Some common questions: ---------------------------------------------------------------------- Q: My operating system isn't supported, but it was supported in Pidentd 2! A: Please send me patches to add the needed support for Pidentd 3! (Don't forget to make the old kernel-growling code threads safe at the same time if you take the code from Pidentd v2!) ---------------------------------------------------------------------- Q: I use Solaris 7 and I just recompiled Pidentd. But now it only responds with "kvm_open: Bad file number" whenever I try to run it one our Ultra workstations. A: Pidentd needs to be compiled with a 64 bit compiler when run on a 64 bit platform (which almost all Ultras are). Currently (981126) this requires atleast the WorkShop 5.0 compilers from Sun. Gcc can not be used. Compile with: csh/tcsh: setenv CC cc ; ./configure sh/ksh/bash/zsh: CC=cc ./configure ---------------------------------------------------------------------- Q: I use IBM AIX 4.2 and Pidentd returns user numbers instead of names, why? A: Because of a bug in the reentrant libc versions of getpwuid_r(). Either install patch APAR IX60843 (recommended), or build the non-threaded version of Pidentd (not recommended) with "./configure --without-threads". ---------------------------------------------------------------------- Q: My Unix doesn't have a threads library - where can I find one? A: One usable Pthreads library that has been ported to a number of Unixes is Proven's library. It can be FTP'd from: ftp://sipb.mit.edu/pub/pthreads/ However, I do not guarantee that it will work to build a threaded pidentd for your operating system with that threads library. ---------------------------------------------------------------------- Q: I just upgraded from Solaris 2.x to Solaris 2.y _and_ have recompiled Pidentd - but it doesn't work (fails compilation or at runtime). A: Make sure you are using GCC 2.8 (or later) or have updated your GCC compiler installation so that it has installed *new* header files. You can not use a GCC <2.8 configured for 2.x on a 2.y machine (the "fixed" header files will be incorrect). ---------------------------------------------------------------------- Q: I just upgraded from Solaris 2.5 to Solaris 2.6 _and_ have recompiled Pidentd, and have read question 3 - it still fails compilation: A: Also make sure you have applied the patch to GCC <2.8 from the Solaris FAQ: http://www.wins.uva.nl/pub/solaris/solaris2.html ---------------------------------------------------------------------- Q: I use the beta version of IRIX 6.5 and are getting incorrect results. A: There is a bug in the reentrant function getpwuid_r(). You must configure with "--without_getpw_r" and recompile (or complain to SGI so that you'll get a fixed libc). ---------------------------------------------------------------------- Q: I just compiled it on Solaris 2.4 - and it doesn't work. All I get is "NO-USER". A: Make sure you have only installed _one_ of the patches: 102049-04 (I recommend this one) 102303-05 You can't have both installed at the same time. ---------------------------------------------------------------------- Q: I'm trying to compile with Gcc on Digital Unix 4.0D or 4.0E but I'm getting errors from <c_asm.h>. A: You must use Dig^H^H^HCompaq's own C compiler when building multithreaded programs - or install patch kit #3 for 4.0D and patch kit #1 for 4.0E which will fix this bug in the pthread.h header file (it shouldn't include the c_asm.h header file for non-DEC C compilers). Or you can manually patch the Gcc "fixed" "pthread.h" header file so that the "#include <c_asm.h>" is moved down one line. ---------------------------------------------------------------------- Q: I'm trying to compile with Gcc on HP-UX 9, but the server always responds with "NO-USER" when I test it. A: Make sure that your GCC is configured for exactly the right machine type you are running it on. A Gcc built on a HP9K/800-series will not build correct kernel lookup could on a HP9K/700-series machine (and vice-versa). A workaround for HP9K/700 machines is to build Pidentd with: make "CC=gcc -D__hp9000s700" ----------------------------------------------------------------------
