Apply it and install TCP wrappers. 4. edit the /etc/inet/inetd.conf again and enable the wrappers for telnet (ftp discretionary). 5. if you want to use ftp, edit /etc/ftpusers. /etc/ftpusers contains a list of users which are NOT allowed to make an FTP connection. I strongly recommend not using ftp at all, however. 6. install and configure ssh - Secure Shell suite. In addition to installing on a default port, install it on a random, secret high port to serve as a backdoor in case something goes awry. Make sure it's not a privileged port. 7. obtain and install CheckPoint Firewall-1, V4.1 recommended. Configure the firewall rules carefully. If configured properly, it can be set to do IP masquerading and network address translation. 8. Obtaining and installing the RSA's SecurID is not necessary, but I recommend it highly. It's a very efficient method of authentication (you don't have a physical token, you don't get into the system). CheckPoint's FW-1 makes provisions for it an can be configured to use it. This all costs money, but if you have enough for an Ultra-1, then you can scrap enough for CheckPoint and SecurID. Or even better, get pirated copy of those, if you can. If I forgot anything, feel free to add it up to the list. ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com - ------------------------------ Date: Mon, 6 Mar 00 21:40:33 PST From: perryh@pluto.rain.com (Perry Hutchison) Subject: Need help using SPARC w/out monitor To: scott@MIT.EDU > From: Scott Ehrlich > > I now have a SparcStation 5 and a Sparc Classic, Sun 5c keyboard, and > Sun mechanical mouse.

Simple - unplug the Sun keyboards and the machines will both default to using serial port A for the console device. Make sure you are using the right cable (a null modem cable with do, otherwise wire up a cable with each pair of wires 'crossed' to make the handshaking work (ie. pins 2/3, 4/5, 8/20 crossed, pin 7 wired straight through).

I have tried connecting the serial cable for my PC and plugging into each Sparc's respective serial ports, use a terminal program, power on the Sparc, and see nothing. You should just need a null modem (and of course the 9- to 25-pin adaptation). Despite the opposite genders, Sun and PC serial ports are both "DTE". My PC serial works just fine to my Sparcstation's ttya port, using either "tip" under unix or "hyperterm" under Windows. It may help to make sure that neither a keyboard nor a monitor is connected to the Sun when you power it up.

You're right in that you only need the CPU board to make a fully-operational system in somethiing like a 4/110 case, or even one of the older 3-slot Sun VME tower cases (which is what I've done with my 4/6x0 CPU board). The VME bus is pretty much redundant if you use Sbus cards and external storage devices on the SCSI bus. Since all that's needed is the power supply connector, you can connect an external SCSI drive, load Solaris and off you go. The caveat is that since Solaris 2.6, the 4/6x0's have not been supported, but you can hack the kernel to defeat the 4/6x0 detection loop (I've got a web page about this at "http://lios.apana.org.au/cdewick/data/sunos_6x0.html". There is also no VME support in 2.6 and up, but you don't need it if you're running a single-board system. I also believe that there's no support for the Supersparc-2 (SM-71 and SM-81) CPU modules in the bootROM's, so if you have 2.14v3 (the last version of the ROM's) for your machines, you can use high-speed Hypersparc CPU modules, but nothing higher than the 60 MHz SM-61's in the Supersparc line. A pair of dual-125 MHz Hypersparc modules and 256 meg of RAM would make very formidable machines even by today's standards if they're used for raw data processing, and given the ability to use off-the-shelf RAM and SCSI drives, there's lots of life left in them.

The best way to get the right pin connections is to get a ribbon-cable version of that big D50 connector, and crimp it on to the cable you're going to use. AFAIK the only other wierdness is that some sun3's grounded the pin that should have supplied +5V to an external terminator. They need to use internal or self-powered termination on the last device, and no device should be set to supply termination power to the bus. - ------------------------------ Date: Mon, 13 Mar 2000 12:09:33 -0600 From: BHamill@mbcm.org Subject: Solaris equiv of SETVER? To: Suns-at-Home@net-kitchen.com Sorry if this is a repetitive newbie sort of question, but I can't find an answer anywhere. I have a Sparc 5 running Solaris 7 (thanks to all who suggested CD mounting hardware sources to me about a month ago). I'd like to do some computer-based training on it, but the program I'm trying to run apparently pre-dates Solaris 7- it tells me it only runs on 2.4 through 2.6. I have access to 2.6 and could install it, but I'd like to avoid that. Is there a way to fool the program into thinking it's running 2.6 when it's actually running 7? I'm thinking of something along the lines of MS-DOS's SETVER, with which you can tell DOS to report different version levels to different executables.

Nothing would make me happier than to see the 690's go to a new home intact. Unfortunately, it is not that simple. Being that we are a large company, any surplus equipment has to pass through our 'investment recovery' program, which basically means that it has to sit in storage until it loses all value, at which point the company tries to sell at a sizable percentage of its original cost. Thus, investment recovery is kind of like a purgatory for old equipment - the stuff really get caught in the system. Because of this, I think the best option would be for me to remove the VME cards and SCSI devices - may as well save the most valuable (and smallest) components. In the unlikely event that the racks (which are in really nice shape) do make it through investment recovery and come up for open sale, I will be sure to notify all those who were interested. At that point, I would certainly pass the VME cards on to anyone who purchases a rack. For all those who were wondering, I am located in Winnipeg, MB, Canada. Thanks for all of the responses...

I think this is a classical example of lost knowledge... 1) SunOS 4 does have UVM, period! In fact, Sun invented it!!! 2) SunOS 4 does use the Berkeley Fast Filesystem, period! The UFS in 4.1.1 is still based on 4.3BSD, but with 4.1.3 they started to use the newer 4.3reno FFS. This is exactly what Sun uses in todays Solaris!!! If you want to have the 4.1.3 UFS on your Sun3, go to the Sun3/3x-archive and download the "special" patch. 2 GB file system size and a clean flag, what do you need else?!? 3) SunOS 4 does come with mature device drivers for all Sun hardware, period. There are a few drivers in NetBSD that work fine, but several others (especially VME) are pre alpha or do not exist at all. 4) Sun invented/implemented a lot of new technologies in SunOS that are today considered "state of the art". In fact, Sun was the tech leader and other vendors and the free Unix-like-OS developers reimplemented this in their OSes later (some much later). SunOS is out of Development for 10 years, out of Support for 5 years now. And the gap is widening. But SunOS 4 was years ahead of other OSes and so it can be (and for me it is!) still very useful. NetBSD is fine for the mainstream workstatiosn like the 3/60 or 3/80. All devices are (more or less) supported and the drivers become more and more stable. IMHO you can now (with 1.4) live with the little problems that remain. The VME machines are a totally different story. Since i have a lot of these, i'll continue to run SunOS. If you need anything for the Sun3, software, patches, whatever, feel free to contact me. I cannot offer proffesstional support, but advice and help. I've even thrown together a Y2K-Patch for SunOS 4.1.1 so i can run these oldtimer in this century.

(a) Make sure you're using serial port A on the Suns. (b) Make sure you don't have TXD and RXD (2 and 3 on a DB-25, also 2 and 3 on typical peecee DB-9s) crossed. Try swapping them, maybe. (c) Make sure the keyboard is not plugged into the Sun. (This makes the ROMs use serial port A as console even if it's set to screen-and-keyboard, except on a few very old ROM versions. I doubt your machines are old enough to be a problem in this respect.) (d) Don't be impatient; it can take a comparatively long time before the ROMs generate any output, long enough to worry someone not used to it. Don't give up in less than a couple of minutes, I'd say. ---------------- >> what is the key sequence on a dumb term to send a stop-a? Strictly, one can't. What the serial-console abort sequence is depends on the OS (as does the keyboard-console abort sequence, actually); all OSes I know of for Suns accept a BREAK. Some accept any framing error. (A break condition is a framing error, but not all framing errors are break conditions.) If there's no OS running yet, consider the ROMs as `the OS' for these purposes. How you do this depends on the terminal. I've seen people say BREAK and Control-BREAK; I think I've also used at least one terminal that required Shift-BREAK. > It depends on the dumb terminal; the stop-A sequence is not an ASCII > character but a `break' signal, Actually, STOP-A is not a break signal. They're equivalent in only one respect, that being that just as the keyboard driver causes the OS to do something special on STOP-A, the serial console driver causes the OS to do something special on BREAK. (What "something special" is depends on the OS. Some drop to the ROMs. Some drop to a kernel debugger. Presumably other behaviors are possible.) ---------------- >> [more of the same] > The break key. This key breaks out of RS232 and zeros the output > signal for a short period.

Disconnecting the cable will sometimes generate a framing error, which will often have similar effects - but they are not otherwise equivalent. In particular, a disconnected cable does not drive the pin, whereas a break condition drives the pin to the spacing state for at least ten bit times. ---------------- > When I try to connect an external SCSI drive to my machine, the SCSI > turns off!

Acquaintances told me that there was > a problem with the way the SCSI pins are wired with some of the Sun > 3/60s. The problem is almost certainly the TRMPWR one. One of the SCSI bus pins is supposed to provide termination power. The problem is, some Sun-3 motherboards ground this pin, instead of supplying power to it. (Fuzzy memory says some other motherboards leave it unconnected.) Most likely, your external drive is jumpered to provide power to the TRMPWR pin as well, and when you connect it up, the external power supply sees a very high load because it's trying to power a pin that's connected to ground through the CPU. It promptly goes into its overcurrent foldback mode, which amounts to turning off. If you're lucky it does this before frying the part of the drive that connects power to the SCSI bus pin. The simplest fix is to jumper the external drive so that it doesn't try to provide termination power to the bus. (Getting the bus terminated may be a little difficult; you may have to have a device provide termination, and it will probably have to provide its own terminator power.) You may also be able to fix it by breaking off the relevant pin on the SCSI connector that connects to the CPU, or (if the SCSI connector is one for which this is possible) cutting the wire for that pin between the connector and the CPU board. At least some versions of jwbirdsa's Sun hardware FAQ include the pinouts you'd need. I believe there's a version up on the Web somewhere on www.sunhelp.org.... ---------------- >> IIRC, RS232 runs at 12v and the keyboard port uses RS232... is it (I think RS-232 specifies that one signal level is between +3 and +15, and the other is between -3 and -15, with the range between -3 and +3 being undefined. Certainly ±12 is a common pair of voltages.) > The Sun KB and mouse are not rs232, the are RS422, a multidrop serial > rig (though the voltage levels are the same). ...huh? That sure doesn't match my experience. The Sun keyboards I've dealt with have been just like RS-232 *except* for the voltage levels, which have been TTL voltage levels. Indeed, I have connected a keyboard to an ordinary serial port by putting appropriate level-shifting electronics in between the two.

Really, this sounds like a nice desktop system to me. (Kinda slow, compared to those oh-so-cheap Intel systems, but at least it has 24-bit graphics.) Given that, my philosphy is that one dedicates some cheap machine (a low-end pentium, or maybe even a Sparc IPX or suchlike) to the firewall role, and keeps the desktop system behind it. That way reboots and resource-hungry applications don't affect the rest of the household. And for the firewall, I doubt I'd run Solaris. There's just too much stuff to turn off. NetBSD has worked really well for me, though ipf and ipnat configuration can take some time to work out, because the configuration of such is just as cryptic as all the other systems out there. But it has the advantage of running on virtually everything. And the PPP is pretty easy to set up, though I know that Solaris has gotten a lot better since 2.5 (which required an absolute expert to set up PPP). > I also want to be able to set up ip masquerading(spelling :) Yes, that's spelt `NAT' (Network Address Translation) everywhere outside of the Linux world. :-) > From: Scott Ehrlich > I now have a SparcStation 5 and a Sparc Classic, Sun 5c keyboard, and > Sun mechanical mouse.

Are you using a cross-wire (also known as `null-modem') adapter or cable? You need to have one of these on serial port A for this to work. Make sure you unplug the keyboard, and you should see output within sixty seconds or so of booting. Make sure your terminal program is set to 9600 bps, too. (I've found that parity settings of both 8/N/1 and 7/E/1 work, though you may want to experiment by flipping back and forth between the two if you still have problems. I always use 8/N/1 myself.) In my experience, without a keyboard, a sparc will *always* spew out serial port A, so if you're not seeing anything, it's almost certainly a cabling problem or a problem with the configuration of the PC serial port. Good luck with this; I run a lot of sparcs headless, and this is one of the best things about them. cjs -- Curt Sampson 917 532 4208 http://www.netbsd.org «Quand on veut un mouton, c'est la preuve qu'on existe.» - ------------------------------ End of Suns-at-Home Digest ******************************
