Using FTP for debugging lower level modules might also lead to insights into the longstanding problem of the Oberon FTP system to work consistently with other FTP implementations (IE, IIS, Firefox FireFTP). > 1.

Systematically debugging
by Stefan Salewski 17 Feb '06

17 Feb '06

Hello, i wonder how to systematically debug Bluebottle software if strange errors occur. Current probleme: I have currently two computers on my desktop, the old one running Bluebottle, the new one running Linux. I tried some communication between them, starting FTP-Server or VNC-Server on the Bluebottle box. There exist a strange error, communication breaks after transmission of a small multiple of 524 Bytes from Bluebottle server to Linux box. Transmission in the opposite direction seems to work. Transmission from a far away linux box at university of Hamburg to my Bluebottle box at home work most time (not always), transmission from my Linux box to a Bluebottle box at ETH (VNC-Server) seams to work too. If transfer from my Bluebottle box breaks, a serious errors must have been occured. Bluebottle box is periodically death for a few seconds (cant move move pointer), ping to bluebottle box doesnt work anymore, and System.Reboot works only with delay, after calling it multiple times or is not working at all. So I think this is not just a problem of TCP-Pakets with wrong headers, but something serious going on on bluebottle box. Well, I dont really need connectivity between the two boxes, so one method to solve the problen may be just to wait until ETH can reproduce it and maybe fix it. In the last days I spent some hours investigating the bluebottle code, especially module AosTCP.Mod. But the bug may be hidden in other modules, 3Com90x.Mod, AosNet, ... Finding such a bug in an multitasking or active object system is not easy. The advantage is that i can trigger this error each time I start a ftp-server at my Bluebottle box, start ftp-client on my linux box, connect and execute command get with a file larger than 500 byte or do command ls displaying multiple files. (Transmission breaks after transfer of 524 or 1048 Bytes, this is a blocksize in module AosTCP.Mod so my first gues was that the error is in this module. But this module contains much low-level code, I cant easily see an error. And maybe the data-transmission of module AosTCP.Mod just triggers the error, but is not containing the error itself.) Has somebody a systematic debugging strategy for non trivial errors like this one? Best regards Stefan Salewski

When I got DSL I didn't look into the problem anymore. Daniel will look at PPP now. But I fear that he won't be any help to Chris' problems because as I understand it he doesn't want to use PPP over a serial port. But you never know. Cheers, Edgar

When I want to edit one char. of a previous post and re-send I can't find out how to. Can any one tell how ? Yes I've been investigating rfc2554.txt Every test run costs a call-charge. Does any one know of a 'like echo mail server' where I can see if/what I've sent, since the authentication only applies to 'external/remote' domains. Ie. self posting shows nothing. Later I'll post some of the traces from the relevant TextMail.send . Starting from rfc2554.txt 's Examples: S: 220 smtp.example.com ESMTP server ready C: EHLO jgm.example.com S: 250-smtp.example.com S: 250 AUTH CRAM-MD5 DIGEST-MD5 C: AUTH FOOBAR S: 504 Unrecognized authentication type. C: AUTH CRAM-MD5 S: 334 PENCeUxFREJoU0NnbmhNWitOMjNGNndAZWx3b29kLmlubm9zb2Z0LmNvbT4= C: ZnJlZCA5ZTk1YWVlMDljNDBhZjJiODRhMGMyYjNiYmFlNzg2ZQ== S: 235 Authentication successful. where S:\C: is the server\client talking, it seems that the server initiates the protocol ? In my case I see\trace : "250 absamail.co.za Pleased to meet you" which sounds like the equivalent of the initial "server ready" of the example. But I guess it MUST be a '220' mesg ? In the example, apparently the type of authentication negotiated by S: & C: is 'CRAM-MD5' ? I'm hoping that M$-outsp00k, gives just the pop: ID & pswrd. In order to isolate the complication of the parsing of these 2 parameters, I just hard-code them into TextMail.send [initially - using successive refinement ;-]. here's a partial trace of what my server says:- 250 Sender OK 250 Recipient OK 250 Recipient OK 571 Remote sending only allowed with authentication! agora(a)dna.affrc.go.jp not found for the following post:- To: crglur(a)absamail.co.za Cc: easlab(a)absamail.co.za Cc: agora(a)dna.affrc.go.jp Subject: get URL = NOtst send http://www.voanews.com/english/Science/index.cfm where the first 3 traces are OK because the first 2 URLs are internal. And "agora(a)dna.affrc.go.jp not found" is a trace from the source-code: ] SendCmd(Mail, "RCPT TO:", rcpt); Response(Mail, s); ] IF s[0] # "2" THEN String(rcpt); String(" not found"); The var-par 's' is the string: "571 Remote sending only allowed with authentication!", but I don't understand how the mail server would be expected to know that "agora(a)dna.affrc.go.jp" was unknown [independant or any send-authorisation issue]. I though that task would be handed-off to routing & DNS to determine ? == Chris Glur.

Re: AW: [Oberon] Successful USB boot

-- Aubrey McIntosh, Ph.D. >>> staubesv(a)student.ethz.ch 1/29/2006 8:10 AM >>> Hi, >The Jan 24th Crazy Fresh release boots from a 1GB Toshiba flash memory stick. >The release does allow re-creation of the boot file AosUsb.Bin. Cool! >There are a few issues, but they may be due to my odd Configuration strings. What issues? The only configuration string you need extra for USB booting is "BootFromUsb=1" which forces the USB storage driver to block until a USB storage device has been found and put into the AosDisks.registry. Did it work with all host controller drivers linked into the kernel (AosUsbUhci, AosUsbOhci & AosUsbEhci), or have you only linked one if them into the kernel? Cheers, Sven Stauber Well, I'll start with the release CD. I have a HP/Compaq D530 SFF (DC578AV) computer with internal DVD/ROM, PS/2 keyboard, and Logitech USB Mouse, and LiteOn CD burner model USB SOHR-5239SX. 1. This appears to be a dual processor machine. 2. Frequently, it does not complete the boot process, and re-boots. On older releases there are a lot of interrupt traps, and presumably the internal DVD/Rom and Bluebottle don't play well together. 3. It is necessary to add the configuration string Boot6=AosUsbMouse.Install to be able to use the mouse. 4. When the Lite-On USB burner is connected, there are some configurations that never allow the mouse to work, and some which occasionally allow the mouse to work. xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Status Mouse LiteOn fail USBHC1/1 USBHC1/2 fail USBHC1/2 USBHC1/1 fail USBHC0/2 USBHC1/2 sporadic USBHC0/2 USBHC1/2 sporadic USBHC0/1 USBHC0/2 5. When I edit the configuration strings, I have to type very quickly: if the DVD/ROM motor stops or slows, the system will hard reboot. 6. After the system boots, I typically open either a BB editor, or Oberon. When I do this, the system acts as if I have pressed the meta key---if the mouse bumps the edge of the screen, it scrolls. When I depress and release the meta key, the system returns to good behavior. I have the results of PCITools.Scan, and the System.Log saved to USB stick, but was not going to post them unless they might be useful.

Chris & Daniel, cg> Q- does anybody in the 1st world still use dialup ? Yes. At home and at the city apartment. dk> We will not use PPP with old analog modems, but with gprs ... I view the exclusion of analog modems as an unfortunate design decision. Imagine that you exclude 5% of potential users because of lack of modem support. Then exclude another 5% for lack of printer support. Then another 5% for failure with a certain FTP server ... and so on. The net effect is that by relatively small economies in implementation you exclude a large population of potential users. Conversely, relatively small investments in implementation can allow a significantly larger audience. Regards, ... Peter E. Desktops.OpenDoc http://carnot.pathology.ubc.ca/

> My ISP [without prior notice] disabled my email send ability. > Unless I used M$> Outsp00k. > > Now it's open again. > Perhaps not for long ? No that's wrong ! Email posting [without error 517] was only enabled because of the pop-authentication which was done just before the send request. As may be reasonably assumed, the transmit authentication, uses the same pair [ID & password] as the receive. So by just doing receive authentication before transmitting, it seems ok. It's nice the way N-O has all the facilities transparently available just below the surface, that can be easily re-arranged, instead of hidden deep behind cartoons & eye-candy ? == Chris Glur. Now I'll see it I can post this ?

Since the highest technical specification is that "it must work with today's flavour of WINxx" I/we need to know what type of send-authentication Outlook uses ? I had another look at TextMail.Mod [which now I remember I previously modified to handle my (given to me) ID of > 16 chars] The code is well structured for modifying/extending. And if I could find out which type of send-authentication Outlook uses, the appropriate RFC could make it doable. Q- does anybody in the 1st world still use dialup ? Thanks for any info. == Chris Glur.
