Is it possible to send a pre-login message using the SunOS?  It seems to
be used often by government sysadmins to warn people they are trying to
get into a government machine before they get the login prompt.  I suppose
others use it for similar reasons.  I thought it would be done just like
/etc/motd but I can't seem to find any information on how to do it.  Any
assistance on how this can be done with the SunOS would be appreciated.
THANKS!

Solaris 1.x/SunOS 4.1.x doesn't have an "/etc/issue" file; for serial
ports, you can, I think, tweak one of "lm" or "im" in "/etc/gettytab",
but I don't think that helps for TELNET or "rlogin" sessions.

I don't know which Solaris 2.x releases use "/etc/issue" (it has the
annoying habit of being controlled by an #ifdef in at least some SV
releases - an #ifdef that, at least in some of them, is *NOT* turned on
by default), nor whether those that do honor it for TELNET or "rlogin"
sessions.

/etc/issue only works or real serial ports in Solaris 2.3 and earlier.
Finally in 2.4 it works for all logins.

Get tcp_wrappers.  The 'banner' option does that.  (And gives you a lot
more control of various services.)

there's a hacked login floating around the net [in the loginlog pkg?]
which includes most of the sV functionality, including dialup passwds
and /etc/issue.

try /etc/issue. This will not work for SunOS 5.0-5.3

This is comp.unix.solaris where I am reading this.  99% of the posts here
deal with Sol 2.x, which is SYSV.  /etc/issue in 2.4 now works just fine,
with all connections, including telnet.  If you are on SunOS 4.x, you can
rename in.telnetd to in.telnetd.BIN, create a script named in.telnetd which
echos the desired message, or cats /etc/issue, or whatever you want, then
execs the real in.telnetd.

: How about simply putting the message in /etc/gettytab? It works just
: fine for me.

  How do you make a entry in /etc/gettytab to do this?

As I said in another message, this only works on real serial ports and the
console.  I just did a telnet to bigdog, which I am not sure is the machine
with this in gettytab, and I got the following:

[34](64)_nova_ellis_/faculty/ellis/public_html/directory> telnet bigdog.fred.net
Trying 204.215.84.2 ...
Connected to bigdog.fred.net.
Escape character is '^]'.

SunOS UNIX (bigdog)

login:

I just tried fred.net as well, and it is an alias for bigdog.
