hi there,

I need to find out a way of how to get the AD bound computer name of a computer via bash script.

Reason being that ive recently deployStudio deployed an image to a few hundred clients only to realise that the bind-name is not reflected into the LocalHostName, HostName or ComputerName values in OSX. What id like to do is deploy a script/command via ARD  that will grab the AD compName then:

scutil --set ComputerName $ADCompName
scutil --set LocalHostName $ADCompName
scutil --set HostName $ADCompName

Thanks for all assistance experts.

I'm not sure, I understand the question, so sorry, if I'm wrong.

sudo scutil --set ComputerName newName
sudo scutil --set HostName newName
sudo scutil --set LocalHostName newName
Do you ask about that?

Mac OS X 10.6 Server Admin: Changing the Server’s Computer Name and the Local Hostname

http://osxdaily.com/2010/09/06/change-your-mac-hostname-via-terminal/

The following line will show the computer name in bash:
networksetup -getcomputername

This one will show the hostname:
sysctl -n kern.hostname

Hi there --

I want to do the exsact opposite as to what you've described friend. I want to somehow grab the AD computername, that is, the computername that was used to bind to AD and THEN set the variables/values of ComputerName, LocalHostName, HostName to the value of the computer name.

Any ideas?

Thanks alot

Is samba involved?
if so look for "netbios name" in the smb.conf.

Otherwise check the configuration of the tool you connect to AD with.

I am not a scripting expert, but I came up with a script you can send with ARD to accomplish the task. It seems there is a change from 10.6 and earlier to 10.7-10.8, which is that a dollar sign is appended to the end of the Computer name record in 10.7 and 10.8. Whether that bothers you or not, the "set --LocalHostName" fails when there is a dollar sign at the end. I came up with two slightly different scripts, one which removes the last character of the name, and one which does not. I am sure there is a way to merge this into one script which removes the dollar sign if it is present, but these two scripts work:

For 10.5 and 10.6:
#!/bin/sh
ADCompNametemp=`dsconfigad -show | grep "Computer Account" | sed 's/Computer Account//' | sed 's/=//'`
ADCompName=${ADCompNametemp//[[:space:]]/}
scutil --set HostName "$ADCompName"
scutil --set LocalHostName "$ADCompName"
scutil --set ComputerName "$ADCompName"

Open in new window


For 10.7-10.8
#!/bin/sh
ADCompNametemp=`dsconfigad -show | grep "Computer Account" | sed 's/Computer Account//' | sed 's/=//'`
ADCompNametemp2=${ADCompNametemp//[[:space:]]/}
ADCompName=${ADCompNametemp2%?}
scutil --set HostName "$ADCompName"
scutil --set LocalHostName "$ADCompName"
scutil --set ComputerName "$ADCompName"

Open in new window
