more ftp informations

[1/12] from: etienne:alaurent:free at: 20-Jul-2001 0:55

Hi, Rebolers, I'm working on an ftp client for my app. I saw the doc for Core 5.1, and I'm not able to write a correct code do read the structure of my ftp directory. The code is : all-files: copy [] system/schemes/ftp/passive: true foreach file read to-url chemin [ print file append all-files file ] where chemin is somethinq like ftp://user:[pass--my--site--com]/dir where dir can be an empty string or the path to a subdir I can find in all-files. I want to know infos about all files in all-files (is a directory, time, size, ...). Can you tell me if this code is ok? and how can I obtain infos about a file? (I know the info? instruction, but I don't know how to use it) I tryed : ftp-port: open to-url chemin forall ftp-port [ file: first ftp-port info: info? file print [file info/date info/size info/type] append all-files file ] close ftp-port but it doesn't work. Why ? Thanks to anybody witch can answer me. --- Etienne

Hi Etienne Have a look at ftpdemo.r in the View script library under ftp, it works with both View and Core. There are also a number of other ftp scripts under the ftp icon. The short answer is ftp dirs look and work just like dirs on your hard disk. -Larry

Re: more ftp informations - final slash

Put a slash on the end of your path (chemin): ftp://user:[pass--my--site--com]/dir/

> > where chemin is somethinq like ftp://user:[pass--my--site--com]/dir

It is a directory, very important to have the final slash.

still more ftp informations

hi, Rebolers, Larry, Anton

>(Anton) Put a slash on the end of your path (chemin)

I've done this. But it doesn't work like I want.

>(Larry)Have a look at ftpdemo.r in the View script library under ftp, it works >with both View and Core.

I had a look and I wrote my ftp client like all these examples. But I have always troubles : I can read an ftp directory. It's ok. But I can't have any information with info?. I tested with a known file and I obtained this error message : ** Script Error: empty? expected series argument of type: series port ** Where: dir-read? ** Near: info? ftp://user:[pass--my--site--com]/index.html (where user is my login, pass is my password, my.site.com is my ftp server) and, when I rescan the toplevel dir, I obtain this error message from REBOL and the ftp server : The connexion is not closed after the dir scan. Why ? is there toubles in the ftp protocol ? I tested also the ftpdemo.r file, and it worked fine (but ftp://ftp.rebol.com is an anonymous server here)

>(Larry)The short answer is ftp dirs look and work just like dirs on your hard >disk.

Ok. How can I change the current directory ? (with files I use change-dir) --- Etienne

Re: still more ftp informations - missed something

I missed to complete my Email : and, when I rescan the toplevel dir, I obtain this error message from REBOL and the ftp server : ** User Error: Server error: tcp 530 Already connected ** Near: foreach file read to-url chemin

funny, that the error I get when I scan an empty ftp dir with permissions! I guess this doen't help, but it might give you clues in your troubleshooting... -Max

Re: still more ftp informations - missed something

The ftp scheme caches connections to speed up directory listing etc. This could be confusing things. You can set the number of cached connections to 0 or 1 somehow... I think it's system/schemes/ftp/cache-size, which is 5 by default. This means up to 5 cached connections are open. Try also from a fresh rebol. Other people have had this kind of trouble on this list, I'll have a look. Holger has explained it all before.

I set system/schemes/ftp/cache-size to 0, and my script runs ok now :-) Thank you.

Where can I find the Holger explanation ? I had a look in the mailing list, and I didn't find it. How can I check if I have access to a particular directory ? (in one directory on my ftp server, I get : ** Script Error: ** User Error: Server error: tcp 550 ./mysql/: Permission denied) --- Etienne

Thank

> you.

I had the same problem. Worked with one ISP not another. It turned out that the one with the problem was allowing only 3 connections before it failed. Once it failed I had to quit that Rebol session and restart a new one. When I set the cache size as you have done everything worked very smoothly.

This might be what you are looking for (lightly edited): http://www.codeconscious.com/rebol/rebol-net.html#UsingFTPrecursively Brett.

Well, you could always 'try: if error? try [read ftp://abcdef.com/adir/ ][ print "there was an error" ]

Oh ! yes ! I forgot I could use error?. Thank you. Bye --- Etienne
