->Chapter 22. Portability</H1

->Samba works on a wide range of platforms but the interface all the
-platforms provide is not always compatible. This chapter contains
-platform-specific information about compiling and using samba.</P

->22.1. HPUX</H1
-><P
->HP's implementation of supplementary groups is, er, non-standard (for
-hysterical reasons). There are two group files, /etc/group and
-/etc/logingroup; the system maps UIDs to numbers using the former, but
-initgroups() reads the latter. Most system admins who know the ropes
-symlink /etc/group to /etc/logingroup (hard link doesn't work for reasons
-too stupid to go into here). initgroups() will complain if one of the
-groups you're in in /etc/logingroup has what it considers to be an invalid
-ID, which means outside the range [0..UID_MAX], where UID_MAX is (I think)
-60000 currently on HP-UX. This precludes -2 and 65534, the usual 'nobody'
-GIDs.</P
-><P
->If you encounter this problem, make sure that the programs that are failing
-to initgroups() be run as users not in any groups with GIDs outside the
-allowed range.</P
-><P
->This is documented in the HP manual pages under setgroups(2) and passwd(4).</P

->22.2. SCO Unix</H1
-><P
->
-If you run an old version of SCO Unix then you may need to get important
-TCP/IP patches for Samba to work correctly. Without the patch, you may
-encounter corrupt data transfers using samba.</P
-><P
->The patch you need is UOD385 Connection Drivers SLS. It is available from
-SCO (ftp.sco.com, directory SLS, files uod385a.Z and uod385a.ltr.Z).</P

->22.3. DNIX</H1
-><P
->DNIX has a problem with seteuid() and setegid(). These routines are
-needed for Samba to work correctly, but they were left out of the DNIX
-C library for some reason.</P
-><P
->For this reason Samba by default defines the macro NO_EID in the DNIX
-section of includes.h. This works around the problem in a limited way,
-but it is far from ideal, some things still won't work right.</P
-><P
->
-To fix the problem properly you need to assemble the following two
-functions and then either add them to your C library or link them into
-Samba.</P
-><P
->
-put this in the file <TT
-CLASS="FILENAME"
->setegid.s</TT
->:</P
-><P
-><PRE
-CLASS="PROGRAMLISTING"
-> .globl _setegid
-_setegid:
- moveq #47,d0
- movl #100,a0
- moveq #1,d1
- movl 4(sp),a1
- trap #9

-<TT
-CLASS="FILENAME"

-></P
-><P
->then you need to add these to the LIBSM line in the DNIX section of
-the Samba Makefile. Your LIBSM line will then look something like this:</P
-><P
-><PRE
-CLASS="PROGRAMLISTING"
->LIBSM = setegid.o seteuid.o -ln</PRE

->
-You should then remove the line:</P

->22.4. RedHat Linux Rembrandt-II</H1
-><P
->By default RedHat Rembrandt-II during installation adds an
-entry to /etc/hosts as follows:
-<PRE
-CLASS="PROGRAMLISTING"
-> 127.0.0.1 loopback "hostname"."domainname"</PRE
-></P
-><P
->This causes Samba to loop back onto the loopback interface.
-The result is that Samba fails to communicate correctly with
-the world and therefor may fail to correctly negotiate who
-is the master browse list holder and who is the master browser.</P
-><P
->Corrective Action: Delete the entry after the word loopback
- in the line starting 127.0.0.1</P
