if I were to ask my question again, it would be:
is there a version of 'su' or equivalent piece of software which uses rsa/dsa
keys to authenticate locally, instead of password? I don't want to have sshd
running for this because its a local login. I didn't find much on this in
google, that's why asking here.
I've never heard of such a critter, but that sure would be nice. I get
a little tired of typing my root password over and over again on my
personal box :}
sudo will allow multiple commands within a certain time period, without
re-asking for the password, which is handy.
I also have a stupid little program installed on some boxes, in /usr/bin,
owned by root, suid:
#include <stdio.h>
#define ERR stdout
main(argc, argv)
int argc;
char *argv[];
{ int myuid;
if (argc < 2) {
fprintf(ERR, "root: Usage: %s <cmd> [arg] [...]\n", argv[0]);
exit(1);
}
if (setuid(0) < 0) {
fprintf(ERR, "root: Can't become root\n");
exit(1);
}
execvp(argv[1], &argv[1]);
fprintf(ERR, "%s: Command not found\n", argv[1]);
exit(1);
}
If it doesn't exist, someone could probably write a PAM module to do
it, since 'su' under Solaris uses PAM for authentication.
