Ubuntu Networking :: Samba Crashing When Reading / Writing Many Small Files?

Mar 18, 2010

Samba seems to crash and come back after some seconds if I copy a lot of small files in a short period of time over the network. How do I fix it?

I have Ubuntu 9.10 Server 64bit running on a D945GCLF2 board sharing two 1TB ext4 formatted HDDs to my Windows PCs using samba. I've been having an issue with reading or writing files through samba. It happens during copying operations or checksumming, anything that reads or writes MANY small files in a small amount of time. I am pretty sure the problem has to do with my server because the server has run on two different LANs in different homes and will crash from activity with any of several other PCs. There is no crashing if I access the files through SSH, although when I do that the max transfer speed is less than 1MB/s.

When I induce the crashing, there is absolutely no output to the server terminal.

As an easy access example of something that will crash samba, extracting Cinebench R11.5 to the server will do the job. It always fails.

Ubuntu :: Pc Acting Slow When Reading / Writing Files From _ Onto Disk - Is That Normal?

Sep 27, 2010

Whenever I am busy reading or writing large files, or large sum of files, my computer is unresponsive. Screens are getting greyed-out and I just can sit there and wait until the reading/writing is done.
This is not caused by the CPU which is overstressed because it is not. Look at the attachments and you will see the CPU is used for about 20%. When these pictures were captured the computer was using hellanzb to unrar a long list of rar-files.
When you look at my signature you see the computer is not bad at all, just disk-access is slow. I can transfer files with a maximum speed of 30MB/s. Is that normal or is it very slow? I don't know the numbers. I have 2 SATA disks.
O.S. is Mint 9-Isadora, based on Ubuntu 10.04 and I use the 64-bits version.

Ubuntu Networking :: Ftp Verus Samba / Small Mediaserver

May 31, 2010

-I've got xubuntu 10.04 installed on an old laptop (Toshiba Tecra A4).

-On a little NAS i've got my video-files.

-Using wifi i can go to the smb-share on the NAS to open a video-file on my laptop. (kinda slow/laggy)

-I can also use the ftp-server build into the NAS and mount that on /media/ftp (using curlftpFS on the laptop)

According to what i have read about ftp/smb, FTP is faster! (haven't tested yet)The NAS has got a mt-daapd and twonky but i don't think i can find those in VLC or TOTEM... (? wonder if that would make things faster)

OpenSUSE Network :: Direct NAS Reading And Writing?

Feb 9, 2010

I've been able to get access to our Netgear NAS, I can browse it, copy files etc. just fine. But I don't have "direct access" in as far as, Open Office won't open any files residing on the NAS, neither can I save directly to the NAS form a program and when I get a "Browse for File" form field on a website (eg attachments in GMail etc.), I can't browse to the NAS either. My XP box does do all of this, either through my mapped network drive or even through browsing the network. How can I make openSuse 11.2 use the NAS with my login credentials as if it was a local disk?

Security :: Reading/writing Encrypted NTFS?

Jul 25, 2010

My main workstation incorporates a mixture of ext3, ext4, and NTFS partitions scattered across a number of hard drives. Several of the ext4 partitions are encrypted, and I intend to encrypt the rest of the Linux partitions in the near future.I run VMware workstation, with several Windows OS guests, including Win2K, WinXP and Win7. My Win7 VM is installed on a virtual hard disk, and that virtual hard disk is encrypted using VMware facilities.So this leaves me with a bunch of NTFS partitions that are not encrypted. These are physical partitions on a couple of different hard drives. The reason I have them is ancient and historical, and as I have upgraded my system over time I have maintained the architecture due to the extreme difficulty of rearranging Windows systems.I still need to maintain Win2K and WinXP support, and rearranging those virtual machines would represent a hideous nightmare for me; I really want to maintain the same hard drive partition architecture.But I want to encrypt the NTFS partitions, in a fashion that can be handled by any of the Windows operating systems, AND can be accessed for read and write from Linux.Is this possible? If not using Windows facilities (I don't think ntfs-3g handles encryption, and there are known backdoors in the Windows facilities anyway), is there any third party solution that would work? Would True Crypt do the job in a fashion that would permit access from all the various operating systems, as required? I do generally mount the NTFS partitions in whichever Windows VM is appropriate, then share them out via SMB, but there are circumstances (like when a VM is not running) where I will directly hit them from Linux. So, it is possible for me to contemplate a solution that only works from Windows, but this would cost me the ability to repair/modify those filesystems directly from Linux, which under certain circumstances (a malfunction of the VM, for instance) could be a problem.

Programming :: Reading/writing Every Frame On Ethernet?

Dec 3, 2010

I would like to write a program that can read every ethernet frame arriving on a specific hardware NIC, without a TCP/IP stack otherwise doing anything on that NIC. Likewise I want to be able to write out to that NIC. So every arriving ethernet frame, of all types, would be readable (probably one at a time to preserve frame boundaries). And every write of exactly that same data would send frames out. The data read and written would be the whole ethernet frame. The kernel would do nothing else with this data, but other NICs would still operate as usual.

What I would be doing is that on 2 separate NICs, copying frames from one to the other, as in bridging. But I would also be doing modifications per what my program needs to do (not at liberty to say what that would be). What facility would I need to be looking at to do this? There is no ethernet device file. Would raw sockets be able to do this? The programming language will be C.

Programming :: Writing And Reading Driver Value In Ioctl?

Jan 18, 2011

I just want to read and write some values (integer) to my driver. I used put/get user but always getting errors.

driver

Quote:

int Wert;
static int device_ioctl(struct inode *inode, struct file *file, unsigned int cmd, unsinged long arg)
int ret;

[code]...

Quote:

int WERT
ret=ioctl(fd, SETIT, WERT)
ret=ioctl(fd, GETIT, WERT)

if i say in C++ WERT is 5 the value arg of the driver becomes 5 but not WERT the returnvalue of get and put user is -1 so it failed.

General :: After Writing Successfully A NAND Block Is This Reliable Ar Reading As A NOR Sector?

OpenSUSE Install :: Mount A Live Compressed File System For Reading & Writing From A LiveCD/DVD Image?

Jul 9, 2011

On a Linux CD/DVD, there are compressed filesystem images for the live version for KDE or Gnome for example, but they have no extension, but they are clearly an image file ( compressed filesystem images for the live version before installation ) !!

I was wondering, How do I mount these compressed filesystem images, after I copy the ISO content of the CD/DVD on my system .... I want to edit some files or packages and make some changes, like if I want to customize a live version of gnome for example ! ... ( I know you might be tempted to tell me to use KIWI etc to customize etc ..... ) ... but I want to be able to mount the compressed file system image, then edit it for reading and writing while it is in a subdirectory on its own ... i want to open it ! ... is there a way to do this ??? ... these type of files have no extension ...

i can open this compressed filesystem image then to edit for read & write ... before I roll it back again ..... If and when I succeed .... what should I watch out for ? ... will the same compressed file image but slightly modified work again ?

PS. that same question could be kind of translated or be extended like : how do I use unionfs/squashfs programs on the command line to mount these image files with no extension for read & write mode ???

OpenSUSE Network :: Writing To Samba Share Causes Crashes After A Few 100 MB?

Jul 22, 2010

If this is the right forum i don't know, but I'm having a problem which crashes my home server when writing to Samba. Googling and a quick search in this forum didn't help me any further. Is there anyone with a clue what to do?When I write several hundreds MB to my Samba share from a Windows machine the machine crashes (both with Win XP and Win 7). The problem is reproducible, although the precise moment (about 1 minute) or amount transfered data varies (about 300 to 800 MB). Small writes go well.Reading about 5 GB from Samba to Windows went without a hitch.

Red Hat / Fedora :: SELinux Is Preventing The Samba Daemon From Reading Users' Home Directories

Sep 1, 2010

My Fedora box is giving me an SELinux security error:

Code: Summary:

SELinux is preventing the samba daemon from reading users' home directories.

Detailed Description:

SELinux has denied the samba daemon access to users' home directories. Someone
is attempting to access your home directories via your samba daemon. If you only
setup samba to share non-home directories, this probably signals an intrusion
attempt. For more information on SELinux integration with samba, look at the
samba_selinux man page. (man samba_selinux)

Allowing Access: If you want samba to share home directories you need to turn on the
samba_enable_home_dirs boolean: "setsebool -P samba_enable_home_dirs=1"

Fix Command:

setsebool -P samba_enable_home_dirs=1

Additional Information:

Source Context system_u:system_r:smbd_t:s0
Target Context unconfined_u:object_r:user_home_dir_t:s0
Target Objects /home/micah [ dir ]
Source smbd

Ubuntu Networking :: Samba Crashes 11.04 When Transferring Files <1gb?

Aug 9, 2011

I've got a quadcore PC, 2gb ram pc running ubuntu 11.04 with samba set up on a shared folder - the plan is to share files and media between myself and my housemates. However, I do not have the router attached by ethernet, I am connecting to the router (in another room) by a d-link wireless dongle.

I can access the share without real issue from my windows laptop and other computers in the house share I'm part of, and I can happily transfer a text file here and there, but it seems to be anything over 20mb will not go. All the files I am trying to transfer are >1gb and it's driving me mad.

After some decent transfer rates of around 1mb per second it just freezes up. The screen attached to the actual server goes blank and the host becomes unreachable by ping.I'll be happy to provide any command results or anything to get this working. any assistance would be welcome!

Ubuntu Networking :: Deleting Files Off A Samba Share From A Windows Box?

May 17, 2011

I'm trying to make my music directory, located on my Ubuntu box, available to all the windows clients (Windows 7, to be specific) located around the apartment. It seems to work fine, I can see and read from the shares from my windows box, but deleting files doesn't work, I just get a permission denied.I've tried being as lenient as I can in the smb.conf, as well as setting 777 on the affected files, nothing changes. I've read, from my various googling, that the octal file permissions aren't as important as the samba permissions. Okay fine, but how do I tell samba to ignore permissions and let everyone delete files? I've read that samba works with samba users, but again, I don't care about users, I just want a global share that anyone can connect to and read (and delete) files.

Here's my smb.conf file: http:[url]...As you can see, I've played around a bit with options, but I just can't seem to get anything to work.
