I create the following shell script owned by root: Yes, as was discussed before, setuid shell scripts are security holes that you can drive trucks through. Give me a setuid shell script, and a non-privileged logon, and in 15 seconds I can become root on your system.

Since those questions have all but disappeared since Peter included the descriptions, I'll assume it has roughly worked. Unfortunately the accompanying document which explained what I meant by OPT,REC,IMP did not get included. Ah well. In any case, this answer is pretty much the right one. Unfortunately this scheme doesn't allow the relative importance between packages to be elucidated: for example, if you want openlook, then X11 is mandatory.

Ege) Subject: installing ftape-0.9.6 Date: Sat, 16 Oct 1993 15:22:38 GMT my installation of ftape-0.9.6 has run into trouble. Maybe a kind soul can help me to continue. Here is a history of what I did: - SLS base with pl13, gcc 2.4.5 - got ftape-0.9.6 from sunsite.unc.edu - instructions say to first install the "modules" (1. questions: does that mean that I have to add the modules package to every new linux patch level in order to use ftape ?) - the instructions for the "modules" package refer to pl12. The supplied diffs file works on my clean pl13 source, but a kernel make does not compile. - the reason why it does not compile is that it needs to be compiled with g++. OK, so I change the top-level makefile to g++. Kernel compiles, except for the zBoot subdirectory. OK, so I change that makefile to use gcc. All compiles, links and gets me a new boot disk image. - further following instructions in the modules package, reboot and compile and install the files in the utils directory. - notice that the makefile uses "cc" but really requires "g++" ! - now, I try to insert the sys_hello.o module into the kernel, get error message: insmod sys_hello.o Kernel symbol problem 1 - and lsmod Module: #pages: - so now I am stuck ! Is there a way to install ftape without the modules package ? Any help is appreciated. -- Raimund K.
