FTP
« on: August 01, 2013, 06:25:42 pm »
I have a need to move some rather large files between two networks, by large I mean greater than 12GB.

The easiest way to do this is via FTP.  The problem is that I have not been able to discover an OS/2 FTP client that can handle that size of file, most clag out at 2GB.

Is there such an OS/2 FTP client that will do the job or do I have to look at some sort of kludge to get the job done?

There may be others but IBM did put a set out on testcase that support greater than 2G but then closed the PMR as a permanent restriction and later released an updated FTP server/client that did not have the 2G updates in it.  I am not sure now where to find the >2g cable ones but they are available.

I just used QFTP ftp://ftp.netlabs.org/pub/qtapps/qftp-1.5.2-os2.7z to transfer a 5.1 GB file. I am also using Peter Moylan's FTP server http://hobbes.nmsu.edu/download/pub/os2/apps/internet/ftp/server/ftpser1.35.zip at the other end. It did some very strange things during the transfer, but it did do the complete transfer, correctly.

FWIW, I usually use RSYNC http://hobbes.nmsu.edu/download/pub/os2/util/file/rsync-3.0.9-20120425-shl.zip to do transfers like that. SAMBA, with the SAMBA client http://svn.netlabs.org/samba, will also handle large files.

Hello, Ivan...

Allow me to make it easy for you:

OS/2 FTP Update with large file support.

Thank you all for the suggestions which I will try out tomorrow if it's not as hot as it was today (45 degree C outside and about 60 C inside because the AC is off for its yearly check).

I have the IBM FTP update for greater than 2GB files from testcase and so far it has died after transferring just under 5GB (maybe a standard DVD).

As I said these are larger than 12GB, actually 12.5GB to 25.8GB virtual machine files that my client now wants to put back in operation after the arson of last year.

There is no question regarding OS/2 and the need for a good FTP client; it simply does not exist.

Strange, really.

Filezilla used to work with ODIN, but has not done so in years, (though I have not tried it with the latest ODIN updates).

Also, the need for FTP has diminished since Webrowsers integrated FTP into themselves.

There is still a need, just a diminished one, hence fewer clients.

That's too damn bad! in my opinion for I use FTP everyday and would welcome a proper client.

Starting with 3.2.3 it supports large files but not sure on OS/2.

Andy, I've already tried ncftp and it appears to be stuck at the 2GB barrier on OS/2.  It did flag up a warning that it couldn't continue though which is more than the others did.

It now looks as if I will borrow a windows notebook and use FileZilla to transfer the files from the old server to it and then transfer them to a NAS box.  Then use SAMBA to transfer the files from the NAS to their new home.

I have to agree with Ben we do need a GOOD FTP client for OS/2 that has no restrictions on file size.

Just to verify I have the right information... you were using 3.2.5 without success?  I don't know that there were any previous OS/2 releases after the large file support was added.  I had 3.2.2 previous to this discussion myself and it wasn't introduced till 3.2.3.

Perhaps if we define what "good" means, somebody will take that information and create a "good" client. IMO we already have a "good" FTP server (Thanks to Peter Moylan).

My "requirements" would be:

1) Follows the latest RFC for FTP. I would assume that that would include large file support.

2) It works easily, and in the OS/2 way. Probably as a file system, similar to what SAMBA does, or even the way that Firefox does it (what is wrong with Firefox? I haven't checked, but I think it will handle files greater than 2 GB. I would assume that SeaMonkey does it the same way).

What else is there, that I haven't thought about? I admit that I usually use the old FTP-PM program for most things, and it does what needs to be done, quickly, and easily. I haven't used the version that supports greater than 2 GB files, but  would assume that it is the same as far as the user is concerned (whether it actually works, or not, is unknown to me - I must try it).

I should have mentioned that Firefox (and, I assume, SeaMonkey) will only download from FTP sites (and it does handle files greater than 2 GB), without some sort of add on to do uploading.

netdrive ftp plugin support >2GB too. I use it as ftp client in conjunction with LarsenCommander but can't remember if I ever tested it with >5GB. Server from Peter Moylan.

Edit: just tested with a 19GB file. Worked ok.

Seamonkey still shows having upload file under File - Upload File.

Thank you everyone for your helpful ideas, several of which have been noted down for possible future use.  I went the multi hop route and the VMs are now up and running in their new server.

Now another question.

During the course of trying various things I loaded the latest OS/2 version of firefox on the server and all went well.  That is until I found a picture of a circuit board I was interested in and clicked MB2 to bring up the save image menu.  On clicking ok firefox vanished - it did save the image though.  I tried it several times with different images all giving the same results.  I also get the same thing happening on other multi core processor boxes so the question is, is firefox SMP safe?

I am pretty sure that it is supposed to be SMP safe. I don't see the problem that you describe, although FF does have a few other, similar, problems (at least one is probably related to FLASH). I do have the latest ACPI installed (acpi-3.22.02.exe), along with the SMP updates for various things that were released with the recent ACPI updates (but have nothing to do with ACPI directly). Perhaps you need them?
