NFS4 problems -
by Bob Goodwin 03 Dec '12

03 Dec '12

I have a problem writing to one nfs4 server from this F-17/64 computer, /etc/fstab is as follows: [bobg@box7 ~]$ cat /etc/fstab # # /etc/fstab # Created by anaconda on Tue Aug 7 08:37:16 2012 # # Accessible filesystems, by reference, are maintained under '/dev/disk' # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info # UUID=4ce86523-2d45-4174-85e9-fd298e4516c8 / ext4 defaults 1 1 UUID=1a9d0937-2247-4cbc-b27d-4775c7453dba /boot ext4 defaults 1 2 UUID=96a666e2-73ac-4f5f-98bc-4a6a9383491f /home ext4 defaults 1 2 UUID=9cb5a7e0-c752-4563-b7f5-663980e090e3 swap swap defaults 0 0 192.168.1.8:/nfs4exports/home/ /mnt/HOME1 nfs4 defaults,rw,user 0 0 192.168.1.8:/nfs4exports/data/ /mnt/DATA1 nfs4 defaults,rw,user 0 0 192.168.1.48:/SRVR1 /mnt/BOX48 nfs4 defaults,rw,user 0 0 Everything I can think of on the server is set "rw" Obviously I have missed something but I can't find it, get "Read-only file system." [root@box7 HOME1]# cp -r /mnt/BOX48/digicam/* /mnt/HOME1/digicam/ cp: cannot create regular file `/mnt/HOME1/digicam/DSCN0001.JPG': Read-only file system cp: cannot create regular file `/mnt/HOME1/digicam/DSCN0002.JPG': Read-only file system cp: cannot create regular file `/mnt/HOME1/digicam/DSCN0003.JPG': Read-only file system cp: cannot create regular file `/mnt/HOME1/digicam/DSCN0004.JPG': Read-only file system cp: cannot create regular file `/mnt/HOME1/digicam/DSCN0005.JPG': Read-only file system [root@box7 HOME1]# chmod 777 * chmod: changing permissions of `bobg': Read-only file system chmod: changing permissions of `digicam': Read-only file system chmod: changing permissions of `lost+found': Read-only file system I can ssh into the server, mkdir [digicam] and "touch" a test file [footest]. $ ll /mnt/HOME1/digicam total 0 -rw-rw-r--. 1 500 500 0 Nov 30 08:06 DSCN0103-scaled.JPG -rw-rw-r--. 1 500 500 0 Nov 30 07:50 footest It appears the problem is in nfs but I don't know where else to look, I've set all the exported files to "777." Obviously I have missed something. The other server, box48 works, it's o/s was installed from the same flash drive Also it will not connect server box8 at boot, I have to mount it manually, the other one, box48, works normally, both are different hardware but box 8 worked until I re-installed SL-6.2. I even re-installed everything and updated again yesterday morning to no avail. Any ideas? Bob -- http://www.qrz.com/db/W2BOD box7

[F17 KDE] Sound cutting out
by Benjamin Smith 03 Dec '12

03 Dec '12

So I have pithos installed (an excellent Pandora client that skips all that nasty flash stuff http://kevinmehall.net/p/pithos/) and Skype. Whenever Skype makes a sound, it cuts out all other system sounds, plays the sound, and then the rest of the system sounds resume. I didn't have this problem with Fedora 16 doing the same thing with the same programs (though I'm using an updated Skype client) Skype is set to use PulseAudio server (local) and there's no option to change to anything else. Pithos appears to use gstreamer though I'm not sure how that relates to PulseAudio. Any ideas where to go from here? Thanks, Benjamin Smith

dynamic ip ok for NFS/LDAP servers? Network Gurus?
by Jack Craig 03 Dec '12

03 Dec '12

Hi Folks, The following strikes me as wrong, but i am Not guru, so i thought to ask this forum where the wizards Do Live! :) Pls consider a configuration with a single host providing NFS4 /home directories for other hosts in a 6 host cluster. Further, openldap is on the same host to provide for authentication on all 6. the architect says its ok to configure all hosts w/DHCP, but i see the ip changing every day or 2 (many reboots due setup). I am a huge fan of static ip for servers, but what do i know?! :( So, Question, is DHCP ok for the 6 hosts in this config, or go static. More, static on server only maybe? TIA, jackc...

Bash - an odd problem using sed or awk or for
by John Horne 02 Dec '12

02 Dec '12

Hello, I have a bash script in which a variable is set to one or more lines of text. What I want is to remove any lines up to and including a blank line (or alternatively to echo all the lines after the last blank line). There may be zero or more blank lines, and the blank lines need not be consecutive. If there is no blank line, then all the lines should be shown. If the last line is blank, then nothing should be shown. So for example the variable may contain: ============ (the '=' are not part of the variable) abc def hijk xyz ============ So in this case what is wanted is: ============ hijk xyz ============ to be shown. I tried something like: echo "$XX" | sed -e '/./,/^$/d' but this didn't display anything. (Where XX is the variable.) I also tried using a 'for' loop but again this displayed nothing: opt="" IFS=$'\n' for n in $XX; do test -z "$n" && opt="" || opt="$opt $n"; done (Echoing $opt after this shows that it contains nothing.) I'm not sure why but even using a for loop just to show it had seen a blank line didn't work either (using something like 'test -z "$n" && echo found'). My understanding was that by setting IFS to a newline, then the 'for' loop should see the blank line and just set '$n' to the null string. We should then be able to test on that. Ideally what I am looking for is a snappy one line 'sed' or 'awk' command to handle this :-) Unfortunately at the moment I seem to be getting nowhere though, even with the 'for' loop.

I am still booted in the 3.7.0-git kernel because it is keeping the disks from sleeping or it is properly waking the disks up before committing reads and writes. However, because of the current kswapd, building a kernel is taking an inordinately long time, so it will be likely 2 or 3 days on my old unicore Athlon64 3700+ before I can boot the new 3.7X

freenx-server with xfce
by Joseph L. Casale 30 Nov '12

30 Nov '12

I haven't setup nx in some time but with rhel it was trivial. With the default key or custom keys, I can't get it to accept a connection. Im using xrdp for now but it has less than desirable side effects so getting nx working would be a plus. Anyone using it with xfce in f18? Thanks! jlc

Multi-Threaded make
by JD 29 Nov '12

29 Nov '12

While building the kernel from source RPM, I run the command ps -ef | grep make in another terminal, and I do see that 4 make processes are running, with each one building objects for a different kernel source directory. However, something else seems to be single threaded which is causing the huge delay in finishing kernel build. I found that when I run top to see the upper-most cpu consumers, I see only one cc1 process at the top. So I ran ps again to see how many cc1 processes there are. Always - just one cc1 process. I would expect to see anywhere from 1 to 4 cc1 processes at a time. But that is not the case. What is forcing only a single instance of cc1 at a time? I hope the devs can have a look at either the compiler tools or the make util.

[F18] How do I set "browse" as the default open type in nautilus?
by thomas cameron 29 Nov '12

29 Nov '12

Looks like Gnome is doing the same thing that Microsoft did after XP. I can no longer set nautilus so that when I double click on a directory, it opens up with the filesystem tree in the left pane, and the contents of my directory in the right pane in *list* view. I used to be able to set a checkbox for 'always open in browse mode" or something similar, but I can't find that in F18 beta. Is that option still around? Where is it hiding? Thomas
