temp hostname change

rleon — Mon, 01 Aug 2011 16:05:15 GMT

We have an app team that insist that they need to change a hostname to install their app.

Its just as simple as running the hostname command no neeed to edit /etc/password , /etc/rc.config.d/netconf ..

Needless to say their change occur in the middle of the night ... and then once they are done we are to change the hostname back.

We tried to change the varible HOSTNAME but when the hostname command is ran it still shows the old hostname.

My question is .. is there a varible to change the hostname?

Or would we have to give them sudo access to change the hostname back and fourth.

why not just modify dns and/or /etc/hosts to add an additional name?

Try

# hostname

# hostname mynewhostname

# hostname

Giving sudo access to change the hostname of any unix machine is a security risk.

Some of your services could depend on that name. I wonder if the app team must install a new app every night becouse if they only have to do that let's say once per month you should assist them to do that. Better talk with them and try to understand why they have this requirement from you. Maybe there is one missunderstanding of the problem.

Hey;

>.# hostname mynewhostname

You should also use "uname -S ${newhostname}" although, like the others, I find this quite squirrelly. There's something not right going on there if they need to change the hostname in order to install an app...

you can use "set_parms hostname" command to change hostname .

It will change hostname on permanent basis...

Yes but you can "permanently" change it back. :-)
