I didn't have 'religious wars' in mind when starting this thread. I only
|
||
wanted to know if there will be an update that uses XFree86 3.1 libs.
|
||
It's a technical problem for me - I want to use X11R6 features within the
|
||
Motif environment. As X11R5 apps still work (and I've got an awful lot of
|
||
them since I update my system no more than once a year) and as I don't want
|
||
to recompile them all, I don't see the point in maintaining X11R5 sharedlibs.
|
||
It's a pity that I have to wait even longer ... in the meantime, I'll
|
||
do X11R6 testing with Athena widgets.
|
||
|
||
For what I've tested myself, I can compile Motif apps with X11R6 includes;
|
||
but when linking, I have to use the 'old' R5 libs. And I don't see any
|
||
reason why Motif apps (or any old X11R5 apps) shouldn't compile with R6
|
||
includes - R4 apps compile with R5 includes very well, and added entrys
|
||
withing the include file usually don't make troubles - just changed entrys.
|
||
|
||
But there's one major problem that should be fixed (somehow). With Metrolink
|
||
Motif, there came the mxmkmf script that correctly called imake with Motif
|
||
templates. This no longer works for me. I don't know enough about configuring
|
||
imake, I'm just using it, so please could someone point me out what to do ?
|
||
|
||
Hey guys: don't just flame Metrolink - I'm more angry about the Slackware
|
||
distribution originator. Why the hell does he have to create such a chaos
|
||
like /usr/X11, /var/X11 -> ../../X11, /usr/X386 -> X11, and so on ?
|
||
This difference /usr <-> /var and the gigantic amount of softlinks between
|
||
these dirs cost me half a day to clean up; I just don't want to install
|
||
X11R6 (Xfree86 3.1) in /usr/X11 when I still need Xfree86 2.x; but when I
|
||
wanted to make sure X11R6 stuff is used preferably, I had to recurse all these
|
||
subtrees to delete unecessary things - I now think it would have been easier
|
||
to remove all X11R5 stuff, then setup X11R6 and after that, untarring the
|
||
needed files from X11R5 to /tmp and selecting the necessary things - But
|
||
how should I know before ?
|

One more thing:

Is there already a release date for Motif 2.0 ?

Subject: Absurd backup problem with tar
|
||
Date: 12 Oct 1994 13:09:40 GMT
|
||
|
||
Well, we have a net setup here, and I want to make a backup using tar.
|
||
tar clvf woody:/dev/rmt1 /usr
|
||
will do the trick. Mostly. It will refuse to work if I'm super user,
|
||
but of course, if I'm not, I cannot necessarily read all the files.
|
||
|
||
The problem lies with /usr/bin/rsh, which will require a password when
|
||
logging in as super user (interactively) or just fail (non-interactively,
|
||
as in
|
||
rsh woody pwd
|
||
|
||
Now is there a possibility of getting this to work? At the moment, I have
|
||
made a file /usr/ucb/rsh (first place tar looks) which is just root
|
||
executable and has
|
||
exec su nobody -c "exec /usr/bin/rsh $*"
|
||
in it. Somewhat of a weak solution. Anybody know any better one?

Ugly. Either something's broken or your kernel is really too big (are we

device drivers and other kernel features would shrink it to a more
|

|

|

This tells you that LILO thinks your kernel would be too big to load.
|
||
Either LILO is wrong or what it thinks is the kernel isn't or the
|
||
(compressed) kernel is really bigger than half a megabyte. (Re-building
|
||
the kernel and examining the paths listed in /etc/lilo.conf should help
|

eliminating the first two (unlikely) possibilities.)

Has anybody seen this problem too ? Is it time to finally start the

|

|

No, that's not a failing copy operation. LILO typically only allocates
|
||
a few kB of disk space.

When laying out your Linux partitions, consider your 'distribution'

guidelines.... For example, Yggdrasil suggests a dedicated

root partition WITHOUT installation modified files as their
|

upgrade to next release assumes they can reinstall the whole

root partition but preserve the others. If you are installing

|

|

Definately cheaper than 56Kbps, but still quite expensive all things
|
||
considered. First, you need to install an ISDN line. The installation
|
||
charges run anywhere from "normal line installation" to special install
|
||
charges. Southwestern Bell charges ~$585 (they have a special going right
|
||
now for ~$94 install, but it will go back up on Oct. 24). Second, you'll
|
||
need (in the US) an NT1. This device is supplied by the telephone company in
|
||
_other_ countries (outside the US), but in the US it is customer supplied
|
||
equipment. Prices range from ~$200 to $700. (See below for a suggestion...)
|
||
Next, you will need to purchase an ISDN "terminal adaptor" (T/A). The T/A
|
||
can be anything from an ISDN ready phone, to an ISDN bridge, to an adaptor
|
||
card for your PC. It simply connects a device to the ISDN line. Some T/A's
|
||
even include the NT1 (of course, they cost extra for the luxury...). T/As
|
||
range from ~$600 on up to several thousand. After you have all the
|
||
equipment, you will need to purchase a connection to an Internet provider.
|
||
In _most_ cases, they will provide you with a "dedicated" dialup (kind of
|
||
defeats the purposed of "dialup") dialup line (i.e., your _own_ phone number
|
||
to call for the service). Many of these will only allow you to connect on a
|
||
single "B" channel as well. Given that you will (basically) be the only one
|
||
using your dialup line -- you should expect to pay the full cost of the
|
||
provider's ISDN service (for that line), plus their markup. Some of them

cost as little as ~$100 (for a single-site line -- where you only get 1 IP
|

address assigned to you) to ~$400 for a full Internet feed (say from "PSI",
|
||
for example).

:> Bell tells me I'll need an ISDN Terminal Adapter. What is that,

|

:>
|
||
:
|
||
:Yes, You will get a NT1 card and power supply. The bell's do not supply
|
||
:line power in the USA for ISDN. I think, in other counties they do.
|
||
:
|
||
:If you are running BRI (Bacis Rate Interface) That is what most home users
|
||
:have. You will Need a NT1 card for your computer that will connect to the
|
||
:U interface that you RBOC will install. plus the power for the NT1..
|
||
|
||
The NT1 converts the 2-wire "U" interface provided by the RBOC (Regoinal Bell
|
||
Operating Company), to a 4-wire S/T interface used by the T/A. The T/A is
|
||
simply the equipment on your side that connects to the ISDN line (as stated
|
||
before: it can be a phone, bridge, adaptor card, etc.)
|
||
|
||
As for needing a "card" to do ISDN over Linux -- a simpler solution would be
|
||
to use an _already_ supported Ethernet card and buying an ISDN-Ethernet
|
||
bridge to the remote network. Then the Linux box _never_ has to know that it
|
||
is talking over ISDN. As far as Linux is concerned, it _only_ has to talk
|
||
"Ethernet"... Of course, it would probably depend a great deal on what your
|
||
Internet provider can offer...
|
||
|
||
:> I get two "B" channels. Does one ISDN card only use one "B"
|
||
:>channel? Can I use another ISDN card to have two 64K links to my service
|
||
:>provider (assuming I pay them twice)?
|
||
:>
|
||
:
|
||
:No, The NT1 will use both B Channels as well as the D channel.
|
||
:With this you can have one link to your provider and be talking on your
|
||
:ISDN Digital phone each on one B (64KPS) channel while downing a file
|
||
:from your local BBS on the D 16 kps or (9600 or 14.4 modem speed) channel.
|
||
|
||
The NT1 doesn't really _do_ anything useful (as far as the user is
|
||
concerned). It is _purely_ to convert the wiring to an appropriate spec for
|
||
use with the T/A.
|
||
|
||
As stated before, the Internet provider (or remote site) you use will dictate
|
||
how many "B" channels you can use. For example, we have some Combinet
|
||
Ethernet to ISDN bridges here, we connect to a remote site. We have the
|
||
bridges configured to "dynamically" dial the remote system on the first "B"
|
||
channel when "more than 0 (zero) bytes are received". Then, when we are
|
||
receiving more than 48Kbps for 10 seconds, we have it automatically start up
|
||
the second channel (it automatically does load balancing and multiplexing).
|
||
This configuration was intrinsic to the Combinet bridges (but most of the
|
||
ISDN-Ethernet bridges we've seen do the same stuff).
|
||
|
||
As for using the 'D' channel for "modem-like" speeds... The "D" (Delta)
|
||
channel is used to control the connection (initiate, tear-down, setup, etc.).
|
||
In other words, when you attempt to call from one ISDN T/A to some other
|
||
phone number, the phone number you are trying to reach is sent in a packet
|
||
through the "D" channel. The remote side (if it is ISDN) recieves the
|
||
incomming connection request on its "D" channel. Then both sides agree to
|
||
open a "B" channel for voice or data. It is possible to have the phone
|
||
company setup X.25 (Packet switched data) connections through the "D"
|
||
channel, but it requires an X.25 PAD and some other specialized equipment.
|
||
In the U.S., it would probably cost significantly more to get this
|
||
configuration "workable"... So I doubt it would be worth it (also, you'd
|
||
have to get someone else to setup for receiving X.25 packet-switched data.
|
||
|
||
:> Is there any other information about ISDN that I'll need. Anyone
|
||
:>putting together a FAQ for this?
|
||
:>
|
||
:
|
||
:Look over on comp.telcom.isdn or something like that.
|
||
:I have a WWW address but, can not remember it right now.
|
||
:I think you can gopher bellcore as well.
|
||
|
||
The _best_ ISDN site I've found (in the U.S.) is "Dan Kegel's ISDN Home Page"
|
||
(found at: http://alumni.caltech.edu/~dank/isdn/). It is a fairly
|
||
comprehensive list of ISDN equipment, FAQs, and other WWW home pages.
|
||
|
||
Now, a little tidbit of _useful_ information: IBM is selling a device called
|
||
the: "IBM 7845 Network Terminator Extended" (found on Dan Kegel's home
|
||
page...). This device is an NT1, plus a couple of _neat_ features. First,
|
||
it is an NT1, and it only costs $350 (about $120 more than the cheapest NT1
|
||
I've found so far). So it provides the same features as the standard NT1.
|
||
Next, it provides ISDN-Analog (POTS) line conversion. This means that you
|
||
can hook-up your standard house-wiring to the device and use your standard
|
||
analog telephones (the one's you've always used). Third, it provides some
|
||
"special" telco tricks: Speed dialing, last number re-dial, call hold, return
|
||
last incoming call, call waiting, call retrieve, three-to-six way
|
||
conferencing, etc. Finally, it has a battery back-up system, that provides
|
||
18hours of "standby" (i.e., wait for a call), or 6-hours "off-hook" use.
|
||
|
||
So, you can hook your ISDN T/A to one output wiring system, and hookup your
|
||
house telephone system to the other. You get _both_ ISDN and POTS service.
|
||
This is _not_ a commercial, I am just excited about the possibility of such a
|
||
device.

Symbolic links are what makes Linux (and every other Unix) behave sanely with a
|
||
variety of programs which expect different paths. For example, /usr/bin is
|
||
linked to /usr/bsd because on some machines certain programs are located only
|
||
in /usr/bsd. I've seen /var/adm as /usr/adm. There are many more examples of
|
||
this. Theoretically, the Linux File System Standard dictates the directory
|
||
structure, but until we stop having to use software not written specifically
|
||
for the Linux directory hierarchy, the symbolic links will have to stay.

Subject: linux bootable on second SCSI-HD
|
||
Date: 14 Oct 1994 14:41:36 GMT
|
||
|
||
|
||
Hello ot there,
|
||
|
||
I'm happily running Linux on my first SCSI-Disk (on sda3, to be true,
|
||
with DOS on the first two partitions for those users in our lab that
|
||
that can never really QUIT wordperfect and the like). Now, as large
|
||
amounts of data are to be expected from a new experimental series,
|
||
I will have to move my Linux to a second SCSI HD (using AHA1542).
|
||
What I need to know is simply:
|
||
|
||
How do I make a bootable floppy (the "dd if=zImage of=/dev/fd0 ... style)
|
||
which accesses the second drive as / ? Can I use "rdev.... or something ?
|
||
I know that I need to reconfigure my *tabs in /etc to mount the whole
|
||
fss', but how do I get Linux to start ?
|
||
|
||
Thanks in advance for your helpful comments !!!
