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 ?

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.

A local service :>provider is going to be using ISDN in the near future, and I'd like to :>use it (a lot cheaper than 56K.) :> : :Yes, it sure is. I am all so looking into ISDN and Linux.. 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). :> What is entailed in using ISDN with Linux? I take it there's an :>ISDN card for the computer. How does Linux use the card? Does it treat it :>like an ethernet card, or something else? :> :> Bell tells me I'll need an ISDN Terminal Adapter. What is that, :>and will I have that when I have the card? They give me an NT-1, whatever :>that is. :> : :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. -- ============================================================================= *** These are my opinions...
