KDE Konqueror NFS Problem

Hello,
i have NFS up and running,
if i mount it per hand all is functionally,
i can copy files between all shares only
in konqueror 3.2 or 3.3 i can only read files from
the nfs shares if i going to write a file i get
an rpc failure ??
i only found these in the kernel log:
kernel: RPC: bad TCP reclen 0x00000f9c (non-terminal)
in konquereo it works also if i mount the nfs share by hand or fstab.
can anyone help me
regards

Strange networking/NFS problem

Hello,
Occasionaly I'm having NFS slowdowns, then I see this information in dmesg on the client:
nfs: server galaxy2 not responding, still trying
nfs: server galaxy2 not responding, still trying
NETDEV WATCHDOG: eth0: transmit timed out
nfs: server galaxy2 OK

NETDEV WATCHDOG: eth0: transmit timed out

nfs: server galaxy2 not responding, still trying

But on the server, I see nothing in dmesg. But, I do see this:
eth0 Link encap:Ethernet HWaddr 00:0E:0C:72:83:51
inet addr:192.168.1.1 Bcast:192.168.1.255 Mask:255.255.0.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:185954 errors:774 dropped:774 overruns:774 frame:0
(notice the high errors/dropped/overruns)
The LAN is a GigaBit lan, on the server:
00:09.0 Ethernet controller: Intel Corp.|82547EI Gigabit Ethernet Controller (e1000)
on the client:
00:0a.0 Bridge: nVidia Corp.|Ethernet controller (forcedeth)
The entry in rc.conf for the network looks like this:
client:
eth0="eth0 192.168.1.102 netmask 255.255.0.0 broadcast 192.168.1.255"
server:
eth0="eth0 192.168.1.1 netmask 255.255.0.0 broadcast 192.168.1.255"
Is this an NFS problem or a networking problem??
Thanks.

netmask should be 255.255.255.0 according to your broadcast
y should also have a look at network-components before your server also an easy one would be to change the cable
once our database was instable due to a cable-problem (was fine for 6 months before)

NFS Problems - Disconnects in iTunes

I think I have this problem posted by scree and I want to look at the posted solution buy the solution link is dead, the original thread is archived and I don't know how to send a message to scree.
Anyone know the solution described at http://blog.lemon23.com/news/nfs-unter-leopard/nfs-unter-leopard.html ?

i expirienced the same problems (and even more) with my ubuntu-NFS-server and my mac (as a client) which worked very good in 10.4. no problems on the terminal, but lots of disconnects and interrupted server connections when using itunes or iphoto via NFS...

solution posted here: http://blog.lemon23.com/news/nfs-unter-leopard/nfs-unter-leopard.html
no more interrupts, everything is working fine.

I found your post while digging for answers to the same problem myself. Essentially, my NFS mount of my iTunes library (Centos 5.1 server, gigabit ethernet) was working fine until I hooked up my 40GB iPod (no problem with the smaller ones). I would get the same NFS disconnects that I had with iPhoto, which had made it impossible to use the NFS mount for it.
Well, the good news is that I found a copy of the post you had a link for in the internet archive: http://web.archive.org/web/20080212115443/http://blog.lemon23.com/news/nfs-unter -leopard/nfs-unter-leopard.html . Essentially, the author suggests 3 things:
1) use the same uid and gid for users on your Mac and NFS server
2) disable the generation of the hidden OS X files (e.g. .DSStore) by using 'defaults write com.apple.desktopservices DSDontWriteNetworkStores true'
3) change the NFS mount options to 'locallocks rsize=32768 wsize=32768 intr noatime'
I knew that 1) was important and already had that in place. 2) I don't think should make a difference, it didn't do the trick for the OP either. 3) essentially tells NFS to use local locks, to set the local read and write size to 32k bytes (could have used rwsize=32768 instead) and to allow for any NFS operations to be interrupted. I am not sure that the noatime option is supported in OS X, but on linux machines it tells the client to not constantly update atime on NFS files.
Digging finally into my system.log, I find lots of errors from lockd (lockd not responding), so my hunch is that the most important setting was the 'locallocks' option for mount_nfs (via the Directory Utility app). In any case, my disconnects (doing all 3 of the above) have vanished, even for iPhoto although I have only tested that very briefly.
Hope this helps!

KDE: Konqueror with man pages - also Firefox/Shiretoko styles

Greetings!
I've only recently started using Arch. Two weeks ago I installed, and so far all is going well, and I have to say that I'm very impressed with both the quality of this distribution and the thoroughness of the Wiki.
I've encountered two minor annoyances that I simply can't figure out, and can't find in the Wiki...
1) I like using Konqueror for man pages when I have a GUI because they are somewhat easier to read. Anyway, Konqueror displays them, but it's as if I haven't gotten the character set correct or something. What happens is that some of the formatting code comes through as text. For example, I'm looking at the smb.conf man page in another window right now, and the first several lines of text look like the following:
SMB.CONF
Section: File Formats and Conventions (5)
." make the size of the head bigger
\ ." make the size of the head bigger \
2) I'm using Firefox installed straight from the repository. I next installed and used lxappearance appearance to change the style to the QTCurve style as suggested in the KDE Wiki page. This works great, and Firefox looks more like a native KDE application right up until I log off. When I log in, Firefox is back to looking like a foreign application again, and I have to run lxappearance again. It only takes a few seconds, so it's an annoyance at worst, but it is somewhat annoying. I have not tried switch2 or gtk-chtheme, perhaps I should?
I can't believe I'm the first one to have these problems - but I've been searching and reading the Wiki as well as the general internet and haven't lucked onto anything for either problem. I would really appreciate a link or hint pointing me in the proper direction for either or both of these problems.
Thanks for any tips or links!
Chris

Er... my 's's have magically returned? But I have no idea why. I didn't even restart Firefox. (I'd already tried that and it made no difference.)
Would really like to know why...
EDIT: I still don't have 'm's etc. in code listings, though.

Kde, Konqueror & audiocd:/

I'm having problems with audiocd:/ protocol in Kde. If I try to open audio cd with konqueror I get
unknown protocol: audiocd
Still, I'm able to play the cd with amarok and rip the cd with k3b.
What's wrong with the audiocd protocol?

Reinstalling kdemultimedia seems to fix things.

Important KDE network apps problem

I have a strange problem : All internet related programs are slow on KDE, they have all a 5-second latency before doing anything. When i use kmail or konqueror for example, i have to wait about 5 second before anything to react. The problem stops when I install a proxy on my computer, squid in that case. It partially resolves the problem, but it can't be used for knode, kmail or any non-web internet programs.
I don't know how to solve that, i hope you'll help me.
Thank in advance,
V.

Fixed.
I just installed bind and set "nameserver 127.0.0.1" to resolv.conf.
It seems that it was a named problem. Hard to believe but it works now..

KDE 4.10. problems

Hello,
Yesterday I upgrade KDE from 4.9.5 to 4.10. All went perfect but now, some apps like Kmess and Gajim doesn' t use the KDE notifications and use their own notifications ( a green window in the case of gajim and in kmess a pop up on the middle of the top panel, they look terrible ) Anyone nows how to restore the kde notifications ?
P.D: Antoher problem I have is that the device notificator now always says that I have a mounted 0b floppy disk.

George wrote:Make sure you've got the notifications widget enabled in the system tray settings (right click on the sys tray).
Thank you, now I have notifications again. But the problem with the device manager cointinues. It shows a Floppy disk with 0 bytes size, I can' t access the data ( because this device doesn' t exist ) and I can' t umount, and is always on the try. I checked fstab file and there is nothing strange. It could be a bug of udisks ? This is the output of the command udisks --dump.
udisks --dump

Workaround for NFS problem

I am experiencing the following problem with the NFS client on Mac OS X Snow Leopard. I NFS mount a NFS share (say at /mnt/nfs). I run a program which reads from, and writes to, some files in some directory /mnt/nfs/adir. In another Terminal window I run "cd /mnt/nfs/adir ; ls -l". The directory listing is very slow. However - and this is the problem - if I then interrupt the directory listing (Ctrl-C), the other process (i.e. the program in the other window) that was accessing /mnt/nfs/adir aborts with the message "aprog: STDOUT: Interrupted system call".
Can anyone else reproduce this behaviour?
Is there a workaround?

+Is there a workaround?+
Yes. Don't start the second process until the first one is finished.

Kde 3 Emulator Problem

I use Wireless Development kit on SuSE 8.0 with Kde 3 and the Emulator-Phone Window size is about 50 x 20 pixel...(and i can't change the size) anybody knows what to do?

Problem solved... there seems to be a bug in the jdk1.3.x that Frames don't get the right size ... in Jdk1.4.0 all works fine.. ;-)

NFS-Problem

Hi,
I have some problems with an nfs-mount to a netapp-filer.
The mountoptions are as follows:
soft,noac,rsize=65536,wsize=65536,vers=3,proto=udp
In /var/adm/messages I get messages like this:
Dec 3 08:04:11 uaizk15 nfs: [ID 664466 kern.notice] NFS read failed for server filer406: error 5 (RPC: Timed out)
Dec 2 13:27:15 uaizk15 nfs: [ID 664466 kern.notice] NFS fsstat failed for server filer406: error 16 (RPC: Failed (unspecified error))
After changing the mountoptions to rw,bg,hard,nointr,rsize=32768,wsize=32768,vers=3,nosuid,proto=tcp I lost connection:
Dec 2 13:17:32 uaizk15 nfs: [ID 333984 kern.notice] NFS server filer406 not responding still trying
ping is o.k.
Have somebody an idea?

I'm sorry that I wasn't clear enough. The head unit (regular Xserve) has 3 internal drives, with one containing the OS. It is one of the other two drives that unmounts. The other 29 are cluster units and only have one internal drive. When whatever it is happens, both of the NFS shared drives (one internal and the RAID) unmount.
The RAID is directly attached to the host. All connections have been checked. No errors appear in the RAID log or the system log.
Originally we had the home directories and data collection going to the RAID. It would exhibit the same issues (but with only the RAID dropping offline). We then switched the data collection to the internal drive, while the home folders remained on the RAID (so very little data xfer going to the RAID now). Now BOTH drives get kicked offline when whatever it is happens.
We are using NFS vice AFP because of an apparent permission issue with Gridware and AFP. Jobs seem to run only as the user that submits, which then locks out all subsequent jobs from being run. We have not tried ignoring all permissions on the drive, as that may cause other issues.
All drives are, I believe HFS+ and journaled. The RAID is 1 terabyte. The other drive is 80GB. When they get kicked off and are brought back on (always requiring a reboot of the head unit), they seem to go through a directory compare and rebuild. Happens every time. The non-NFS shared drives do not go through this process. There does not appear to be any data loss or corruption.
The simulation creates lots (thousands) of small files (both for submission and results). Not many directories.
So, to summarize, when this happens, all NFS-shared drives drop offline and have to go through a rebuild (even if they are not RAID) once they come back on (which can take nearly 2 hours with the RAID).
Hope this clarifies a bit. We are certainly stumped.

KDE, Konqueror and Java... HELP!!!

i'm running RedHat 8.0 w/ KDE and i can't seem to get applets running at all, i know that my JVM works fine since i use it to compile and run my apps but i can't seem to get applets running at all! under settings have i "enabled java globally" and have tried to set the "path to ajva executable" but i'm not sure what to point it to... any help is useful

I'm not entirely sure about Konqueror, but this is what I did to get it to work on Mozilla and Galeon. I be that Konqueror won't be too much different < http://members.shaw.ca/trollking >.

NFS problem between RedHat Client and Solaris Server

Hi all, we are experiencing a problem between a RedHat client and a Solaris 10 server. For the purposes of this post, I'll call the Redhat client server A and the Solaris 10 server B.
Server B is exporting a filesystem that server A is trying to mount. Server A can successfully mount the exported file system, however, strange things are happening. If I change to the exported mount point on server A and create a file, the file is owned by nobody:nobody, not the user that created the file.
A look at the file on server B shows the file has the correct UID and GID (ie the UID & GID of server A).
The fstab file on server A looks like this:
serverB:/data /data nfs4 rsize=32768,wsize=32768,hard,nointr,rw,bg,actimeo=0,timeo=300,suid 0 0
Does anyone have a explanation for this?
NB: There is a firewall between server A and server B. A firewall rule is in place to allow traffic between the two servers on port 2049

Hi
If I change to the exported mount point on server A and create a file, the file is owned by nobody:nobody, not the user that created the file.On a NFS share, for security reasons, you normally dont have root provileges.
A file createt as root user will be mapped to nobody:nobody.
The behaviour you see is correct.
If you want the file to be createt as root, you have to export the filesystem with -o ro,anon=0
NFSv3 will be blocked by your firewall.

[solved] kde without arts - problem with aplay/knotify

Hi,
I finally got convinced to switch of arts for kde. Amarok runs much better now but I face a problem with knotify/aplay.
With arts not active knotify won't play sounds anymore. knotify is the program responsible for kde's bells and whistles, like playing a sound when you open or close a window etc.
knotify specifies an option for an external player, which I think is the thing to use in case you don't use arts.
I configured that option to use aplay, the sound replay program provided by alsa. However, that has problems. Many kde sounds come with 8khz sample frequency. If I play one of these sounds with aplay their playback frequency is much to low and the sound is heavily distorted. It seems the downmixing does not work.
If I use aplay -Ddmix or -Dduplex I get following error:
Playing raw data 'KDE_Beep.ogg' : Unsigned 8 bit, Rate 8000 Hz, Mono
aplay: set_params:857: Sample format non available
I think that may have something to do with my .asoundrc or maybe there is another program to use for sound playback I don't know about. Also, I could be that knotify IS supposed to play the sounds even without arts running and something else is wrong.
Here is my .asoundrc, any advice is welcome:
# Set default sound card
# Useful so that all settings can be changed to a different card here.
pcm.snd_card {
type hw
card 0
# Allow mixing of multiple output streams to this device
pcm.dmix {
type dmix
ipc_key 1024
slave.pcm "snd_card"
slave {
# This stuff provides some fixes for latency issues.
# buffer_size should be set for your audio chipset.
period_time 0
period_size 1024
buffer_size 16384
bindings {
0 0
1 1
# Allow reading from the default device.
# Also known as record or capture.
pcm.dsnoop {
type dsnoop
ipc_key 2048
slave.pcm "snd_card"
bindings {
0 0
1 1
# This is what we want as our default device
# a fully duplex (read/write) audio device.
pcm.duplex {
type asym
playback.pcm "dmix"
capture.pcm "dsnoop"
# CONVERSION PLUG #
# Setting the default pcm device allows the conversion
# rate to be selected on the fly.
# duplex mode allows any alsa enabled app to read/write
# to the dmix plug (Fixes a problem with wine).
pcm.!default {
type plug
slave.pcm "duplex"
# Apparently this is wrong (breaks mplayer for me opening the device)
#ctl.!default {
# type plug
# slave.pcm "snd_card"
# AOSS #
# OSS dsp0 device
pcm.dsp0 {
type plug
slave.pcm "duplex"
# OSS control for dsp0 (needed?...this might not be useful)
ctl.dsp0 {
type plug
slave.pcm "snd_card"
# OSS control for dsp0 (default old OSS is mixer0)
ctl.mixer0 {
type plug
slave.pcm "snd_card"
Cheers,
Dominik

Ok, I came to a solution.
My .asoundrc was ok. It was aplay that I wasn't aware of it couldn't handle .ogg files, it tried to play it anyway and that's why I got garbled sound output *headdesk*
I installed alsaplayer, after running it once I edited .alsaplayer/config to use the "text" user interface by default. Setting alsaplayer as external player for knotify seems to work.
However, knotify won't let me play sounds in quick succession, so I lose a knotify sound every now and then.

KDE (KMod3) Logout Problem

I am using Kmod3 on an EeePC 901. I have an irritating (but not serious) problem with the KDE logout menu.
If I select "End Current Session" all seems to work OK, then when I try to log in as another user (or root), the background image appears, the Autostart scripts run, but the desktop does not appear (Icons, toolbars, etc). I have to CTRL+ALT+DELETE to force a shutdown, then start again. All other Log Off options work perfectly.
I'd be grateful for any suggestions.

Funny ... I looked for a similar problem in the forum records and did not find any ...
I'll give your idea a try.
Just for the record, I do not think the problem is related to Intel drivers (as suggested in one of the threads) because one if the machines has an nvidia card... the second system does have an Intel video card though.
Thanks again.
R.

Various NFS problems

I'm quite new with Arch and I'm having a lot of problems with NFS.
At home I've a small home server (running Ubuntu Server 12.04) with some NFSv4 shares. On the client (the one running Arch) I mount the shares with the following line in /etc/fstab:
192.168.1.1:/ /mnt/nfs4 nfs4 noauto,x-systemd.automount,x-systemd.device-timeout=20,rsize=8192,wsize=8192 0 0
The shares are correctly mounted at boot and I don't have any problems when I copy files from the server to the client. Performances are really good: with big files I've seen transfer rates up to 80-90MB/s.
Things get messy the other way around, when I copy files from the client to the server. If the files being copied are small it usually works fine, but if the files are big (let's say 1GB+) the copy always hangs after 20-30s. When this happens the entire system becomes laggy and unresponsive. To get an usable system again I must stop the copy (not an easy task with nautilus freezed) and umount the nfs shares or, alternatively, reboot the entire system (the faster method).
Any ideas?
PS: sorry for my terrible english.

Hello,
You need to provide more information in order to find a solution. It can be a network, disk or configuration problem, or maybe something else.
You can try to:
- Detect disk errors using dmesg and copy the file locally on the server share (using a flash drive for example)
- Copy the file using the terminal from the client
- Use other protocols to send the file on the server (FTP, SSH, SAMBA, ...)
- Monitor your network, cpu and memory during the copy process (on the server and the client)
- Use another client or OS to mount the NFS.
- Investigate the logs and send useful information.
The steps above aren't in a relevant order. You can also provide your NFS configuration file, you connection type (wireless, wired, with/without router/switch/hub), the file system of your drives.
Thank you.
