[opensuse] DHCPv6 config
by James Knott 06 Feb '11

06 Feb '11

I've just installed the DHCPv6 package, which includes both client and server. While I can find /etc/dhcp6s.conf, I don't see anything in Yast2>Network Services for DHCP6 configuration. The DHCP v4 server is there. I'm running 11.3. tnx jk -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse+help(a)opensuse.org

The device notifier is just that. The automounting is a feature of the kernel and the hardware interface. The device notifier is to notify you and let you choose what tool to run on the mounted device depending on what it is -- data, pictures, audio. It is a user and KDE level function. Removing it will not affect the automounting. This automounting is to do with hardware and call-back to the user space from the hardware layer and kernel, and nothing to do with the automounter and maps. Please don't fiddle with it. -- Excellence is an art won by training and habituation.

Thanks again Anton for your quick reply. I have set up the NFS server on all my Linux systems, and can for the most part now navigate around Linux filesystems via the auto mounted files defined for autofs. I have also left the Samba server running, for the moment, until I can figure out how to use NFS to mount Windoz shares and v.s get Windoz machines to see Linux exported files. (Future project... ) That said, even using NFS to navigate to the mounted USB drive on her laptop, or v.s. for her to navigate to my USB drive, we hit an even worse roadblock. The moment we try to cd into the mounted drive, we can't even get permission to see what is there. I can demonstrate this - Here I cd via a samba mount to the USB drive on my laptop, from my server (or wife's laptop if you like, same results) cd /mnt/samba/marcslaptop/slash/media/My\ Passport/ marc@bigbang:/mnt/samba/marcslaptop/slash/media/My Passport> ls Autorun.inf FOUND.000 FOUND.002 PortableApps StartPortableApps.exe WD Stuff Documents FOUND.001 FOUND.003 $RECYCLE.BIN System Volume Information and I can list out the contents of the top level directory,though I cannot write to it from across the network. Here I tried to cd via a NFS mount to the USB drive on my laptop, and I am not even allowed to get there. Looks like more d$#*m Linux security is blocking me! marc@bigbang:~> cd /mnt/nfs/marcslaptop/slash/media/My\ Passport/ bash: cd: /mnt/nfs/marcslaptop/slash/media/My Passport/: Permission denied <more stuff deleted> > Now here comes the part where I cheat. > > I decided that the the name<->uid on all my machines should be the same. > So files owned by anton on server have the same uid number as files > owned by anton on the laptop.

The only setting I could find, for the device notifier, were settings which control when an auto-mountable device can be mounted. Nothing about where, or permissions associated with said device.

Yeah, like I said, I am guessing on a lot of this.. This setting in particular just boggles my mind and leaves me shaking my head with wonder at how Linux gurus have come to love such obtuse parameters... I have NO idea what devmode, busmode, and listmode mean! Don't want to know, and don't want to have to learn. I just want an easy to use interface with a simple model on how to establish and set permissions! So yeah, I get aggressive about shutting off security whenever I encounter it.

One thing that is interesting is that it appears that if I try to access the USB drive from across the network, it become un-mountable afterwards. Neither umount nor the device notifier can unmount it, saying some process is still accessing it. I have been unable to track down just what process it thinks is still using it.... >> Now, what I want to be able to do is something like the following, to >> copy files from my laptop to my wife's USB drive - >> >> cp *.jpg >> /mnt/auto/wifesLaptop/slash/media/MyPassport/Documents/Pictures >> >> or for my wife to be able to use Dolphin to simply drag and drop >> pictures from her laptop to my USB drive using similar paths... > Which gets back to WHY? > > If you each have /home/<username>/share/ > NFS exported > and<otherusermachine>:/home/<otherusername>/share > NFS mounted on your /mnt/<otherusermachine>/<otherusername> > and a symlink from /home/<username>/<otherusername>/ to > /mnt/<otherusermachine>/<otherusername> > > then you can > > cp *.jpg ~/wifesname/Documents/Pictures/ > > TA-DAH! No not so easy. It is not simply a matter of copying images across, but to do so organizationally. I.E. certain pictures must go in certain folders, and not being able to do that efficiently and directly from across the network is a real PITA for us. > > I know that looks complicated written out like that, but is actually a > very simple and symmetrical pattern.

[opensuse] how to reboot from an ssh install?
by Per Jessen 06 Feb '11

06 Feb '11

I'm installing a remote system over pxe+ssh - once the ssh access is ready, how do I reboot? Note, this is _before_ even starting yast or the installation. I simply want to rerun the bootup, starting with PXE. When I try 'reboot' I get this: box02:~ # reboot WARNING: could not determine runlevel - doing soft reboot (it's better to use shutdown instead of reboot from the command line) shutdown: /dev/initctl: No such file or directory shutdown: cannot execute /sbin/init shutdown: /dev/initctl: No such file or directory box02:~ # Broadcast message from root@pi02 (pts/0) (Fri Feb 4 12:17:02 2011): The system is going down for reboot NOW! box02:~ # But nothing happens. 'shutdown' also doesn't work. -- Per Jessen, Zürich (6.6°C) -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse+help(a)opensuse.org

From there I have a selection of "General", "Device Actions", "Removable Devices", "Keyboard Shortcut" and "Share". The "Removable Devices" leads me to a panel which has settings for WHEN to automount a device. But none have settings for where or permissions.... I have checked "Enable automatic mounting of removable media" and "Automatically mount removable media when attached" Under "Device Overrides" I checked in the column "Automount on attach" for "My Passport" which is the device id for my USB disk.

Anton, again thanks for your replies and thoughts. I see a bunch of replies from you so will try to address each.. As for purpose, I don't think that is important, but we are creating a database of old family pictures and want to categorize them by placing in different sub-directories. (along with other documents) Think about genealogy and family trees and you will get the idea. She works on some, I work on some.... When I get done with some work, I want to move the updates onto her USB drive and this data must be placed in appropriate or new directories as needed, and v.s. for her.. And we take our drives with us to work with other family members, hence the need for portability... > If having the file end up on the USB is critical, can't you do this: > > a) you: mv *.jpg ~/hers/importexportdir > b) she: mv ~/importexportdir/*.jpg /media/sdb1/Pictures/ Yes, but this is a PITA.. that is what we have so far been doing. > > I do recall your complaint about access permissions, but I think that > allowing someone unrestricted access to all of your machine is a formula > for acrimony. > > "Why did you delete that file on my machine" > "I didn't" > Yes you did" > "No I didn't" > "Of course you did, you're the only one who could" > "Well I didn't" > "You must have because I didn't". > ... I agree that reducing security is a risk. But usability is far more important! I think the security wonks keep forgetting that. If security measures prevent one from using their computers, without having to invest hours and hours of time to grok em, then that IS a serious problem! Do some internet searching sometimes and you will find out that a great many users become frustrated with all the security layers and models being used, both in Linux and Windoz. My attitude is to get the computer to a usable state first, THEN worry about security and notch it up as time and needs dictate and allow... The security models of Linux (and Windoz) are both inconsistent and extremely difficult to correct sometimes, and that can render a computer nearly unusable, or extremely difficult at best, for accomplishing some given task... (such as this one...) We have worked out a model on how we want to solve our problem, theoretically transferring files directly to USB drives should follow the model of, and be as easy to perform, as transferring files to internal hard drives. The computer (Linux) should assist the user in doing such a simple task, NOT make it difficult!

[opensuse] No more /boot on RAID1?
by Michael Fischer 06 Feb '11

06 Feb '11

Just installed SuSE 11.3 onto a machine with 2 disks in RAID1. Unlike the 11.1 machine on which I am typing this email, it wouldn't let me install grub, etc to /boot if that partition was RAID-ed. I found: http://forums.opensuse.org/english/get-technical-help-here/install-boot-log… But this confuses me. 11.1 let me "just do this", whereas 11.3 complains. Is it necessary to do the editing of grub or no? Was there some change in this respect between 11.1 and 11.3? I ended up making /boot non-raid, which is slightly unfortunate, as the point of RAID1 (for me anyway) is failover and its kind of nice to think that the bootloader and kernel are "protected" in the same way as /home, etc.. TIA. Michael -- Michael Fischer michael(a)visv.net -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse+help(a)opensuse.org

[opensuse] kde4-4.5.5 kcolorchooser - howto stop it from dimming display so I can 'choose' a color from the screen?
by David C. Rankin 05 Feb '11

05 Feb '11

Guys, This is somewhat comical behavior. When you start kcolorchooser, the screen is dimmed (the same way it gets dimmed when you choose shutdown) making it impossible to 'choose' a color from the screen with kcolorchooser. I know this is probably a setting somewhere that causes this to happen. None of the other apps dim the screen when I launch them. Thus the irony -- "kde4 kcolorchooser can't choose a color from the screen" because it dimmed the darn thing when it launched. Where is the mysterious setting that will fix this? -- David C.

[opensuse] How to install behind a proxy?
by Josef Wolf 05 Feb '11

05 Feb '11

Hello, I tried to install opensuse11.3 behind a firewall. The installer for older releases used to offer the possibility to deactivate automatic configuration (directly after accepting the license). When this option was checked, it was possible to configure the proxy (and hostname and more things) before the online-update was run. This "deactivate automatic configuration" button seems no longer to exist. So, how am I supposed to configure the proxy before running the online update without this option? BTW: Older releases used to offer a shell on virtual terminals. This was convenient in the case of problems. This also don't seem to be available any longer. Why? -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse+help(a)opensuse.org
