Subject: 1.800: How do I control how hostnames are resolved?
From: <kraem@ibm.de> Frank Kraemer

Information from AIX 4.1.2 Infoexplorer:

The default order can be overwritten by creating the configuration file,
/etc/netsvc.conf and specifying the desired order. Both the default and
/etc/netsvc.conf can be overwritten with the environment variable,
NSORDER. If either the /etc/netsvc.conf file or environment variable,
NSORDER are defined, then at least one value must be specified along with
the option.

examples: 
    echo hosts = local,nis,bind >/etc/netsvc.conf
    NSORDER=local,bind; export NSORDER

[Editor's notice: As of AIX 4.3 you also have bind4 & bind8 (for IPv4 & IPv6)]

Subject: 1.801: dtlogin ignores /etc/profile?
From: Trevor Bourget (trevor@thomsoft.com)

Read the /usr/dt/bin/Xsession script.  You can add a file to the
/etc/dt/config/Xsession.d and it will get sourced as part of the
startup.  The order is: $HOME/.dtprofile, /etc/dt/config/Xsession.d/*,
/usr/dt/config/Xsession.d/* (backwards, in my opinion, but CDE is a
committee result after all).

From: Ed Ravin <eravin@panix.com>

If you want your terminal session to automatically read in
/etc/profile and your .profile when they start up, you need to either
invoke them with the "-ls" option (which I couldn't figure out how to
do, perhaps someone else can elaborate), or set up the default X
resources so that they set:

*Dtterm*loginShell:     true

You could always do this with the .Xresources file in your own account,
but that wouldn't fix any other users in the system.  To make this change
globally:

CDE configuration files are kept in /usr/dt/config
 
Those files warn you strenuously not to change them, since AIX upgrades
will overwrite them and lose your changes.  They recommend that you copy
the files to /etc/dt/config and change them there, so:

# cd /usr
# find dt/config -print | cpio -pdvum /etc
... (files get copied)
# cd /etc/dt/config/C
# echo "*Dtterm*loginShell:     true" >> sys.resources
# cd ../en_US
# echo "*Dtterm*loginShell:     true" >> sys.resources

From: Olaf Meeuwissen <olaf@IMSL.shinshu-u.ac.jp>

The problem is in /usr/dt/bin/Xsession.  This script only recognizes
the following login shells: sh, ksh and csh (as of $Revision: 1.10 $).
All other shells are considered non-standard.

The fix is to have your sys-admin add any other login shells in the
right places in the script (twice in the "Start the session" part).
Look for "case ${SHELL##*/} in" and add shells in the patterns.

Note that this script will be overwritten unconditionally by system
updates :-( and, unlike much other stuff in /usr/dt/, copying it to
/etc/dt/ does not work.

For which shells to add, you may want to:

   $ grep shells /etc/security/login.cfg

Subject: 1.802:  Where's the C compiler?

As of AIX 4.1,  the C compiler has been "unbundled."  It's a separate product,
and you must purchase a separate license for it.  IBM does offer free
time limited trial licenses if you want to "try before you buy."

The GNU C compiler is available from various sources.  The most convenient
is probably <http://www-frec.bull.com/>.  <ftp://aixpdslib.seas.ucla.edu/>
is another source.
