# Cancel Process with Ctrl + C will not work in Terminal

I have just got myself a Ubuntu server and for some reason the Ctrl + C will not kill the process I am running. I have run this command on two terminals Cygwin and putty and logged in using ssh.

I can use the command locally and this is not a problem and also on other machines using Solaris. I have read some other posts on this site relating to this issue, however, my issue is still not resolved.

As the command works locally I am fairly confident that is not something in bash that needs to be set. (I use bash on all the machines I use). I am not trying to close processes like man or less using this command just scripts and standard processes where you expect it to work.

I have also tries Ctrl + Z and that does not work properly so not sure why it wont pick up any of these VERY useful commands. This is highly annoying for me.

I would like to learn as much as I can about Ubuntu as I have very little experience with it, if you have a solution can you include as much detail as possible?

Here is my stty -a:

speed 38400 baud; rows 24; columns 80; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = M-^?; eol2 = M-^?;
swtch = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W;
lnext = ^V; flush = ^O; min = 1; time = 0;

Welcome to Ask Ubuntu! Is there any special process in particular where this happens? –  Octavian Damiean Feb 10 '12 at 9:39
Just whenever I log into my ubuntu server. This is with which ever user I use (I have two). –  user700786 Feb 10 '12 at 9:45
You mean you can not ctrl-C any program, or just a particular one? –  psusi Feb 10 '12 at 14:46

Could you provide the output of stty -a? –  geirha Feb 12 '12 at 9:41
