I was surprised that it was really easy. It worked without any fuss when I had my router installed. > Anyway, what exactly is "MSS"? Maximum Segment Size. And because AosTCP wasn't able to negotiate this parameter there was a problem. BTW the WebDAV server on bluebottle.ethz.ch is down until I adapt it to the new Aos now running there. Some minor interface changes.

My guess is it could be the problem I encountered with Aos (Not even WinAos) when I changed to DSL (Meaning connecting to the gateway using Ethernet. I finally traced it to a problem with MSS in AosTcp.Mod which AFAIK will be solved with the new Aos at the end of the month.

New no.WebDAVClient.Mod
by edgar＠edgarschwarz.de 07 Jan '04

07 Jan '04

Hi Chris, I just wanted to inform you that I sent you a new no.WebDAVClient.Mod. I didn't get a blacklist warning yet so perhaps I can reach you again. But nevertheless. If you don't get the mail with the asciicoded file please tell me and I will try it on the mailing list :-( Now DCT.Get should should work.

System.Directory HyperDoc* == HyperDocTools.Obj HyperDocs.Obj HyperDocs.Panel HyperDocs.Tool All this stuff seems to be lacking documentation ? There is a mistaken idea that Panels replace documentation/Tools. Desktops.OpenDoc"http://URL" will fetch the file, if the server serves it. Apparently a file named *.htm(l) will automagically be converted to 'oberon rendering' and the original 'ascii string' will be lost. Perhaps n-o can also store the original 'ascii string' ? For <non>.htm(l) the file is storable as received. I think Oberon.Text : MIME = { ... "application/GZip" = tar.gz "text/html" = html "text/plain" = txt ... controls the actions ? > Given a URI to an http accessible directory, is > there any way to get a list of the contents rather > than a view of index.html? Interesting: http://www.complang.tuwien.ac.at/ is apparetly a directory, which probably contains several files. My guess is that if you address the server via the http protocol, you cannot see the directory contents. Perhaps because http originated for use with htm(l) ie. hyperlinking, where directory structure is 'redundant' ? I'll ask on Newsgroups: comp.os.linux.networking if I get answers to my other similar questions. > How are cookies handled?

Apparently cookies is stuff written to YOUR file by the server, and read-back by the server on later connections. == Chris Glur.

Edgar, es> HyperDocTools.Fetch "http://carnot.pathology.ubc.ca/" => carnot.html ~ Thanks. Will try that. es> AFAIK that's not a question of Oberon but server and protocol policy. With a HTTP server you aren't expected to get a directory listing normally. OK. The Anarchie application for the Mac appears to be getting a directory listing via http but really it is just sifting the addresses out of index.html. Anarchie does not list files which are not linked in index.html. es> OTOH with a WebDAV server a PROPFIND with depth>0 should give you a directory listing. So WebDAV really does subsume ftp!

NO WebDAV Problems blacklisted
by edgar＠edgarschwarz.de 03 Jan '04

03 Jan '04

Hi Oberoners, normally this would have been a private mail to Chris but alas ... there is a problem. So the payload needs a short prelude. If seems that my ISP (A big German one, hosting millions of domains) is blacklisted with dnsbl.sorbs.net because on 2.1.2004 there was 1 spam detected originating from them (IP 81.169.145.166). So I can't reach Chris by mail. I immediately sent a mail to my IPS. As I get a about 50 to 100 spams a day I sympathize with what SORBS is doing. If you have a look at http://www.edgarschwarz.de/spam you will find some files containing thousands of spam mail headers I collected the last months. I planned to create my private hall of fame of spamming mailserver IPs like SORBS and publish it there. But experiencing SORBS I have to reconsider my plans. OTOH I have a problem how SORBS is working. If I'm wrong in some facts please correct me. But that's the situation AFAIK. - We have Saturday now and I don't suppose somebody at my provider will read my mail before Monday. So the question is how long it takes until my ISP will react. In the meantime there will be perhaps trouble for thousands of customers which are innocent. This depends how many ISPs use SORBS. - I would like to get information on at least the complete header information of the last (In my case single) spam which caused the listing as a spammer. This also could give the ISP the information to look into the criminal act. - So perhaps you should differ between small and big ISPs. An ISP like mine who hosts millions of domains can't guarantee that once in a while one of it's customers is sending spam I guess. You are potentially hurting millions for punishing one. This is out of proportion IMHO. It begins with me wasting a lot of time having a look at dnsbl.sorbs.net and writing this mail :-( So that was the prelude. Now comes the payload. Hi Chris, at first I want to wish you a happy new year ! easlab(a)absamail.co.za wrote: > This starts filling in some questions - but from the 'bottom'. > I will write a skeleton HOW2 'from the top' - the way humans best learn. That would be nice to give me an example what you mean by: 'from the top'. A very rough skeleton would be okay. As extensive as necessary to give me the idea. > MODULE AosDNS; > (* Copyright GNU Public License 2003. > Author. Edgar Schwarz > Contents. Dummy to interface with NO NetSystem > Remarks.

I already saw it on the client side with Bluebottle. Will have a look also on NO. I suspect it being in connection Receive or Available. Unfortunately a problem which seems to depend on timing (E.g. processor speed, connection speed) > {HTTP Client : GET http://webdav.ethz.ch/nodav/src/no.AosDNS.Mod} > {Connection.Receive: size, min, read, res 4096 1 1 0} > {Connection.Receive: size, min, read, res 4096 1 237 0} > {HTTP Client : HTTP/1.1 200} > {HTTP Client : resHeader.contentlength = 671} > vor LOOP{Connection.Receive: size, min, read, res 4096 0 0 0} > {HTTP Client : reader avail = 0} > {Connection.Receive: size, min, read, res 4096 0 343 0} > {HTTP Client : reader avail = 343} Here seems to be the problem. It tells that data is available but it seems not to be read corectly. > {HTTP Client : Timeout: waited for 10000 ms} Thanks for your logs ! I will check it the next days.

Web usage

Considering that I'm often oblivious to the obvious, here are a few questions about Web usage. Are any of these answered in the Oberon Web pages? Given a URI to a file, is there any direct way of retrieving the file by http? I know about HyperDocTools.Fetch but it needs a link. Given a URI to an http accessible directory, is there any way to get a list of the contents rather than a view of index.html? How are cookies handled? I see the command HTTPDocs.ListCookies and wonder whether I should be using it. Thanks, Peter E. http://carnot.pathology.ubc.ca/

Hi are there more code contributions for Bluebottle like WebDAV that could/should go into the (new) AosContributions.zip for the next release ? If so, please contact me before January 15, 2004 to discuss the details. --Thomas
