[opensuse] protecting online images
by jdd-gmane 28 Dec '09

Hello :-) I try to protect some online images. I have some ideas I would like to know if they have any chance of being usefull. most simply, I have a photo collection that lay online. public photos are on open folders, private one are hidden behind <directory> apache passwd restrictions. This seems to work. http://dodin.org/wiki/index.php?n=Photo.GaleriesPhoto However, I would like to have some more functions (for example slideshows) using a gallery software. right now I try to use piwigo. The software allows using permissions on images so only the needed ones are public. However most photo in the collections have trivial names (mostly the name given by the photocamera), so it's pretty simple to mind most names from knowing one. For example if I have one public image in the repository, all private names can be gessed and private image viewed. If I add apache restriction, the gallery software dont work. I try to fix this. I don't know any way to allow downloading of public images without giving publicly they URL :-( so I wonder if I could add somewere in the image name a random part making the name guess much more dificult. for example, I could change the name img_2015.jpg to img_2015_489745.jpg, 489745 being random. Do you think this will be enough? is there any better way to have the same result? do you have ideas? I need to keep part of the original name to be able to relate the image to the initial original one thanks jdd -- http://www.dodin.net http://valerie.dodin.org http://news.opensuse.org/2009/04/13/people-of-opensuse-jean-daniel-dodin/ -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse+help(a)opensuse.org

The problem is that these lines (and the similar ones I already found) are very cryptic, and have to be setup for my needs. Right now none of my tests did work. it have to be done simply because I use "piwigo" (open source php script). I'm in relation with the piwigo maintainer (they are french like me) but this don't seems to be a priority for us. but, before I go further, do you think the anonimisation I quoted can be usefull? is there a way to know all the filenames in the folder (of course apache don't list them) thanks jdd -- http://www.dodin.net http://valerie.dodin.org http://news.opensuse.org/2009/04/13/people-of-opensuse-jean-daniel-dodin/ -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse+help(a)opensuse.org

Visitor can and have to be allowed to save the displayed image. But on a list of images, some are private, some public and the names are mostly sequential, so one can change the name on the public URL window and dl the private ones. for example public: image_100023.jpg private image_100027.jpg it's pretty easy to try 23, 24, 25, 26 and find 27 (I already did this myself on some circomstances :-) I added on my generation script this: (for I loop) ran="-$RANDOM-" ; rename "." "$ran." $I ; like this the image names become image_100023-1589-.jpg image_100027-5376-.jpg like this I still can identify the image, but the full name is much more difficult to guess I know it's not impossible to crack, given enough time, but will the robots make such attempts?? I can randomize twice, but is this necessary (it takes time)? thanks jdd -- http://www.dodin.net http://valerie.dodin.org http://news.opensuse.org/2009/04/13/people-of-opensuse-jean-daniel-dodin/ -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse+help(a)opensuse.org

[opensuse] openSuSE Kernel Change that effects Wireless Install ??? (Atheros AR242x will not work)
by David C. Rankin 28 Dec '09

28 Dec '09

Guys, I need a miracle! I have probably installed the madwifi driver at least 10 time on my laptop on SuSE 10.2 through 11.2, but after a new 11.0 install, I am unable to find a madwifi driver that will install and "stay" installed. The funny thing is that the madwifi driver has no problems on the same box when installed on Arch Linux. Even more perplexing, I still have the 11.0 rpms that 'I WAS USING ON THIS BOX' that no longer no longer work, so I know the difficulty is something openSuSE specific with the latest kernel or two. I say that, because the existing drivers I have -- have always worked when I installed them with the original kernel and then updated through each successive kernel. Now, jumping from 2.6.25.5-1.1 to 2.6.25.20-0.5 in one step has left 11.0 in a condition where it will not load the driver properly. I have built and installed from the driver for the following sources all of which worked on this box in the past: madwifi-0.9.4-1.src.rpm # The standard 0.9.4-1 driver madwifi-0.9.4-1-current.src.rpm # The standard 0.9.4-1 driver with the madwifi-project suggested snapshot for 2.6.25+ kernels. madwifi-svn-122109 # this module worked briefly (limited to 1M/s), but then died and despite a number of reinstalls will not configure properly. madwifi-ng_r3366+ar5007-1.4.src.rpm # always worked in the past madwifi-ng_r3366+ar5007-1.9.src.rpm # always worked... madwifi-r3725+AR5007EG-2.2.src.rpm # what I was running on before the 11.2 install madwifi-trunk+r3717-1.2.src.rpm # worked in the past... and I have one or two more around... I even got to the point I was making sure the kernel was 'properly prepared' and that 'all' remnants of the prior installs were removed from the module tree and unloaded by reboot. I would: make mrproper make cloneconfig make modules_prepare make clean in between the package installs. Two notes of interest. (1) the packages are never consistent between where they put the modules in the module tree under /lib/modules/2.6.25.20-0.5-default/.. Sometimes the modules go under ../net, sometimes under ../updates, sometimes under ../weak-updates, but until now it always worked. Second, under openSuSE, I have always had to use the 'ath_pci' module. No matter what, the ath5k driver has never worked -- period. That always seemed strange. Well I confirmed it was strange, because when I checked the module used by Arch Linux on this box, low-and-behold, it was using ath5k??? How does that happen? The errors are pretty much of the same flavor. After the driver is loaded, it complains that the chip doesn't respond: Dec 22 15:00:11 alchemy kernel: PCI: Enabling device 0000:17:00.0 (0000 -> 0002) Dec 22 15:00:11 alchemy kernel: ACPI: PCI Interrupt 0000:17:00.0[A] -> GSI 19 (level, low) -> IRQ 19 Dec 22 15:00:11 alchemy kernel: PCI: Setting latency timer of device 0000:17:00.0 to 64 Dec 22 15:00:11 alchemy kernel: MadWifi: unable to attach hardware: 'Hardware didn't respond as expected' (HAL status 3) Dec 22 15:00:11 alchemy kernel: ACPI: PCI interrupt for device 0000:17:00.0 disabled Dec 22 15:02:18 alchemy kernel: ACPI: PCI Interrupt 0000:17:00.0[A] -> GSI 19 (level, low) -> IRQ 19 Dec 22 15:02:18 alchemy kernel: PCI: Setting latency timer of device 0000:17:00.0 to 64 Dec 22 15:02:18 alchemy kernel: ath5k_pci 0000:17:00.0: registered as 'phy1' Dec 22 15:02:19 alchemy kernel: ath5k phy1: failed to wakeup the MAC Chip Dec 22 15:02:19 alchemy kernel: ACPI: PCI interrupt for device 0000:17:00.0 disabled Dec 22 15:02:19 alchemy kernel: ath5k_pci: probe of 0000:17:00.0 failed with error -5 dmesg: ath5k_pci 0000:17:00.0: registered as 'phy0' ath5k phy0: failed to resume the MAC Chip ath5k_pci: probe of 0000:17:00.0 failed with error -5 ath_hal: 0.9.18.0 (AR5210, AR5211, AR5212, RF5111, RF5112, RF2413, RF5413) wlan: 0.9.4 ath_pci: 0.9.4 eth0: RTL8101e at 0xffffc2000065a000, 00:1b:38:af:36:b8, XID 34200000 IRQ 4348 Basically, I'm f'ing stumped... I don't see any logical reason why what has always worked on this box now refuses to work. I have probably uninstalled, confirmed the uninstall was complete, built, rebuilt, reinstalled until I'm blue in the face. My shortcoming here is that I know not what suse is doing with the module tree and how it is assigning modules/devices. From what I can tell the modules.alias handling of ath5k versus ath_pci may be an issue. In the past, I have always just blacklisted ath5k in /etc/modprobe.d/blacklist to prevent it from loading, but that doesn't work any more. I have attempted to insure that ath_pci is loaded before ath5k with MODULES_LOADED_ON_BOOT`as shown in http://en.opensuse.org/Kernel_module_configuration. Still doesn't help. I need the collective wisdom of the brain-trust to point out where I'm doing the stupid thing that I'm apparently doing repeatedly... (at least I'm consistent) What else would make sense to try or check here? -- David C. Rankin, J.D.,P.E.

[opensuse] Right (safe!) way to grow a VolumeGroup AND its parent partition?
by Ben DJ 28 Dec '09

28 Dec '09

Hi, I've successfully resized (grow & decrease) LVMs within a given Volume Group numerous times. Now I'd like to resize a Volume Group AND its parent partition, and am unclear as to the right/safe method. I have: /dev/sda 500 GB "/boot" /dev/sda1 200 MB LinuxNative, Ext4 (unallocated space) 100 GB /dev/sda3 200 GB LinuxLVM VG0 200 GB "/" (root) LV_A 50 GB Ext4 "/home" LV_B 100 GB Ext4 I'd like to (1) grow /dev/sda3 at the "front end" to use up the available 100 GB (2) grow the VG0 to use 100% of the now-larger /dev/sda3 Since "/" is ON the target partition, I've tried booting from the Opensuse 11.2 Live KDE CD and using its Partition Manager, but it tells me that /dev/sda4 is "in use", and unavailable for edit/resize. Before I go trying more brute-force methods, and subsequently losing my data, I thought I'd ask -- what's the RIGHT way to get this expansion done?

[opensuse] ssh through vpn in openSUSE 11.1
by Istvan Gabor 27 Dec '09

27 Dec '09

I would like to use ssh through vpn in openSUSE 11.1 I have installed cisco vpnclient "vpnclient-linux-x86_64-4.8.02.0030-k9" with no errors. When I run vpnclient it runs w/o errors, eg: > vpnclient connect target Cisco Systems VPN Client Version 4.8.01 (0640) Copyright (C) 1998-2007 Cisco Systems, Inc. All Rights Reserved.

The program hangs at this point. But ssh works if vpnclient is not running. 1. How can I trace if vpnclient or ssh causes the problem? 2. How can I fix this? I can use ssh/vpnclinet combination in openSUSE 10.3, so the issue is not network related.
