I regularly ssh to a centos 5 box. Somehow they keys are mapped so that control+d will log me out of my current shell. If I am sudo'ed to another use it puts me back to the previous user. If I am not sudo'ed it just disconnects me. How can I keep this from happening? I regularly use control+d to cancel out of the python interpreter and sometimes I accidentally press it more than once.
How can I keep control+d from disconnecting my session?

You're looking for the IGNOREEOF environment variable if you use bash:IGNOREEOFControls the action of an interactive shell on receipt of an EOF character as the sole input.        If  set,  the  value  is  the number of consecutive EOF characters which must be typed as the        first characters on an input line before bash exits.  If the variable  exists  but  does  not        have  a  numeric  value, or has no value, the default value is 10.  If it does not exist, EOF        signifies the end of input to the shell.So export IGNOREEOF=42 and you'll have to press Ctrl+D fourty-two times before it actually quits your shell.POSIX set has an -o ignoreeof setting too. So consult your shell's documentation to see if your shell has this (it should), and to check its exact semantics.
