su command in *shell* buffer does not work.
su does not ask for the password and exits with "su: Sorry".
/* *shell* buffer (24.4) */
Warning: no access to tty; thus no job control in this shell...
yokohama% su
su: Sorry
yokohama%
su in *shell* buffer works well on emacs-24.3.
/* *shell* buffer (24.3) */
yokohama% su
Password:
# exit
yokohama%

I tried the following: 1. Remove my .cshrc and .login. 2. Logout and login, and launch a terminal emulator (dtterm) on X Window System in my Solaris 10 system (i386-pc-solaris2.10). 3. On the terminal emulator, I type the following: set path = (/usr/bin . /usr/ccs/bin) gzcat emacs-24.3.tar.gz | tar xfp - (cd emacs-24.3; ./configure --with-jpeg=no --with-gif=no; make) (cd emacs-24.3/src; ./emacs -Q) M-x shell % su Password: ******** # => su command in *shell* buffer works well. C-x C-c 4. Then I type the following on the same terminal emulator: gzcat emacs-24.4.tar.gz | tar xfp - (cd emacs-24.4; ./configure --with-jpeg=no --with-gif=no; make) (cd emacs-24.4/src; ./emacs -Q) M-x shell Warning: no access to tty; thus no job control in this shell... % su su: Sorry % => su command in *shell* buffer does not work. su does not ask for the password and exits with "su: Sorry".
