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?

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 ???

I've used ext2ifs drivers to mount my ext3 partition in winxp, but I don't have write acces, it's mounted in a read-only mode, and i didn't check the rad-only box during the installation of the drivers. [URL] It's a straithfoward proces so I dont understand what I did wrong. I'm using fresh xp install with (more or less) all the updates and ubuntu 10.04 Also the partition is mounted at /home, so I dont know if that makes any difference.

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.

I am about to write a program to listen and read data from /dev/ttyS0 and write the data to /dev/ttyS1 after processing. Also, the same time I need to listen to /dev/ttyS1 and write to /dev/ttyS0 if any data arrived at /dev/ttyS1.

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.

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.

There is the Archive::Zip I think I can use with Perl 5.10 but I don't know how. I don't want to read or write any files, just zip something in memory, with best compression, like
$text = "this is a test";
$zippedtext = &Zip($text);
sub Zip {

I guess it's only a few lines.

Here the description of the issue I am having.I am writing a bash test script which reads lines from a file, builds ISO messages, sends them to a server, reads the response with response code and reports the result of the test to a file or on the screen.The message that I need to send is 94 characters long.Here's the portion of a code that I initially wrote:
~ Open socket.

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.

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.

Am interested in using MT29F2G08AABWP NAND Flash memory for a new embedded design and I couldn�t find a clear specification regarding how reliable is the NAND flash vs. NOR for reading operation.If I program successfully a NAND block, read back and verify successfully the information and never erase or program that particular block again, can I assume that block will remain a good block and the information written there is safe for READING, roughly as safe as a NOR sector?

I mount the share on my Windows server with following command:
Code:
mount -t cifs -o username=Administrator,password='mypassword',rw,dir_mode=0777,file_mode=0777,nobrl,uid=1000,gid=100 //10.8.0.1/users /mnt/
In my 11.3 computer it works well. I opening, copying files like I do in local filesystem. At the same time it's not working well on my 11.4 computer: the share mounts without errors, I see all files, can copy them from server to local computer. But when I'm trying to make copies to server, sometimes I receive messages like "Error writing file ...". Not always, but in the most part of my attempts. find the part of my /var/log/messages file:
Code:

1. 11.4 x64.
2. Solaris SMB server.
3. Gigabit LAN
4. mounted shares from that server (fstab entries)
write speed: 80-90-100 MB/s read speed extremely slow: 3-4-5 MB/s (really funny - our administrator shoked, but i'm not fun, i need fast lan for work)But when i reboot to windows 7 - i have 60-70-80 MB/s in both directions. Read and Write - nice.What happened? kernel updated and all last updates is applied (exclude kopete-because i use old kopete with animated tray icon).I have to tried many tunes like: "noatime" "directio" and also in /etc/modprobe.d - put conf file with: options cifs CIFSMaxBufSize=130048

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.
Hardware:
- Foxconn r10-s3 (includes Atom N330) with 2 GB RAM

I am currently running OpenSuse 11.2 still having problems with sound, CD-burning and the like being a total newbie. But I am also a very curious person.
So my questions are: Is it
a) advisable to upgrade to the latest version when there are still problems to solve in the old version and after quite some work the most important functions are up and running
b) is it possible technically speaking to upgrade directly from 11.2 to 11.4 without risking too much.

I try to understand the way the network-admin tool retrieve and set information about the network connections, and after reviewing thee code, I still dont undertsnad how it does it. I thought that it should use maybe linux commands such as iwconfig or ifconfig or by using ioctl for get/set the parameters of the wireless, but I did not find such things in the code. It also does not use AT commands for modem devices parameters.
I see that it uses liboobs files, but after veiwing the code, I still don't understand how it works.
These question comes since I work on application which connects to wireless devices (possibly several wifi and modems devices can be connected ), and I try to think how to set/get the network parameters, I thought that a good start will be to look at how network-admin works.

I have a server set up with Samba. On the desktop side I use KDE. I can clearly track intensive smbd activity, being the first on the iotop results page. Another thing is that after reading from the server's HDD, it seems to write on the desktop's SSD. It does this intermittently.I really want to know how can I stop this. It's very annoying and I bet I don't need it since, using previous versions of Debian, I could go well without this activity.

I have just formated and did a fresh install to start all over. I installed Ubuntu 9.1 and everything went fine but the network. The computer serve as a NAS and MediaPlayer. When getting a file from the server, I get a speed of 40-60mb/sec, which are good for a Gigabit network. When I try to put a file in, the speed can't pass more than 1mb/sec and often stop.
Here's the network info:
Code:
vric@XBMC:~$ ifconfig
eth0 Link encap:Ethernet HWaddr 00:24:8c:a1:eb:55
inet addr:192.168.1.5 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::224:8cff:fea1:eb55/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
[code]...
Edit: Looks like it's a Gigabit Problem. I connected the Ubuntu box to my Linksys router which is 10/100 and everything is MUCH faster.
