d/init.d/ folders
