OpenSUSE Network :: 11.4 Slow CIFS Reading
Jun 6, 2011
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

I used command as followings. nothing special. mount -t cifs //192.168.55.53/windows$/Home /mnt/ -o user=username%password It works well after mounted. But mounting itself takes 1-2 minutes terribly. After mounted successfully, file transfer speed looks to be normal.

I'm trying to setup a samba server to share data among clients via cifs. As a test, I mounted the samba share on the same machine and tried to access the contents of the directory. The mount command was:mount -t cifs -o username=sthomaso,workgroup=WORKGROUP //server/scratch /mnt/server/scratch..which worked fine after entering the password. Although I can "cd /mnt/server/scratch", when I try to list the contents of the directory with "ls", I get error "ls: reading directory .: Permission denied".

Q: How can I allow my users to mount a cifs share without an entry in fstab in OpenSuse 11.4?
I have an answer myself. Until OpenSuse 11.2 I could mount my samba shares by making mount.cifs and umount.cifs setuid root. Today I installed OpenSuse 11.4. Unfortunately mount.cifs isn't anymore allowed to be setuid due to security concerns. Security is not an issue in my case, so I copied the mount.cifs and umount.cifs from 11.2 to make it work again:
1. Download cifs-mount-3.4.2-1.1.3.1.x86_64.rpm from this repository (I use 64 bit):
"http://download.opensuse.org/distribution/11.2/repo/oss/suse/x86_64/"
2. Extract the files mount.cifs and umount.cifs from the rpm and copy them to /sbin
3. Make them setuid root:
Code:
linux-y5qw:~ # chmod u+s /sbin/mount.cifs
linux-y5qw:~ # chmod u+s /sbin/umount.cifs
4. Mount your cifs shares as a normal user:
Code:
martin@linux-y5qw:~> /sbin/mount.cifs //192.168.2.2/data /home/martin/data/ -ousername=martin

Question 1.I have strange problem in OpenSUSE 11.2I have /etc/fstab entry:
//server/projects /server/projects cifscredentials=/root/.credentials,dir_mode=0777,file_mode=0777,_netdev 0 0

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:

I just made a fresh install of OpenSUSE 11.4-Tumbleweed and have the latest updates. However fstab lines I've used in the past are not working.
Here's an example of two:
//IPADDRESS/share /home/user/mount cifs credentials=/home/user/.scripts/.creds,_netdev,uid=client_user,gid=users 0 0
//IPADDRESS/share /home/user/mount cifs guest,_netdev,uid=client_user,gid=users
I can execute a command
Code:
sudo mount /home/user/mount and it works, but I'm wanting all my fstab lines to automount at boot as on other machines.

I have a SMB share being mounted during boot using a /etc/fstab entry.All that seems to work fine, but on shutdown or reboot I found that the system hangs for a variable period trying to unmount the share. It appears from the log that the unmount is happening after the network connections are closed.Is there someway around this, or is there some other way I should be mounting the share so that it is closes successfully at restart or shutdown?

We recently moved to a new home and I am trying to get my home file/print server set up again. Thanks to swerdna's excellent website, I got my server box (just upgraded from 11.0 to 11.2) running Samba and serving my shares over the network, and my "client" machines can access them without a problem.However, I'm not having much luck setting up CIFS mounts on my Linux desktop. I have my all-purpose user added to the Samba auth list (via smbpasswd), and configured my client as swerdna's howto's specify, and I can access the files just find. However, when I try to mount the shares with this command:
Code:
mount -t cifs -o username=klein,password=klein //192.168.1.70/sharedmedia /home/zak/SharedMedia/
I get the following error:

I need to mount a windows share on my OpenSUSE 11.3. I get it using the mount.cifs command (by itself or using cifstab), but only root can rw file. I try the uid/gid parameters (also using forceuid) and the file_mode/dir_mode parameters, but I get the same behavior: all files and directory with rwxr-xr-x permissions and root/root (user/group). I read the whole section FILE AND DIRECTORY OWNERSHIP AND PERMISSIONS in man mount.cifs but nothing works.

Q: How do I mount a CIFS share so that my user stevej has all rights to it?
Summary: I can mount the share as root.
mount.cifs //10.x.x.x/Data /home/stevej/Synology/Data/ --verbose -o user=stevej
Using Dolphin in Super-User mode, I can copy files and directories from the share to itself with no errors. Using Dolphin in Normal-user mode. I get the failure "Could not change permissions for...". The file is copied, but its owner,timestamp and permissions are wrong. If a subdirectory is involved, the copy aborts.
Using Windows XP I can copy files and directories from the share to itself with no errors.
Testing: If I mount with uid and gid, then my normal user can not access the share.
mount.cifs //10.x.x.x/Data /home/stevej/Synology/Data/ --verbose -o user=stevej uid=stevej gid=users
[code]...
Synology DS211 - There are 2 users on it. One of which is stevej and the other is julie. Rights RWX are applied to the users and the group called users. All files have stevej as the owner and users as the group with RWX Opensuse 11.4 - There are 2 pc's. One is run as stevej. The other pc runs as julie Windows 2000 - Runs as stevej and maps to the share as stevej.
Works as expected Windows XP - Runs as julie and maps the the share as julie. Works as expected Ultimately, I want the shares to automount at boot, or login and give the user full access. I have been to Swerdna's page and done as much as I can, but still no luck.

I'd like to have a CIFS drive mountable for various users. Each user uses different credentials and I want the drives to be automounted without using sudo-rights. I imagine the best thing to do would be to have the fstab entry point to multiple credentials files. Is there a way of doing that?

Am in the process of upgrading from an ancient OpenSuSE release (7.2) to 11.2. One thing I have been unable to do that worked fine under 7.2 is remotely mounting a compact flash drive from an XP machine. Worked fine for many moons on 7.2:
# mount -t cifs -o rw //xpbox/'cf (H)' /cf0
I get:
mount error(12): Cannot allocate memory
Other cifs mounts of hard disks work fine.
I found a posting that says this means the memory allocation error is from the XP side. It says to fiddle with the XP registry, specifically IRPStackSize. I was not confident this fix would work since there should not be anything significantly more consuming with 11.2 compared to 7.2, and indeed, I got the same error after changing the parameter to 18 and rebooting the XP machine. Any ideas? I have some suspicion that the space and parenthesis in the share name might be fouling up someone. XP forces the share name to this for some reason.

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?

I have a Hitachi SimpleNET adapter (entry-level NAS device) on a Seagate FreeAgent 1TB external HDD (formatted ext3). The NAS device is connected over 100MB/s ethernet to a Netgear Wireless G router. All other devices connect using Wireless G. The NAS runs embedded Linux on an ARM processor and it runs vsftpd and Samba for file transfers.
If I transfer a large file using an FTP client the transfer maxes out at around 2.5MB/s. For my purposes that's good enough, especially considering the Wireless G bottleneck. If I transfer a file from a Windows 7 client (using samba) I get around 2.2MB/s. I know the CIFS protocol has more overhead than FTP and the difference in speed isn't that noticeable.Any combination of Ubuntu and Samba results in me getting less than 1MB/s. I've tried mounting it through Nautilus (GVFS) and /etc/fstab. FTP from this same Ubuntu client gets around 2.5MB/s.
I don't have root access on the SimpleNET to change the smb.conf. I've made a few adjustments to the mount options with no success. how to either speed up 10.04 as a Samba client or mount a folder on an FTP server locally? I've tried both curlftpfs and FUSEFTP. With curlftpfs any write operation results in an I/O error and it crashes intermittently. With FUSEFTP I never got that far and couldn't even browse the folder.

The shares get mounted correctly and you can navigate through the directories and open files.The only problem is that it randomly starts going really slow taking 30 seconds or longer to open a directory that has 2 or 3 files in it.I have tried quite a few things to try and fix this without any luck. Its getting to the point where I am having to consider recommending that we use windows instead, which I would rather not do as I think its good for students to experience different operating systems during school.

I've mounted a kind of proxy to map some cifs folders, 150 aprox. It umounts and mounts everything each hour, to check on changes on a configfile managed by a secretary, she just edits a file with names and I prepared a cron to notice the new mountpoints. It's a debian, no desktop , no nothing else. Just mount.cifs and apache2 to let the master webpage access to some files on each user samba home. The server has 4 cores and 2Gb of RAM. It's brand new, but it goes very slow.
[Code]....
Does anyone have an idea why is that working so slow? The apache is working well, it's the shell which is working extremelly slow.

Recently changed my motherboard. The new board has the 790FX/SB750 chipset, and the old board used the 770/SB600 chipset. Prior to the change, I had never had any problems reading/writing CDs or DVDs. I now find that reading a data CD is very slow, it can take up to 30 secs before the icon appears on the desktop and a filer window appears. In my tests thus far, only data CDs written on Linux can always be read, albeit slowly. Data CDs written on Windows are variable. Some are never seen by the system, others may or may not be opened. That is I might be able to read it during one test, and next time I try I can't.
When a CD is not 'seen', there is an initial flurry of activity by the drive, but the drive icon (in "Computer' window) doesn't think a disc is in the drive. I can boot OK off a DVD, and data DVDs wrtten on Linux are opened and read quite fast. I am running Fedora 12 x86_64 with the latest Fedora kernel package (2.6.32.9-70), and the Motherboard bios is the latest available. The CD/DVD drive is a SATA Pioneer DVR-215. I have checked the bios settings, and have tried setting 'storage configuration' to IDE and to AHCI, each giving the same result.
I tried switching the SATA data cable from SATA-3 to SATA-2 and was able to open and read a Windows data CD that had previously not been seen, but subsequent attempts have failed to open and read that CD. I suspect the problem may have something to do with hardware drivers, but I really am guessing about this and have not been able to find any useful information on this.

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.

Does anyone know how to revert network speeds to those attained with openSUSE11.2-64? On openSUSE11.2-64 the reported network download speed was,
max : 420 kB/s
ave : ~ 200 kB/s
After upgrade to openSUSE 11.3-64 the figures dropped to about 25% of the previous values. After upgrade to KDE 4.5 and plasmoid-networkmanagement the initial values did not change but the average value dropped after about 30 seconds to ~ 15 kB/s. Approach so far:
1. The motherboard's (A780GM-LE) build in LAN (Realtek RLT8111DL) was originally detected by openSUSE 11.3 as the Realtek RLT8169 and kernel module r8169 installed. This was replaced by the latest module r8168-8.019.00 from Realtek.
2. After kernel update to Linux 2.6.34.4-0.1-desktop x86_64 the plasmoid-networkmanagement was replace by NetworkManager-kde4. This improved flow with,
max : 140 kB/s
ave : ~ 80 kB/s

I have a Ralink rt2870 chip. Since it did not work with 11.2 out of the box (should it not be in the kernel?), I had to install this driver from the software search area on opensuse.org:
After installing it, it works, but only at reduced speed, (I think), because when keeping the mouse over the list item (of that connection) in Network Manager, a window pops up saying I only have 54Mbit/s.
It says:
Type: WiFI
Interface: ra
Hardware adress: 00:15: .....
Driver: usb
Status: connected
Bit rate: 54 Mbit/s

I have recently moved countries and have finally got my internet connected today after a lengthy wait. I have a pretty fast connection - it's a fibre connection at approx 100Mbps Between my onu (modem) & computer (Lenovo SL510) I have a cisco wrt120N wireless router. I'm using Opensuse 11.3 (also dual boot with Win7)
My problem is . . . When I enter url in firefox (4) I get the message "looking up www. . ." for approx 5 to 15 seconds before anything starts to load. I also have the same behaviour in konqueror, firefox and yast software manager.
If I use Google Chrome the pages load instantly. Even never before visited pages.
A typical webpage such as Stuff.co.nz - Latest New Zealand News & World News, Sports News & NZ Weather Forecasts takes approx 20 to thirty secs to load in firefox and 3 seconds in Chrome. I can see the same behaviour always whether Chrome used first or firefox used first - so cache does not appear to be the issue.
If I boot into Win7 - websites load instantly there also.
I have updated to the latest wireless drivers for my system - but the behaviour is also evident if I attach a lan cable.
Here is a little info
Code:
/sbin/ifconfig
eth0 Link encap:Ethernet HWaddr 60:EB:69:AE:C6:28
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0

I've recently installed openSUSE 11.4 (64 bit) on my system and am experiencing severe performance issues with websites using https (any site using https). Page loads over https take anywhere between 30 seconds to 2 minutes. It's the same issue posted here Secure sites load slow or not at all -- there was no confirmed solution.
- My router/hardware configuration has not changed in a long time and I've run Ubuntu, Arch Linux, and Windows XP on the same machine within the last year and have not had any issues.
- I also have a laptop running Arch Linux (kernel 2.6.38) and this problem does not occur using Firefox 4 or Chrome. To add to the madness this problem occurs while running Firefox 4 inside a Windows 7 guest via virtual box, but NOT while running IE 8 inside the same guest.
- This issue occurs using Firefox 4, Chromium, Opera, Konqueror, and Arora.
- I've disabled ipv6 in Firefox via about:config.
- I've disabled ipv6 in yast and have attempted to use both the "ifup" and "networkmanager" options.
- I am not using a proxy server.
- I've attempted the fix posted in the Ubuntu forums for a similar problem [ubuntu] [SOLVED] Banking Site is very slow.

I have mounted a windows network share using the gnome desktop environment, using Places -> Connect To server.The network share is OK, and I have the icon on my desktop and can see all the files.I want to be able to use this network as well in the console, so I need the mount point.What is the location on the filesystem were this networkdrive gets mounted? I find nothing in /mnt and nothing in /media also using mount to look at the registered mounts, there is no entry for the networkdrive.Nevertheless, I have this networkdrive now open in my desktop, and have an option to unmount it.I know that using the mount.cifs command you can specify the mounting point.

I'm running 11.2 on a Dell Latitude D630. Everything has been great other than issues with Suspend and hibernate not working correctly. However after about a month of use browsing the web has really slowed down bad. It doesn't seem to matter if it's in Firefox or Chrome either. I am using a wireless connection that is getting the signal at 85-95%. Even though I still tried using a direct cat-5 connection to the router and it was still slow as well. I have the fastest broadband connection my cable offers and my windows boxes on the same network are still flying.

Recently I purchased a new laptop and installed openSUSE 11.3 x64 Gnome. I was running openSUSE 11.2 x86 Gnome on my previous laptop. Most things are working well, although still tweaking things here and there.
The biggest issue at the moment is starting the network. When I boot the system it loads into desktop (gnome) no problem, but then takes between 3 - 5 minutes to come up asking for Default Keyring Password before it will launch network manager. Everything else has loaded and it running fine except the network.
The first time I launched the system (after install) it worked perfectly, however soon as a set the password for the Default Key this started happening. The time delay before it launches does vary each time but always around 3 minute mark.

I just installed openSuse11.4 KDE in dual boot with Win7. I have observed that Firefox can open websites but in contrast to this, whenever I try to install rekonq web browser (thats because I find Firefox the slowest browser presently available on earth), Yast says about 593 MB of data to be downloaded and installed. It starts with 3.2 KB/s (or even lesser) speed and further decreases to about 1.3KB/s speed and then ... just stops there (waited for 2-3 hours for downloading just 4-5 MB of data).
