From: crompton@NADC.NADC.NAVY.MIL (D. Crompton) Date: Sat, 22 Jun 91 23:15:26 EDT Subject: GATEWAY/NETROM MBOX Problem For the first time in awhile while I was at Field Day this afternoon I logged into our TCP/IP switch with a standard TNC (no NOS) After getting the openning banner I attempted a gateway connect and did not get a connect - just a message telling it was attempting. I then entered the escape character (^X default) and it immediately told me it was connected followed be a disconnect. I experienced the same results with the netrom connect. Only here I did not see a connect confirmation but I did an 'r' command. Nothing returned. When I did the escape I got the routes back from the node and then a disconnect. What appears to be happenning is that the circuit from the connection to (me) the connecting ax25 station is not working. At least not until the escape character is sent and then of course the circuit is broken. This is with PA0GRI 0604 code. It is a recompile of the original. All other aspects of the code appear to be functioning fine. Is anyone else experiencing this?? It is simple to test. It does it thru nos as well. 'c ax0 noscall'. I recall some talk of gateway problems recently but looking back it seems that it may be unrelated.

The final config will compile the src0618.zip with no out of memory problems. The current executable is on thumper.bellcore.com in ~ftp/pub/ka9q/incoming/pop0618.exe. Here is the best config.sys to date: files = 30 buffers = 20 stacks 0,0 SHELL=C:\DOS\COMMAND.COM C:\DOS\ /p /e:800 DEVICE=C:\DOS\HIMEM.SYS /shadowram:on dos=umb device=c:\dos\emm386.exe frame=e000 h=100 ram 1024 devicehigh=c:\dos\ramdrive.sys 1024 512 1024 /e devicehigh=c:\dos\smartdrv.sys 1024 devicehigh=c:\lmouse\mouse.sys devicehigh=c:\drivers\burndev.sys devicehigh=c:\dos\ansi.sys devicehigh=c:\net\netdev.sys DEVICEhigh=C:\DOS\SETVER.EXE Placement of the frame=e000 was dictated by an ARCNET card using a window at 0xd000. I'm using the extended partition capability of DOS 5.0 rather than just one big partition so that Xenix's DOS utilities can handle the DOS partition. Getting rid of the dmdrvr.bin that handled the d: drive permitted use of the smartdrv.sys cache with Borland C++. That cuts the disk access substantially. -- Mark C.

Karn) Date: Fri, 21 Jun 91 19:49:25 EDT Subject: KA9Q QSYing to W6-land I have recently decided to accept a position with Qualcomm, Inc, in San Diego, California. My current target start date is August 1, 1991. I will be working on their CDMA (Code Division Multiple Access, aka "spread spectrum") cellular radio project. I am very much looking forward to working with the guys at Qualcomm, many of whom are hams (N6NKF, WT6G, KB5MU, WB6HHV, KA6IQA, just to name a few). As I will be rather busy over the next month with all the many details of moving cross country, expect me to be even less communicative on this form than I've been lately. However, I do plan on maintaining some continuity in NOS and related efforts. Sometime before I leave Bellcore, I will move the /pub/ka9q hierarchy from thumper.bellcore.com to ucsd.edu. This will become the new canonical collection/distribution point for NOS and related code. (Qualcomm is on the Internet, but their link is only 56kb/s and I don't want all that anonymous FTPing to bog down their link!) I will announce on this list when I've made the switch. I'll replace the old directory on thumper with a message redirecting people to ucsd.edu. I already have an account on ucsd.edu that I will probably use as a personal mail drop between the time I leave Bellcore and the time I become established at Qualcomm. Mail forwarding from Bellcore will probably be in place for a while, but of course using my new address will be more efficient. I'll let everybody know when this happens, too.

Crompton) I suspect this DEPCA board is rather old. - 1988 or earlier I believe that the Clarkson packet driver will not work on it. I'd love to have you fix it... ---- From: karn@thumper.bellcore.com (Phil R.

I expected to, but this is the second shipment from them that didn't get taxed... Geert, We do exactly what you suggested on the "value" Only problem with declaring it as NO Value is that they would not let me insure it ..!!! doug -- Doug Drye KD4NC ---- From: jrc@brainiac.mn.org (Jeffrey Comstock) Date: Sat, 22 Jun 1991 15:16:47 -0500 Subject: Re: KA9Q QSYing to W6-land In article <9106212349.AA21850@epic.bellcore.com> you write: >I have recently decided to accept a position with Qualcomm, Inc, in >San Diego, California. My current target start date is August 1, 1991. .. .. I used to live in San Diego. It is a beautiful place, and alot warmer than Minnesota. Your going to love it. When I lived there I went to Minnesota for Christmas for a few weeks and it was about 10 deg above. I got back to Cal about Jan 2 and it was 85 degrees. One thing I really loved was that even if it was 100 degree's, you go in the shade and it is very comfortable. If it gets 100 here in Mn, it is very humid, so you are like in a stew pot, boiling no matter where you go. I like to hang around the meat department at Super Valu on days like that :-). Anyway, no one probably told you this, but you have to get some of those surfer pants before you go out there. They are the ones that go down to about 1/4 of an inch above the knee, and are usually fluorescent green, yellow, pink, purple, and black (all at the same time). Make sure you preface most comments with 'Hey duuuude' also. :-) :-) Have a safe and happy QSY Phil. Also, thanks for TCP/IP. Now I am having fun with it just to network computers locally, even if the RF is turned off. Jeff ---- From: Anders.Klemets@cs.cmu.edu Date: Mon, 24 Jun 91 05:42:40 -0400 (EDT) Subject: AX.25 on top of IP I have implemented Brians RFC-1226 for transmitting AX.25 frames over IP in NOS. Apparently nobody else has done it for NOS yet? The code is pretty simple since parts of it was already there. For instance, the code for calculating the HDLC checksum was already in the file ppp.c. (Although I am not perfectly sure that I am generating the right FCS.) To make the AX.25/IP code more useful I also added a tiny piece of code that implements crossband digipeating. Here is how to use it. Suppose that I am running NOS with the callsign SK0WE-2 on the radio interface. I want to setup a wormhole with w1xxx.foo.com. I will then have to type: attach axip ai0 256 w1xxx.foo.com sk0we-3 where "ai0" is the name of my new 'wormhole' interface. "256" is the MTU for AX.25. "w1xxx.foo.com" is the hostname of my peer. "sk0we-3" is an optional callsign of this new interface. The crossband digipeating to my radio interface would not work if I did not specify a callsign (other than sk0we-2.) That is all. Assuming that w1xxx has done a corresponding setup, I can now type connect ai0 w1zyx w1xxx-2 and the AX.25 frames will be sent to w1xxx.foo.com, where he will digipeat them on the w1xxx-2 interface, which hopefully is the 2m port. As long as both I and w1xxx use different callsigns on the radio and wormhole ports crossband digipeating is supported. One of the local TNC users will then be able to type Connect w1zyx Via sk0we-3, w1xxx-2 There is also a sequrity feature: The code will ignore AX.25 frames received from IP hosts that have not previously been enabled with the "attach axip" command. The changed source files are available at thumper.bellcore.com as pub/ka9q/incoming/axip.arc. 73, Anders ---- From: gvdg@cdc.com (Gerard Van Der Grinten) Date: Mon, 24 Jun 91 7:31:39 CDT Subject: Re: gateway problems Hello All, I uploaded nos_0605 again but whit a "small" mod in mailbox.c It appeard that with the timer restructure a 240L was changed in 240*1000L This was for the timer that flushes both sides of the gateway. Just wait 8 minutes and you see your output.... ;-) I changed it to 2 seconds (2*1000L) and all works normal. calling every 240 ms looks a little overdone to me... some other minor changes are also in. Good luck, Gerard. PS, it is on thumper in incoming untill moved and on wb3ffv and gvdgpc bbs. ----
