 Atheros is a horrible company? I thought they were rather well
 regarded. 

Clearly you're lucky by not encountering anything that's using atl1c
kernel module. That card was the reason alone I use backported kernel
on my laptop, and it has some hiccups even then.

And, back in the old days, stock Debian 2.6.18 suffered from the random
kernel panics then using atl1 kernel module. They fixed as far as I can
tell, but I have a good memory.


 And I've used a number of Trendnet products, and they've
 worked well for me - cheap, but did the job.

Trendnet's unmanaged 1Gb switches actually manage to process whopping
200 Mbps maximum. Heck, maybe they buy counterfeit ones where I work,
but somehow I doubt it.

Just a thought to make it easier since the old one's dvd burner no
longer works.

I suggest that you start with a full back up of both computers (with an
extra archival set stored off site).  Do you know how to do this?


David



The second machine is a clean install, actually a new install.  I have not
yet done it but ran into a problem getting to the CMOS on the new toshiba.
I do know how to do a back up but why back up a new install?

You asked for help at this list because you didn't know, for sure, how to
move data from the old computer to the new. It's clear to me that you have
gotten clear, step-by-step instructions, so ... something that you do may
be wrong for the very special case of a broken compute connected to a brand
new compute, which *MAY* allow the broken computer to clobber the system
files on the new computer. Do you have a way of re-installing on the new
computer if this happens? Are you sure? Or do you expect to take a damaged
computer back to the retailer who sold it to you and get a replacement.
Maybe check out that expectation with the retailer.

You asked for advice. I think you got some good advice that maybe you don't
want to hear. Maybe? The sad fact is that you cannot install Debian on a
computer that won't boot from an install CD because some drivers or whatever
have been damaged.

YMMV


OK, First of all the old computer is my Toshiba laptop that works just 
fine.  The only thing wrong is the burner.  This machine is 4 years old 
and I wanted a newer model.  When all my files are transferred off of it 
it will be GIVEN to someone who needs a working computer.


Second, the new machine is also a Toshiba laptop just a newer model.  I 
have had to download a different set of ISO's since the new machine is a 
64 bit and the old one is 32 bit.  That is what I was doing tonite.  
Tomorrow I will use USB sticks to copy my files to and install them on 
the new machine.


I don't know why you got snarky with me.  I was unsure if I could use a 
usb cord from one to the other.  After the explanation about master and 
slave my 64 year old brain kicked in and I understood why it could not 
be done.  I have found a way and I appreciate everyone's help.  I have 
stored this information in a file for future use since as the family 
matriarch and computer person I try my best to learn new stuff about how 
things work.  Again thank you all.

Or for the less mechnically-inclined, seeing that both laptops have
available usb ports, you might just copy the files from the old laptop onto
a USB flash drive, and then stick the flash drive into the new laptop.

 If so would I need a certain command to do it?

Once a network connection is established, I use scp as in

$ scp -pr top-of-tree username@host:

After the colon, relative paths are with respect to username's home.
-p preserves permissions, -r for recursion, but be aware that files

 ie,
 
 wired ~$ scp a-file fill-this-in-please:destination-file-on-laptop
 laptop ~$ scp a-file fill-this-in-please:destination-file-on-wired

First, you invoke 'ip a l dev eth0' on both hosts.
In the case the interface lacks 'UP' flag, you invoke 'ip l s dev eth0
up'.
Once both interfaces are up, invoke 'ip a l dev eth0' again, and search
for the strings that look like (on both source and target hosts):

inet6 fe80::2867:acff:fef1:968d/64 scope link 
   valid_lft forever preferred_lft forever

In this example, 'fe80::2867:acff:fef1:968d' is so called 'link-local'
ipv6 address of the host.

Next, you invoke from source host:

ssh target_host_user@target_host_ipv6%eth0

And, if everything goes well, you should see customary 'The
authenticity of host … can't be established' message.

To copy the needed files, you invoke from the source host:

scp -r directory_containing_your_files_here \
target_host_user@[target_host_ipv6%eth0]:source_dir

I.e, to copy /home/user/Documents from one host to another, use:

scp -r /home/user/Documents \
user@[fe80::2867:acff:fef1:968d%eth0]:/home/user

The definition of 'source' and 'target' hosts is left as an exercise
for the readers. 


Of course, there're more complex (but faster) ways to copy files,
but the basics are here.

No, that won't work. USB uses a master/slave model and both of your
laptops are masters. If you want to use USB you would have to use an
intermediate storage device.

If you have a home router or a switch with at least two Ethernet ports,
then the easiest way is probably to install openssh-server on one of the

What kind of files are you trying to transfer?  I was able to sync the photos 
on my wife's iphone via Shotwell despite the Trust pop up on the phone.  Just 
don't hit Trust during the sync or it will interrupt and possibly cause 
problems.  I wasn't able to browse the photos via Nautilus (I'm using Gnome) 
but I also didn't want to spend a lot of time on this.

File transfer between Debian Wheezy Xfce and iPad, iPod, iPhone

2015-01-02 Thread David Christensen


debian-user:

I would like to transfer files between Debian Wheezy Xfce computers 
(i386 and amd64) and iOS devices (iPod, iPad, iPhone).



On Debian, I have installed:

libimobiledevice-utils


When I connect the charging cable between an iPad Mini (Model A1489) and 
a USB 2.0 port on a Debian machine, dmesg indicates (SerialNumber redacted):


$ dmesg | tail -n 6
[  152.171793] usb 4-1.2: new high-speed USB device number 15 using 
ehci_hcd
[  152.266301] usb 4-1.2: New USB device found, idVendor=05ac, 
idProduct=12ab
[  152.266306] usb 4-1.2: New USB device strings: Mfr=1, Product=2, 
SerialNumber=3

[  152.266309] usb 4-1.2: Product: iPad
[  152.266311] usb 4-1.2: Manufacturer: Apple Inc.
[  152.266313] usb 4-1.2: SerialNumber: 




On the iPad, a pop-up dialog appears:

Trust This Computer?
   Your settings and data will be
accessible from this computer when
connected.
Trust  Don't Trust


When I touch Trust, there is activity in the icons in the upper-right 
corner of the iPad display, and then the pop-up dialog appears again; ad 
infinitum.



Any suggestions?


TIA,

David

 The point, however, is that there is no file transfer method that
 meets her requirements.
 
 1. No dedicated server (no web, no sftp, no ftp, NFS, Samba, etc).
 2. No usernames/logins (no sftp, scp, no ftp, etc, see above)
 3. No chat protocols (no IM, no IRC)
 4. No external 3rd party service (dropbox, etc)
 5. No email (messages are too large).

IMHO, it seems, as he break some computer (or get access without owner's
knowledge) and he want upload files to it now.

No download is required, because there is no one, who will be download
the file.
No dedicated server, to regular (not expert) user have trouble find it.
No mail nor IM, because here is no regular account on another side...
No external service, because it need some interaction...

I wasn't suggesting ssh as an application. I was recommending ssh as

or FileZilla.

But others are already making this point so I'll sit back and continue

 Woof (Web Offer One File) tries a different approach. It assumes that 
 everybody has a web-browser or a commandline web-client installed.
 Woof is a small simple stupid webserver that can easily be invoked on
 a single file. Your partner can access the file with tools he trusts
 (e.g. wget). No need to enter passwords on keyboards where you don't
 know about keyboard sniffers, no need to start a huge lot of
 infrastructure, just do a
 
   $ woof filename
 
 and tell the recipient the URL woof spits out. When he got that file, 
 woof will quit and everything is done.

 Requires Python to run, and obviously needs to run on a machine where 
 people can access the resulting URL (DNS listing, IP address
 accessible to the outside world, etc.).
 

Woof is excellent! Woof's also in the debian package repositories, as
is fex (from your previous message). Thank you for finding these, try
as I might I was unable to find any programs that do this from my own
searches.

Someone in another area of the thread commented that I wanted to send
a file rather than make one available for download... I should have

Yes, the XKCD you posted sums up what I've found kind of silly for

 It isn't part of the standard desktop configuration.
 
  The original poster said the want to send a file to someone, as

  file from one linux machine to another, scp is a pretty
  straightforward way to do it from the command line, and scp runs
  over ssh.
 
 I don't think the OP really knows what he needs to do to achieve his
 ends. People are often lax in not distinguishing between making a file
 available and sending it.
 

Yes, I'm sorry for not being clearer. The difference really *is*
important in cases like this. Making a file available would be
perfectly all right; this is probably what I *should* have meant by one
person --listening and the other connecting to the listening machine,
but have it be --listening as in waiting for a request for download.
Miles suggested Woof in another area of this thread

  Not sure why you consider ssh to be over the top - anybody in
  their right mind turns off telnet and ftp as the first step in
  securing a new installation - in favor of ssh and sftp.
 
 Telnetd and ftpd are not installed on a new installation, so how do
 you turn them off? telnet and ftp are installed but you do not have
 to use them. ssh is overkill for the OP if he only wants to make files
 available for download. If they contained state secrets I might go
 along with you and advise the more complicated and time-consuming
 procedure of setting up ssh on both machines is worth it.
 

Most of the time I just want the data moved (whoops, *copied*) from
host to host, with little concern for encryption. If I did want
encryption it would probably be with GPG on the file itself. :)

I am technically able to reach my local computer from outside the local

forwarded to the correct subnet address.

 Implicit in my reply was that assumption. It is what I am accustomed
 to, even though my own ISP offers the facility you describe. Thank
 you for pointing out how different ISPs allocate addresses. I will
 try to remember that a router may not have a routeable IP address.
 Given a choice of ISPs, I'd not choose one who imposes what you
 describe.
 

But although I technically *can* do this, very effectively, my ISP gets
pissy if I do it very much at all. :( This whole thread is really
because I want to do one-off data transfers without running a web
server and without necessarily having to worry about persisting
availability of data that might be being downloaded. If that happens I
could be disconnected (though probably temporarily).

 GPG encrypted file(s) + torrent with public tracker?
 I have used that method sometimes.
 

And although a great program has been recommended (Woof), I think I may
like this method better, at least when the files are large enough. Two
reasons:

1. My ISP can get mad if I send too much data up through my connection,
   complaining that I'm running services. If I throttle the upload,
   it's not an issue.

2. If we lose connection for some reason, the download does not have to
   restart! At least with Woof, I believe that that would be necessary.

Plus GPG is awesome! I may use GPG with one of the other make a file
available for download methods in the event that the other person can
be expected to decrypt it! :)

 Yes. A proper server (http, ftp, ssh) would satisfy this requirement
 but you've excluded those with #1, #2. If your PCs can have Internet
 facing ports configured, I'd go for ssh/rsync every time.
 
 1.  One (or both) of you configure your router/firewall to accept
 inbound TCP connections from (say) port 10022 and route them to your
 Linux-based PC on port 22. If you can't redirect port 10022 to
 port 22 then just forward port 10022 and create a firewall rule on
 your Linux-based PC to rewrite inbound requests on 10022 to local port
 22. (Come back here if you need help with that.)
 
 2.  Consider the use of DDNS services such as those provided by
 dyndns.org to make your IP address available by name to your friend.
 
 3.  Install the openssh-server package
 
 4.  Configure /etc/ssh/sshd_config, adding an AllowGroups line such
 as this:
 
 AllowGroups sshuser
 
 5.  Put your and your friend's user accounts into the sshuser group:
 
 groupadd sshuser
 usermod -a -G sshuser YOURUSERNAME
 usermod -a -G sshuser YOURFRIENDSUSERNAME
 
 6.  Make sure that your password, and your friend's password on your
 machine, is sufficiently complex that others are unlikely to
 guess it.
 
 7.  Use rsync (over ssh) or sftp to copy the files. Remember to tell
 them to use port 10022 (or whatever you decided in #1) instead of the
 default port 22.
 
 Chris
 
 

In the event that the other person is capable of ssh/scp, I will
probably configure a setup like this. Thank you for the how-to!! Very
helpful. I don't mind ssh/scp, but most people I know don't know how
to use that sort of thing at *all*.

Thank you!

 That said, there have been a number of suggestions towards modifying
 the OP's requirements and I'm interested in seeing the reasoning
 behind the requirements themselves.  Aubrey hasn't replied yet and I
 think there's value in giving her an opportunity to respond, clarify
 and perhaps narrow her requirements, and allow us to provide better
 advice.  The fact is, with the requirements set as they are, there is
 no possible solution (see below) to her problem.

My reasoning may not be as well-thought-out as I first thought, as
pointed out directly and indirectly by many people in this thread. ;)

In the end I think I may be using Miles' suggestion of Woof;
it is essentially a one-off ad-hoc HTTP server implemented in python.

 (Yes, I did see someone suggest nc (possible alternative: socat).
 While that *does* meet the OP's initial set of requirements, that's
 not really much of a solution...) ;-)
 

Surprisingly netcat might very well be a perfectly reasonable way to
go... I will look into socat while I'm at it, thank you.

 why would they have been posting to this list?
 
FileZilla is available in Debian (in case you didn't know).  I only
recommended it because it's a popular name.  And for beginners, I think
a GUI FTP application is easier than rsync.

 In the event that the other person is capable of ssh/scp, I will

 to use that sort of thing at *all*.
 
Aubrey,

If you do set up an ssh server, your remote users can use an SFTP client
to access it.  FileZilla or GFTP are two that come to mind.  That may be
easier for your users than command-line scp or rsync.

I don't get it.

Do you need a system for sending big files to a recipient or something 
else (such music streaming)?

For just sending larger files I would use an external public service 
(that you can mount by yor own means or one of those you can share with 
zillion users, e.g., Sendspace, Google Drive, Dropbox, etc...) but this 
seems to be confronting with your first point :-?

You don't give a reason but you are being unnecesarily restrictive by
stipulating this condition. A small web server such as webfs takes all
of five minutes to set up and gives you what you want with the advantage
that your friend can use a browser to transfer the files.

Do you have a have public IP address (either IPv4 or IPv6)? If
that is not the case, you will need a third party in order to
establish the connection.

Could you explain why you don’t like http/ftp? They can also be used
by ‘non-proper’ or very small servers. Personally, I keep around a
small lighttpd installation for that use case.

However, you might also want to have a look at ‘servefile’ [1] which
basically acts like nc from rjc’s mail, but uses the HTTP protocol.

There are some nice aspects to this script. Being able to use a browser

worse than install and use it. It looks like it would install on Squeeze

Thanks for drawing servefile to our attention.

Hello Debian users!

Sometimes I have the need to send files that are too large for email to
a friend directly (such as recordings of music I am working on, or
similar projects). I'm wondering if there is a program that I could use
for direct transfer, hopefully with these qualifications:


If you're going to be sending to a friend, the real issue is getting 
your friend to install something and use it, which makes it a question of:

- what, if anything, are your targets willing and able to install
- how complicated things get to use
- whether someone has to be at the other end to receive the file, or 
whether it's automatic


In this regard, I think all three of your requirements get in your way 
of doing something easy and practical.


1. Not a proper server (http, ftp)


Pretty much all modern o/s's come with both a web server and ftp 
pre-installed.  It's a matter of turning them on, and configuring them 
(if your target is running a GUI, it's usually a check box).


ftp to an anonymous account is probably the easiest to set up

if your target is running unix, I'd suggest simply ssh + scp -- again 
they're already there and it's a simple command to transfer something



2. No usernames? (scp, rsync)
seems like a bad idea - if you were sending me something, I sure 
wouldn't want to expose my machine to the world, just so you can send me 
a file



3. Preferably does not require a chat protocol (XMPP, IRC's DCC)


well, dropping a file into a chat session is a really easy way to move files

Now... what I do in this case is mozy over to filmail.com - one of 
several services that provide a simple (and free) file mailing service:

- go to the web page
- enter sender/recipient email addresses
- enter file path (or browse to file path)
- send

The system uploads your file, and sends an email that includes a link.  
The recipient gets the email, clicks the link to download the file.  All 
quick, easy, no software install.


If you don't want to rely on a third party, there are packages that you 
can install on your machine to do similar things - essentially sending a 
one-time link my email, that allows the recipient to download the file 
from your machine.

No. I was not referring to a static but to a public IP address. If
the user has a public, i. e. internet-routable IP address, everything
is fine, even if it is not static. However, if the user sits behind a
NAT or something similar that blocks incoming connections, a third

Lacking more information from the OP, speculation is all I can do,

Yes. A proper server (http, ftp, ssh) would satisfy this requirement
but you've excluded those with #1, #2. If your PCs can have Internet
facing ports configured, I'd go for ssh/rsync every time.

1.  One (or both) of you configure your router/firewall to accept inbound
TCP connections from (say) port 10022 and route them to your
Linux-based PC on port 22. If you can't redirect port 10022 to port
22 then just forward port 10022 and create a firewall rule on your
Linux-based PC to rewrite inbound requests on 10022 to local port
22. (Come back here if you need help with that.)

2.  Consider the use of DDNS services such as those provided by dyndns.org
to make your IP address available by name to your friend.

3.  Install the openssh-server package

4.  Configure /etc/ssh/sshd_config, adding an AllowGroups line such
as this:

AllowGroups sshuser

5.  Put your and your friend's user accounts into the sshuser group:

groupadd sshuser
usermod -a -G sshuser YOURUSERNAME
usermod -a -G sshuser YOURFRIENDSUSERNAME

6.  Make sure that your password, and your friend's password on your
machine, is sufficiently complex that others are unlikely to guess it.

7.  Use rsync (over ssh) or sftp to copy the files. Remember to tell them
to use port 10022 (or whatever you decided in #1) instead of the
default port 22.

I have a similar, if not exactly the same, requirement as the OP. My
daughter has a desire for a bit of entertainment every so often. She
types http://my_IP:8000 in her browser (https is also available), gets a
directory listing, inputs a username and password and downloads the file
she wants. A quick process, using a familiar, no fuss routine. The URL
is also bookmarked.

There appears to be no advantage in using sshd in this situation. The
idea of having to guide her through configuring a router and using ssh
(on a Windows machine, incidentally) doesn't bear thinking about for one
thing.

I was going to let it go but the more I look at what you say the more I
wonder what you are talking about. Debian is a modern OS but, whenever I
have put it on a computer, it has never come with a web server or ftp
server. 

 ftp to an anonymous account is probably the easiest to set up

Could be, depending on what you want to set up. The deciding factor,
however, is how easy it is for the person who wants to download a file.

 if your target is running unix, I'd suggest simply ssh + scp -- again  
 they're already there and it's a simple command to transfer something

Target? You mean the machine which is downloading? Even if they were on
Debian, the use of ssh is over the top.

 2. No usernames? (scp, rsync)

 seems like a bad idea - if you were sending me something, I sure  
 wouldn't want to expose my machine to the world, just so you can send me  
 a file

I do not understand that. He is making something available. You download
it. How is that exposing your machine to the world? You do it all the
time. He doesn't require a username or password - that's his problem,
not yours.

Brian, you seem to be assuming that the router has a public IP (on the WAN

Implicit in my reply was that assumption. It is what I am accustomed to,
even though my own ISP offers the facility you describe. Thank you for
pointing out how different ISPs allocate addresses. I will try to
remember that a router may not have a routeable IP address. Given a
choice of ISPs, I'd not choose one who imposes what you describe.

Telnetd and ftpd are not installed on a new installation, so how do you

them. ssh is overkill for the OP if he only wants to make files

That's just it. Using anything *other* than ssh is a waste of time
and effort most of the time as ssh requires no setup and effort to
use out of the box not only in Debian but any modern Linux/Unix.
*Everything else* requires effort to setup and use.

The point, however, is that there is no file transfer method that
meets her requirements.

1. No dedicated server (no web, no sftp, no ftp, NFS, Samba, etc).
2. No usernames/logins (no sftp, scp, no ftp, etc, see above)
3. No chat protocols (no IM, no IRC)
4. No external 3rd party service (dropbox, etc)
5. No email (messages are too large).

There is no way to get a file from her machine to her friend's machine
without violating at least 1 or more of these requirements (at least
over a network). All I can suggest is a USB stick/CD-R and postal
mail.

That said, there have been a number of suggestions towards modifying
the OP's requirements and I'm interested in seeing the reasoning
behind the requirements themselves. Aubrey hasn't replied yet and I
think there's value in giving her an opportunity to respond, clarify
and perhaps narrow her requirements, and allow us to provide better
advice. The fact is, with the requirements set as they are, there is
no possible solution (see below) to her problem.

(Yes, I did see someone suggest nc (possible alternative: socat).
While that *does* meet the OP's initial set of requirements, that's
not really much of a solution...) ;-)

Just for reference... installing PuTTY and/or PSCP and/or PSFTP on 
windows is pretty darned trivial - download the .exe file and you're 
done.  Takes about 10 seconds (I carry PuTTY on a memory stick for 
access to our server farm, from pretty much any nearby machine).  Or 
install FireFTP as a FireFox plugin.

As I mentioned earlier - the easiest solution I've found, for both 
sender and recipient, is a file upload/mail service like yousendit or 
filemail.


After a LOT of looking, I managed to find a GPL package that does the 
same thing:

http://fex.rus.uni-stuttgart.de/
- GPL'd source version: http://fex.rus.uni-stuttgart.de/fex.html
- Debian Package: http://packages.debian.org/sid/fex (this is a Debian 
list after all!)

- hosted version: http://fex.rus.uni-stuttgart.de/fup

And... XKCD captures the whole problem perfectly at

Re: Programs for direct friend-to-friend file transfer?


here's another interesting one:
http://www.home.unix-ag.org/simon/woof.html

From the description:

---
Woof (Web Offer One File) tries a different approach. It assumes that 
everybody has a web-browser or a commandline web-client installed. Woof 
is a small simple stupid webserver that can easily be invoked on a 
single file. Your partner can access the file with tools he trusts (e.g. 
wget). No need to enter passwords on keyboards where you don't know 
about keyboard sniffers, no need to start a huge lot of infrastructure, 
just do a


 $ woof filename

and tell the recipient the URL woof spits out. When he got that file, 
woof will quit and everything is done.

--

Requires Python to run, and obviously needs to run on a machine where 
people can access the resulting URL (DNS listing, IP address accessible 
to the outside world, etc.).

 Yes. A proper server (http, ftp, ssh) would satisfy this requirement
 but you've excluded those with #1, #2. If your PCs can have Internet
 facing ports configured, I'd go for ssh/rsync every time.
 
I agree with using ssh, but I'd configure it to force sftp upon login
like this:

 1.  One (or both) of you configure your router/firewall to accept inbound
 TCP connections from (say) port 10022 and route them to your
 Linux-based PC on port 22. If you can't redirect port 10022 to port
 22 then just forward port 10022 and create a firewall rule on your
 Linux-based PC to rewrite inbound requests on 10022 to local port
 22. (Come back here if you need help with that.)
 
That's a good idea, in my opinion, to not expose port 22 directly.  It
reduces the effectiveness of script kiddies.

 2.  Consider the use of DDNS services such as those provided by dyndns.org
 to make your IP address available by name to your friend.
 
Agreed.

 3.  Install the openssh-server package
 
Agreed.

 4.  Configure /etc/ssh/sshd_config, adding an AllowGroups line such
 as this:
 
 AllowGroups sshuser
 
It's simpler to just AllowUsers user1 user2 user3

 5.  Put your and your friend's user accounts into the sshuser group:
 
 groupadd sshuser
 usermod -a -G sshuser YOURUSERNAME
 usermod -a -G sshuser YOURFRIENDSUSERNAME
 
This won't be needed if you follow my advice on step 4

 6.  Make sure that your password, and your friend's password on your
 machine, is sufficiently complex that others are unlikely to guess it.
 
Always a good idea, but the risk is lessened by forcing sftp (and not
posting any sensitive data on the sftp site)

 7.  Use rsync (over ssh) or sftp to copy the files. Remember to tell them
 to use port 10022 (or whatever you decided in #1) instead of the
 default port 22.
 
Instead of using rsync, use FileZilla or another FTP client.  But first
you must add this to your sshd_config file:

Subsystem sftp /usr/lib/openssh/sftp-server  #this line probably already exists 
-- check for it
Match user user1,user3  #you can omit this if you want it to apply to all users
ChrootDirectory /srv/sftp_folder  #this folder must be owned by root and 
writeable only by root
X11Forwarding no
AllowTcpForwarding no

Programs for direct friend-to-friend file transfer?

2012-06-01 Thread Aubrey Raech

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

Hello Debian users!

Sometimes I have the need to send files that are too large for email to
a friend directly (such as recordings of music I am working on, or
similar projects). I'm wondering if there is a program that I could use
for direct transfer, hopefully with these qualifications:

1. Not a proper server (http, ftp)
2. No usernames? (scp, rsync)
3. Preferably does not require a chat protocol (XMPP, IRC's DCC)

- From what I can find it seems like XMPP would probably be the best bet
for this... is there no program you can run with something like a
- --listen to listen for a connection on one end, and then run the
program with the destination IP from the other? Something along those
lines?

Any and all advice/recommendations are appreciated!

file transfer from removable flash memory: time stamps and case

2010-05-28 Thread H.S.

Hello.

When I copy files from a flash memory (inserted in a USB card reader) to
my Testing desktop, I notice that the filenames are upper case and the
time stamp of the transferred files is the time they were transferred
and not when they were originally created.

How do I avoid these and get lower case filenames and original
timestamps? The flash memories are all vfat.

Thanks.

As per filename case, if you are running GNOME you can tweak that under 
start/system tools/configuration editor and navigate to system/storage/
default_options/vfat then set the value mount_options to 
[shortname=lower,uid=] that will cause all the files, despite their

OTOH, I see the right time stamp for the copied files :-?

as a flash memory) are all of the same time when they were actually
transferred. I will try again though.

1. Add the option shortname=winnt (or maybe some other shortname=
   values (see the manual page for the mount command)) to your mount
   options (in /etc/fstab, your command line, or whatever on your system
   mounts the filesystem on the flash memory).

2. If you're using the cp command to copy, consider the -p or -a
   options.  Since you're probably dragging and dropping in a file
   manager, you'll have to find that file manager's equivalent of
   cp's -p and/or -a.

Okay, I will try to search how this option is related to KDE.

Yes, I am using Dolphin for the drag and drop. If I can't find the
equivalent of -p or -a of cp commands in Dolphin, I think using cp
on cli might be the next option.

Thanks.

size problem of large file transfer over https

Hello,

I have a large data tar file of 4.4 GB. I have made it available over
https to be downloaded by the recipient. This is on a Debian Sid, 2.6.26
kernel and the partition is ext3.

When the remote user clicks on that download link, his browser is
showing the file size to be only around 130 MB. The client is a Windows
XP machine where the drive is NTFS formatted.

I am not well versed with apache server. Have it somehow hit a limit set
in the https server? If not what gives?

Thanks.

It's probably not a problem with the Apache server.  Instead, it is probably 
an issue with the Windows client.  The size reported by the Apache server is 
probably overflowing a 32-bit unsigned integer.  I'm pretty sure the NTFS 
supports 4.4G files, but that doesn't mean that every client (or server) is 
prepared to see a size that large.

Could you post the results of an HTTP HEAD request for the file?  I'm 
particularly interested in what Apache is sending as the value of the 
Content-Length header.  If you don't have another tool in mind for this, 
wget should be able to show you these headers.

If the Content-Length is correct, it is a problem client-side.  If the 
Content-Length is incorrect, it is a problem server-side.

I gave it a shot myself with my own machine using Iceape browser and I
also see the size as around 132 MB. I am trying from a Debian Testing
machine (ext3 partition).

Here is the request I see if I try using wget:
.

.
HTTP request sent, awaiting response... 200 OK
Length: 138256384 (132M) [application/x-tar]
Saving to: `datafile.tar'

18% [==   ] 25,657,344  11.1M/s  ^C


So something is messed with the server. How do I go about checking what?

Thanks.

I am also not an expert in Apache, so this is about as far as I can take 
you.  You should probably scan the Apache documentation for options 
pertaining to big, large, or huge files.  (Or perhaps they are more 
technical and use the phrase 32-bit or 4G.)  While you are doing that I'd 
hit an apache-specific list (and hope someone better versed replies here) 
with your query.

If you don't get any (more) traction on the mailing lists and are fairly 
sure your setup is correct, so ahead and file a bug (if one doesn't already 
exist).

Right. Thanks for your help. I am going to check apache docs now.

Well, I split the tar file to smaller chunks of 680M each (using the
split command).
$ split -d -b 680M /tmp/datafile.tar  datfile

Now I am able to download the files successfully from the apache server
machine using wget. Apache reports the correct size now of Length:
713031680 (680M)

The only problem is that the remote user uses Windows and will need a
method to join them together back to the tar file. In Linux, one would
just cat them together. In Windows, I have searched google and found the
following will work on a command prompt:
copy /b datfile* datafile.tar /b

where datfilenn are the split files. This was from:
http://elliottback.com/wp/combine-split-files-in-windows/

The tar file then can be opened by using 7-zip in Windows.

Of course. That -d tells split to number them sequentially. There are
only seven parts and they are listed in the right order.

Thanks.
