Cntl C exits shell after 11i upgrade?

Edward Massaro_1 — Wed, 27 Oct 2004 09:10:48 GMT

my DBA's are experincing an issue when they issue a cntl-c. Rather then it ending the script they are running, it is closing there session . Any clues?

What does "stty" report the interrupt setting to be? It should be "intr = ^C".

speed 9600 baud; -parity hupcl
min = 1; intr = ^C; quit ; erase = ^H; kill = ^U;
swtch ;
stop ;
brkint -inpck -istrip icrnl ixoff onlcr
-iexten echo echoe echok
-echoctl -echoke

nope

Just double-checking: you are reporting what you see when you're logged in as them, aren't you?

I've seen ^D close sessions before but I'm not sure where this gets set. It seems that whatever switch normally gets set to ^D might be getting set to ^C but I don't know where to look. Anyone else?

The last line in their .profile wouldn't happen to be "exec ..."? If so, when they kill their script, there's no parent pid to return to so they are all done.

i did find this in the .profile for the user in question.. could this be the issue?

stty erase "^H" kill "^U" intr "^C" eof "^D"
stty hupcl ixon ixoff

i think that eof may be the culprit.

Since it's ^C that causes their sessions to close, I wouldn't think that eof would be the culprit unless eof was set to ^C.

Try running stty -a and see what you get.

The other piece of this puzzle is how are they connecting? ASCII terminal? PC with emulation software? Web client? You need to ensure that the terminal settings on that side of the connection are matched with what the shell has.

For what it's worth, here's the stty -a signal settings that I have for my telnet session via Exceed emulation software:

intr = ^C; quit = ^\; erase = ^H; kill = ^U
eof = ^D; eol = ^@; eol2 = ^[; swtch
stop = ^S; start = ^Q; susp ; dsusp
werase = ^W; lnext = ^V

control-D is the traditional end of file, so that shouldn't be causing you any grief. What do they have "quit" set to?

we got it fixed guys .. there was a trap command in the .profile that was hosing everything up.

Thanks for all of the help
