control-c key during rc script running

hot948 — Fri, 06 Jan 2012 07:47:23 GMT

Using hp-ux 11.31.

Where do I control control-c(abort) in the middle of runing rc script on booting?

while rc scripts(/sbin/rc*.d) is running, rc script aborted when I tried to control-c key but

On other system this control-c key do not effect. How to control control-c during booting?

From MP console:

HP-UX Start-up in progress
__________________________

     Configure system crash dumps ................................. OK
     Removing old vxvm files ...................................... OK
     VxVM INFO V-5-2-3360 VxVM device node check .................. OK

     VxVM INFO V-5-2-3366 VxVM reconfiguration recovery ........... OK

.

I tried to control-c key and rc scripts stoped and displayed "console login" like below

(The point press control-c key is not fixed and is random)

The system is ready.

GenericSysName [HP Release B.11.31] (see /etc/issue)
Console Login:

But I can't see this symptom on other system. I don't know what difference of both of two system.

Where this signal is controled?

Presumably because on your systems the consoles have different stty settings? Compare the output of:

stty -a </dev/console

On the systems where this works/doesn't work - you are specifically looking for what "intr" is set to...

Hmm. I thought you could only do control-\ for the SIGQUIT signal.

Any reason you even tried control-C?

Hi,

Here is my test procedure:

1. login in my system from my pc trough telnet

krca# telnet mp-console-ip for the system that CNTL-C didn't work

and here do the shutdown & reboot

and return back to original system(krca)

2. and to try other system

krca#telnet mp-console-ip for the system that CNTL-C works

so I think stty is not issue of krca system.

krca#stty -a

speed 9600 baud; line = 0;
rows = 35; columns = 116
min = 4; time = 0;
intr = ^C; quit = ^\; erase = DEL; kill = ^U

Regards

So that stty output is for the client system session (krca), not for the 2 systems which you aree trying to compare... so as I said previously, on the 2 systems where you see differences you need to see the stty settings for the console (not for your client session), which you can get using:

stty -a < /dev/console
