rename reboot command

coco03 · 04-18-2005, 08:20 AM

Hi,

for security reasons, I would like to rename the "reboot" command.
I have renamed "reboot" ---> "reboot_server"

But this command is a symbolic link to "halt" and if I execute "reboot_server", the server only shutdown and don't reboot.

How to make the "reboot_server" command doing the same as "reboot" command ??

Thanks
Charlie

Hi,

If you want to do some security settings, look at /etc/pam.d/reboot.

If you want to create the new link that do the same thing like something in /sbin/, Look at Fedora solution. They are using pair of links in /sbin and /usr/bin directory.

see man consolehelper

I think it might be easier to create an alia for the command. In the login profile, .bashrc, you may see alises listed which get invoked at boot time. Redhat used to have an alias of rm to rm -i for root, which would force a response as files were about to be removed. You could do something similar. The syntax is something like alias reboot='reboot_server'. I think aliases are one of the best features of the Unix, and linux environments. They shopuld probably be used a lot more.

while aliases are very helpful, i think that the original poster does not want "reboot" as a command to be used at all, so an alias is not the way to go for this one.

Thanks for your help,

I have renamed : reboot -->reboot_server, halt --> halt_server and shutdown --> shutdown_server

then I have used aliases :

alias reboot_server='shutdown_server -r now'
alias reboot='echo "type reboot_server if you are shure you want to reboot the server" '

And it works

I don't understand how this is any more secure.

It is more secure because all engineer of my compagny are connected with ssh to there own linux computer and to servers.
Sometimes, someone reboot a server instead of its computer.
Now, in order to reboot a server you have to type "reboot_serverXXX", and the "reboot" command is disable.
