My main job for the last 10 years or so is porting different low level security apps to UNIX platforms. AIX is almost always the "difficult" one. Everything is always implemented differently. I code around the native security databases (/etc/passwd, shadow, /etc/security, TCB, etc) and AIX is always the strange one. I do have to say though that HP-UX has its quirks, although it generally conforms. Linux is easy, cos you can find the code to everything, so you can code round stuff or at least find out how it works. And there are always lots of people that have tried stuff or implemented stuff and its all relatively up-to-date. I have to admit though that Solaris is my favourite...things just seem to work, and if they dont a quick O/S patch usually fixes it. That is until Solaris 10 where, although I love some of the additions, I hate the horrible SMF service stuff, and process contracts that can make life a pain.

Anyhew, on the linker front, that is why I suggested libtool. You *can* make build systems that build generically and you dont need to know this low level stuff.

But thats all my 2c worth...other people have different views on libtool.

SAFE_FINGER(8)						     Linux Programmer's Manual						    SAFE_FINGER(8)

NAME

       safe_finger - finger client wrapper that protects against nasty stuff from finger servers

SYNOPSIS

       safe_finger [finger_options]

DESCRIPTION

       The  safe_finger  command  protects  against nasty stuff from finger servers. Use this program for automatic reverse finger probes from the
       tcp_wrapper (tcpd) , not the raw finger command. The safe_finger command makes sure that the finger client is not run with root privileges.
       It  also  runs  the finger client with a defined PATH environment.  safe_finger will also protect you from problems caused by the output of
       some finger servers. The problem: some programs may react to stuff in the first column. Other programs may get upset by thrash anywhere	on
       a  line.  File  systems may fill up as the finger server keeps sending data. Text editors may bomb out on extremely long lines.	The finger
       server may take forever because it is somehow wedged.  safe_finger takes care of all this badness.
