keystrokes not echoed to console

gusthecat · 01-07-2013, 09:02 AM

I have RH6.3 kickstart. After the packages are installed, the system reboots and a scripts runs that prompts for a hostname. When the hostname is typed the keystrokes are not echoed to the console although the keystokes are actually read by the script. This is not an issue with RH5.

Any ideas why the keystrokes are not echoed?

Thanks

It may depend from the script itself, even if this behavior is normally used to read passwords. A way to disable the terminal display is

Code:

stty -icanon -echo

Anyway, can you show us the script? Using [CODE] and [/CODE] tags, please.

If you have access to the GUI, can you reconfigure your keyboard from there and see if it would work.

There are actually 2 scripts. One that runs after reboot which call the scripts that sets the hostname

install-post.sh

Code:

cd /tmp/iqcustom/scripts
./set_hostname.sh

set_hostname.sh

Code:

    local hn=""

    while [ TRUE ]; do
        echo -n "Enter host name: "
        read hn
        case $hn in
            "")
                # make sure something is entered
                # will be confirmed later
                continue
                ;;
            *)
                break
                ;;
        esac
    done

Could this be related to how the boot.log file is updated? The boot.log contains all the output from script.
I ask because I have experienced a similar but not exact issue using tee while prompting for input.
